If power light comes on and then goes off do the self check this set has:

when light goes off and front of set press and hold both the menu and Input (device) buttons in at same time for at least five seconds and release both buttons.

The set will (the power light) blink a two digit error code like, 2 blinks, 2 blinks, a pause and repeat the code several times.

2,2 is most common error code, let me know what error code if any you find and comment here and I will tell you what it means.

The self check is designed to narrow down where a problem is.

if you unplugged it you will only get the no error code 1,2.

Plug back and turn on, when light on power goes out try it again--if power light goes out there will be a error code.

Do the self check when power light goes off.

On front of set press and hold both the menu and input buttons for 5 seconds or longer and release both buttons.

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

Let me know what error code you find and I will tell you what it means.

If this information told you something rate this solution as very helpful as I do this here for free.

In your On Screen Display menu (OSD), you should have a place that says "convergence". As a sub heading to this it will say "Auto-Convergence". This is where you want to be! Hit OK under AUTO, and watch the magic happen! If your set happens NOT to have AUTO, you'll have to do it manually. You're going to make the lines all match up doing one color at a time until all three colors are done! It's not hard at all. It may take a little patience at first, but just think of all the money your saving by not having a TV tech come out to your house and you'll be fine!

your convergence circuit has started giving trouble .... normal thing after a few years running for projection televisions ...... could be that the convergence IC's are getting too hot (two big IC's on a heast sink bearing an STK number on it) or that you have some loose soldering that needs to be resoldered on them.... worth the check

Good Day;

The fuses tell you that circuit has failed and was drawing too much current. No other test is needed.

Good Luck, big Irish.

It s a Power supply problem.If you are not familiar with electronic repairs take it to an authorized repair shop.
