Mitsubishi television light turned on then two seconds later turns off

NOT A GOOD IDEA AT ALL!

You likely now have one of two things happening:

1. Green power light constantly blinks and will not stop(should blink for 70 seconds and go out).

2. Green power light comes on and a few seconds later goes off.

Which do you have?

check the lamp first to see if intact or shattered.

Provide correct model number but TRY:

when it shuts off, on the front of the set push both the menu and input buttons at the same time and hold them for at least 5 seconds and release both buttons.


Power light will blink a two digit error code like: 2 blinks, 2 blinks a pause and repeat it 4 more times.

Let me know error code and I will assist you.

hold the menu and input/device buttons for 5 seconds and it will blink you a 2 digit code
1-2 normal operation
2-3 i believe is short circuit protection = probably a convergence failure

Go to this post. I had the same problem and it was easy to fix...it cost about 26 bucks total and took about 20 minutes start to finish!

Good luck!

Replace both of your convergence ICs they are STKs big black ICs will have part number on them.

try unplugging your convergence board and see if it powers on my samsung had similar problem except red timer light,anywho i unplugged mine and it powered up

Your bulb could be in needing of being replaced

Let's just buy new TV's to help stimulate the economy.........
