The part number for the power supply, G board, is A1316475A. Sears does not have this board in stock anymore. The 5X blink code on your TV is an AKB error. The video is being blanked out and not necessarily a problem with the picture. The problem could be on 1 of 5 different boards. Each picture has a tube that could be causing the blanking video, the video process board, A board, or the power supply. I would recommend having a technician to diagnose the problem before buying board that might not fix the problem.

You can have it repaired at your home by a Sears technician. Here is a link for the website:
