[Q] Screen permanently turned off while performing service for my G2. - G2 Q&A, Help & Troubleshooting

Hello Guys.
I got some problem with my 3.5mm jack, so I decided to order a whole new tape with USB connector and 3.5mm jack port.
http://thumbs2.ebaystatic.com/d/l225/m/mRfGTPTIX7tNp0yCo0_JEmQ.jpg
Got the package with small toolkit to open phone and change this thing by myself.
I've followed instructions from one of many youtube DIY movies.
New parts got installed, everything went pretty well... then closed phone. Turned On... and here I em...
Power button doesnt work, I see no light around the power button, no screen reaction... But I hear that phone turned on because of LG logon sound. Phone reacts while pluged in to charger, USB->PC too.
Attached picture with exact conectors I plugged off while changing parts inside.
Why power button doesnt light up? Why doesnt work? Is there some small connector between power button and the board, because I dont see any, there is a Toshiba Chip just beneath the power button/volume part.
Please help me, give me some advices what exactly could get wrong.

Possibly the contact, which is used to detect if the keyboard is open, might not be working.
Mikechannon is the hardware guy on the hermes and im sure he will come across this post at some point
ok thanks but the thing is that i didnt replace to i guess the guy who did it is goin to have to fix it
Hi
I don't have one opened up in front of me but yes Mrvanx has it I think. One of the multi connectors is either un-plugged or not pushed in fully. There is one that is quite liable to "pinging" off unless it's firmly pressed home. No guarantees but I'd be fairly confident that that's all it is. The guy should have checked it after the repair!

This is the likely culprit. It's easy to forget to press it home as it curls itself round on its mylar cable and rests on the connection (ie looks connected but may not be pressed into the connection). Good news is that it's not a major dismantling job. All it needs is the back off to reveal it.

This happens if there is even a very momentary loss of power. Before assuming anything too complex, I would check to make sure the battery is absolutely firm against its contacts. You can insert a strip of card between the casing and the battery. See here:

}
If the problem remains, then I would suspect one of the internal flex cables.

thx for fast answer mike
testing now ^_^
i second that
I had the same issue with an extended battery. I used some duct tape to make a tighter fit and havent had any problems since then. I guess a strip of card is a better idea, but duct tape seems to work (plus its more manly ).

On/Off Button Hard to Responce

Hi all. My elfin's On/Off Button seemed hard to trigger since couple of days and is there any solution to resolve it? Attached is the screenshot of the On/Off button. Thanks in advance.

Try to open your htc and check the button

you meant to disassembly it?
Well, you may have to dissemble it.
My elf has the same problem with the on/off button. I opened the unit and the problem is that the little switch on the circuit board has failed because it's not springing back after it's been pressed . The switch is very small and looks difficult to replace. The camera and reset buttons use the same type of switch, so I'm considering removing the switch used for reset, and soldering it into the on/off switch position. However, as I mentioned, the switches are very small so I'm worried that a heat gun or soldering iron will damage the board. Anyone know an HTC parts supplier that may sell these little switches?

[Q] Brand new : NOOK Simple Touch- Wont turn on

Unboxed the packing, Charged the Nook for 3Hrs. It wont turn-on on pressing the power button on the back. I have tried long press for as long as 1min. Still no help.
It just displays Fully charge the device before first use !

}
It show a green light when connected for charging.
One more thing is that when I connect to the computer, It shows some error USB Notification - "USB Device not recognized".
I have seen a few things about taking the nook apart, I think it would be my last resort. I don't replacement is viable option as I got it shipped to India.
Hoping some one would help me out.
It seems that the charging system/battery has gotten out of whack.
Usually people open the case, disconnect then reconnect the battery.
It could be that the battery is bad too.
It's good that it shows something when plugged into the USB.
What exactly is the unrecognized USB device PID/VID?
Replacement
I thought of taking it apart but it has break seal on the screw. Didn't wanna void warranty .
Thank you for the help ! I just found someone to take it back to the States. B&N will replace the device.

Dasaita Max6 10.2 inch not responding to touch

Hi guys, I just bought and installed this and it took me the whole day. Sadly the unit's screen is not responding to touch. Has anyone experienced this? The buttons to the left don't work either-i would've at least expected those to be responsive.
Whats super weird is the unit does not load. It boots up instantly... Don't these things need load/start up time. It booted instantly as soon as I plugged it in... Thought it would've been a cold start.
I made some videos to help show the problem.
Appreciate any input. As you can see I tried the reset button which is responsive.
I should have mentioned I also tried unplugging and plugging to no resolve as well
You are not holding the pin in the hole for long enough to do a full reset. You have to push the pin in the hole and HOLD IT until the button lights flash, then let go. It takes about 6 to 10 seconds of holding the reset with the pin.
If that doesn't work then there is probably something wrong with the outer touch glass. Maybe it's not fully plugged into the board.
The capacitive glass has a small ribbon connector on it like in the picture. See if that connector is properly plugged in.
