Now it won't power on. Is this normal, or did I definitely damage the motherboard?
Hello,
Is it vibrating when turned on via the power button or connected to the charger? If so, the motherboard is fine.

Okay, so I have a Photon Q 4G LTE and for a while, my phone's screen would flicker and die sometimes. Then it eventually just went dead and the backlight still comes on, but it's a blank/black screen. I replaced the LCD and I'm still having the same problem, so I'm kinda stumped on what it could be. Any suggestions? Ideas or thoughts?
It could be a chip for display or flex cable. It could be also power chip not working well, having faulty power to the lcd.
Hi guys, I picked up a 1st gen 8GB Nexus 7 from eBay, it was sold as faulty (they said it doesn't power on) it does actually power on, Windows 7 connects and i can access the storage and i can hear my finger presses on the screen so i know it's powered on and the digitizer is working however there is no display whatsoever, i have taken the back off and reseated the battery connection and all ribbon cables to the digitizer / LCD assembly and nothing, the LCD looks immaculate there are no fractures or bleeding, absolutely no signs of damage yet it just stays black? I suspect the short ribbon cable to the LCD is at fault but before i order a replacement is there anything else you guys can think of?
Hi.
Just replaced my old battery with new one and after that... suprise - screen won't turn on.
Tablet works ok, I can hear sounds, vibration, I can even hear taps (so touch sensitive layer is working fine) but screen is dead.
Inside there are only 3 connectors, one battery, one in the upper part and one in the lower, both firmly placed and in full contact.
Is there something else I am missing?
Screen was working fine when I opened tablet, so there's absolutely no way to damage anything during opening. Worked without back cover.
Then I turned it off, replaced battery and turned on, and now screen is dead...
Any suggestions, help? Any connectors that could disconnect?
Or any possibility that screen was damaged when unplugging old battery?
Plz, guys, you're so smart
And how the lcd connects with motherboard?
I have samsung i9505 with broken screen after fall. I could hear phone booting, light at the front was working. I bought another full screen with frame and replaced the old screen. After replacement nothing changes, except for buttons at the bottom of the screen, they light after touch. What can be wrong? How to check this? Phone is identified by computer, I can look at all files.
It's possible the replacement screen is defective or the motherboard connection is loose or damaged.
