Hi everyone,
I sat down with my Nook in my back pocket today, and when I got up it was frozen on the startup screen, displaying "Nook by Barnes & Noble" and 5 dots with the first filled in. Since then the screen has not changed no matter what I do.
The device is responsive in two ways. Firstly, when plugged into a computer, the contents of the My Files and screensavers folders are visible and interactive. Secondly, when plugged into a computer or wall socket, the charging light comes on orange, and if the power button is held down for 10 seconds it turns green briefly, then goes back to orange. No change whatsoever is observed on the display, not so much as a flicker.
So, that being the case, any suggestions for fixing it? If the current display cannot be salvaged, is it worthwhile to try to buy a dead unit and Frankenstein a functional Nook? If so, how much could I expect to pay?
Thanks in advance!
New NSTs are currently going for £30 in the UK, so I'd put that at the top end of what to pay for a used one.
There's a 0.01% chance that the display connector needs to be reseated.
Open up your Nook and try reseating the connector.
Thanks! I'll go ahead and try reseating the display connector as soon as I can find a T5 screwdriver.
My Nook gets display frozen as well
My Nook Glowlight is in the exact situation as the OP.
I tried to reseat the connector to the screen on the mainboard by opening the rear case, no luck.
Any suggestions?
update: I replaced the mainboard with the one from my fathers, who has the same glowlight, it works. So it seems something is wrong on my own mainboard, not the whole main board though. Have no idea where to fix it.
I have a same issue with Nook Touch...its stuck half on "connect to charge" screen and only 25% display is working. Is there any guide on reseating the display connector?
Reseating the display connector is only a shot in the dark.
I don't think that that is the problem, but it would be stupid if it were.
There could be many things that cause the display to die.
Power circuitry is always suspect and the eInk uses higher voltages.

Before anyone jumps on me, I've been going through the Wiki and forums extensively, and found just one similar problem. Which wasn't solved...
My HTC TyTN/Hermes 200 won't boot up anymore. It is totally dead. I even can't get it into bootloader mode. Screen stays blank and the LED is off.
Put the (3 months old) battery in another Hermes to test it, and it's at 100% charge.
My Hermes shows a steady red LED when it's plugged into power without the battery in, and no LED at all when the battery is installed. The red LED turns off when the battery is installed while there's power going into the unit.
I've left the battery out for at least an hour, plugged it back in, same results. Like the other guy I tried the "pull power, pull battery, plug in power, plug in battery, reset" trick http://forum.xda-developers.com/show...6469&p=1077622 - to no avail.
Does anyone have any last resort ideas on how to get it to at least come back up to a boot loader screen ?
check the battery contact points on the phone. the hermes shows a red led when its plugged in but without a battery
... have you ever dismantled your hermes? your screen ribbon cable may have dead tracks or not be connected properly
just a test on the opposite side of the battery connectors with battery removed press firmly without putting pressure on the LCD, this worked for me when i had a white screen on power up.
if this fixes the problem you may need to actually dismantle the back and put some flame retardant electrical tape on the back over the existing tape to add an extra layer of pressure and retension

Yes, I have cleaned the contact too, nothing. And the battery is OK for sure, my colleague's TyTN runs on it without any problem.

In fact I have, I have totally dismantled and reassembled my TyTN yesterday afternoon, nothing.
the only other problem may be that when being dismantled you may have damaged some sensitive components, Electro Static Discharge will fry sensitive CMOS components, they do not like it at all, whenever dismantling you should wear an earth strap, any time i dismantled mine it was on a workbench with a static mat and i was earthed through the mat.
but this is one possibility, the only other idea is to swap main board and displays with another that works, finding someone willing to allow you to do this with a working hemes is the tough part.
thats as much all i can think of for now
R.I.P. my trustful Hermes 200
Thanks all for your assistance. I have come to the conclusion that my sweetheart is no longer among us. May she rest in peace.
I have obtained a (2d hand) replacement yesterday. May this one last longer.
I'll keep the old TyTN for replacement parts.
Oh well...
Yesterday my Hermes 300 just seized function and now i'm unable to use it.
When i power on the screen just turns white and thats all it does. I can connect it to my pc, get stuff from my SD card and connect it with Windows Mobile Device Center.
Is there any way of saving this Hermes with software?
This means that one 'side' or 'half' of the ribbon connecting the LCD to the mainboard has been lifted (during normal) use. Thus the backlight wires are the only ones connected. This is an easy fix if you are willing to take the unit apart and re-seat the LCD ribbon to the mainboard.
hmm, not what i hoped for but i'll give it a shot!
My nook is rooted. I nearly always use it plugged to the wall outlet to save battery live. I use it mainly to read pdf files using "OfficeSuite". When I start up my nook I activate to the app "Nook refresh" and "Smart Rotator"(to use my OfficeSuite in landscape mode).
Some days ago I installed a screen rotator app (from http://forum.xda-developers.com/showthread.php?t=1678431) and couldn't use it, so I uninstalled it. I do not know if this can have any relation with the problem that I am having with the screen.
Some days ago my Nook screen was perfect, no strange thing.
But one day I noticed a horizontal line (from the usual perspective, with the "nook" button below) that was dark/white (that is when the background is white, the line is black and viceversa). I did not give it much importance.
Another day, while I was reading a pdf file, appeared another horizontal line.
Today, while I was reading a pdf file, appeared another horizontal line.
That is 3 lines for now.
What could it be? Do you have any idea to solve this issue?
Thank you.
If you power off and then power on again, do the lines go away?
I would not recommend using the NST plugged in at all times - I think you will do better to let the battery cycle.
E-ink is attracted to and repelled from the screen by electrostatic charge, as I understand it. So if there's anything like a power surge or other mechanical issue affecting your unit while charging, possibly you could see an artifact in the display?

