Hi everybody, sorry for my bad English. I bought on ebay this phone lg g7 thinq . The seller told me, he dropped this phone on the ground and then screen not working. When the phone arrived I see the screen and touch is not broken. The phone work but screen not. I tried to connect on my PC Everything is fine, the PC recognized phone. I opened and I see this connector between USB bord and motherboard is little bit Corrosion. I cleaned it with alcohol and brush. Now I don't now where is the problem, if I buy new screen and then not working. I don't know what to do in this complicated situation. Please help me

Re: Lg g7 thinq black screen

Welcome to Android Central! The only thing you can do is try to replace the screen (or have a repair shop do it for you). If that works, great. If it doesn't, then it may have more to do with the motherboard, in which case the cost of repair of this phone will probably exceed its actual value.
