LG plasma 26LC7D Power on cycle loop. Power light blinks green to red

[organizddisastr]

Hey all, I have a LG 26LC7D tv that has a power cycle issue. When plugged in the Tv will cycle on and off repeatedly. Screen will flicker and then shut off and on again. Its not responsive to anything. Just plug it in and it does this. I removed the back panel and there is a green led on the main board that blinks on and off with the power cycle. Then a red light that blinks on the other end of the main board. Any suggestions or info would be greatly appreciated. Thanks guys.

"LC" is not plasma, it's LCD. LG don't make 26" Plasmas... they did announce a 32" a while a go but the majority are 42" upwards.

Anyway, post a picture of the power supply board. This is the board that has a power connector on it, or where the leads from the power connector go. LG TVs of this generation have had huge problems with bad caps causing power cycling and stuck in standby problems.

None of the caps are swollen but I will gladly post a pic.

Have you got a digital multimeter?

So the TV will turn ON and OFF the minute you have it plugged into the outlet without activating to power switch?

That is correct.
