Question about Sanyo DP42746 42 in. Plasma Television
Once the Green light comes on, blinks then turn off after few seconds and there's no picture or sound, then you've got a defective power supply unit.
They also called it the Main Logic Control Board. Please check the link below so that you could see the picture and price of the board:
Good luck and have a great day ahead!

I Suspect Power Supply Board.Open the TV and look for Power Supply Board. Once you find the Board, Pull out the Connectors. Take the Board out. With the help of magnifying glass, you need to check Cold Solder Joints.If not, then Check the Caps and Fuses. I imagine, if this could be due to Power Shut Off, you would be able to Find Some Bulged / Swelled / Leaked Caps. You would smell Ammonia kind of odor. You need to pull them out. Order the same Caps online or go to Radio Shack. It would cost you few bucks, in fact less than 20 bucks. Once you get the Caps, solder them and it is all set.
Note - You need to take all the Precautions as this would involve Voltage.
Let me know, if problem persists so that we could further troubleshoot.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
