Question [Q] Arrrggh - The unit powers on but the screen $&?@#! won't turn on .

Phone was at about 70 % plugged in at the time.
I went to check on something and the screen wouldn't turn on. It vibrates when I hold down the power buttons.

Initially I thought it was corrupted somehow so I flashed it using adb, fastboot command. I think I've flashed it properly . I even did it again for the heck of it using wugfresh. I can see it on the PC as Nexus 5.

Now I realize that it's probably the screen. It was dropped in water a few months ago but it's been okay since I replaced the battery. I pull the battery and plugged it in, there was no white battery charging indicator.

Any suggestions ?

Thanks.

Disassemble phone to check morherboard and screen for corrosion. Try to clean the connection points if possible. Depending on the problem you may have to buy a new screen or motherboard or both.

Can you see the internal storage through your computer and manipulate files and whatnot?

One thing you can try that isn't intrusive is to try a Slimport adapter and seeing if you can get the screen to show on a TV/monitor. If you can, that pretty much confirms it's the screen, and you can proceed to do what the above post suggests.

I took it apart and noticed a tiny bit of corrosion through the magnifying glass and cleaned as best as I could.

I can see the internal storage. There's nothing on it because I did a stock re-install but I can see all the folders.

The Slimport adapter is a good idea to confirm if it's a screen issue. I'll look into it to see if it works just by plugging it in . If so, I'll grab one off e-flea.
