Screen Rotation

Hi All,
I have updated to the latest AKU3 ROMs and also a few months ago I replaced the housing...However, I've noticed that the screen does not automatically rotate when the screen is swivelled??
Now is this because I did something during re-assembly of the housing OR is there something in the ROM's that disables the hardware somehow??
Cheers

Unlikely to be the rom, since it's part of the system HTC provided.
If it's been disassembled it's more likely that.

hey VJ, sorry to bother but do you know what jumper/cable/connector/switch to jump/disconnect/tape inside the Universal to keep it from switching?

I'm sure I saw someone mention that the screen rotation is done by a magnet and switch? It's possible that maybe a small magnet fell out during disassembly? But I have looked throught the Universal repair manual and I can't find any reference to such a magnet??

I'd be nice to know exactly where it is so one would be able to take it out, if it were easy. I don't know if I wanna disasemble mine yet...
EDIT found it!! If you use a very, very light metal chain, as I did, with a keyring @ end, you can hover it around the Universal and see the tension of the chain when it's near the magnet. the keyring sticks too!
it's on the lid, behind the video-call video camera. I'm going to check the lid part of the manual.

Well taking the screen section apart is easy! You don't have to disassemble the whole unit. Looks like my magnet fell out then! Trouble is I want to sell mine so I'll just have to declare the auto screen rotate doesn't work (I've made sure that there is the rotate screen icon on the task bar though!!)

it works!! I tested it with the very small and highly magnetic point in the bezel of my tablet PC (to hold the pen) and it did change orientation.
thing is that it seems to be stuck beside the sound-holes (when the unit is closed).
I wonder how could I disassemble the lid only? are none of those screws @ the bottom connected to the back part of the lid? if so, that would be awesome!

Hi, on the xda's ftp, you'll find the maintenance manual for Universal...may help you to disassemble yours

thanx for the link!
however, it seems rather risky to try to pry the bezel open while still on the unit. Anyways I'm doing it right know. I'll get back to you.

I did pry it out and took the magnet off... painless(*) procedure and flea-sized magnet! don't loose!
I took a couple of pictures detailing the magnet position and the lid disassembled while still on the unit.
if you want to do this procedure do not loose the tiny screws and...
(*) be careful with the outer speaker (the one that lets you hear a call while the screen is facing the keyboard when closed), it isn't hard wired, it's just two small and fine contacts that might get distorted when putting the lid cover back... I had to take mine out again to correct this problem.
also, be careful with the screw driver and digitizer, as you'll be working in very akward positions to avoid disassembling the whole unit, and take off the battery of course.

Thanks for the photos - looks like my magnet feel out so I bought some 1/8 inch square magnets from ebay. It took a couple to find the sweet spot where the screen rotated but at least it works fibe now!

no problem. I'm also going to put the magnet back, now the unit doesn't now when it's closed, and therefore the outer speaker does not work. the screen also does not turn off when closed, only when the system timer tells it too... oh well.

you can turn the screen off by pressing the power button briefly.
no ext speaker though! maybe there's a way in software to disable just the rotation; i think the guys trying to get linux comfortable on the universal have some experience with it, maybe they can help.

Blank white screen....not the normal problem...

I don't understand it, the 8525 I have has a blank white screen. I thought the ribbon cable was bad so I ordered a new one, cost me $50, put it in, still the same problem. The motherboard itself is fine, I swapped it into another 8525 and it works with no problems, I swapped a different board into my 8525, and it has the same problem, blank white screen. I checked the LCD and everything, but I don't freakin understand it!! Anyone know what the heck is going on? It's annoying the crap out of me because I can't find the source of the problem.

Have you tried to swap the D-pad controller between those two devices?

Nope, haven't tried that....but I completely removed the dpad controller and still had the same problem.

Oh and the dpad IS working because I was able to hard reset the device even though I can't see anything....

Is you're void sticker gone? If not I'd say get AT&T to replace it, that's what I did when I had that problem.
Check our USB port and see if it's shorting anything? That's what happened to me. I go the white screen every I plugged in anything into the USB port.

Dpad
After loosing some screws, the problem got better, but still I have some white screens here and there. The d-pad works intermittently. When on a whitescreen, turning the device of, holding the middle D-pad key (or up together sometimes) and turning it on brings back the screen. That's why I'm suspicious about the d-pad controller. In the meantime I'm waiting for a replacement from cnn.cn and will post my results.

I notice that the service manual makes a specific point of noting the d-pad connector must be inserted precisely and with no angle. It is a very small connector and has two tiny screws. It does seem this connection is delicate and might become loose if keys on the d-pad are firmly pressed.

I did notice it too. After a lot of tries, I got to the optimum on my phone (after the whitescreens started -- probably from a fall), giving a slight torque to the screws but not too much. It's much better then before, but still.. The d-pad pressing actually "fixes" the problem, so I guess that the controller is bad or when I apply some pressure I "fix" this. It's completely random and may be related to temperature (after taking battery out for a long time, problem tends to be less often). In a few days when my controller arrives I'll make sure I screw the connector well and hoping for the best.

When I look at the xilinx(if I remember it right) fpga circuit closely there is a small gap between 2 corners and circuit board. It might be the case that the solderballs under the chip arent soldered that well and when you use D-pad the circuit board bends a bit and in a time the bad solderballs loose connection. The bad thing is that you cant check the solderballs at home (it requires x-ray inspection if you want to keep it in one piece).

FIXED IT!
I fixed it! Well, it's a bit soon to tell it'll keep like that, but after ordering a new d-pad controller from cnn.cn, and taking extra care on installing it as the technical manual says (keeping 90 degrees angle on connection to keyboard), everything is back! No more whitescreens (let's hope it stays that way), ALL buttons are back!

Wing sliding keyboard problem

hey i was just wondering if someone could help me out here, ive searched around with no luck. I replaced my wing's housing because my old one was all scratched everything works fine but i have one problem when i slide out the keyboard the screen doesnt go to landscape mode and i have no idea whats broke checked all the cables and stuff and its all pluged in, the keyboard works just wont rotate the screen thanks

You can try a hard reset, which should cure any software problems.... but if you were messing with the phone and taking it apart in order to replace the housing ... it sounds like a hardware issue.

its defenitely hardware related just not sure what it could be not sure where the thing that operates the screen and turns it when the slide is open would even be

I had the same problem. Their is a little round magnet in the front housing that you forgot to swap from the old case. Its hard to notice but its in one of the corners in the screen side housing. its under the OK button, under the circuit board. on the actual sliding plastic housing. you'll see a small round recces thats where the magnet goes.

the wing has a Prossesser Of 200Mhz, so what that means is its pretty slow.. just uninstall unused programs and End programs that your not using. Its also possible that your firmware might not Support Sliding.

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!

[Q] Do I need a replacement screen?

The vibrate function on my HD2 has not been working from day dot so I decided to open it up and check the vibrator. I pushed the vibrator in tight and closed it all up again.
When I turned on the phone, the screen was displaying what looked like 256 colours. The screen is still responsive and everything else seems to work (except of course for the vibrator).
Question is: Have I broken the screen or is there a connection problem which would cause this?
Any ideas please?

Im not really sure. Was there anything you did that made it stop working?

ok - for anyone in the same situation. I have managed to put a 3mm split in the flexi cable between screen and motherboard.
Off to ebay to get a new one now.
