Power & picture keep going off with red power button blinking

Hi @don56, Check if the red power button LED is blinking an error code. It will blink in a pattern that is repeated 5 times e.g. a 34 error code is 3 blinks > pause > 4 blinks > pause > 3 blinks > pause > 4 blinks > pause etc. Here’s an image showing the meaning of the error codes for some Mitsubishi TVs. Hopefully your model is included. The model numbers are at the top of the page in the image.
