Not powering on or charge symbol


I dropped my Samsung A51 cracking the screen in bottom corner. The crack spread across so I decided to replace the screen. Bought a screen and shell assembly and new battery. Transferred motherboard, charging board and battery to new shell. Put back together and doesn’t power on nor am I getting the charging symbol. I have tried the hold buttons down power on thing, but still no joy. It does do a small vibrate. Then nothing. Any suggestions please.

Many thanks,

You probably messed up somewhere, try to just do it all again (take apart and put together) and hopefully you do it correctly and it works.


I've done that. It's making the same vibrate that occurred just after I cracked the screen. I've a new charging port and new screen.


I took it all apart again. Then connected the ribbon cable to the motherboard and the power board without it being in the frame. Then place it in the frame, connected battery and small screen connector. Turned it on….. and it turned on. Booted up. It works. 🥂🥂🥂

Thankyou everyone.


@tonybee76067 everybody makes mistakes and when dealing with tech like this mistakes aren't rare, when running into an issue like this you should immediatly jump to the thought that you did something wrong (no offense to your ability to fix something).

It sounds to me like the screen is not connected properly or worst case scenario the screen is damage. Well let's not jump to that yet. Check the main flex/ribbon is facing the correct direction. There's an arrow that should be pointing upward.
