A fent emlitett monitort szeretnem szamitogephez hasznalni.Az interneten talaltam leirast,hogy a videokartya mely kivezeteseit kell a monitor hatuljan talalhato 8 polusu DIN dugohoz csatlakoztatni. A kovetkezo bekotest hasznaltam:Segitsegeteket elore is koszonom. Udv.:bogyoEgy retro 1988-as commodore 1802D-es szines CRT video monitor javitasaban kernek segitseget. Mikor hozzam kerult, ket problemaval szembesultem. Az elso, hogy nem voltak szinek. Csak fekete feher kep. A neten kutakodva szerencsere talaltam ra egyszeru megoldast. Ez most jo lett. A masik problemara meg nem talaltam megoldast. Van beepitett hangszoroja. Az audio bemenet RCA aljzatara barmit is kapcsolok ra, nem szol. Egy 10 labu ic felelos az erositesert. Kideritettem, hogy nem kapja meg a 12v-os feszt. Az IC a D807-es EU1-es diodan es az R830-as Kimertem, hogy ez a dioda romlott el. Sajnos ezt a fajta diodat mar nem lehet beszerezni. Ajanlottak helyette a HER105-os diodat. Diodat beforrasztottam, majd bekapcsoltam a monitort tesztelesre. Az R830-as 1o1w ellenallas elkezdett fustolni, majd abbamaradt. Ezek utan a monitor nem adott kepet, nem kapcsolt be. Kiforrasztva a diodat, ismet bekapcsolt, es adott kepet. A diodat az eset utan megmerve mukodokepesnek talaltam, nem lett baja.http://ck-buhgalter.ru/userfiles/dimage-z6-manual-pdf.xml

Az ellenallas termeszetesen tonkre ment. Meg egyszer megprobaltam a biztonsag kedveert egy masik HER105-os diodaval, es egy nagyobb 1ohm 2wattos ellenallassal, de az eredmeny ugyanaz volt. Most megakadtam, es nem tudom hogyan tovabb. A service manual hiba levezetos reszet hasznaltam kiindulasi pontnak, de ott is ugyanezt javasoltak a dioda es ellenallas cserejet ha nem kap feszultseget az audio IC.

I need to change all potentiometers which are located in the rear part. Someone knows the values and type? Thank you.Q401 Q701 Q702 Q703 Q704 R435 R436 R437 i need the colour bars on the resistors.and whats written on the transistors.if your unsure about the resistors could you take a high res picture in close up of them in good light please.Thanks for the information of the potentiometers. On Thursday or Friday I will send you pictures of what you need.If I do not get the appropriate potentiometers, I invent something to solve it. Thanks for your interest. FranCheck if it is the same model.Tomorrow I seek information.I understood his clarification about the manual, thanks. Excuse my English is basic. But now I wonder, I am not sure if my monitor has a TTL RGB input!But now I wonder, I am not sure if my monitor has a TTL RGB input! Roy, Look at my image This nice, no.What kind of switch is. The original is completely destroyed and not working. This is a full picture of the motherboard to give you an idea of the differences. The Commodore 1084 was a Philips product and this is the typenr.I knew that D2 is installed daewoo electronics. You think it's the same schematich? Picture and sound are both still perfect.Also, while the sound is still good, there is an low level buzz emitting from the speakers.Teardown books? Anything like that on the internet.http://cinepopulation.fr/img/dimage-z2-manual.xml I have never done any work on a CRT screen before, and would like to know what I am doing before I do it. I am guessing there will be parts that need cleaning and replacing, not to mention fixing up that slightly lopsided screen on the 1801. So if anyone knows of any good resources, or has good hints and tips for a CRT newbie, that would be great. Thanks a lot for that mate. Welcome to Amibay.com.

Btw,i guess u meant a 1902(c64 monitor?) they have the same troubles usually. mike But it no longer flickers. Next step, dumpster! But it no longer flickers. I'd be willing to bet this is one the most common failures. I have a 1084s and a 1950 that do this. Haven't gotten around to repairing them yet. You seem to pitch anything. Anyone else concur? Any help would be much appreciated.My arm ached for a day. My arm ached for a day..and this is why I'm more than happy to toss them when they give me trouble! He can repair such a monitor. How many of our club monitors have been repaired by him.Anyone else concur? that is sure a possibility, but it makes me ask what caused it to fail suddenly?,you may have other problems causing it and adding another vertical ic may just fry again.soldering the flyback etc shouldn't do that.I really don't know enough about monitor repair to help much.

