My second hand (aka no Warranty) XBR-65A9F OLED goes into standby with a 3 blink fault. The 3 blink fault is either a power board or the mainboard failure. I’ve replaced both the mainboard and the power board. I know I’m supposed to do a software update on the mainboard, but I can’t get it powered on long enough to apply the update. Tv will boot to the Android boot screen then click off with the error code. I’m frustrated because I can’t get this thing up and running. Any help is appreciated. Here is a pic of the power board that I replaced; mainboard is below the power board.

@sioomagates isolate the other boards and let us know what you get. Just keep the mainboard and power board connected and let us know what and how many blinks you get. Disconnect the audio board/ speaker as well. Post some images of your boards and the interconnect cables with your question so we can see what you see. You also want to let us know if the new main and power board changed anything or if you had the identical errors before Adding images to an existing question
