LG 42PC3DVA Plasma
Hi every one! My model is LG 42PC3DVA Plasma
Picked up a TV last night by the curb. Seems some one already tried repairing it, but no soldering has been done, some one just opened and closed the back cover :-)
Someone else has a same problem: https://www.youtube.com/watch?v=ALK5achjXlc
This is my TV: http://www.youtube.com/watch?v=pXn33o-jikE
So here what I attempted so far. Once I opened the cover I notice 9 caps blown: C227,C201,C203,C202,C272,C282,C283,C281 (10V 3300uF) I couldn't find the marking for the 9th but it was of the same value in the same cluster of caps. I haven't turned TV ON before replacing the caps for I did not want to blow the board any farther than it already is. After replacing the caps it shows the pic and sound but pictures is flashing and lots of white noise.
I am going to measure the PsU voltages later on tonight and will tell you if any of the are out of normal. But if some one already has a board under suspicion please let me know :-)
I will post higher resolution pics once take out the boards.
Thanks!
