The board is known for several typical failure points that require the schematic for precise diagnosis: Check your physical board for a white sticker

When you see "upd," it may refer to a of the board (e.g., TPV56PB801 Rev 1.0 vs Rev 2.0). Check your physical board for a white sticker reading "94V-0" and "REV:XX". Download the schematic matching that revision. Old revisions may have different resistor values on the LED current sense.

: It contains the boost converter IC, inductors, and MOSFETs necessary to regulate current so that the display maintains a consistent brightness without burning out the LEDs. 3. Main Processor & Memory Block (TSUMV56)
