Sony M5 screen with problem

[lmillert85]

Water got into my Sony M5. I took in an assist, and did the deoxidation.

It turns on normal, but the screen with the time of use begins to give problem and the lock (as pictured).

I took it again to the assistance, and they told me that the main board had been oxidized, and there was no repair.

I would like to know if there is any way to fix it (changing the LCD screen, touchscreen, etc.) or there is no way

I'm sorry to tell you this but if there are issues with the motherboard, replacing any other part won't solve the issue; to make things worst, the motherboard it's the most expensive part of a phone, replacing it will cost you almost the same as a new phone.