I have on the bench a Commodore 1084 Monitor which I am in the process of repairing for a friend. He said it was fine when put into storage a few years ago, But now dead. He replaced the main smoothing cap himself. Fortunately the service manual is available online and working my way through the schematic, I have managed to bring the monitor back to life. The 12v power rail was dead due to a short circuit Cap C605 220uf and a faulty 7812 Voltage Regulator I402. However another fault has presented itself. To test the monitor I am feeding it with a composite signal from a DVD player. The picture is OK for about 30 secs then black horizontal lines start appearing about every inch with odd bursts of colour.http://mitchellbrothersloghomes.com/images/commercial-manual-floor-sweeper.pdf I have attached an image showing the fault Its been about 15 years since I worked on anything CRT related, any assistance would be much appreciated. Thanks in advance DomAlso, the disturbance is about 5 times the vertical scan frequency, an unusual rate as such a signal at those intervals is not normally found in monitor circuitry. While it is possible this fault is in the monitor, most likely the video source (your DVD player)you are feeding the monitor from is defective. First thing to do is to try a second video source, or second monitor. If this is a monitor fault, it would be easy to find the cause of this with a schematic for the monitor and following the video signal from the video input with the scope to find where the disturbance is introduced.That monitor almost certainly has RGB-in capability, if dom is already using a fully wired SCART lead between the DVD player and monitor then it may be useful to try RGB-in instead of composite-in. You would need to enable RGB-out in the DVD player's menus as well (the default will be for composite out).Looks like hum bars to me, you probably have more faulty caps in there.As I mentioned, this rate would be an unusual frequency to find as a signal inside a monitor, but could easily appear out the output of a DVD or VCR etc, like the signals you can see when you fast forward or shuttle a DVDs or vcr tape.Not made much progress. I am now feeding the monitor from the original Commodore Amiga via RGB. The colours have now stabilized, But the black lines are still on the screen, they seem to vary in width and frequency I have checked the voltages around the fly back transformer, all seem to match with the values in the service manual. I have also replaced the electrolytic caps around the horizontal and vertical circuits. I have attached a screenshot of the schematic showing the caps I have replaced circled in red. It will be Monday before I get another chance to work on the monitor. Thanks again DomSo I will make some suggestions how this could happen. Wherever this pulse is coming from you also know know it was affecting the pal decoder circuit too(because it caused a color phase error when you were feeding the monitor with composite video, of course that is now gone on an RGB signal). Since that circuit is in a completely different section of the monitor, it now appears likely this pulse is on one or more of the the power supply rails. To get the three guns of the CRT cut off together requires the pulse at the three cathodes all going positive at the same time. Or the could be an abnormality in the V blanking signals that also are normally common to the three stages. The other way the three beams could cut off together is if there was a negative pulse on the CRT grids (which are normally common as one control grid in the CRT's gun). Sometimes, depending on the design, blanking pulses can be introduced there rather than into the video amplifiers. It would be easy to find where this problem was, with the scope, working backwards from the CRT's cathodes (once the grid circuit was excluded) and finding where it was coming from, either injected into them as a faulty V blanking Signal, or a a large glitch in the power supply rail.Try getting the unit into a place of complete darkness, let your eyes adjust and see if you can actually see anything flashing over.Or alternatively feeding the DVD composite output into another display. In other words, are you sure its the monitor and not the composite output on the DVD player that is acting up?Try getting the unit into a place of complete darkness, let your eyes adjust and see if you can actually see anything flashing over. So it cannot be the LOPT or any signal the LOPT could produce being coupled into the signal circuits. It is interesting how sharply and well all CRT beams turn off and on again for the short period of this defect. That makes me wonder if the aberrant signal is in the CRT's blanking circuits. But that theory would not easily explain why on a composite signal it loses color lock immediately afterwards, which suggests the power supply has a large glitch in its output. It would be very easy to solve with a scope. The other interesting thing is how the time of the disturbance is only about one scanning line or two when it occurs across a frame and the amplitude of it is not disminished over time. For example if there was a coil somewhere ringing at 5 times the vertical rate after the vertical blanking interval, one might expect the disturbance to get less as the vertical scan progressed. So the defect almost looks like something you would expect if you injected a regular narrow rectangular pulse into the signal circuits. It will most likely be on the power supply rail, but there is always an off beat chance a sub-circuit has failed and is oscillating locked to the vertical rate, assuming those black lines are not rolling.These things would be obvious from a video of the fault, but a still photo gives less information.

