Hi @niceguy12
Seems like a problem with the mainboard (supplier example only)
Was there a power outage or a storm just before the problem occurred?
If you decide to replace the mainboard then double check that the board number (printed on the board), matches what is shown in the link. Especially check what is shows on any stickers on your board as the board may be a "universal" board that can be used in a lot of TVs and it has been modified slightly to match the hardware in the Insignia TV.
There may also be other suppliers online that may suit you better. just search using the board information to find them.

hi @niceguy12,
Can you view the TV menu screens OK?
Please confirm the model number of the TV?
