Help me! How to fix my keyboard-T-Mobile MDA Vario II - 8525, TyTN, MDA Vario II, JasJam General

My PPC is T-Mobile MDA Vario II, yesterday I pull the keyborad but found some keys are not available, which are "U""J""N"".""P","UP""DOWN", the background light is ok for these keys, but no response for them when I key in, btw, other keys are ok.
Anyone in this forum ever met this problem? what is the most potential cause of this case? thanks for your commetns.

Sounds like one of two possibilities. Different I believe from the often reported "unresponsive keys". That's where you have tp push a bit harder for certain letters. So for you I think it's either:
1
The keyboard multiconnector is loose/poor contact,
2

Solutions:
Hopefully a warranty repair/replcement
If not then local repair or some diy.

Mike, thanks for your quick comments. I decide to disassemble my ppc to double check if conductive membrane is set up properly, but I feel curious why other keys could work under the same membrane, hopefully i could find the key after disassembly.
Mod Edit: We now know it's not the membrane:

DIY Screen Alignment FIX

Don't know if this has been posted yet or not (I went 3 pages back and saw nothing) but the problem with the screen alignment is that there is a sponge pressing against the digitizer.
You'll have to open your device and remove this sponge strip and the screen alignment issue will be gone.
If you have warranty on your device, it is suggested that you get it repaired through your warrant, but if your a DIY person, then go ahead and do it (opening your device will void yoru warranty).
Since i don't have a TyTn myself, i can't do a step by step guide but check this link out, there are some pictures of the process.
If this process indeed fixed the issue, then it's good to know!
Anyone here has tried it ?
I am still waiting my MDA Vario II !

I have posted elsewhere on this board my solution - which is similar but whilst I removed the gasket I replaced it with a thicker one and firmed up the retaining clips on back of screen. Mine is still fine, but there is a lot of trial and error involved with these solutions. One site I saw was similar to the solution above - a japanese site where he found just taking out the original seal and not replacing it with anything made the problem even worse!
To be honest my personal view is (even though I did my own fix) is get it fixed/replaced under warranty. Slack keyboard maybe a different matter as the fix is rather more certain, but again if you dismantle a device to fix a slack keyboard and you did not have an alignment problem - beware the dismantling may create an alignment problem!!

What is the fix for a slack keyboard? At least half of my keys don't register after the "click".

Sorry when I say slack keyboard I'm not refering to the missing keys or hard press issues but to the loose sliding and clicking into place mechanism of the keyboard.

Sliding Keyboard getting loose?

I just picked up another 8525 after returning the first one to checkout the Blackjack. I wanted to make sure I at least tried it before my 30 day return policy kicked in. I noticed on my second 8525 the keyboard does not lock into PDA mode as secure as my first one. It seems that the top part of the phone locks better then the bottom. So when I hold it has a phone I tend to slide the keyboard open a little. Has anyone had these issues? It just seems to easy on the second one to unlock/open the keyboard.

I'm afraid this is a fairly common problem. The metal runners/sliders have small indents at each end (cannot see these unless device is dismantled) that create the click into place when the sliding blocks attached to the base part slide over them.
These indents are often too shallow to create a nice firm click and in extreme cases the actual runner has sprung apart where small micro welds have broken.
There are fixes for this but only for those that don't care about their warranty and want to dis-assemble the device. I have done this fix and it now requires a very firm two thumbed push to open. However I do not recommend you do this when there is the possibility of exchange/return or repair.
Mike
If you decide to do it on your own I can vouch for Mike's method. He emailed me the process and I posted it on the WIKI.

Sounds like its possbile then. Where in the Wiki can I find the how-to? I looked and could not find it. Thanks again for the information.
It is under the hardware overview at the bottom. andMike i added some props to you for the method!
Mike, you must of really nailed this process. I guess I have to try it now.

Yes Worked perfectly!!!
I have not done it yet, but plan to soon. To clarify what your fix does is that it tightens the sliding keyboard rails? or provide a better click when its closed?
Just read your site. I think that answered my question. Thanks, I will try and post my success (...or failure).
Great fix. One of the little but annoying things about the device fixed.
sliding keyboard then freezes
hello, I got my device ! I'm very happy but when I slide the keyboard, and here the left 'click' then it freezes.
It is very strange, is there anything I can do ?
Thanks in advance for any suggestion

I don't think the "clicking" mechanism is what's making your device freeze. I believe its the display going from portrait to landscape mode what's probably making it freeze up. Have you hard reset to make sure there is no 3rd party today plugins that are having issues with switching to landscape mode?
sliding keyboard, frozen device
dear brmcguire, thank you for your answer. I think I have to be more precise.
When I slide the keyboard and stop before the "click", it is ok, it moves to the landscape mode without problem. Then, when I push untill it locks, on the right lock it is ok but when pushed untill the left lock, then it freeezes. To be precise, "freeze" means that the menu bar opens, and the tactil screen does not answer anymore to the pen, (I can still use the buttons).
That is why I believe it is a hardware malfunction, but I'm still a newby
Does anybody had a similar problem ?
Any help appreciated

Ok, I see. It does sound like a hardware issue. I would try exchanging it for a new one.

