Check its speaker/s first. If found OK, check and replace damaged component/s at its audio output stage circuit. Keep an attention to the audio output IC. For more information go to http://electronicshelponline.blogspot.com/

Its either a bad power board or it could also be the main, but power supply boards are common failure on older sets, you could remove the back and see if you see bad capacitors and replace them instead of replacing the entire board for a couple bucks if your tech savvy.

When I turn my Sanyo DP37647 TV on the green light comes on but there is no picture or sound.


When there is neither picture nor sound you're likely in need of a service or replacement of the main board.

Service is usually the way to go as replacement is unable to find or too darn expensive, at least in the past year or so.

The typical indication of this problm is that the front light doesn't just stay green, but actually blinks for a second every 15-20 seconds.

If it does that you're definitely in for service.

The DP37647 model isn't listed there as we're planning to post about it in a separate article...however it has the same symptoms as some of the others.

If you want to send the board in for repair , shipping instructions can be found at http://www.coppelltvrepair.com .

It really isn't a simple DIY service like a fuse or capacitor replacement.

No picture, has sound


Please see my post on this set here:
Sanyo problems
This could be a series problem and I would suggest to any or all of you check with Sanyo to see if they are doing anything about making you whole again.

No sound coming from unit. Everthing is turned on.


locate audio output IC. GO to www.alldatasheet.com for the pin out. CHK for VCC, CHK on the INPUT on the ic for a small sound via an amplifierOR before forget rub your finger across ic pin to see if you hear a if you hear a sound then your problem is in the preamp stage and not the output.
