I have a 1.5 year old Sansui 19' LCD flat screen TV in my dorm room. My TV has everything set on analog idk why and it only finds 3 channels doing set up. Even when it finds them my picture is not clear and there is no sound on my TV. Where are the rest of my channels? No one else in my dorm has this problem.
Set the Channel scan for cable input, not antenna.
Testimonial: "How do I do that?"

My 32D40U would turn on for 5-10 seconds (Please Wait would appear) and the screen would go black. Sound Normal. It would also sometimes do this after running 5-10 minutes. I read somewhere that the inverter board would come loose and lose proper ground. I took the set apart, removed the board, and cleaned up the grounding points. I reassembled using some copper paste on the ground points and LockTite on the screws. I used some contact cleaner on all the connectors going to the board. I noticed two cables that are covered with copper shield tape where too tight at their connectors and repositioned the tape to give them some slack. The problem hasn't occurred since the fix.