I think we're all agreed it has to be hardware. There is no software that operates when the "left" edge clicks into place. There are two circuits that operate softwarewise when the keyboard opens
1. There is a small magnet operated switch that changes portrait to landscape and that's working fine,
2. The light sensor above the "p" key top right which operates the keyboard backlight.
I don't think either of these is responsible.
At a guess either the Multi connector Mylar Cable for the screen/digitizer connection is getting trapped/pulled/stretched and partially breaking its connection or the click into place is creating an internal squeeze against possibly the "windows" button hardkey next to the Green Phone Key.
I think like brmcguire that I'd get it back to shop while still in warranty perhaps after doing all the usual things like a hard reset - just in case we're all wrong and it is software.
Or you just never quite open it far enough to click into place. I do this a lot, partly because I've got a really firm click into place on both right and left sides that if I'm just quickly using keyboard I find I can get every key without the final clicks.
Mike
thanks
I tried hardware reset but no change. Anyway, thank you so much for your anwers. Not that it works better, but to feel support is quiet healing.
cheers !

I think you're right, maybe we need a Hermes counselling and psychological support group. All charges forwarded to HTC of course!

RE. loose keyboard
CAN someone give me the direct link to the wiki page bc i couldnt find it i dont know why, if you know how to do it you can also send me the directions but PLZ someone send me a link thanks again
Did this fix after fighting with a very loose slider from the beginning. This and Mob6 software and I love my TyTn again.
Thanks for the instructions and thanks for the wiki.

Stylus problem

Sice a few days i can slide easily the stylus of my TyTN in and out - to easily. Nothing holds the stylus. The well known problem!
I asked the german HTC support for a solution - still waiting...
What are the solutions? If i turns out exchange, do you think new devices don't have this problem any more?
thx

Unfortunately it's just the well known rubber block that comes off. It's a very easy fix just glue it back in the right place. Problem is that if you take the back off you void any warranty you may have.
See here:

I had the same problem. While I was replacing my digitizer and LCD I looked for the rubber block and it was still there - so I bent the tab down and adjusted the plastic part that grasps the point of the stylus and all is well again.
Pics are floating around in the WiKi or on mikechannon's posts.
Thanks for the link.
Since the device is only some months old and I wouldn't like to lose the warranty, I cannot open it unfortunately. Is there a other way/solution?

The only other option you have is to send the device back under warranty.
The dealer offered an exchange of the device to me. Alternatively he will turn back the device and refund the money to me.
What do you think, are the new devices better in that point?
When does the "Kaiser" come out?
In the meantime I read in another thread that the error arises very rarely. Surely?
New Poll Created...
When reinserting make sure it's secure
I and some others had the loudspeaker wiring disconnected when the shim ended up being jammed by the stylus into the bottom of the silo.
Search my previous post for details and pics.

My sound seems to be ok. It's only the slide/lock problem.
This was very common with the HTC Wizard. With my Hermes it gets loose everynow and then; it kinda fixes itself. Like sometimes it will just fall out, and other times its snug just like new.
Wierd huh?
so i'm gonna vote no on the poll because it barely bothers me.

HTC Hermes fell on the floor - on-button does not respond

My HTC Hermes fell on the floor. Fortunately, it remained largely undamaged except for two little things: The on-button and the camera-button do not respond anymore when I press them. However, the buttons do not seem to be completely destroyed: They just seem somehow disadjusted. I notice that from the sound and the movement when I try to press them. I might be able to get them back to work if I could just open the device or at least use clamps to pull the button and readjust it.
Has anybody ever had similar problems, or could give me any hint as to how to fix it without breaking the device.
Of course there is no warranty, otherwise I wouldnt be so foolish as to try to open it up or use clamps.
Thanx in advance for any hints.
Cheers
Michael
are u 100% there is no warranty? even if you bought it from ebay try contacting htc directly.. dont tell them u dropped the phone obviously.

The Hermes is actually quite durable. Chances are the button switches just need tweaked back into position.
Have a look here under Hermes Practical Fixes.
http://michael-channon.spaces.live.com
One really obvious/not so obvious thing to check is that the battery is still in position. One report I saw was where a guy dropped his Hermes, thought it was totally dead but it was just that the battery was just out of position.

intercompatibility of parts between Herm100/200/300

Hello all
I require some input from some of the gurus of xda-devs and its a question im guessing a lot people would like to know the answer to
Can we swap spare parts from say a Cingular 8525 to a MDA Vario II? (Herm200 --> Herm300)
what i mean to say is, lets say we could only find a front keypad for a cingular 8525, would it fit into the vario II?of course the orientation of keys would be correct for the cingular and not for the vario so you'd need a new front keypad aswell, but on the 'technical' level, is this possible?
many thanks
Don't quote me on this BUT I believe I read a post from Mike Channon saying that internally ALL the Hermes variants were the same. Be best to search through his threads, website or ask the maestro himself...
Cheers...
Yes that's probably about 99% true, BUT I notice the d/pad layout on some variants is quite different and so the underlying board may well be different - have not had time to fully check this.
Mike
Thanks for clearing that up Mike, as I said I wasn't totally sure...
Cheers...
many thanks
so mike, my theoretical scenario, would it work?
if i was to get a cingular 8525 d-pad board and a 8525 keypad to go over it, technically it ought to work right?

I tried to check that out and did not find much info. BUT I see no reason for it not to work circuit wise. You might need to remap keys.
Have you checked that the 8525 keypad will fit the housing you have?
Mike
id happily modify the housing as a temporary thing, but i reckon i'll give it a shot and report back. i have a hunch it will fix the white screen issue.
does anyone know of anyone who has a brick they'd like to sell?!
Ebay is good, bought a couple of dud jasjams off there to fix mine and wouldn't you know it, one actually worked except for the camera & battery. Ended up cannobilizing MY Jasjam to fix up the "broken" one I purchased for parts....
Cheers...
