No sound or pic

Sounds like the t-com board is bad.

How do you know it is on if there is no pic and no sound?

I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

Go back into the TV Settings and under Sound or
Picture make sure you do not have SAP-selected

Had the same issue sound but no picture, try wiggling the connections to the back of the tv, if that does not work try using a different hook-up, I ended going from the component jacks to the DVI hook-up and this took care of the problem, hope this helps!!

reset the settings to factory default on the projector. make sure the resolution matches.

this happens to mine aswell, does your camera playback sound on your videos, as when waching my videos there is no sound. please help.

Normally it is the scart lead not in properly or faulty.Your normally get pic no sound or sound no pic.I hope this helps.
