TV wont turn on no standby light

My Samsung TV won't turn on its actually the un55mu6300 no standby light I replaced the power board and the main board and it still won't power on. This happened after a thunderstorm power outage. Anyone? If not power board or main board what can it be. Also the backlight turns on when the main board is disconnected from powersupply

seangosner this”backlight turns on when the main board is disconnected from powersupply “ in general means the issue is the main board but since you already replaced both, I would suggest that you measure the voltage on the connector between your power board and the main board. Let’s see if this turns on since there may be a possibility of a bad P-function board. Take some good pictures of all of your boards and the interconnect wiring between them . that way we can see what you see and try to assist you further.

I personally doubt it that a lightning or thunderstorm could damage the TV screen/panel. If by disconnecting your power from main the backlight turns on, then you must be having problems with main board.

Now, you must order the exact replacement, you can not order a main board based on model number only. You must match the number that is printed on your board next to the barcode.

For example: we have lots of main boards in-stock for UN55MU6300 with part number BN94-12037A. If you board show this number please purchase from our site. Our boards are tested and are sold with warranty.

Hope you can fix your TV!
