    Oh ok well I'm now where the tv turns on for about 30 mins and then turns off all on its own it will shut off for about ten mins the capacitors are not blow or buldging I would think that would be the only reason for the board to be replaced

That sounds a lot like a power board or fuse error. Try replacing the fuse if there is one. Replace the power board if their isnt. Make sure that it is plugged into an UL approved surge suppresion or protection strip.

    I do not see a fuse, and a power board?

    I would recommend taking it to a qualified service tech. The power board is not a user serviceable part, and will need to be replaced as a whole to either fix the tv or diagnose further issues.

    Well the capacitors are not the only thing that can go wrong with powerboard, their are other componets to it that could fail, as well as the flow of the soldier and the quality of the soldier on the board. That is why I recommend replacing it as a whole, that way you dont damage other board(s)

Tv shuts off spontaneously. red power light blinks.

re: sony flat panel lcd tv mod. # klv s 40a10.
No power. When power button is pressed, nothing happens.
The stand-by at the power supply ( cn6201) measures to be 3.47 v. instead of 5 v. However, when I unplug cn6201 (5 pin connector) I can read 5v. at the power supply.
Any suggestions?
