Every time I try to reinstall logic board on n910t the S pen does not work.
There is a flex cable in the back for the S pen that is suposed to be connected to a socket in the back of board but I'm having a hard time trying to do that. It's kinda of tricky.
Does anybody have a way or method to do that? I don't want remove the display just to connect that flex cable.
Thanks
Does it plug I'm somewhere and you have to clamp it? These are small components so you might not recognize everything immediately.
I unlocked your mum's bootloader.
Not sure I quite understand. Sorry
Is the cable a ribbon cable and do you see a place to hold it and snap down probably a black or green piece of plastic on top of it or perhaps a slot that you force it in to? Upload a picture or two so maybe we can help. Not familiar with innards.

I used a straightened out bobby pin to push the ribbon connector up as I placed the motherboard into the midframe. You'll need some light to see in there and it's kinda tricky but you"ll know when it connects . Also you can connect battery and test before you go any further to avoid a lot of work.

i replaced my kaiser screen and the only thing that i got was a white screen so i was wondering if someone here had the same problem and got it working properly again.
Check on the Kaiser thread. Someone posted the same issue, and I think his screen connection wasn't tight, and it came loose.
don't think thats the problem connection seem all okay but if you could find the thread link please post it.

thx but no one posted a solution...
Provide more info...
did it turn white immediately after the screen install or did you try to install a ROM or what?
If white right away, then I have bad news for you... you will need to recheck your connections... all two of them..., I know it is pain in the Ars but it is needed.
If you attempted to install a ROM and then the white screen, then it is a Software issue. To track back, do a hard reset and see if you get somewhere. Look in the wiki section for hard reset instructions.
yeah it turned white immediately after i installed the screen like in the picture

Ribbon Connector
I had the same thing happen with my wizard a while back. Make sure the ribbon connection is in all the way. Assuming the ribbon on the kaiser has the same type of connector as the wizard, there is a piece of plastic that you lift up to unlatch the ribbon, make sure that bracket is open, then stick the ribbon in all the way (it went in farther than I would have expected) and then push the little bracket back down to clamp the ribbon down to the leads. Make sure the ribbon is perfectly perpendicular to the clamp also (not entering the connector crooked). And maybe check to make sure that you are routing the ribbon correctly, where it is not being pullde out or loosened when you open the screen. I'm pretty confident that your problem lies somewhere in that ribbon connection. Anyhoo, good luck. I'd take you some pics but I just gave my wizard to a friend & I don't wanna open my kaiser. Yet.
i have a similar problem, any ideas on this?

hmm i think i already tried it. i even putted a new ribbon in but it doesn't hurt to try it again...
problem solved screen wasn't the same type as the old one a repair store fixed it. so the number on the screen gots to be exactly the same as the old one
Hello everyone,
Yesterday i disassembled my diamond to solve a problem with the keypad, that was protruding out of his place. I figured out that it was a structural flaw and with the help of my instruments i solved the problem.After that i assembled back all pieces, but when i tried to power on the device it works coz i can hear sounds and other stuff, but lcd screen is not powering up.
So i noticed that the ribbon flex cable was a bit damaged from the aluminium cover placed under the battery. I suppose that the problem is dued to that, but i'm not sure of it. So i need a confirmation that the LCD power is connected to that ribbon cable, so i can purchase the replacement. Thank you. The cable is the one in the attachement.
bump.
anyone??
up, noone knows the function of that piece?
yes, u need to change tat cable
yes, i supposed that. If someone knows the role of that piece i'll be grateful ;P
So...I took apart my Nexus One to clean the dust from under the screen. I've done this before, but it back together and it worked. But this time, after putting it back together it wont power on. I sometimes get a vibrate after pressing the power button. One question though. This time I noticed that one end of the coax cable on the left of the phone is broken and there is no plug on it. Would this be the problem? I don't think it should though since I'm guessing it connects the GPS antenna to the rest, and I dont use GPS on my phone. Any help would be good.
EDIT: I think I didnt connect the LCD good enough.
The co ax cable must be connected to the logic board. If it won't click in connect it then secure in place with a small piece of tape.

