This is djb1 who commented above on the vertical lines that have gotten progessively worse. I may have found a potential solution. I unplugged the TV, took the back door off where you replace the lamp, took the lamp out, changed our vacuum from a vacuum to a powerful blower and blew ALL visable dust off anywhere that I could. I paid special attention to the heavy dust that was on the TV blower fan blades and around the mirror. I also held the blower on the outside of the TV on the vents around the lamp door.
After I plugged the TV back in, the lines have disappeared. We watched TV last night for about 2 more hours and the vertical lines never came back. So far this morning, the lines have not come back and it has been a couple hours as well.
It's worth a try. The free solution may be as simple as clearing out all dust. LET'S HOPE IT'S A PERMANENT SOLUTION!!

all 3 lights blinking means lamp has a fault the service manual says replace the lamp. If you need the service training manual for that model let me know and I will post the link as the training manual has excellent trouble shooting breakdowns for that model DLP

I did some reading on this. They said its caused by a faulty DMD board. I understand it's costly... around $700 to replace. Still looking for a cheaper avenue...

Cleaning th mirror and lense will remove the haze. This oldel is much older that 2 years though.
