The display has been flaky for a while flickering in and out and sometimes going completely out. Up until now when it went out completely, a good nudge or shake of the machine would get it back on. Now it won’t come on at all. I’ve tried reseating connectors and ribbon cables but haven’t had any luck. Are there any other areas to check that will tell me if the display is just bad? I’ve read that an outgassed display may have a white powdery residue under the glass but I don’t see that here. I’m pretty sure it’s the original so it very well could be dead but I’d still like to explore all options before buying a new one. Thanks!
