Had the same issue (with the backlight cable, not the LCD) and came to the same solution, electrical tape and all. But even after securing the cable with tape, the connection still becomes loose and flickers on several occasions, so I have to reopen the tablet and reseat the cable. I think the clasp that holds the ribbon connector feels a little loose. Not happy about this. Now after having done this again (just last night), I am having wifi connectivity issues (shows a full connection, but nothing loads). Still searching the forums, but no luck so far...
