Those should help.

Having the exact Sanyo model can help you a great deal when searching for help.

You need to specify the TV model and chassis to get meaningful and useful help.

first just for trying--unplug set for a few minutes and plug it back to see if it resets.

If not someone will have to open set and check voltages on Power board to see if there or not.

There is another issue common if set 1-2 years old but that is the set at first has to be turned on several times to get it on--let me know if you had that one and I will still advise you.

I have the same tv and about 6 months after I bought it mine did the same thing. Its the motherboard. So I got it fixed and now it changes channels all by itself and jack the volume up randomly. I say junk it before you waste anymore money :(

P50HDM, loud pop then no pic...

its time to out it in shop and have it serviced. 1 of the modules caused the power supply to fail. that is why the grn. lite..

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.
