My sansui flat screen volume works but the screen is black and I can't get a picture. What should I do?

If there's no sound at all, switching channels or not, then you may want to check this out:

If it is a LCD TV, and there is a faint picture, it is probably the backlight or inverter board (probably the latter). This is a common problem (especially with PC monitors).
Do an internet search for your model and inverter, you may be able to replace it.
Make SURE you REMOVE the power lead before opening the set !!!!

I lived with it for about six weeks, then took the back off the TV. Just now it seems to be fixed, but I don't know if it will last.

I disconnected the wire leading to the channel up/down, volume up/down and source board, turned on the tv, turned it back off, reconnected the cable, and everything seems fine now.

Change the main board if you have good picture and sound. If you don't have picture and sound, the inverter will also need to be change.

could it be Ch 9's digital signal is not broadcasting right? what is your refresh rate on your tv? 60 or 120hz? if its 120hz, then its more then likely the digital broadcast, if its 60hz I think its your tv can't keep up with their signal that may be at 120hz. Make since??
