screen corrupted / faulty

I got a serious problem with my mda vario here.
sometimes, 7 out of 10 times, when i get a call the screen gets totally corrupted and jumbled like on the picture in the attachment. i can only see black vertical lines on a white screen. in order to make the screen work properly i have to turn the phone off/on (stand-by mode) then.
does anybody know where the problem is?
i have to confess, that the phone slipped out of my hands and fell on the ground 3 times so far.
thanks

well, you say youve dropped it 3 times already? is it possible that something may be loose inside? is there cosmetic damages from dropping?

yes, there are some scratches on it. i don't really think that something is loose or broken, because the screen gets only on icoming calls corrupted.
so i don't think that it is due to a loose contact or something like that...

I have exactly the same problem. I personally think it is unlikely that dropping the phone has caused it as it corrects when you cycle the power button. Any help on this from other forum member would be much appreciated.

Any resoluation this? I have the exact same problem!!

Oh dear ... somethings in the air...
mine's got it also. first time i saw it was a couple of days ago. only happens with the alarm clock in the morning :?
My phone is crap like hell... gotta hard reset and reconfig the damn thing. acting up lately...
(ps... AFAIK i barely dropped the phone... maybe 1 or 2 times. nothing more)

I have the same problem
I have read the service manual of wizard and said:
Unusual Vertical / Horizontal lines or partial display
(1) Check the connection of LCM FPC whether is properly connected. (Is a conector between motherboard and LCD)
(2) Try with another LCM. (LCM=LCD Screen)
(3) Try with another Main Board.
(4) Replace LCM if necessary
(5) Replace Main Board if necessary.
(6) Once the defective part has been identified, verify it again with the defective part whether the
symptom could be duplicated
Any sugestion?

Okay..
so far, i have installed Molski 2.26 rom (30meg free version) and upgrade the radio rom form 2.25 to 2.47.
I have not had another occurance of this so far.
Maybe a fluke.

Screen fixes when pressure applied to bottom of the screen
Guys,
I now have to keep my finger pressed hard against the bottom of the lcd unit to get the screen to display to work properly. it is under warranty with Imate but they want me to send it to Abu Dhabi for repair. I'm in Canada and concerned that I may not get it back.
So has anybody else identified this as being a loose connection rather that a real hard fault. Also has anybody fixed their unit by dismantling and reseating the connections.
Finally has anybody used the Imate repair service and was it timely & reliable?
Any advice would be appreciated.
Mick

This is a real hard fault.. had it with my mini s, took it into the shop, it was away 2 weeks... and in the end they gave me a replacement!!

I agree - took it completely apart and cleaned everything ....
And still have the issue.
Serves me right for buying something in Middlesbrough I suppose
It must be a hard fault with the LCD assembly. Will have to see how Dixons handles an overseas repair.
Take care & thx,
Mick

I had the same problem, in the end i took it into my local t-mob shop to have it repaired, they ended up sending me a new one.

Well, I've exactly the same problem since the past two-three weeks, it also occurs only in the morning. I'm living in the Netherlands and this is happening since it's rather cold over here, especially in the morning (3-4 degree Celcius). Since my bedroom window is open during the night, it gets rather cold in my room.
During the rest of the day it is +8 degree Celcius, and the phone works flawless. Maybe this problem has something to do with the Temperature?

Temperature
Bebob - don't thin so as I have had this problem for a number of months and the temp here in the summer is high (30+ degrees C)
It looks to be a bad connection type issue and may be a bad screen cable. It makes sense though that the issue is at the bottom of the screen cos this is where we press the select buttons all of the time.
Pls keep me posted on how you do. mine is going to a local repair shop (on my dime) tomorrow to see if they can fix it.
If not can any of you guys recomend a new unit that could be considered an upgrade to the KJAM ?
Many thanks
Mick

suggestions needed
friends, i have o2 mini s and got the same problem with screen for the last 3 weeks....
can anyone tell me that will the problem aggravate or else will i be able to use my cell properly for few months...
and also what will be the approx cost of repair..
all suggestions will be warmly appreciated...

It's happened to me as well. I have lived with that for one month now. It is happening, when I touch the cursor keys or when touch the lower part of the display. I tried "shaking/hitting" the xda and it looks better, so I assume it is a faulty connection cable.

