I have 2 LYNX II. One purchased new and the other from ebay, used and defective but I've restored to like new condition. The one I purchased new was great for a year and then those annoying vertical lines (Batman), color bleeding, and ghosting (transporter looking effect) started to become more pronounced. It progressively worsened to the point it made characters and hazards in a game unplayable. I found out about BestElectronics and purchased a new LCD, replaced it, and now it's as good as the first day I played it. I was first advised by BestElectronics to clean the contacts on the ribbon cable but there was no change. All the LYNX systems that I have played with over the years, both models, there is always some bit of the effects I mentioned above but to a much lesser degree. The LYNX II I mentioned above that I rebuilt appears to be getting worse. So it may need to be replaced soon. I think this time I'm going to purchase a couple to have a few on hand. I understand this is a primitive LCD, but does anyone know what it is that's causing this? Is playing it with low batteries possibly damaging to the LCD over time? Or is this just something that naturally happens over time with this type of older LCD?
