Device resets when a compressor kicks in nearby. Manual solution: Section A – Power supply requirements. The manual specifies a minimum 500 mA inrush capability and recommends a 100 µF electrolytic capacitor across the power terminals if long cable runs (>30m) are used.

The is a 4K "three-in-one" main board and power supply unit commonly used in various LED television brands, including RCA , Proscan , Avera , Haier , and Continental Edison . Because it integrates the main logic board, LED driver, and power supply into a single PCB, a "service manual" for this specific board typically consists of a schematic diagram and PCB layout rather than a traditional user guide.

Ensure the perimeter rubber gasket sits flush inside its channel before clamping the front and rear casings together to maintain the IP54 water resistance.

In many cases, the solution is to rewrite or replace the firmware. This is done by reprogramming the BIOS/SPI flash chip using a programmer like the CH341A. Dedicated websites host firmware files specifically for this board, which can be downloaded and written back to the chip to restore the TV to full functionality. This process, known as "flashing," is a more advanced repair technique but is a critical service for this hardware.