I did this with the wall outlet disconnect several times, but it does not work. The lines are there.

Why do you think that? I do it because a read that when the battery is fully charged, the light turns green and not continues charging the battery, so I suppose that direct energy is feeding the use of the device instead of charging my nook.

No, the only image that appears on the display when I power it on is a SD CARD image informing that there is a sd card.

They're probably permanent if after unplugging, powering off all the way, then powering on again they persist. If your device is still under warranty, I'd suggest resetting it to stock and getting a return.

I thought about that a little more. On the NC, if the device is plugged in, the screen tends to behave very strangely - detecting nonexistent touches or accepting input, but then repeating it (fast page flipping through a book, rather than turning one page.)
The charger on the NC and NST is not its strong point (the NC in particular, but I've never liked the fit of the NST chargers much - on both of my devices, they tend to seat at an odd angle and need to be pushed a bit to seat correctly) and I've always wondered how well the rest of the device is actually isolated from current when it's plugged in.

I've just had the same happen to my NST. First a single horizontal line, now two.
Did you ever resolve your problem?
Same here. One, two, three and yesterday appeared the fourth line! I have the Nook more than one year. I noticed the lines everytime after charging, so it could be connected. Discharge, charge, reset, nothing helps. When I will buy myself a tablet or a new reader. I will open it and pay with some display connectors.
I ended up returning mine to B&N as it was still under warranty.
But I'd be interested to know what you find if you take yours apart. It kinda sounds like a loose connection somewhere...
Hey guys.
Basically I've recently replaced my whole screen assembly on my Nexus, but it turns off after a few seconds when it's not on charge.
Sometimes it'll last about a minute but will instantly turn off. I've tried a factory reset and it still does the same thing.
I've bought a replacement battery, just making sure that there's nothing else wrong with the phone? any advice etc would be appreciated.
Thanks.
If it started after you replaced the screen, then its likely that something isn't seated properly on the inside. I changed my screen too, so have a look at the battery connector and the connector that connects the bottom board (the one with the charger port) to the top one.

It was doing it before I changed the screen.

In that case it probably is the battery. New one should fix it.
Please for advice! I had to replace the motherboard on my G2 D802, I think everything done correctly. After turning the phone on, the display remained black and refused to turn anymore. I put the old board with that previously loaded, but now it is the same result. I asked friend and took his board and ribbon cable (kit) - Alas, the result is the same, namely: pressing the power button, the phone vibrate briefly flashes the upper led diode green and blue - the screen is black. When is connected with the PC being recognized, even updating software in this state. I think the display has a problem or his ribbon cables .... I do not understand much. I hope someone advise me what I can do or where to read !!
Thanks in advance !
It's very possible that the ribbon cable broke if you weren't careful. If that's the case then it's not something you can fix and you would need a new screen. It could also be that you aren't seating all of the connections properly. Take it apart again and note ALL of the connector locations. While you're in there, VERY CLOSELY inspect every millimeter of the pcb and ribbon cables for damage. If you don't see anything, carefully reassemble it being sure to squarely lines up the ribbon cables before firmly seating them(you can mess up the whole board if you press on them too hard if they're askew).
I reviewed the cable but nothing impressed me. Because I am the second owner, assume that it is possible to display is not original, but some cheap fake. Is it possible this option ?? Attached pictures:

From the pics, that display does not look like it's fake. The letters and cable itself looks to be identical to the one I took out when replacing my screen. If it worked fine before taking it apart, it should still work with the new logic board.
Btw, when I was replacing my screen I didn't correctly seat one of the two ribbon cables that go across the battery and my display was also black even though the display cable itself was correctly installed. After taking it apart again and methodically taking note of every connector on both sides of everything and very carefully putting it back together, it fired right up. That's why I said to check EVERYTHING - it doesn't necessarily have to be the display/cable.
Good luck.
