ZIP archive for the TP.RD8503.PB819 universal LED TV main board, with firmware set for a 1366×768 panel resolution. Boards with the TP prefix are generic Chinese-made units fitted to many budget televisions, and the PB code typically designates the board variant. Contents are most likely an SPI flash dump configured for HD-ready panels. Flash it with a programmer when the board shows wrong resolution, mirrored picture or fails to boot. Verify the board marking and panel resolution first and back up the original dump.
