Common TV Symptoms Fixed

Main-board faults may cause startup, input, audio, or control problems. These symptoms alone do not confirm a failed main board; diagnose the television before replacing parts.

Fitment & Ordering Guidelines

Verify the white-sticker part number, PCB/board number, full TV model suffix, and any version code against your original board. Match the sticker and version before ordering; model number alone is not enough to confirm fitment. No specific version code is supplied in this listing.

Unplug the television before service, use ESD precautions, and handle the board by its edges. Installation should be performed by a qualified technician.
