My Mitsubishi 73" won't stay on blinks 3 red and 7 yellow
My Mitsubishi tv model WD73740 turns on for 30 seconds then shuts off and blinks three red then seven yellow. What does that code mean?
Is this a good question?

Linda Blubaum that is error code 37 which could be indicative of a failure of the DMD fan. You will want to check the DMD fan to be sure that it is clean and has nothing blocking it from rotating. If that looks ok consider changing the fan.
