HELP! Housing replaced, now orientation doesn't change when keyboard is opened!

I changed the entire housing on my Hermes as it was looking a little battered. All seemed ok but now when I slide the keyboard open the orientation stays in portrait mode. Also the keyboard light stays off. I've tested another keyboard pcb from an old broken hermes and the same problem persists.
Does ANYONE have any clue as to how I could fix this, or if it's even fixable. Not as bothered about the backlight....
Also my internal mic volume has gotten really low. I have to switch to loudspeaker unless i'm in a really quiet room!
there is a magnet in the housing that triggers a switch to swap the screen, did you swap it over?
It'll either be what beermonster65 said above, or possibly the ribbon connector which connects the screen to the mainboard isn't plugged in properly - I had that when I opened mine up to repair the sliders.

As far as I knew I switched over everything from the old housing. What does this magnet look like and where is it? If i've lost it is there a possible fix?
Thank you both for your responses so far.
Any news on the mic issue also?

LCD-side speaker troubles

Hello,
I need help - have tried my best but still can't fix my uni.
The LCD-speaker is not working when case is closed with LCD faceing out.
It does work when LCD is faceing keyboard and uni is not closed (then it switches to Logo-side speaker). I have tested it by rotating screen and the speaker stops to work in very exact moment more-less in the middle of rotation.
As I have looked in manual (http://forum.xda-developers.com/showthread.php?t=349573). The LCD-coaxial cable dosnt have any axis-based connectors there, so basicaly it is just a tighten bunch of wires. So I pressume there is nothing broken as some connector or etc. So as I can think it is not wire-based trouble as the speaker is working when LCD is not rotated (is facing keyboard).
Did anyone met this problem? Maybe some software fix? Any ideas?
Regards,
woocky
I use to have exactly the opposite problem, that is, my external phone (ear) speaker didn't worked after my uni fell, the cure was easy, open the uni, clean the speaker's and the pcb's contacts, gently pull the speakers golden contacts, close the uni, and that's it!

Help me - I dropped my qtek!!!

I just dropped my qtek S200. When I turn it on noe, I just see colored stripes, but the qtek seems to work normal, because if I use the camera button you can hear the "click" sound e.t.c.
What shall I do know? Please help me - I am quite in Panic know .-(
Please anyone?
Did the display cable come loose? You'll have to open the unit in order to rectify this. As I have just ordered a new case, I have searched for instructions how to do this and found
this step by step manual.
Good luck
Robert
Thank you very much for your help - I will try this out. I hope I can open it, because I am not very good in this.
How does the display cable look like?
I got stucked at this step: NOW CAREFULLY LIFT THE BACK COVER AWAY FROM THE FRONT AND NOTE THE SHORT SPEAKER CABLE, USE YOU TWEASERS TO CAREFULLY DISCONNECT IT
How do I disconnect it??
What exactly does the device do? Does it respond to charging? Does the screen have any response to being switched on?
The qtek works properly - that means I can use the com button and touch the screen where eg the bluetooth used to be and I can turn it on.
The camera button works too, because you can hear the click when taking a photo.
The only thing is, that you can only see vertical colored stripes on the screen that change their color after some minutes.
I just opened it now, but it did not help.
you have to buy a new one hahahaha

[Q] Could use some hardware help

My daughter's device has been having all sorts of problems. Her backlight stopped working so I replaced the Digitizer and the LCD screen but that didn't help at all. The calibration doesn't work and the screen won't rotate. In addition, her headphone jack is on the blink as well. Do I need to replace the motherboard flex cable or is there something else going on? The ambient light sensor seems to be on the fritz as well which might explain the backlight not working. The phone is using stock Android. Thanks for all and any help.

[Q] New screen not working after replacement

Hi all,
I had a touchscreen issue (sometimes not working) in my HD2 so I ordered a new fabric screen+lcd assemby. I replaced it very carefully but now when I plug new lcd it is not working. Phone is working, buttons, vibration, hear the sound when turning on but there is only backlight on display and just shows black screen. I am sure that display is ok because I tried to put old one (wich was still working before replacement) and it has same issue (backlight works but display is black). Can you give me some ideas what is wrong ????
damaged lcd ribbon connector on mainboard or ribbon not being inserted fully or latched securely
Ty booting to bootloader ...
Help
The flex cable is not attached correctly or the main board is broken and before you close your phone try it. If you can't do this give someone your phone and he will recover for you.
