Schematic: Tp.ms6486t.pb753
First, I should confirm what TP.MS6486T is. Maybe it's a touch panel module or a type of IC. Let me check online if I can find any information on TP.MS6486T. Oh, found a manufacturer's website mentioning that it's a touch panel controller for capacitive touchscreens. So, it's probably an IC used in devices to handle touch input. The PB753 might be a specific circuit or application using this controller.
These issues are frequently software-related and may require a firmware reflash via the USB port or directly to the NAND flash using a programmer. Local Availability (India-focused) Model 43PL VU LED TV Motherboard TP MS6486T PB753 tp.ms6486t.pb753 schematic
