Sieg67 Posted May 22, 2018 Share Posted May 22, 2018 (edited) Probably not easy. For one it'll depend on how the tablet is put together. Like, can it be easily disassembled without destroying it? Next you have to have knowledge of the components responsible for the back light. You may be able to find a schematic online but you'll still have to know what you're looking at. The problem could be a fuse, a resister, capacitor or a chip that's responsible for back light communication. Or maybe you can get lucky and find some corrosion that's causing the issue. After identifying the problem, you'd have to remove the old part, replace said old part or maybe even run a wire if a trace went bad or a pad is gone. If it's like a phone, there may be some underfill under the chip and that's not something you want to mess with. With all that being said, I've never done any repairs on a tablet. Just throwing out possibilities. Edited May 22, 2018 by Sieg67 1 Link to comment Share on other sites More sharing options...
