Question about LG 50PC3D 50 in. Plasma Television

HI, I have no picture of sound. When I turn the TV on I get a series of clicks then the light turns from red to green and flashes green 3 times. I checked the power board and found 9 bad caps and replaced them but still no picture and the TV does not come on. Please help.

3 blinks indicate a failure in the power source.
You will need to test it, identify the failed output line (most likely it's the 3,3 v one) and replace the failed parts - most likely the rectifier.
Use this manual for a more precise troubleshooting

Sounds as though the system may have overheated. Do you regularly check the filters and clean them? An airduster can also help to blow dust out of hard to reach places.

the green is the reboot process and is normal.
the red light is an error code indicator.
count the blinks of the red light...it cant be 30 times (I think)
it will blink a sequence, pause, then do it again for a total of three times.
count carefully, it gives you three chances to catch the number it is blinking.

Telly on but no sound orpicture


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL2100 you can find it here http://www.discount-merchant.com/Sony-XL-2100U-TV-Lamp-p/sony_xl-2100u_replacement_lamp.htm?Click=48173 .Have a blessed one!

Samsung HLP4674W - changed bulb - still no picture - lights flash


If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.

TV has sound but no picture


It is possible one of the internal fuses blew out.
It could be a bad horizontal outut transistor.
It could be a bad secondary of the power supply went bad
And many other things.
If it's just a fuse, it won't cost much, but a lot of them do not look like you would expect a fuse to look like.It might be a little yellow, green, or gray rectangualar box shaped part. :D
