No picture but sound on panasonic plasma

I have a panasonic plasma tv model no. Th-42px600a. today i after watching a movie on hdmi mode, i switched to digital tv mode and there was no picture but sound. After pressing the 'i' button on the remote nothing showed up, not even the setup menu for picture and sound. i assume it is the problem of the inbuilt tuner as normal tv worked and hdmi mode worked. is there a problem?

Unplug the TV and disconnect any HDMI cables to the set. If the issue goes away there is a possibility that your HDMI source is causing the problem. Anything on the HDMI can cause odd problems with the TV since the serial data and serail clock lines are routed on HDMI. Those are the 2 commmunication lines used throught the TV for operation so anything HDMI that might load down one of those can cause issues.

My panasonic high definition plasma television, Model # TH-42PX75U, I CRACK IN THE SCHREEN, HAS SOUND BUT NO PICTURE . CAN IT BE REPAIRED WHAT SHOULD I DO?


It is possible to be repaired. Though I don't know about the availability of the screen. How long have you owned the tv? Your best bet may be to sell it for parts and purchase a new tv. If you have any questions or need any other assistance please let me know.
Thanks,
Lee

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

Well don't tamper with it just return it, there is serveral problem that may cause this, most likely it is the power supply board.

You need a audio cable for sound. HDMI cable is only for picture. I use the comp 1 plugs myself, better picture. I found with my TV that the HDMI cable is only good if you have a digital box for it. You can also use the plug to hook your computer to off your graphics card and watch downloaded movies on.
