Acer h7530d wierd issue with vertical lines

Hello this is my first post and it is a stumper for me. I have an Acer h7530d projector that is getting vertical lines around bright images. The lines are evenly spaced. They are also in the menu with nothing attached to it but are more like dashes. The vertical lines are evenly spaced dashes when watching a move around high contrast areas. When in service mode in the test pattern menu I have scrolled through all the patterns and colors. All colors are fine execpt bright white that has the same vertical lines evenly spaced. The vertcal lines on the test pattern line up with all the dashes and vertical lines on any menu or movie when watching. Also you can see the entire lines from top to bottom on that bright white color in the test pattern mode. Dont know what it can be any info would be great thank you

Its not under warranty. I tried to talk to an acer rep but they wouldn't help me cause of no warranty. Acer website is awful there is no helpful information on it for this model.

Hey just wanted to let you know it was the light tunnel and dmd chip were bad. I sent to royalcameras.com and they fixed it for $335 with next day shipping. It is working great like new again Still cheaper than buying a new one that would have cost $1100.
