Screen not showing an image when coming back from sleep?

VZW TP with Mighty ROM 6.
Hey guys, I started experiencing this weird problem yesterday. Basically, when the phone is turned on from sleep mode, whether I pushed the button to turn it back on, I get a phone call or text message, whatever...it doesn't show an image on the screen. I can see the screen itself light up (backlight or whatnot), but nothing else. Just a blank, black screen. It happens randomly. I've found that if I hold down the enter key on the d-pad, and turn the phone on, it works fine again.
Any clues, suggestions, advice?

You may want to try a program such as S2U2 and see if your phone will wake correctly.

Phone turns off while on call

Hi guys,
When I make a phone call, the display/screen turns off in a flash and i am unable to bring it back. I press all the buttons home,back,power key but only the button light glows but there is no response in the screen. Only if the call is ended by the opposite end i am able to get back to the phone.
Note : I had just replaced my touch screen glass yesterday ( Not the LCD ). Does this have something to do with this issue ? Or if there is any other solution please clarify my problem immediately.

Moto G Stuck power button

Hey everybody. I was looking the old threads, trying to find a solution to my problem but i didn't find anything.
I believe my power button is stuck!
The Moto G keeps turning on, and on, and on, and always takes the same time to turn itself off.
The screen keeps turning on, and then it freezes on the Motorola white screen, and then vibrates and turn itself off after 4 secs.
The same happens on recovery, after 4secs it turn itself off and then turn on again in the white screen.
When the problem started i thought it was a kind of soft brick then i've did everything i could to try to fix it reinstaling some software, then I noticed the time to turn it of/restart was equal on the normal boot or in the recovery. I realized that I could open the cellphone and when I connect the battery without pressing the power button he keeps ON when i'm in the recovery, then I flashed a ROM to make sure it wasnt a softbrick and now i'm concerned that somehow my power button is stuck.
Does anyone know what can I do to fix it? :/
Thanks,
Sorry for my poor English, it's easier when reading, but its really hard writing.
