Exactly my intention. Cleaning the screen ribbon connector did not make any improvement. Having a problem now opening up the non-LM 1440. Where I found size 5 torx screws in the LM 1440, the same size torx bit screwdriver slips in the head of the non-LM 1440 screws while size 6 does not fit. Yet, with a magnifying glass the screws definitely appear to be torx type. Ordered another miniature screwdriver set online with a variety of sizes and shapes (flat, allen, torx, phillips, pozdriv). Will only arrive on Tuesday. To be continued...
