iPad 7 with a serious short in backlight. Right after I changed these components, the iPad started SMOKING! You can see the burns. But all is not a big deal. I found the short & fixed the iPad. Found out it uses the same boosting IC as the iPad 12.9, all done with out schematics & only possible for a person with a decade of experience to see the issue & fix it affectively. Proof is in the pudding.
