Hi
I opened up the s730 all the way down to the keyboard to be able to put some glue on the broken keyboard frame.
Adfter the phone was assembled back again, the screen does not rotate when the keyboad is slided in and out.
Anybody who knows were the sensor is located?
I have the same problem, but it happened when I changed the housing.
Everything seem into place, but the d"#$%$ keyboard does not work.
Regards,
OB
I also posted about this exact issue, doesn't anyone know where the sensor is?
not all time is about a spoiled sensor because the sensor can be conected with mainboard throught the flex cable if it is broken will not work specialy when its a chase replacement , the flex cable can be damaged very easly
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
Hey guys,
The USB port of my HD2 broke off and I was forced to replace the motherboard. When I assembled the HD2 again, I could immediately see that there was something wrong with my screen. The screen couldn't display full color (only bright red/orange/white/dark green/cyan accents). Also, the 'hang-up button isn't responding anymore after I replaced the motherboard (and flexcable).
What happened? Is there something wrong with the lcd display or did something go wrong when I (dis)assembled the phone? I took the motherboard and the flexcable from another HD2 that had a broken display.
Thanks in advance.

So you completely voided your warranty through HTC and tried to fix the device yourself, then screwed it up. I'd still say send it to HTC and ask for a repair. I don't know if they'll do it or not, unless you used official parts. I know they do out-of-warranty repairs, but they'll charge you.....
Yep you screwed up the repair, those ribbon cables need a delicate touch & any handfisted moment ends up with what you have got now ...
Another careful strip & inspection of all ribbon connectors is needed ...
I bought it as a second-hand phone. The guy didn't give me a reseat and the HD2 was flashed a WP7 ROM.
For the button problem, how are you turning your phone on without that button? do you hear/feel it click when you press it? If not its just misaligned.the buttons are on a flex ribbon cable with two holes on each side. it fits on the plastic middle frame of the phone which has two small spikes coming out of it... it has to be perfectly placed for your buttons to actually click..
if the flex ribbon is broken however you can buy one off ebay for arround 10$ any will do, mine is not original works fine..
for the screen you could have messed up the lcd, did you separate from the glass-digitizer? if you did you probably screwed it up.. its not a easy thing to do.. also was not necessary for your repairs
the connection to the motherboard might not be all the in and clipped which might cause your problem... (being that two of the little pins provide voltage and ground while all the others provide data information if one of those pins is not in all the way a piece of data might not be displaying for example a color. Never seen that happen its theoretically possible thou)
well I have only opened my phone 3 times and dont claim to be a expert.. but this is my take on it... Good luck!
@pablow Thanks for the detailed response.
The HD2 is only turned on, after I place the battery. Otherwhise it won't start.
I hear a click on the (broken) 'off' button, everytime I press it. I also noticed that the inside of not all of the 'spikes' are empty. I can see a bit of the flexcable in the spike of the broken 'off' button. The spike of the (working) 'call' button is empty.
I think that the flexcable hasn't been connected securely to the motherboard. I'll try connecting everything again tonight.
not that it makes much difference but HTC wouldn't of fixed it through warranty because of usb damage anyway
I thought so, thanks for the heads-up anyways.
[Solved] Display is fixed
Update:
I disassembled the HD2 and reconnected everything (from coax to flexcable). Fortunately it worked! The display is how it should be.
I have another problem now. All of the buttons don't work now, exept for the dial button. Do these buttons break so fast? It's annoying as fuark, because I have to disassemble it another time in the future to fix the buttons.
I also couldn't re-attach the volume control tab when assembling the HD2.
Hey guys I have a question. I recently changed the screen on my note 4 to a new non cracked one. Now I tried the screen with the s pen before I took the phone apart so I knew it worked. Well once I got the phone all back together the s pen on the new screen doesn't work anymore. What would control the s pen in the phone hardware wise that would make it stop working? I tried all the software troubleshooting ideas other than reloading the rom. Anybody have any ideas?
Probably the s pen ribbon cable not connected properly. I had the same issue when I personally repaired my n4. Realized it after the same issues u have and had to separate the lcd from the frame to easily connect both ribbon cables the same time.
Thanks. I'll check it out.
Did you manage to fix it? I have same problem. I got mine fixed at a phone repair shop. When I remove the s pen, the air command pops out but when I touch the screen, nothing happens.

Hello guys, Yesterday i changed the battery on my phone. After putting everything back together my screen stopped working, with no image and no touch function. The cable on the right bottom is connected but perhaps i damaged it in some way..
The phone is working properly, if I connect it to an HDMI it works.
Any ideas on what I may have done wrong and the solution?
I took it to a shoo and they say I have to replace the whole screen (USD 100 approx) which seems too much..
Check this coil. If it's shorted it's ok, if not make jumper on it. Also check filter (small bricks) under the LCD flex connector and LCD flex itself if it's not teared. Those are common damages which can be done disassembling this phone.
Yup it's the LCD flex that is dammaged.. Is it possible to repair? I'm guessing that on a shop they will want to change the whole LCD screen..
Unfortunately there is no way to change flex only. If it's damaged You have to change whole screen.
Ok, oh well that's life... thanks for the help though!
