    The picture went out but I can still hear sound. Opened and flipped a switch on the top middle board, suspect power board of some kind, capacitors and driver transistors on it, and it turned the screen on. The only draw back is it won't completly turn off. I can tell because I don't hear the relay click when you first turn it on or off. When you flip the switch to auto it works but will not turn off. When you put the switch to normal it will not work but will turn off. Any answers?

    the tv was on. we could hear it all the way back to the other rooms so we didnt imagine it had a problem since tha audio was fine, but the screen is just black and the green button is stilll on.

Try Shining a bright light at the screen. can you see any images on the screen? If you can, then the backlight on the tv has gone, and can be replaced. If you cant then it may be a fault with the inverror (power) board on the TV
