TV Repair Questions? Ask a TV Technician for Answers ASAP
i have had it since 2007.
where is the set blinking button?
the TV is mounted. Per the TV manual it could be one of the following
p42h401; p50h401; p55h401; p42h4011; p50h4011; p55h4011
no. it does not blink
did not work. problem persist
Unfortunately there are no resets or adjustments that will fix this problem, and the click sound and the fact that it occured after a power outage is significant.
There are two possibilities as to what was damaged. The first, is the Power Supply Board, or more specifically the capacitors on this board will absorb the brunt of the surge, will explode or short internally causing the Power Supply to see a dead short and not supply the DC voltages to the other circuits in the set. The other culprit, is the Mainboard- which is the board that houses all of the Audio/Video jacks on the back of the TV. The shield on any of the RCA, HDMI or Antenna Inputs acts as a ground/drain for any voltage that travels down the ground of a cable connected to it and can short out this board. Because the Mainboard supplies the communication to the Power Supply to allow the set to turn on, either of them can be your problem. Voltage tests must be performed at the Power Supply Outputs to determine if IT or the Mainboard are causing your problem. The average cost for this type of repair is going to be between $250-$350 parts and labor depending on which is found at fault.
