My tv developed a problem where it will power on and the shut down. Once shut down it blinks red 4 times. It will power back on and then does the same thing. I have replaced the bmks board and ld board. Any insight as to what is going on? Also if anyone has the capacitor layout for the bmks board that would be helpful. The service manual has two listed but i cannot find a diagram.
@jamesla the 4 blink code is an LED driver failure/LED voltage protection [LD_ERR] Error detection of the I2C communication between the Main device and the LD IC. Most common failure is the LD board or the actual backlight strips. Follow the flowchart to determine if it is the LD board or the BMKS board.
. Post some good pictures of your BMKS board with your question so that we can try and help you with those caps. Adding images to an existing question
