Have TV Questions? Ask a TV Technician
Hello, My name is XXXXX XXXXX I will be glad to assist you.
Can you please get me the model number off the back of the TV?
Also, when the screen goes black, are there any blinking lights on the front of the TV?
Additionally, when the screen is black, do you still have sound?
If you press the MENU button using the TV remote, does the MENU screen pop up?
Thanks for the reply.
This indicates that the Mainboard on the set has failed. This is the board mounted directly to the rear panel that houses and routes all of the AV inputs in the TV.
