Easy fix for new Samsung TV switching on and off power cycling.... My tv turns on and off by itself the ...

Samsung 46" LCD TV (LNT4665F) turns off and on over again -

You are likely to have a module bad....part number BN94-00864A and if you take it out (unpluggs) you should inspect it for capacitors that may be domed or pooched up at the top. If so they should be replaced first before getting the module as the capacitors are about $1.00 each. Do a search for Samsung parts online if you need the module and call them toll free

It sounds that your TVs' timer function is set to 'ON' for 15 minutes time. Check it, and make it 'Off'. Refer its user manual for details.

I have samsung TV 40 inches flat screen comes on the picture ok but within 10 minutes the picture goes black and white

Clicking is from the power supply failing. Some capacitors are failing to hold voltage.

Samsung This link will take you to some articles that go indepth on the problem. also 1 of the articles is about a class action lawsuit in the works for this very issue. thx

It can be the backlight inverter board is bad, or it can be as bad as the lamps also, also check power supply section for bad capacitors.

There is a problem with the power supply in your TV. The regulator switch is causing teh clicking sound you hear. In order to fix it, you will need to replace the power supply. This is done by taking off the back cover of the TV, locating the power supply which is usually a yellow board that will have many high voltage capicators on it and replacing it with a new one.
