If you have the led light on, then you need to replace the mainboard.

If no led light then replace the powerboard.

Please check whether the connections are secured between the TV and the connected devices.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

Try connecting the TV to a different wall outlet and check if that helps.

Please connect a different device to the TV and check whether the issue persists.

If the issue still persists service of the TV is determined.

There is a problem with the processor. The only way to resolve this issue is to replace the main board. It is called the A board in your TV.

There are two for this model and the correct one will depend on what your serial number is.

Part numbers are as follows:
part # 185709211 for Serial #
1,000,001 - 1,350,000
1,700,001 - 1,750,000
1,800,001 - 1,804,270
1,804,271 - 1,818,372
1,818,373 - 1,830,000
list price: $504.87 core charge: $680.00

part # 185709231 for all other serial numbers
list price: $505.87 core charge: $600.00
