The part is a horizontal output transistor 2SD2578. There are probably other parts shorted such as a flyback transformer and or power supply components. I would not try to fix this one if I were you. Sony TV`s rarely blow just one part. Usually you have a handful of bad parts. Sony`s can be difficult even for experienced technicians.

D2578 is a transistor that often runs hot and burns out. Replace it with 2SD2539 transistor that runs much cooler. That should solve your problem.

However, if it has burnt out due to another component causing a voltage problem, it may only work temporarily or not at all.

I'd guess that the odds are 90-10 in your favor and it should not be expensive - so it is definitely worth a try.

You can get the 2SD2539 transistor from a TV parts dealer or from Sony. It does not have to be made by Sony. Parts dealers will be much less expensive than from Sony. Google "TV-Parts" near (your zip) code or look in the yellow pages under that heading.

Good luck!

Sony KP-57WS510 red light blinking 5x


Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

KP-57WS520 Sony Projector - No picture


Hi,
5 times blinks shows incorrect white balance (AKB) error. TV needs Screen Volts (G2) adjustment.
Take off lower front panel, find Focus Block that has 6 control knobs, adjust Screen volts of each CRT (red-green-blue) and problem will be solved.
Be Careful while working in TV.
Let me know if you have further question.
Thanks.

when it goes green, your green picture tube is shorting out, replaceing the green tube costs alot of money. these sony's had alot of bad tubes, the red and blue are probably going out too, it will cost alot to fix this, at least $500 even if you find good used picture tubes to put in it.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Sony - Projector TV won't turn


Sony TV;s will give a service code, count the blinks, eg; 2-6, light will blink X amount of times, hesitate & blink again so many times. Count and report back but, I would recomend to unplug the TV's power cord, to reset the TV's system. Unplug for at least 3 minutes. I hope this was helpful.

Cant fix my sony KP-53S65


If the TV will not turn on and the red light blinks on the front of the set, it means that the microprocessor has detected a problem in the set and shut the set down. It then blinks the red light a certain number of times, and the number of blinks is the code for why the set has shut off. How many times does the red light blink before repeating?
