I have Panasonic (TH50PV600M) TH50PX600U, The TV won`t start, when power on I get red lights blinking (one time) and then followed by green lights blinking (three time) then the TV just shuts down and start again to do the same sequence in a loop, which board do I need to replace?

Try unplugging the power from the TV, then press the power button at the TV for about 30seconds. After that, try powering on

Did you try this (from another forum):
switching off the TV for 1 minute (at the TV). Then on the side of the TV, holding the down arrow button and pushing and holding the on/off switch until the TV light blinks green, keep holding it until the TV comes on. This was about 30 seconds

Thanks for your feed back, I have already tried all these tips many times with no luck at all :(

What's killing me, the TV not showing any red blinking code to determine the board that causing the problem.

Thank you helpstar for the great support, I am not sure what board is causing this issue since (I am NOT getting any error code), so I have placed an order for the d-board hoping that would be the salvation for this dilemma.

Here is the video ,,,, as you can see I get red lights blinking (one time) and then followed by green lights blinking (three time) then the TV just shuts down and start again to do the same sequence in a loop, NO picture or anything at all.
