I was an apple tech for a time. With iPads that were out of warranty (basically go buy a new one or GTFO) and exhibiting a certain display issue, I would take it in the back and slam the thing on a counter at a certain angle. Worked every time for that particular problem.
why and how did that work, how hard were you slamming it, I am presuming not hard enough to break glass, but than, what would such a slam do? I am going to presume these were LCDs, and maybe the the liquid crystals would have gone too cold, and maybe by smacking, you somehow freed them or something. I would like to know more.
I had a similar thing on an old crt monitor. The screen would start to flicker badly after a while, and 8 year old me found if you banged the side, just right, it would keep working for a couple of hours.
Turns out the circuit board had some dry solders on it and when I hit it on the side where the board was, it got the connection back for a while.
Pretty sure it was a loose cable. They're basically giant iPhones and I saw similar issues on those. I should also mention said counter had an antistatic mat on it to soften the blow.
