I'm hooking up an APEX Digital TV and when playing a DVD, the picture is fine, but there is no sound. When on TV mode, sound is fine. Suggestions on how to fix this?


  • Turn everything off. Turn on TV and Select dvd input (Source). Wait 10 or so seconds. Turn on DVD player. Works for me with similar problem. Good luck -

My bauhn TV screen stopped working. DVD plays sound but no picture. Can the TV be reset or rebooted


You can try unplugging the units--no picture often means the DVD has a dirty or failed optical unit.

I have a 32" TV/DVD combo westinghouse LCD TV. When I turn the TV on I get no picture. There is sound. DVD player does not show picture either, I have sound but no picture.


This is a backlight or inverter Problem. Based on the model you have, I am guessing the inverter is defective.

Inverter is defined as the board in the TV that supplies power for the flourescent lights inside the LCD TV that provide backlighting for the TV's Display

I had to attempt multiple times turning the TV on to get a picture. The sound was fine. This kept happening when I would go to turn on the set the TV kept playing fine with picture & sound but after the 2nd attemts I turned it off & then tried to turn it back on which took multiple attempts, it kept playing for a few minutes then the picture went out but the sound was still there.
The set is not yet 2 years old.

Picture


yes it could ba the cable itself even, but i suspect more the tuner circuit or tuner itself may have bad solder connections. Here is another test for you to try, plug another dvd or vcr, or xbox etc. into the back, using one odf the inputs. See if this works like the built in dvd. if so it will be more likely bad connections in the tuner or surrounding circuit. good luck.

No picture while playing DVD or VHS tape


Your unit has it seems to have developed a video problem. it could be in the video switching IC or the video processor. Its going to need a trained technician, who knows how to use an ocilliscope to find the video problem.. Good Luck
