    I have a Philips HDTV 42" Plasma doing the same thing. After about an hour of viewing, the top half of the screen flickers in an out, then goes out for a few seconds at a time. Tapping the frame will usually bring it back for awhile, but it appears to be getting worse.

    I have a LG 42" & the LHS develops vertical lines and blacks out only on the LHS the set is 5 years old. Is this the best I can expect, is it time to revisit Harvey Norman where I bought it to get a LCD?

SOURCE: Top half of screen going black.

I've seen this or something similar to this problem on an old lcd screen. The bulb haden't burned out but the system was no longer getting proper 5 volts to the processor chip that processed the image. I ended up desoldering the voltage regulator and soldering a new regulator in it's place it was one with the same amperage so I put a heatsink on it to reduce the chance of another failure.

SOURCE: LG plasma tv has half black screen

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.

Top half of screen blacks out


Today, after speaking to the Sansui Manufacturer representative from Japan. He stated that all you need to do is to turn off the closed caption from the TV remote and not the DVR remote. Black screen can occur at the top half or the bottom half of the screen depending on how it was originally setup during installation. Try this and hopefully this fixes the problem.
