Vs-60609 my color is gone just black &white what might be the problem
The color crystal may have a bad ground and needs resoldered. But that is not the only solution. You will have pull the convergence board out and rework this. I mean you will have many, many bad grounds here.Start with the convergence board, IC STK 393-110 needs resoldering, replace capacitor (location number and value of capacitor) C8C05 25 volt 100Mf,C807 25 volts 100MF, C2C86 25volts 10 Mf, C2V17 25 volts 10Mf and C601 350 volts 1 Mf. Also resolder jumper cable socket pins behind the tuners, TU1A02 (says RF). Resolder jumper sockets CE,RG,DM, VU, DP, EL,PM, PF.Other socket connections include KC, KB, AV1, AV2. Resolder IC 2P30. All of these are located on the signal board. This board has all of your RCA and RF connections. Next remove the power supply board. This one has the flyback transformer, solder the connections on the transformer as needed. Resolder jumper connections DM, DT. Diode 983 will need resoldered and the resistor( R522) is running hot and the colored stripes are all gray. Replace this resistor with a .82 ohm at 2 watts. Replace capacitor C935 which is a 35 volt at 47Mf, this one is bad. Check capacitors C551 and C531 which are 160 volts at 2.2Mf. They are mostly OK but can go bad any time now. Q533 is a high speed switch it may be good, you should resolder this. The cross for this would be a NTE 2361. I don't believe this one is bad. Leave the original. and resolder the Horizontal transistors Q5A02 and Q5A00. Also, there is a capacitor next to the high speed transistor switch (Q533) that may be weak by now. I don't know the value off hand, only that it is near the Q533 transistor. It is an electrolytic (looks like a miniature can). Well there is a lot to consider, but this TV will operate for a few more years. Find a hobbiest or TV tech to do this if you can not. I know, its a lot, to return the color on your TV, but this is what it will take.Show them this note. Thanks for asking and show a few hands of support.