As I said, the top plug of the coax has been ripped off.
Do you know if that's the problem?
Again, when I push the button it vibrates like it usually does on boot, but doesn't show anything on screen.
I pulled out the board again, trying to find the problem.
EDIT!!!! I just noticed on the LCD ribbon cable there are a few bent pins. I think that will be my problem. I'll get it back together in like 15 minutes and report back.
EDIT 2!!!! So yea...two of the pins came off, and are way to small to find. Guess I need to order a new LCD.
Crap, new LCDs are $60+
Hi
I tried to replace my battery and after assemble it back i only get a black display when turning my m7 on.
I broke this little plastic thing from the display cable off (look in attachment)
Is this thing essential for a working display? (i thought i can fix it with a drop of glue)
Should the display work when the backcover is off the device? Because there are some connectors on the backcover....
cheers

Shouldn't have done that, I think you accidentally broke something. I'd send it to a HTC service center. But that's gonna cost you probably.
nah, official repair isn't worth it. The phone is more than 2 years old...
and yes i think i broke something... thats why im asking
You're gonna have to be good with a solder and a couple of tiny wires if you want to revive your phone.

You definitively need this clip to be intact so the flex cable sits firmly in place otherwise you'll have bad contact between the cable and the pins.
If you don't want to send to HTC for repair you'll need at least to send it to your local electronic repair shop so someone skilled with the proper soldering tool (not the standard iron you have at home) can replace the connector. BTW some of these clips must be lifted from the cable side and some other from the opposite side of the cable, so next time use tweezers and apply very light force on each side you'll find from what side it must be lifted.
LCD should work fine with the back cover removed, afaik. Connectors in the back cover are often for antennas but I wouldn't recommend to run the phone with antennas disconnected to avoid damaging the radio chips (reflected power).
If you are from the US, you can easily find this connector on ebay for about 10$. I'm sure it won't be that much expensive to repair if you bring the new connector and the phone already disassembled to your local repair shop.
Btw are you sure its only the LCD? When trying to boot the phone can you here the HTC theme or does it vibrate? Recognized by your computer when connected with usb?
thx for your response
I found an replacement part on ebay but first i have to look for someone who can solder this for me.
When i try to turn it on it only vibrates without a htc theme sound and there is no display reaction.
The other thing i mentioned is that the phone gets very hot in the middle (should be the cpu) where i dont know if it should get that hot.
I have to try the pc connetion again and let you know asap.

I'm not really worried about the absence of HTC sound when booting, if your phone is on silent / vibration mode, it will only vibrate when booting. If your computer does detect it once booted, then I guess the broken connector clip is the problem.

Here is a video about the connector replacement, it doesn't look that hard to replace but wouldn't recommend to do it yourself if you never soldered electronics before. Soldering isn't that hard but you need some practices and knowledge to make good joints. I don't think your phone motherboard is a good candidate to practices yourself if you never did it before. You'll also need a really tiny tip for your iron, probably a type "L", 50/50 solder + some flux. Flux must be cleaned after use to avoid corrosion. The most difficult when soldering on motherboard, imo, is to find the right temperature. If your iron is to hot, you'll damage your connector. If its not hot enough, solder will take more time to liquefy and some heat will be absorbed by surrounding components which can cause irreversible damage.
Easy fix mate
You don't need to replace the connector, I've done this before, it is just the connector clip that has come off and it goes back on reasonably easily.
You will need a good magnifier.
You will need a good light source.
The phone held securely on its side with the socket pointing up.
Some masking tape on the loose part because it WILL go "ping" into the distance if you don't and you will not find it.
Look at the other connectors to see the proper orientation for the part, mark it with a permanent marker on top and at one end.
The insertion looks difficult, it isn't too bad, keep the part nice and straight and the motion is kind of like clicking it down on the ribbon.
Forget replacing the connector, that is 100 times harder.
If you do lose the loose part I have one or two laying around.
Good luck.
Tried to change battery and unfortunately I broke the flex cable to the side button. Is there a way to turn on the device?
hi, i guess the answer is too late, isnt it? did you change the flex cable?
in general, a switch just does a short circuit. as you can see in the schematic, you gotta short circuit pin 5 and a ground pin of J2701. (i did not test it with my device but in theory it should work. i am not responsible for a damaged device so be careful ;P)
