Facing TV Problems? Ask a TV Technician.
Hello, I need you to check and get the full model number off of the back of the TV.
Also, the flashing can be caused by the "Source" (meaning your HDMI cable, Cable Box, etc.) as much as it can by the TV itself. So that being said, I need you to grab the original Toshiba remote and press MENU, and let me know if the set's own MENU flashes as well. Please reply back and we can proceed.
Okay, reply back at anytime and I will postback when able.
