Is the backlight cycling as described?

This worked for over 20 devices for me and recently I bought another one and it worked for this one too.

Just had what appeared to be this issue with our tablet but the above guide did not fix it. As i wont be beaten by something like this. I popped the tablet open and actually found the battery connector to the PCB had partially come loose. After reseating the plug the tabet booted right up as soon as a charger was put in

Backlight not on. Does not come on or cycle after 30 or 60 seconds holding down the power button. The unit had a cracked screen but would power up and charge. Replaced the screen and now it wont charge or power on. I have tried all the combinations of button booting online, this being the last one I found (so far). I have reopened and rechecked all the connections that are part of the screen replacement process. All are tight. I even tried a battery "jump start" I found online wire stripping the end of a charging cord and then putting the red and black cables directly into the two sets of red/black wires in the battery cable clip, charging each for at least 30 minutes. Nothing has worked. Bad replacement screen? Bad battery? How can I check? Other ideas?

Did u get any luck?

Mine is the same this. No backlight at all. I hold it for 60sec and nothing. I checked the charge and she's all good. I even jump started her and nothing. My screen isn't even broken. I was using it and it died. So I plugged it in and walked away. Several hours later I tried to start her and nothing. I even d/c and the power on button and reconnected it. I don't know what else to do now. I had a lot of important stuff on there that wasn't backed up. Any thoughts folks?

did you ever fix your nexus? I'm having the same problems as you did. Bought a new screen that was already on the frame so I didn't have to do the extra work. Nothing but black screen but I can hear sounds coming from it and when I touch the screen but no picture.

I would try Unplugging power cord and plugging in a bunch of times, as mine did same thing with noise but black screen and after a while it booted up. Then again my n7 2012 has seen better days

I tried to hold down the power button for 40 seconds or more. It do turned on but, few minutes later, its froze, and the touch screen is not working.

(Frozen while on, and touch screen is not working)

Can anyone got ideas? Please reply me.

This helped for me!

Thanks! Worked Perfectly while everything else Fails!

Sally Burke - Reply

This is amazing! I hadn't touched my Nexus for over a year and thought it was for sure a failure. Works perfectly now!

*Note: This did not work until I plugged in the usb power port at the EXACT moment I pushed the volume buttons.

Mary Ellen Carmody - Reply

As Mary said above, hold volume buttons down before plugging in. When it works it looks like a very dark static TV screen. Left my battery plugged in for at least 30 mins, didn't work until I tried above. Took an additional 30 minutes after solution before it would turn on to load screen. Been charging now for 4 hours, still at only 50%. Don't get discouraged if the battery doesn't immediately charge.
