    If you haven't used tv before you will need to scan for channels. Select Menu, Setup, Auto and wait until it's finished scanning

Hello Jacques,
This type of failure on this plasma is due to a defective IC that is mounted underneath the black heatsink located on the Ysustainer board. In order to isolate this failure to the Ysustainer board, I would suggest to check the fuses at location FS2 and FS3.

hi gsgoer
Just read the description of your problem and without being there with measuring tools;
The power supply estimate sounds like a fair evaluation of the problem in your model.
Good luck with the repair.

LG 42PC3D Plasma: No picture, good sound


One of the SUS panels will be defect.On these panels you will find several fuses,the panel with the broken fuse must be replaced.
Sus panels are the panels with the big cooling blocks.

Sound but no picture


It's very likely the fuse on the Y-sustain board may have gone open circuit due either a fault with the sustain board or the buffer board. If this is ok then check if your Vs & Va voltages are present when switched on if yes you may have a fault with the control board.

BROKEN PLASMA SCREEN


Unfortunately, you'll have to replace the whole plasma screen to fix it. It's the most expensive part of the TV.
The web link below is the cheapest place to get a new screen.
http://www.shopjimmy.com/catalogsearch/result/index/?q=lg+screen&p=2

If your TV is model 42PC3D, they don't have your screen in stock right now. If you look at the other screens that are 42", the are $350 and up. Other web site will charge more than double for the same screen.

Sorry to give you bad news.
