My out of warranty Mitsubishi LT-54422 is having a starting/turn on problem. When it doesn't start, the blue power light blinks.
Sometimes it starts right up fine. Other times I have to unplug and let it set 5min to several hours. Sometimes after unplugging, the blue light will blink for a long time and stop blinking, then it will start up with the power button. It has turned off when it was on a couple times
It was in storage for 2 years and has moved cross country in a Uhaul a couple times.
I also have noticed horizontal lines on both edges about a 1/2" from the edge of the screen of the screen that go away after a while. Not sure if its related.
I have tried with no luck:
unplugging all inputs
plugging it into wall, (its plugged into a Monster Power surge protector)
Closest TV repair is 100 miles away and only open M-F 9-5. I work during those hours so it would be about the cost of a new tv to make two 200 mi trips, take two days off work and gas (13 mpg).
Would like to try and fix it my self if I can figure out how to diagnose the problem.
