Why is only bottom 1/4 of LCD working after screen replacement
My Ipad air first generation got smashed including the back case bent and I was told it couldnt be repaired to insurance paid out for a new one but left me with the old one so I thought I would see what I could do with it.
I bought a new rear case and managed to strip everything out of the old case and install in the new (even managed to get the batteries out without even bending them). powered it on with no lcd or digitise and it connects to my PC, makes the right noises and also is connected to my wifi so looks like it could be working order.
I went to the next step and bought an LCD from ebay and connected it up. When it cold boots the apple logo appears in the middle of the LCD but then when the swipe screen appears only about the bottom 1/4 shows. The rest is black. I have tried disconnecting the battery for a while a trying again and same thing. Sometimes the top of the screen is there briedly but then disappears.
Does anyone have any suggestions. The LCD connector on the board looks OK - no damaage. COuld the issue be the screen? I have contacted the vendor about it who suggested that it was caused by wrong installation but them offered me 40% refund, upped to 70% when I went back. I havent accepted anything yet. The suggestion that it is bad installation sound like he is fobbing me off as it is only one connector involved. Also, the fact that he is quick to offer me a partial refund and I keep the screen suggests that he wants me to settle so he doesnt have to give full refund. if it is true that I have damaged it then he wouldnt have to give me anything.
Anyway, anyone have any suggestions on what I should look at?
As an aside, I also bought a new digitiser which I connected up but doesn't seem to work at elast on the bit of the LCD which is working. I havent removed any screen covers etc for that. SHould it would before it is installed against the LCD?
Is this a good question?
