Check the startup resistors supplying voltage to the primary PWM IC. If these resistors drift out of specifications, the IC cannot initiate the power-switching process. Fault 2: Stuck on Logo / Infinite Boot Loop
Press power on the remote. Check the BL_ON pin (Backlight On) tracking from the processor to the inverter section. It should transition from 0V to roughly 3.3V.
: Familiarize yourself with any industry standards or conventions that might apply. This can provide clues on how to interpret the designation and associated diagrams.
