SOURCE: Panasonic TH-42PX60U PLasma - 1/2 screen blacked out

If the screen split is exactly 50/50 top/bottom You are not getting SU or Scan Upper drive.
These are lovely set to work on.
Most likely is SU board itself - Not repairable just to be replaced.
Sorry I work in the UK so I can only guide that the UK part is around £30
SU may have been damaged by failure if the PDP (Plasma Display Panel) but is 9 years only had 2 screens damage the SU board.
There are several setups to do after fitting a PDP. If you don't have the service data - Do not risk it, Reduced life of the Panel and a safety risk.

This is beyond consumer ability to repair. Please have it looked at by a qualified electronics service company.

I have a Sanyo 46 inch flat screen hdtv purchased from walmart aug. 31rst, 2008. Sure enough, 13 months later my tv is having picture problems and getting worse. It started having portions of the screen...

I have the same problem, my television is faded black on the left side with lines on the left top side. I have had the 46 inch unit for 1 year and 7 months. I am planning to write a demand letter to Sanyo and then taking them to small claims court woth evidence that this is a common problem with their units that they know about and is not trying to remedy. Also the Attorney general in Texas should have an interest in them (Walmart and Sanyo) selling these defective proucts in the state.

Visio LCD TV - Partial Picture blacked.

Hello! I have a 32" Vizio LCD...within 30 minutes of the tv being turned on, black lines start running through the bottom half of the screen and eventually blacking out the bottom half of the tv screen. It also doesn't have anything to do with the ratio as I have tried that. HELP!

Picture won't come in clear until TV "warms up" for 15 minutes or more

Change the capacitors first per the instructions in the link below. Symptoms could be anything from high-pitched hum to no picture at all. On these defective models, I would start at the caps and work back. It won't hurt to replace them anyway.
