Hi guys,
Got a bit of a strange problem. I was given a broken 1st gen iPad, and I reckoned I could put it back together and get it working.
It's been previously taken to bits, and is well out of warranty.
So, after I put it back together, the problem is this: the backlight is always on maximum. No matter what the auto-brightness or slider settings are. On one or two random occasions, the brightness control bar in settings has worked correctly for me and I've seen the screen get visibly dimmer or brighner... but the next day when I turn it on again, it's stopped working.
The brightness I'm seeing exceeds the maximum on the slider (from the one or two times it's worked correctly). The iPad gets really hot.
Then, after a while, the backlight will turn off. I can still see that the iPad is still responding to touch etc - it's just so dark you can barely see it. Turning it off and on again fixes it, but it doesn't last for very long unless you power off for a decent amount of time and let it cool down. Seems to me the problems are probably related, ie the backlight's too high, it's overheating and turning off.
The front panel is a little bit loose, so I thought maybe one of the cables was intermittently getting/losing contact. I've taken the front panel off and re-seated the three cables a couple of times, and it's still not working. For all the "teardown" videos etc on the web, nothing really explains what functions and signals each of these three cables has.
Also thought it could be a software bug/ I'm considering restoring it, but it seems unlikely to me as a potential problem, as the first thing I did on getting it was update it to the latest iOS via iTunes.
I'd like to fix it myself as I'm not keen on spending a lot of money to get it repaired, and I feel it's probably something simple.
Anyone seen this before? Or got any suggestions or useful sites they can recommend for further investigation?
Cheers,
GT
