Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

Can you hear the sound of turning on?

I think that you need to replace the main board.

SOURCE: sound yes, but no picture on tv

If you have sound on the stations this is a problem in the display. Take bright flashlight and hold it against the screen. Look for an image around the edge of the flashlight. If you see an image then it's one of three problems;
1) The inverter board is bad.
2) The CCFT (cold cathode fluoresent light) are bad.
3) The power supply to the inverter board is bad.
Someone knowledgeable in electronics can replace the bad part(s).

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.
