Help! Flat display and button cable!! - 8525, TyTN, MDA Vario II, JasJam General

Hi, some days ago my phone has been dropped
Although the impact has not been strong since then, call buttons are bad jokes, sometimes work others do not, then I opened the device for control but I did not find anything broken and welding again the connectors on the flat and on the motherboard, the situation has improved but sometimes still the same problems, someone know where I could find a flat cable to replace my or have any solution to be proposed?
Many Thanks!!!!

Wizard Display broken?

Hi guys, I need some help here. I literally threw my wizard out of the window shaking out my bedsheets and it dropped three stories into the backyard.
When I turned it on again (the drop had opened the battery case), at first the screen was bright white, then turned darker and darker showing some sort of noisy stripes (static, not moving). When it goes into standby and is turned on again from there it does the same thing.
some facts:
- there is no visible crack in the display (neither from the side, I disassembled it)
- all buttons and the touchscreen are still responding (u can see that because the background lighting responds to them)
- the wizard is still accessible via usb
- I don't know whether the phone still works because I can't enter the pin w/o display.
It seems strange to me that the display should stop working while the touchscreen and the background lighting remain unhurt. I am thinking about replacing the display (only available together w/ the touchscreen and bg-lighting), but I am afraid that it might rather be a problem with the communication between the main unit and the display, even though there was no visible damage there.
Does anybody have experiences with that kind of behavior of the display?
Is the display that vulnerable that it breaks before the rest (light, touchscreen)?
I didn't find any cases similar to mine in the forum. If there are and my questions would be answered there, please direct me there.
Thanks for the help

Try taking it apart, the force of inpact could have made a connection loose.
Disassembling I disconnected everything possible. Next thing would be to take apart the display/bglight/tscreen.
did you mean that? looks pretty fragile to me...
thx
yeah, I wouldnt mess with the display .. lol .. I meant a connection somewhere inside the device... like a loose ribbon or something
Yeah, seems hopeless. Guess I'll have to buy a new display and hope it works :-(
I'll post again once I got some results...
Problem solved
For the archive:
I exchanged the display and apparently only the screen was broken and the rest was unharmed.
I'd also like to add that two days ago (1 week after I repaired the thing) I dropped a plastic bottle on the phone in such a stupid angle that it broke the touchscreen. the next thing I will report here is whether it is possible to exchange the touchscreen only by doing some soldering.

Screen display scrambled fades to white - ideas to fix?

Hi, i have been experiencing a screen display problem.
When i power on the Hermes the screen does not power on.
If i then place the Hermes on a hard surface and press down hard on the long sides at the edge of the screen i can make the backlight and display appears.
However, if i release this pressure the backlight remains on but the display will become scrambled. The scrambled display is variously showing white noise, scan lines, mispositioned graphics, and ultimately fading to white.
Also, if the phone rings the audio is distorted and crackling.
I have dismantled the Hermes as far as removing the housing for the LCD from the rest of the phone. I then opened up this housing and disconnected / reconnected the LCD flex cable that is by the very edge of the housing. Then reassembled phone. No improvement was made, in fact the display issue was made more tempermental!
However the phone stil works as i am using it at the moment as a 3g modem for my laptop.
But it is extremely frustrating / near impossible to use it for any other purpose in this condition!
I am wondering as to what the problem could be and how i might solve it?
I am thinking that the problem must be due to a poor connection / oxidation / dry solder somewhere.
I would appreciate advice as to what i could do to solve this issue myself.
Next steps???
>>> Would there be any use in spraying a little WD40 into cable contacts?
>>> Someone has suggested passing a heat gun over the PCB to bond any solder that may have cracked.... Although i am sure that this is a trick that can work with old PCBs that he plays around with i am not so sure that this would be such a good idea on the flimsy multi layer boards in the Hermes.
Let me know what you think of these ideas...
white screen
Hi..not sure which version of the hermes you have, but this has been a common problem for years. My Cingular 8525 did the same thing. I finally figured out while placing the phone into a desktop charger that it was putting pressure on one lower corner of my phone and it would go white. It got to the point any pressure on it would cause the screen to fade to white. I contacted AT&T tech support about it and even though fone was out of the warranty period(over a year) they sent me a refurb ATT branded 8525 at no charge. I've had that one now close to two years with no problems.
Hi Oleschuldad, thanks for your reply. I have the Hermes100 branded as the "ORaNGE SPV M3100". Yes i have read that the white screen issue is a major blight for the hermes phone. From what i have read It seems that there are numerous causes and the problem can be difficult to trace to a specific component. The problem that my phone has is the opposite to the what you had with your phone. In that i must EXERT PRESSURE on the phone to be able to read the display. The indication is such that i am certain that it must be the result of either loose connection / bad solder / corrosion somewhere.
Think that i will get a can of electrical contact cleaner spray and clean the contacts on the flex cables.
Looks like corrosion is definitely an issue in my phone as there is some green oxide on the round watch type battery that sits on the main board next to the contacts for the main battery.
I will have to strip the phone down again at the weekend.

