Question about Sanyo Televison & Video
Need help fix this problem please it power on or two second and off over and over
Hey Chris, take off the back cover of the set and disconnect the key controller board. The key controller is the board that has your side buttons attached to it. If you replaced the main board and power supply with good parts, the only logical thing to try next is the key controller

Sorry bout the Live Session.
May I suggest something?
Pls try another signal source other than the indoor antenna such as a DVD or even an old VCR.
It is possible that what you are experiencing is video muting due to dirty antenna signal. If even with a stable known to be good video source (DVD) the problem persist, then it is a matter of checking the voltages as indicated in your service manual.
Hope this be of some help/idea even if the chat did not work out. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

I would check the soldering first for any cracks, and any obvious faulty capacitors or components. It looks like the power board is going into a protective mode because of a short / failed component somewhere.
It would be virtually impossible to guess exactly where with a spot check..

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.
The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

I would recommend Shopjimmy.com.
Parts are at reasonable prices. Compare with the prices at Partstore.com and you'll see what I mean.
