It could be as simple as dust contamination in the LE or lcd chip. You need a clean room to work on this area of the unit and NOTHING you can do there would make that possible, short of spending a few thousand to build one. Before we added a clean room enviroment we simply pulled the LE and sent it in to PTS - who has one and reinstalled...
In your case take it to a qualified shop and you'll save yourself a lot of grief..

This sounds like the Sony blue star failure and this problem is under Sony extended warranty. Call Sony with your model # and serial # and tell them them you have the blue star issue and they will refer you to an authorized Sony service center and the repair will be free.

Cannon 6035 - no immage on copy pages


Are you getting a totally blank copy or just very light. If I were you I would cheak to see that the developer Lock is in the right place. It seats right under the developping unit. It should be locked to the Left. It will move the developing unit closer to the Drum unit..Good Luck

Hi. i have an LG 42inch plasma, approx 18 months old. about 2 months ago, a green stripe developed down the right hand side of the screen, approx 1.5 inches wide. last week a 2nd stripe the same width...


Sadly, the plasma screen is failing. The green strip is no longer functioning properly and the failures will continue to progress.

If still under warranty, get it exchanged.

Dark Vertical Stripe on Right Edge of Screen


I experienced the same approx. 1/2" vertical stripe on a Viewsonic vx1945 and ATI Radeon x1050 video adapter on Vista Business SP1, but the stripe appeared along the left edge of the screen, instead of right edge. I then temporarily decreased the monitor resolution, and the stripe went away. I then increased the monitor resolution back to its original setting, and the stripe did not re-appear. So, that was the 'fix' in my situation, hope this helps.