I have active Cleartype and no more vertical lines for the past 2 days.
I seems to be a problem when background is white and leters are black.
Regards

similar problem
i dropped the phone (T-Mobile MDA Vario) and now when i turn it on the screen is fine for 5-30 seconds but then it scrambles, but works again if i smack the bottom of the phone on my hand!
t-mobile staff told me there are sensors to identify if it has been dropped. I'm suspicious that it could even be programmed to go "faulty" once it is dropped as the screen is fine for a limited time so it obviously works somewhat. do you know if this is the case? or what's happened? also is it a simple thing i could do myself? i didn't take out insurance so that's why i haven't just claimed off that as i'm really broke
Any help is appreciated
Regards,
Steve

whiteish screen / over temperature
hi,
I have a problem smilar at qtek 9100. I had upgade to my ppc wm5 to wm6 around 3 week ago and overclocked to 221 mhz with batery status today plug-in . 2 days ago Screen became whiteish (almost no contrast or over gamma) and working temperature is around 30c. I tried to re-flash with many kind roms but noting chaged.
Is there anybody has these kind of experice. If I can not solve. I am planing to buy new LCD ( I am not sure new LCD will solve the problem)
Thanks

Same problem here. Dropped it ONE time and the screen went crazy. Sent it to my t-mob shop and they got it repaired. They said in the report that they changed the "flex". Dunno if this helps.

Qtek 9100 - Mic & speaker dead, for the 2nd time

Hello all!
First, thanks for an awesome forum! It has both helped me tweak my Wizard, and also get help when I have needed it.
Well, I have no choice now but to ask here. Last autumn, my warranty was almost up, and a wierd problem presented itself. The mic and speaker suddenly just stopped working! The sidespeakers still work, I think, because the phone rings when someone calls me. But the caller can't hear me, and I can't hear the caller. And there isn't a hint of sound in it, no static or noise, there simply is nothing.
As there were only a few days before the 2 year warranty was up, I ran to my dealer and turned it in. A few weeks later, the phone returned, working again. But now that I come to think about it, I don't remember if I got a replacement or if they actually repaired it... It looked a little like they handled it rough though, maybe it was another phone... Well, that's not important right now.
The same thing has happened again! Summary:
1. Mic & phonespeaker dead
2. Stereo speakers work under certain conditions
3. Wired headset that came with the phone works, both for calling and media
So it seems like a hardware problem. Please note, although I downgraded the phone to original, official Swedish Qtek 9100 ROM, it has been thoroughly tweaked and upgraded to a number of different WM6 ROMs - but all that has been working beatifully!
Still, what are the odds for the mic&speaker dying twice in a row, on different phones (i think the present one is a replacement)?!?
Question: Does anyone recognize this? Is there a possibility that it is software related, and maybe fixable? I have searched both the web and these forums but haven't really found any information on it.
ANY input would be greatly appreciated!
Additional information:
Qtek 9100 (Swedish), G3 model, WM6 upgrade successful (unlocked)
EDIT: There are no system sounds, which is wierd, because the phone can still ring. I thought the system sounds came from the stereo speakers on the sides of the device?

Hello all!
It is a glorious day to be alive!!! Or to have a fully functional Wizard, at least!
Lol - my topic isn't very old, and i reply to it myself with a solution (?). I Googled after the Wizard service manual, and found it right here on Xda .
In all honesty, i didn't do all that much. I just followed the disassembly instructions of the wizard about half-way through, to the point where you get down to the back of the motherboard. I poked and fiddled enough to locate the mic assembly, only to discover that the mic is soldered to the mainboard of the phone. So, i figured i'd just leave it be, because if the mic is really broken the motherboard needs to be repleaced, or a replacement mic needs to be soldered on there.
After removing A LOT of dust in there (honestly, i think the service center that had my device last time wasn't very careful with anything, even a screw was missing! ), i reassembled it. The flat cable running to the keyboard was also a little skewed, but that may have been me, anyway i corrected it too. Same with the speakers.
Long story short, after successfully reassmbling the phone, i fired it up, called my home phone and voila! I works!
Not much of a fix, as i don't really know what i did exactly, but dust, dirt and some bad connections/soldering may have benn the culprit.
All in all, i'm very pleased with my afternoon here. Thanks for stopping by .

