Xiaomi mi 8 screen black out still after changing motherboard
Hi. My phone is water resistant. Put underwater for 5mins and the screen suddenly blackout (charging and power on is working normally). 2hrs later, I disassemble everything and clean with wet and dry cloth and assemble back. Screen still black, went to phone shop and they recommend to change motherboard. I change it myself (order from online) but the black screen still happen except everything still operate normally like before. Is there any advance ways to repair? Thanks
Is this a good question?
