S3 Won't Turn On

[StagnantSloth]

Hello,

I am having an issue with my S 3. It is not booting up as it should. The model is SGH-1747M.

I have tried the following and have had the following results:

1) The phone is non-responsive when attempting to power it on with the power button.

2) If I remove the battery, with the phone not plugged in, and then put the battery back in, the phone begins to power on by itself. It vibrates once and then loads to the Samsung screen and then goes off.

3) If I plug the phone in without the battery, the phone vibrates once and the red charging light comes on but then goes off after a couple seconds.

4) If I plug the phone in without the battery, and then insert the battery as soon as the red light comes on, the charging screen comes on but then the phone goes off after a couple seconds.

5) If I put the battery in with the phone unplugged and hold Volume Down, Power and the Home Button, the phone boots to the screen where you can push up on volume to flash new firmware. If I stay on this screen without pressing anything, the phone turns off after a couple seconds. If I push up on the power button, it goes to the screen with the green android man but then turns off after a couple seconds.

6) If I put the battery in with the phone unplugged and hole Volume Up, Power and Home and then release them on the Samsung screen, blue writing pops up in the top left corner (I couldn’t read quick enough what it says) while still on the Samsung screen and then it loads to a screen saying Samsung Galaxy S3 and then the phone turns off.

These problems started when I attempted to connect my phone to my laptop to transfer songs over to it. I connected the phone and the battery was charging, but it wasn’t showing up as connected on my laptop. So, I turned the phone off to restart it but when I went to turn it back on, these issues started.

The phone was rooted and has been for the last 7 months without any changes to the firmware or updates to the firmware in that time period and has not encountered any problems prior. I’m not sure what firmware the phone was on prior to this.

I’ve also tested it with another charger and battery. The same above symptoms occurred.

If anyone could offer any assistance with this it would be greatly appreciated.

Thank you in advance.

Welcome to the forums. Try this: take the battery out and on a flat, smooth surface, try to spin it. If it does, it is bulged and needs to be replaced. If it is bulged what is happening is the bulge in the center of the battery is causing a disconnection.

Thank you for your fast response. The battery does not exhibit the issue that you described. I've also tested a battery from another phone and the same symptoms described in my post occurred.

Perhaps a stuck power button?

Would this account for the phone turning off all the time at the Samsung logo? And would it account for the red charge light not staying on?

Thank you for your response.

I am honestly not sure. Just guessing. It might even be a bad motherboard.

Well, if it's not the battery/charger my next thoughts were also the possibility of a hardware fault (as GolfDriver was guessing, the possibility of a stuck power button or a bad motherboard)

OP - any chance you have a microSD card in your phone? If you do - remove it when the phone is powered off, and see if that changes anything. It's likely NOT the problem, but worth a shot - Samsung and microSD cards tend to not play nicely in the long run, and the S3 seemed especially bad for it.

As for the possibly stuck power button - if it was mine I'd attempt to unstick it with a pin, and carefully see if I could gently pry it outwards slightly. Please don't take that as a recommended course of action - but I'd try it, especially considering that it would be difficult to make the situation worse.

Any thoughts GolfDriver97?

The SD Card idea is plausible. Right now, anything simple and easy in attempt to diagnose is worth trying.

Update: The issue was with the power button.

Thank you.
