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!

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...
Hello,
I've been flashing my Blackstone since I bought it a year ago, used many different ROMs, TASK 29, latest ROM I used was MaryOne - Build 23568 - WWE [300410]. There were some minor problems but otherwise it was working good till today.
In the morning, phone was connected to USB for activesync and suddenly died, it doesn't want to turn on, not even a diode turns on when I plug in the usb cable to show that it is charging, anybody could give some help? It is in warranty but I'm not sure, what they will say if they'll get in and see cookend rom in it any solution how to avoid it?
Same problem here. Has been flashing Energy ROM for the last couple of weeks but I dont think it is a software issue.
Prior to the present state of totally dead (ie. no LED light when charger is connected, cannot power on, pressing ON switch will not power/turn on phone neither can I hard reset), the phone behaved strangely by resetting itself during video play and phone switched off by itself.
I suspect it a hardware issue. If so, which parts and where can I purchase it without going thro HTC authorised dealer to pay a ransom! Or its time to dump the phone and upgrade? - HELP!, any suggestion?
I have no idea what you could do, but if you decide to
upgrade, please contact me. I would buy the broken phone
because I need a tiny metal part from it, as you can read in my other thread.

I had the same problem a couple of weeks ago.
I sent the phone to htc and they changed the motherboard. This took alltogether about 4 weeks.
bgumble,
Thanks for your input. I could only find motherboard flex cable online : http://www.globaldirectparts.com//ProductDetails.asp?ProductCode=HTC730080&Click=1710
Maybe you can tell if the motherboard also house the flash ROM? If that is the case I guess the motherboard is only available via HTC service centre! or purchase a faulty unit from ebay with a working motherboard.
Yes the motherboard houses the rom.
the only other major pcb (print circuit board) is the top flex pcb which AFAIK doesn't house any of the flash storage or any other major chips.
if you want to DIY repair, you can use the service manual and I have some tips/advice in the bottom link in my sig, even tho its to change the screen, you can omit a few steps and use it to change the mobo if you're confident doing such a repair.
IIRC: mobo houses the cpu, ram, flash, various transistors and i/o rails, the usb socket, radio nand, coax rails. it also is connected to the wifi/gps/bt/sd/sim pcb, but they are seperatable.
Thank you for you info, qwertylesh.
Having replaced the LCD for TYTN II and checked the service manual and video to dis-assemble HD I think I can manage. But the only problem is getting the spare part, motherboard!. I am hoping to bid for a faulty HD but with a working motherboard on ebay.
I tried placing my dead HD, well wrapped in plastic bag, in the freezer for 2 hrs and then out in room temperature for an hour. Replaced battery but same results - will not power on.
With the charger plugged in, there is no LED lights but testing the terminals which comes into contact with the battery terminals there is voltage (4.19v), meaning - it is charging the battery but the motherboard fails to bootup!
Would it be possible to fix the motherboard? - a long shot!!!!
depends on what is exactly causing it to not boot up I think.
weather its a problem with the flex PCB or the ribbon + power button PCB at the top of your mobile or weather it is actually the motherboard at the bottom.
My HD was dead during upgrade
My Phone was dead during upgrade can anybody help me?
I found a way to repair using JTAG method but unfortunately i stuck up unavailability of JTAG pin outs.
Touch HD Mainboard
I too am in need of a new main board. I packed up my touch HD and transported it in it's original box 150 miles couple of week before I powered it up again and the phone starts, responds to volume up/down and connects via active sync. Basically it all works apart from the screen, no back light and can't see anything on the screen. The phone will charged the battery but there's no light on the power button. I've opened the phone up and disconnected the flex PCB and the connection between the main board and the screen but still have the fault.
Has anyone managed to get hold of one?
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.

Did you solve it, i have the same issue.
i'm disassembling my HD2 after it dropped in water ...
the screen were working properly but while i', trying to disassemble the digitizer with some parts the screen became black
what can i do ?
thanks in advanced .
Yes it will boot normally with those parts as I do that to test all HD2s prior to final build up.
Issue I see is button board cable looks to be cut. I use a spare button board cable to power phone on as when laid out like that the original one obviously will not reach socket on mainboard & a spare button board plugged in mainboard is easiest route for this kind of testing ...

thank you for replying ...
actually I'm using an external wire to power on the device because my button board cable is corrupted ...
do you have any idea about repairing the black screen while booting ?
i can't buy any part for my device ... i'm in the besieged "HOMS" in Syria
Might be best let it dry out further before adding power as normally leave handsets for about 4 days to be safe ...
What signs of life are you getting when powering on with your wire ?
If on WM OS you could use MyMobiler to try & get screen image to PC as would give idea on actual possible issues. could be ribbon or connector or worse.
Not a good time or location for a wet handset :-S good luck ...
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.
