LG 42PJ550 doesn't turn on

[steffunaro]

Hi,

I'm trying to fix my mother's tv. LG plasma 42PJ550
It doesn't turn on. It makes a click sound and there's nothing on the screen.
I have read this post and my problem is the same, the pictures looks exactly like my tv. http://www.justanswer.com/tv-repair/...html#re.v/327/

So I made the same measurement that Dan asked him to do and here it is.

I've set my meter at DCV 300 (my meter is not very precise to read, so numbers are approximative).
Top left connector, from top to bottom:
190
190
0
0
0
60
60
0
5
5

Bottom right connector, from left to right:
20-0-2-2-0-0-2-2-2

And when I disconnect the top left connector and do the same reading on the board, I get exactly the same results.

Can someone help me diagnose the problem ? Is it the power board ? I've seen a lot of people selling some repair kits to repair the board instead of replacing it, it's a lot cheaper but I'm not sure I can solder, I've done it once and I lean fast, so maybe I could try if I find the right kit.

Thanks for your help!

Stef

Re: LG 42PJ550 doesn't turn on

check the 22 ohm wirewound resistors top right of the power supply-they fail due to being under-rated...use 7w or above.

If those voltages you posted are permanent then your power supply is generating both vs and va voltages. Therefore the 2 wirewound resistors should be ok.

If you darken the room is the panel glowing?
