I am wondering about the rubber strips that power the LCD. Is there a particular orientation that they should slot in? The long edge on one side has a checkered pattern whereas the other side does not. Does it matter if the edge with the checkered pattern is facing the module or the LCD? Does it matter which strip goes at the top and which at the bottom of the LCD?
Background: Have replaced the LCD on my 1289 DW-6900 with a newer one from a special edition DW-6900MF-1. Installed new battery. LCD doesn't work apart from faintly displaying a couple of lines. When I removed the existing LCD, the strips were attached to it and I peeled them gently off. I cleaned them up with alcohol prior to reinstalling them. With the 1289 I could remove the LCD from the front, as the LCD is held in place by two metal brackets top and bottom which unscrew, so I didn't have to remove the white plastic assembly from the module and go in from behind like on other modules. There are no gold springs that I could see behind the LCD on this module. I believe the strips are the problem but can run a set of tests to determine what the exact cause is..
