Knowing NOTHING about the unit you are working on... two things pop in my mind from my TV/VCR repair days. 1: Is it possible the controller on the back of the tube is loose? When you tilt the lid (and from what I gather, the tube with it) back into place, maybe the board is shifting from the change in weight position. 2: Is there a cable or wire that is getting pulled on when you close the lid? Maybe one of them has a bad solder joint, and the joint stays properly closed when the lid is open, but when closed, gets pulled (or pushed), and breaks the connection. Have you tried, while the unit is open, to jiggle any wires that might be effected (obviously, don't do them with your hands, use a non conductive spudger or similar tool... wouldn't want you to kill yourself by grabbing the wrong wire) Again, I know NOTHING about the unit you are working on, so these were just shots in the dark thinking maybe something will help. -chris <http://www.mythtech.net>
