I HAVE A BLUE RIBBIN LOOKING SCREEN GOING ACROSS MY SCREEN

That is most likely caused by the ribbin cable coming loose or going bad at its connection

Your dlp chip needs replacing. It's a job to do but you can do it.

Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

need to replace stk392-110 price $300 - 400 for repair

bad optic unit block

That same thing happened to me. I disassembled the ps2 to find out the problem, I found out. If your console does not turn on or no lights check the silver ribbin connected to the reset button. See If it is in all the way the top and the bottom of the ribbin or check to see if there are any tares in it if there is replace it . You can get good parts off of Ebay.

What is the model number of your set?

I had the same problem with mine. I replaced the power supply and the problem was solved. That was about two months ago. Now I have the problem with a very brief blue screen, then going black with the sound still working. From what I have been able to find out it appears now that I have a bad power inverter. I will be replacing that next.

Does anyone have a problem with the screen looking cloudy? When my TV was working, I could see areas that looked like faint black clouds across the screen.

Those lines sound like "retrace lines" and several things can cause them. The most common are shorts inside the picture tube and shorted semiconductors in the video driver circuits. They can also be seen if the blue screen voltage is too high or if someone has tampered with the screen voltage control.