Low signal strength

I just recently sent my phone to the shop so they can fix the digitizer, it broke on my pocket when I sat on it. After that the signal strength has gone drastically low, can this be a hardware malfunction or VPN issue? Thanks for the help
have you tried to update radio? its a good place to start. what are your system specs? what rom are you running. there no such thing as to much info when asking questions my friend.
I did not understand if your problem has appeared after the replacement of the touch ..
still looks like a hardware problem, the black coaxial cable that goes inside the black volume button may be loose (almost certainly) his fixation on a snap ring of 1.5 mm.
regards
I think you have broken (or lost connection) one of the four connectors which rely on the casing (which is the antenna on the plastic case)... see picture http://img862.imageshack.us/img862/9258/htchd2disassembled5.png

HD2's innards: Attempted vibration motor fix gone horribly wrong.. HELP!

I'm hoping somebody with some knowledge of the HD2's innards can help me...
My vibration stopped working on my HD2. I found the plastic LED flash cover to be 'pushed in' (with the help of a couple xda threads I dug up). Others said it was an easy fix: Open the case and push that piece of plastic back into place.
I opened up the case to correct it. But after putting it back together not only does vibrate not work, but the volume keys, speakers (both earpiece and speakerphone), flash, notification led, and camera all don't work.
I obviously screwed something up, but I have no clue what it could have been. I was very careful. One thing I'll note is that when I pulled the case apart, the plastic volume rocker went flying. When putting the phone back together I got it back into place so that I THOUGHT it should work (it was seated properly and felt "clicky" for up/down movements.
But clearly wasn't just the volume rocker that was affected. It doesn't seem that I pulled anything else loose or anything like that...
But no luck, all that I listed above is non functional, and what I'm left with is a glorified 3.5 in tablet
Any ideas?? Thanks in advance!!!
Snapped a couple quick pics which may help:

Unfortunately when comparing these to other pictures of the inside of the HD2 that I found online, I fail to see any differences, or anything I could have inadvertently screwed up.
Most likely you screwed up(or disconnected from motherboard) somehow your main flexboard, but your picture are not usable for this, you should take off your motherboard+main flexboard from chassis to have a full view!
You probobly just disconnected a small cable. I have no idea of the HD2 innards but did multiple repairs of small stuffs and the flat cables hold in place by a plastic clicker pull out easily - just reopen and check them all, you should be fine.
Thanks for the input! I figured it's something like that, just one small cable. But I didn't even take off the board at all... The pictures show the full extent of the disassembly... Do we still think it's necessary to disassemble it further?
I checked all visible connections, but yeah, maybe I somehow yanked out something that is NOT visible. I'll try to check again today... In the meantime, any more ideas from anyone else? Thanks!
For al that to be not responding I would assume main-flex damaged or as mention before maybe connection to mainboard got moved during pulling cover !
Volume button can be troublesome, sometimes the little plastic caps come off but if it felt clicky should be good in that respect.
also be very carefull of thin spring metal legs that contact antenna pads on back cover, one near screw above & right of vibro motor looks a to be a bit flat. They bend easily & break easily too ...
Have u tried starting up the phone without the backing? I had this issue when I painted my housing the led cover was stopping the motor from spinning but if i took out the backing it works. So I just trimmed the led cover and now it works.

Click to expand...
Click to collapse
I'm nooby with regard to this stuff; I only attempted the repair since I read in a couple other threads about multiple self-proclaimed non-super-tech savvy people were able to open it up and move the plastic LED cover for an easy fix.
So what exactly am I looking for with regard to the main-flex? Where is it? I thought I wouldn't really see that unless I removed the board which I haven't done... is it still possible I knocked it loose or damaged it? I didn't think that would be possible since I ONLY removed the back cover (though it does take a slightly uncomfortable amount of force to do so, so I guess anything can happen...).
If not the main flex cable, is there anything else specific to look at which may be disconnected? It seems to be all the stuff at the top of the phone that fails to work (camera, speakers, vibration, flash, volume keys). While the stuff on the bottom (other hardware buttons, charging jack, headphone jack, etc).
THanks!
I have given up. After being stumped briefly how to hard reset the device without the volume keys working (I have Android installed), I was able to do it via ADB from the Android dev kit.
To ebay I go...

Loudspeaker not working after replacement of Charging Dock

Guys, I bought and replaced the charging dock from my N9005, because mine got damaged in a tragic accident involving me, the charging cable and the phone itself... Now, after the replacement itself, I have noticed that my loudspeaker does not work at all (missed my alarm this morning, thought I overslept, but I had later on the phone in my hand and it rang... but without sound.
After a bit more tinkering, I have noticed that if I just put the back panel (the one that contains the speaker) on top of the phone and press gently, it works, but if I put in the screws and push it properly, it stops working.. So my option right now is to either leave it flimsy (too flimsy for the back cover to be put on top and still function), or to not have a speaker at all. Any suggestions, what I did wrong, or which one of the two components you guys think might have been the one to break? The new charging dock, which also contains the contacts for it, or the speaker's connection itself? I took as much care as I possibly could when I did it, but still... Help, please?
help?!
