Getting power is one thing. Converting and distributing the power to the TV's internal components is another.

Were the power supply's output voltages, etc. tested?

Who replaced the main board?

If a shop take the TV back per the repair warranty.

Otherwise, if you did the work, you may be able to return the main board under warranty.

Could be a difficult case to make if the installer (you) was not certified to do such work.
