Galaxy Screen Off Not Waking Up Again

April 23, 2022 Post a Comment

Hi,
My screen was croaky and I have replaced with an original A50 screen. When I turned it on the phone booted correctly and worked fine but when it went to sleep subsequently 30 seconds (default time) of inactivity it will not wake-up even subsequently pressing power key or tapping the screen (motion and gesture settings are right) simply the phone was internally working. When some i call the phone it rings but screen does not calorie-free-up (information technology does not wake-up) and I cannot pickup the phone.

The just way to restart the device is to press volume down + power key (soft reset). I likewise tied to mill reset and too flashed the phone only did not solve the problem. The volume keys works if audio or video is playing. The power key also works as information technology puts the phone to sleep style subsequently pressing it.

The only thing is non popping upwards is the ringer book popular-upward (slider) when I printing book upward or down key to reduce or increase the ringer volume from home screen.

Delight assist.

Thanks in accelerate.

The screen only comes on when you initially power on the phone. If the screen times out or you put information technology to sleep with the ability button it will not low-cal once more. It seems to function correctly when it is awake....

Power on the device and with the screen awake press and hold the power button until the power off/aeroplane style/restart buttons appear. Note where they are on the screen, I'd say aim for the restart button. Put the screen to sleep. Press and hold the ability push long plenty that those buttons would appear and press in the surface area of the restart button. Y'all may take to press twice, on my device I take to confirm that I desire it to restart. Then encounter if it restarts. This would ostend that the screen is actually working.

I take a feeling the screen is awake and the backlight isn't coming on. Without the backlight the screen volition appear night plenty that you really can't read or run into anything on the screen. Y'all could effort without restarting it to smooth a light on the screen at an angle merely I'thou not sure if that would work.

If the backlight isn't coming on it could be an issue with the light sensor or a defective screen. Granted it is an OEM part only it was probable from a damaged unit and their test before selling information technology was simply to see if information technology turns on, which it does simply that doesn't make it a proficient part. If yous're able to confirm that it is the backlight you may have grounds for a return or exchange. If the screen wasn't interim ordinarily when it was on, I might think that one of the connections wasn't properly plugged in, or wasn't fully engaged, only everything works when it's lit. That seems to point to a defective part.

I reassembled and tried what VidJunky suggested but no change. And then, the screen seems to exist okay. Next day, I have opened it over again and to double check on everything but no luck so I gave up and assembled it back even so same effect. I also took information technology to a shop and they checked on everything and said that they take not seen such an issue and cannot gear up.

Side by side forenoon it was on the table and I moved it to make some room and noticed the screen lit up and information technology stated working... I have no idea why.
