Hi @renegadesoffun ,
Just verifying that if the power board is a BN44-00807K and that when the power is connected to the TV with everything connected that there is 11.8V on the Standbypower test point, (see image) is this correct?
(click on image to enlarge for better viewing).
If so then this voltage is what is used by the mainboard to turn the Standby Power LED on .i.e. the mainboard turns the LED on/off. It is not turned on directly from the power board.
Try the following:
Disconnect the power from the TV and then disconnect the cable between the mainboard and the power board at the power board.
Reconnect the power to the TV.
The TV backlights should turn full on intensity and stay on. There will be no picture because the mainboard has been disconnected.
When the mainboard is disconnected and the power is applied to the TV the power board is turned on to full power output because the signal from the mainboard that keeps the power board in standby mode, until told otherwise has been removed.
You can then check the voltages from the power board to see if they are OK knowing that the mainboard is not causing any interference with the power board.
Just trying to eliminate where the problem may be.

Thank you @jayeff for your insight! Yeah i couldnt quite find out where on the power board the clicking was coming from but since it was an overvoltage and the circuit breaker did not open im guessing it just fried this part? So yeah Im prob gonna go ahead with you and say its the power board and just buy a new one to replace it and hope it works! Thank you for your help!!!!
