Hi, the iPad mini I have to repair is a A1489. It was damaged on the back side. Looks like it was bent. The glass is intact but I think it’s the LCD that isn’t working properly. I may have to take it apart to make sure there are no other damages. When I was able to turn it on, a partial screen appeared with the appearance of shattered glass, with many colours.
Should I risk purchasing the LCD and digitizer? Thank you.

Have you tried to test signs of life like toggling the mute switch on/off? If the battery is not dead but the LCD won’t display anything, that doesn’t always mean that the iPad isn’t on. If you plug the iPad in for awhile (rule out dead battery) and if the vibrating motor on the mute switch still works, then toggle the mute switch on/off and you will be able to feel that vibration. If you want to diagnose even further, you can always open the iPad, unplug the LCD from its connector on the logic board, then proceed to use multimeter and measure that connector on the logic board. I personally do not know where to obtain the normal values measured from that connector other than a shematic, measuring the same but working iPad, or someone on here that has access to schematics and values and knows which points to measure.
这个答案有帮助吗？
Thank you for the information. I just added a picture of the screen I see after letting it charge for a bit.
Does the mute switch/vibration work?
I tried the mute button
I’m assuming it is the one with the red dot beside it? No vibrations, no noises.

i did spot a fracture or small cracks in the screen under the glass.

so I’m going to have to take it apart to check for further damages. I’m only an amateur at this, so using a tester is out of my league lol. I am able to replace things haha. And I am particularly good at disassembling things.
