Sanyo tv model DP15647 sound but no picture.
The tv screen is black. No static picture at all, just black. The tv turns on , has sound.
Any suggestions? I like to tinker.
it's not likely that you need to replace the LCD unless you have dropped it or have obvious signs of damage to it, it is more likely that the power supply to the LCD is the problem. Most modern TV's have a power board, sound board and for want of a better term a picture board. The picture board on some TV's have capacitors that are prone to going bad..just replaced them on a cheap BUSH..cost £1.79. Unfortunately it's not always that simple.If you have sound when you play dvd or select TV mode then the likely culprit is a part on the picture board. If you are confident then you may like to try taking the old board out and putting in a new one. We may get lucky and oldturkey03 has the service manual to help you out in doing that. (I didn't have any manuals to go by but the nice people who made the TV put arrows on all the screws to remove for the back and disconnecting connections between the 3 boards was relatively easy, most were push pin connections-no soldering etc involved. All I needed was a philips head screwdriver and some patience) You can find the part no. you will need written on the board itself, and parts are pretty common on ebay. Good luck.
Although most of these posts are old one solution I found and worked for me was resetting my digital box, just unplug your cable box and plug it back in a minute or two later.
