I've got a Sony 1252Q that has starting some weird scan line issues.
My rig is as follows: PC/Xbox-->Yamaha 765-->Hdmi to DVI cable-->HDfury-->1252. Everything is converted to 1080i by the Yamaha before output. Running roughly an 85" screen at 16:9.
While playing Halo tonight, I noticed that at the very top of the picture there would be a single (maybe two) scan line of green that would flicker on an off. Very intermittent. but was consistently so. Over the course of about 2hrs, it got much worse. It went from just a few scan lines flickering, to those lines jumping down a good 6-8" from the top of the picture. They flicker and jump lines at random, not related to noise/vibrations or what is on the screen.
The projector has always had some alignment issues, the leftmost part of the screen has a ripple all the way down the picture that I was never able to converge out. About two years ago I adjusted G2 voltages that were waay out of spec, but honestly have been to lazy to check them in recent months. Other than that I haven't done any internal tinkering other than blowing out with air.
I'm hoping this is something someone has seen before, with a possible fix. I am about to remodel a basement room into a proper theater space, and was hoping to squeeze some more life out of this trooper. CRTs are hard to come by around my area. Other than a few quarks, thing has been fantastic for what it is, and it's age.
Any thoughts are appreciated. Thanks!