I have never debugged electronics before and do not know where to start or how. I have an analogue oscilloscope, signal generator, and a multimeter available. I also have an assortment of electronics components but they are of low wattage rating. Specs The TV in question is a Commodore 1084S-P monitor What happened: I was turning my Commodore 1084S-P monitor into an oscillographic TV following this guide. I tried to turn the TV on but got only a high pitched sound. The TV circuit board detected that there was something wrong with the deflectors and refused to power on. By reconnecting the horizontal deflection coil driver to the TV circuit I was able to get a horizontal line on the TV screen. I concluded that somehow the horizontal dummy coil was not enough to fool the TV circuit. I measured the inductance of horizontal deflection coil (1800 microhenries) and wound an inductor of about the same inductance (2000 microhenries). I reconnected the vertical deflection driver cables back to the TV circuit to create a vertical line and turned the brightness control all the way down to avoid damaging the CRT. I quicly turned the TV off to prevent damage but upon restarting the TV just gave a high pitched whining sound. The horizontal dummy coil inductor was very hot. I forgot to measure its resistance (2ohm) and add a respective sandbar resistor. The TV wont turn on. Not even when I reconnect the deflection yokes to the TV circuit. Instead a high pitched noise ensues. Why I want to repair this TV This is a hobby project and I am looking to get better at electronics. When I started this project I knew next to nothing about electronics. I think repairing this TV will be an excellent learning opportunity. I have trouble reading this schematic. It would be of great help if somebody could indicate (possibly with a red marker) the horizontal deflector circuit on this diagram. If you don't have an ESR Meter, then just replace it as a matter of course. You should also check all of the diodes for shorts and reverse leakage. The high ohms setting is the punch-through test, and it will determine if the part has reverse leakage. When testing: Select diode test on your meter: Place the positive probe on the anode and the negative on the cathode. Next, lift one leg of the diode out of circuit, set your multimeter to its highest ohms setting, then place the positive probe on the cathode and the negative probe on the anode. If you get a reading, then there's a very high possibility that the diode is leaky and would require replacement. Place the positive probe onto the base pin and negative probe on the emitter or collector, either one should read about 0.600 plus. Make sure you check the emitter with respect to the base pin, the same with the collector. To get a precise punch-through test you really need to lift two pins of the transistor. It would be much easier to remove it entirely out of circuit. Now set your multimeter to the highest ohms setting. Place the negative probe on the base of the transistor, then the positive probe on the emitter, then on the collector. You should get no reading at all. Now place the positive probe on the emitter and the negative in the collector. Then reverse it (i.e. positive on the collector and negative on the emitter). Once again, you should not get a reading. Please let us know how you get on. Regards, Relayer Btw, do you know if it is normal for the horizontal deflection circuit to appear as an open circuit. I measured the resistance of both the horizontal and vertical deflection circuits and it appears to me that the horizontal circuit is open whereas vertical is not. I measured the resistance of both the horizontal and vertical deflection circuits and it appears to me that the horizontal circuit is open whereas vertical is not.If so, there should not be an open circuit condition. Both should show continuity. Regards, Relayer Could this diode be the culprit. D143 is a BYD33D diode. What I tried to communicate was the scales on my multimeter. 2k ohms for diode check and 20M ohms for punch through test. Since the monitor won't turn on, your problem most likely is in the power supply. An overload probably happened as you report: It might be a component going open or closed. An oscilloscope is useful to observe the power supply waveform. However caution is required if you were to plug both monitor and scope directly into house voltage. There's the possibility that their power supplies are wired so they create a current loop, and a path for heavy current, resulting in short circuit. It's easier if you plug one unit into an isolation transformer. Extreme care is required or else more components could break. D143 is a BYD33D diode.You would really need compare it with another one of its type. I'm on the side of Brad in that D143 is actually OK. Unfortunately I don't have a controlled avalanche diode in my stocks to see if I would get similar readings. As Brad suggested, the power supply seems to be the culprit in it behaving the way it is. One thing I'd like you to try next is to place a shorting link across the horizontal output transistors base and emitter. (TS467) This will eliminate the flyback transformer as being a load problem on the power supply. This should tell if the Flyback tranny has shorted turns. This isn't a guarantee, but should give you a rough idea. If the unit still whistles, then remove the short and measure the voltages around TS467. If the 147 volts is missing on its collector then