Question about Sanyo DP37647 37 in. LCD TV
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.
