    I've turned it off and on and unplugged the cords. Do you mean it it my wall outlet that is bad?

    While always possible this is sooo definitely not the common cause of the problem in those TVs!

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.

How do i turn the sound on my sanyo dp37647 off


As nearly as I can determine from your description, you want to turn off the Sanyo TV speakers and direct its audio to the soundbar. Your initial setup procedure should provide an option for doing this. If not, there may be an audio control button on your Sanyo remote that will accomplish this.

Sound but no picture


You could have a back light problem, or a video feed problem. I would suggest turning on the set and shine a bright light on the screen. Do you see faint video?

Sanyo dp37819 i turn it on green light comes on but no picture or sound and green light goes on and off


You can send your main board to us and we can give it a try.

If it the front LED turns on for a while, then off for 1-2 seconds and then back on...we'll probably be able to help.

See http://www.coppelltvrepair.com for details and shipping instructions.

Sounds like you just need to change your display mode, look on the remote for a button that says zoom, also in your display menu with your remote, there also should be a setting that allows you to switch from standard widescreen etc. choose full screed or wide screen mode that should get you back to full screen, please keep me posted I would be glad to Trouble shoot this issue until resolved.
