@hm6gmpblupuy6u7 your Hisense is possibly not receiving the voltage drop from the backlight LED's and thus gives you the 10-blink error code. I would suggest getting an inexpensive LED backlight test and check the backlight LED's. Let us know the exact model for your Hisense. I assume you replaced the main and power board.
