I have a TP.MS3463S.PB711 that is boot looping. Immediately you apply power the standby LED turns white but it doesn't start up. After about 30 seconds it goes red for a second and then back to white.
I have 40v for the backlight but no boost. Pin 8 (PWM) for the backlight boost is 137mV so it is off. DB101 is generating the 12v rail. The 5v rail is produced on LD1, the 3.3v is present on UL1 and the 1.2v is on LD2.
We appear to have all the power rails, no short on the backlight or anywhere else I have checked but she will not start up. Any ideas? Thanks.
