Question about Sony KV-32S25 32" TV
I WAS LOOKING AT TV AND IT TURNED OFF AND WON'T TURN BACK ON. OUTLET HAS POWER BUT TV HAS NO SINN OF POWER , SOUND OR PICTURE.
Ok your going to need a VOM meter and a soldering iron (25 to 53 watt, not a soldering gun). By no sign of power Im guessing that there is no click or any kind of "electronic" noise from inside the set. Ok, safety first, unplug the set and once you open it stay away from the high voltage anode wire that goes to the CRT (picture tube). In side by the power supply locate a resistor that should be at location R607, it is colored white and has a value of 0.1 ohm. It is most likely open, if so then most likely Q601 and Q602 are shorted as well, you will have to replace them and it is very important to also replace the following (shorted or not) R644 6.8ohm I think 1/4 watt and VDR601 VDR602 and VDR603 One of them is color black and the other two are green. I think VDR601 is the black one but dont quoat me on that. Next go to the Flyback transformer largest transformer in there (roundish in shape) near it is the Horz out transister I think it is location Q591, check with your VOM to see if it is shorted, if so replace it. Once you have that done solder the pins on the flyback and the Horz drive transformer, again dont quoat me but I think it is location T503. If you have a ESR meter check the electrolytic capcapscitors. Hope this helps! Good luck! Don
