65 inch TCL TV, Unfortunately not working , see details below

Good day I have a Roku TV that has stopped working. A power supply board has burnt out. The details are as follows:The TCL 65S423-CA is a 64.5- inch 4K UHD HDR LED Smart Roku TV featuring deep black levels, a 60Hz refresh rate, and direct LED backlighting. As a budget-friendly unit, it is highly rated for its built-in smart interface and sharp upscaling. I can send you pictures of the electronic board as well. Let me kindly know how much you would take that for. Original clear film still on the screen, so good condition tv considering the board issue.
