I have been using my Sanyo for about 9 months or so and have been happy with it. When I first set it up..I had the same problems as most with Vertical Banding. I used some adjustments found here and it worked good, they were for version 1.03 and I have a 1.06 version. The problem is, I took the projector down last week to clean out the dreaded DUST BLOBS..( from instructions I received here ) and when I set it back up, I went through the service and factory menus to see if the settings stayed in after unplugging it and I think I might of changed a setting, by mistake other than the ones I have received from here. It seems that Screen door effect is very noticeable now when it wasn't before. I am not getting any other problems than that. Does anyone have tweak settings for Version 1.06 that you could pass to me? I would need all the values...even the ones you don't usually change from the factory. Or does anyone know how to put it back to default settings so I can start over. I did record my factory settings for the numbers I did change ...but not for all the other numbers. Please help if you can.
