How much is power supply board for TCL 50p637

Hi @sammykuhaman,

What is the model number of the power board (usually it is on a sticker on the board)?

Asking as even though the TV model number might be the same it may use a different power board depending on the location that it was intended for i.e. where it was sold, due to differing mains voltage supplies used in different countries.

Best option for you is to search online using the power board model number to find suppliers that suit you as anyone else would be providing information for their location and possibly not yours.