the power supply isn't doing its job. Measure the base to see if it reads around 0.7 volts. Be careful when measuring. Also make sure you use a good ground point for the negative probe on your meter. If you do have missing voltages, next step is to partially isolate the power supply from the rest of the monitor. We need to concentrate on the 147 volt rail. You need to lift the cathode end of D141, which is located near pin 10 of the chopper transformer of the power supply. You must obtain at least a 75 watt incandescent light globe (NOT a LED type). You'll be using it as a dummy load. You need to attach two wires to the globe and I strongly suggest you insulate the base of it with electrical tape so you don't accidentally electrocute yourself. Once the above is done, solder one wire of the globe to the anode of D141 and the other end to a good ground point on the cold side of the suppy. The negative side of C144 (47uF 250V) will be fine. If the whistling stops, then the problem won't be the power supply, it will be somewhere else. If it continues to chirp its brains off, then we need to delve deeper into the PSU. Regards, Relayer Their BYV96E's which showed open circuits on punch-through. Therefore there's a good chance the one you have has reverse leakage. You need to replace it with an exact type or an equivalent. I apologize for the mistake. One thing though, replacing the diode may not be the solution, but there's a good probability that it is the problem. Regards, Relayer Silly me assumed it was in the primary of the power supply. Whereas it's providing a minor voltage rail to the rest of the monitor. I still say that D143 requires replacement, as this will at least eliminate that part of the circuit as the cause of the problem. But probably unlikely. I await your findings. Especially if the PSU is delivering the 147 volt rail. Regards, Relayer I will keep you posted as soon as there is new findings. The unit still whistles. I will next measure the voltages around TS467. But first, what do you mean by a good ground point. Would the grounding wire around the CRT be a good ground point. Additionally, I noticed two more transistors (TS152 and TS132) on the PSU which I have not tested. I had previously tested only transistors TS117 and TS121. I will check these new transistors too. Like that dreaded Coronavirus. The unit still whistles.One is within the primary of the power supply. Everything to the left side of the chopper transformer (T101) and through the centre of the opto-coupler. All to the right of the transformer and opto is the cold side of the motherboard. When measuring voltages on the primary, your ground point MUST be within the primary side. i.e. The negative side of C122 as an example. DON'T use anything on the secondary side. When measuring the primary side, be very cautious, as the voltages can kill if you touch anything, as it's not isolated and can deliver a hefty punch. Since it's pretty much directly connected to mains. If you have an isolation transformer, that should protect you, as that will isolate you from the mains. When measuring the voltages on TS132, you'll find that the base and emitter have the exact same voltages. I think they are incorrect. Otherwise the transistor is actually turned off if you follow their indicated voltages. One last thing, what happens if you disconnect the deflection yoke connector. It should be a largish four pin type. Does the monitor stop whistling. Regards, Relayer By continuing to use this site, you are consenting to our use of cookies. The Long Hedge The long hedge protects against a rise in input costs such as those incurred by a packer procuring cattle and hogs, or a producer who needs to insure against higher feed costs. When you plan to buy a commodity, you can use a long hedge to lock in a price and protect against price increases. This flow chart shows the steps taken in a long hedge. Buy futures contract then Sell back futures contract then Buy commodity in cash market The Long Hedger Plans to buy a commodity and buys a futures contract to lock in a purchase price and protect against rising prices. Long hedge example: Suppose it is December. A packer wants to protect procurement cost for hogs purchased in July. What if prices had fallen. Note: When the packer quotes a forward contract price to buy your lean hogs, he will offer a weaker basis than will most likely occur at contract delivery. Since there is a risk in the basis, the packer builds in protection by lowering the contract offer to you. Futures Cash Flow You have to look at the cash required for futures trading. Before considering some practical hedging examples, we will take a look at the finances of hedging: The performance bond, or good faith, deposit Broker commission The exchange clearing house requires that clearing members deposit performance bonds to guarantee performance on their customers open futures contracts. Individuals trading in the market make the deposit with their brokerage houses. Performance bond The amount of money or collateral deposited by a client with his broker, or by a clearing firm with CME Clearing on open futures or options contracts before a customer can trade. The performance bond is not a part payment on a purchase. When you sell a futures contract, you do not receive payment. Instead, you deposit a performance bond (money) with your broker to guarantee payment of immediate losses you may suffer. The value of your contract is calculated on a daily basis.