hi epatnor,
I think the problem with your phone was a stucked microswitch in the 2,5 mm connector for the headset. I read about it here in the forum. Sometimes the switch stays in the closed position and the phone still thinks the headset is connected. Thats why all the sound is sent to the not connected headset and therefor your phone seems to be not working (unless you connect the headset)...
But removing the dust is for sure not a bad thing...
For the next time: I think there was an easier solution for this problem than disassembling your phone...
regards
huibuh_1

Thanks huibuh_1,
Yes this was probably not the smoothest way of "fixing" it. That said, the stucked microswitch theory would actually fit my problem well - I can see now that the exact problem I was having would arise if such a switch was indeed stuck.
However, I think that the problem would be more intermittent since I actually use that port now and then - especially since it's the only way to talk (besides using a bluetooth headset that is). And since I connect the wired headset now and again the switch is used and moved, I suspect that this would result in the speaker/mic coming online again maybe..? Temporarily at least?
All the same, thanks for replying - this might happen again and with your information I'm better prepared for it!

Possibly trashed my G1

Hey.
I'm wondering if someone can lend me a hand here. I was rock climbing last weekend, left my phone in my jacket pocket, and I suspect someone may have stepped on / thrown my jacket.
In any case... it's not working right now. It doesn't start up, and there's no light when I plug it into the USB/wall chargers. Any hints on whether this thing is totally trashed? The phone was in its case the whole time, and its exterior looks completely undamaged as far as I can tell, with no scratches, etc. Another possibility is that it got rained on, but I highly doubt that the water penetrated the outside of the phone (especially given that it was in the case the whole time).
If anyone can help me getting my phone working again I would be eternally grateful.

you're kidding me,right? your phone doesn't start,no led comes on when you plug it in,and you want someone to tell you if it's trashed? did you check that the battery is properly seated?

hey whats going on? Heres what I suggest, take it to the tmobile store and tell them that the phone was charging and it started acting funky so you turned it off, and than it never came back on. From there they will switch out your battery, than if that dosent work they will just give you a new phone right there in the store. Long as no water damage which i dought it does. Just do that and you will be ok, I have done that many of times lol.

>did you check that the battery is properly seated?
Yes. I also wiped the contacts on the battery and the device.

Unfortunately it isn't quite that simple for me. I live in Canada; I purchased this phone several months ago basically new off eBay (it was used for a couple of weeks). Funnily enough, my iPod which was "naked" in the same pocket as my phone is also undamaged and continues to function normally. Are there any tests I can do to better determine the location of the problem?

You're gonna need some technical know how. Open the phone and check the mobo for any disconnected cable and/or water damage. There is really nothing you can do that you haven't already done from the outside of the phone. If possible, find a local repair shop and have them take a look at it.

Update: so basically I took out the battery, waited a day or so, put it back in, and all the buttons lit up on the phone (but the LCD remained blank and so did the charging light).
Took the battery back out, waited another day, put it back in, and the phone suddenly turned on and has been working fine since. Anyway, thank you everyone for your help.

[Q] [ help ] external speaker not working

received my dell venue pro late may 2011
i'm currently stationed in the Philippines so I had my unlocked Dell Venue Pro 16g shipped to me by a friend.
it is now June 12 and i've had the phone for less than a month. yesterday the external speaker stopped working out of no where. it was working fine earlier.
the internal speaker works fine. i can make phone calls hear perfectly. i can also insert a headset and all the application sounds work fine such as Zune
my problem is the external speaker. regardless of what volume it is on [ 0 - 30 ] there is no sound coming out
OS VERSION : 7.0.7392.0
My problem is I am stationed in the Philippines and Dell has the worst Customer Service. the last time I had a problem using my credit card JUST to order the phone and I spent over $100 USD just on international calls.
I can't imagine what it's going to cost me to talk to another customer service rep or even safely ship this back to dell and receive a new phone.
If anyone can help me with a solution. please. please do so.

I had a similar problem before I received my replacement. Try removing the battery cover and pressing down on the back in the large area above the speakers. If it's a short (like mine was), pressing down might restore the connection to the speakers and give you sound. Load up the Zune hub and try playing a song to test it.

i also had a problem like this. i restored the conection by pressing down hard just below and on the space bar on the keyboard.

ok. this is weird but the two methods actually worked. i tried both. the sound came back.
what in the world caused this problem in the first place?
i appreciate the replies. thank you very much to the both of you.

