Partial black screen on mulitple (but not all) inputs on panasonic plasma tv

I have a Panasonic Plasma tv model TUPT 700U approximately 8 years old. This particular model has a separate digital media processor with DVI cables connected to the TV. All inputs are through the separate media box. I have Fios hooked up to one input with RCA and digital audio cables. I tried to hook Fios up with HDMI. My TV only has one HDMI input, so my intent was to use an HDMI splitter and then Apple TV, but the screen only showed an image on the top couple inches. The rest of the screen was black. I plugged the RCA cables back in and for about 3 seconds, I had the same result on the screen, but it then reverted back to a full screen.

Sorry but it's time to shop for another tv the cost of repairing would cost almost as much as a new unit.

Sounds like the HDMI port on the monitor has been shorted out.
There are very small fuses on the video board that can be changed, but they are fiddly and you may end up doing more harm then good if you are not sure what your doing.
The fuses are actually soldered to the board...it's not a case of pop one out and pop one in like the glass type.


Hope it helps =)

SOURCE: connecting dvi cable straight to acer monitor

The cable box is probably outputting a resolution the monitor is not compatible with. Computer monitor and television resolutions are usually different, and not cross compatible in some cases.

For example, wide screen monitors are usually 16:10 aspect ratio, while TV is usually 16:9 aspect.

The AL2216wbd is a 1680x1050 display, while HD TV is either 720p (1280x720) or 1080i (1920x1080).

If your cable box is set to 1080i that would be too high for the monitor. You will need to set it to output at 720p, and even then you will probably get a vertically stretched picture since the monitor has a taller aspect.

SOURCE: No DVi input, then computer goes to sleep

Hi publicworker,

I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.

How to do that:

  • right mouse click on the desktop
  • select graphic options
  • output to
  • extended desktop
Maybe some changings/modification will help you too.

Hello, I have a 2 years old Panasonic Viera plasma TV and there are many horizontal lines going from the top of the screen to the bottom... No matter which input is used...


You're discussing about the 'supply HUM' I assumes. Check all the external connection to TV inputs for firmness first. If all are found OK, check by replacing all the filter capacitors at its main power supply regulator board. In fact, replace the power supply board as card basis will be the best.

Your plasma cover screen should be glass, not plastic. I have no knowledge of Panasonic or any other manufacture that made a plasma TV with plastic....all plasma TV's have a glass cover. Clean the surface with a rubbing alcohol solution and a cotton ball.

Plasma tv screen goes black once you turn it on. Only sound


I have a panasonic TH-42PX60U plasma TV. When I watch TV programing I have no problems, or with the DVD input. But if I switch to another input, be it video game (PS2) or vcr the screen sometimes goes black and the red power lcd light next to the power switch flashes. Holding the power button in for a few seconds will shut down the tv. Then I can turn it back on and it may operate normally again for a undetermined period of time, before the screen goes black again. This never happened when new. The tv is about 1 year old. Any ideas on this problem? Thanks Ernie
