Relativity easy to do yourself, but better if you have some one to help, all you need is a Philips head screwdriver, and the replacement screens, the technical name for them are Lenticular Screen, and Fresnel, one is white, and the other is black.

You start by taking off the screws in the back of the the TV, there are screws along the top, both sides, and there are two on the the bottom right, and two on the bottom left, and there are three on the front by the power and channel and volume buttons. then grab one side and have your partner grab the other, and pull straight off.

IMPORTANT!!!!! DO NOT TOUCH THE WHITE SCREEN WITH YOUR BARE HANDS, IT IS COVERED WITH A POWDER AND CANNOT COME INTO CONTACT WITH ANY FLUIDS, INCLUDING THE OIL ON YOUR HANDS!

There are four bars that hold the screens in, one on top, bottom left and right. to remove the top, left and right you have to wiggle them loose after removing the screws.

The Black screen will go in first, make sure that the smooth side is what you will be looking at when you are done, the white screen will go right on top of it, the rough side of the white screen will meet with the rough side of the black screen.

then put the screen assembly back on, and replace screws.

I hope this helps, if you have any questions, let me know.

I'm sorry, but your looking at an Optical Block Assembly which also includes the DM module. Latest figures are approximately $650.00 to replace. I would have called a service tech out to properly diagnose the problem first. Please let me know if you have any other questions.

this sounds like a possible light engine failure

Hi,
Is that replaced lamp Mitsubishi original or any low price bulb?
Take out lamp, check is it OK and put it back in tv, make sure lamp cover is fixed properly after lamp re-installation.
Let me know if problem still not solved.
Thanks.

I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV(warranty was expired ofcourse) and found four bulged capacitors. Many electronic companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices. Here are some options . 1. 1.Have it fixed by a professional 2.
2.Dig into your TV, find PSB, Check for faultycaps. If you find some(bulged orleaking) bad caps replace the entire board 3. 3.Remove and then replace individual faultycaps. This takes some solderingskill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds. Hope this helps

Replace the lamp.

If you are using component cables (red-green-blue) for your cable hook-up you may have problems with the red one. Check to make sure it is inserted properly at both ends. Note that there is also a red-white pair for sound. This is not the red one in question.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it.