I have this problem too, I dropped the phone in its otterbox case at a significant height. I did what you guys said and I heard a clicking sound when I pressed the the area below the space bar. Sound was restored, but I noticed when I took off the otterbox case the phone loses sound unless I press hard.
The sound disappears when there is no pressure on the back of the phone, so when the battery cover is removed this problem is most noticeable. Now I would send this in for warranty, but I am in Canada and I had the phone shipped to a relative in Seattle, I doubt Dell will let me warraty this in Canada.
To save my self the long drive and hassle with dealing with Dell I would rather find a better solution. Im guessing the area where the speaker connects is loose. Is it possible if the screws came loose in that back area? Would loosening them and tightening them work. Or is something else wrong? Is there perhaps a tear down instruction manual for this phone? Can I fix it myself? Otherwise I have to leave the phone in its case for its whole life and I'd rather not do that...

Big thanks to the two helpful posts. Clicked thanks button twice for that
Anyhow, just wanted to mention that mine came loose just from plugging in and out the USB charger. The car charger has a springy cable and might be the culprit as I tag on it.

Which version did you get? Pcs or aws. Pldt uses pcs, right? My company has an office in manila and we were thinking about sending a few dvp out there.
Sent from my Venue Pro using XDA Windows Phone 7 App

I was having the same problem and tried the solution mentioned (pressing down hard) and it also restored the sound! I think this is a sign of a poor build quality.

I too was having the same issue. I had been without sound for the last week and only today, without doing anything in particular, the sound came back. I am not sure for how long though! I was going to hard reset the phone this weekend to see if it was the Mango update that caused the problem (it only happened after the update). I guess I will wait it out and see.

My DVP has the similar problem after 10 days. Actually it is not completely soundless. But the volume is too low to hear 10cm away from my ear. It may not be hardware failure. The problem is I lost my backup point at 7392 and I am in China. Any one can help me to restore to 7392?

Sounds my DVP is dead. Getting it back to Dell may be the only solution. I am thinking of buying a second-hand palm pre while the DVP away from me.

Hi,
I'd like to thanks for the solution of pressing below the space bar. It worked for me. Strange problem... Thanks !!!

a less physical solution is simply blow air into the microUSB port. keep doing it and the speaker will come back. if you have compressed air, a brief shot would do.

pressing corner helped me too, not sure for how long

Had a similar problem. If you tear down the DVP as if you are replacing the screen
Once you get the two halves separated, remove the keyboard. Below the keyboard is the "speaker" it has two small progs if memory serves if you take a small screwdriver and pry them up and reassemble all will work well .
The "pressing" solution (if it works) effectively bends the back of the cover and forces the contact.
I will try to post a teardown of the DVP with screen replacement (ALL THE WAY.. current video on Youtube stops before you have to replace the screen itself.. as it assumes you have the more complete part (with is no longer available, only the glass is now)

You might not want to pry up the speaker pins too hard though as they're spring loaded but has a small clip stopper that restrains the pin from over bending the wrong way. If you get it pass the clip, you have to make sure to put the pin back into the loop clip. It'll be more clear when you have it in front of you.
I usually just clean the contacts (pins and board side) with a screw driver/sandpaper and it'll be all good.
And a teardown will always be awesome cdgoin :good: Peeps might want to seal the LCD to the glass part with a little glue gun glue too to avoid dust getting into the screen. I find sealing the top ear piece part does the trick (bottom part helps too).

This is a strange solution but works!

Thank you. After being without sound for months and wondering if I messed up the OS or needed a hardware fix ($$$) - this worked.

Help ! Water damage . audio wont work

Hey guys I'm new here. A few weeks ago i happened to not notice that some liquid spilt on my phone while driving and i left it there like that for a while . then When i got a call and answered couldn't hear the other person. Then i noticed water on the fingerprint scanner as i had a spigen case and it had managed to get into my phone. I turned off my phone immediately and disconnected everything. Next morning i happened to removed the board and dry it out as i have done this many times before when i changed the thermal paste. The water damage indicator was red. After ensuring everything had dried out i put it back together and my phone powered back on and it charges well. But when i go to play an audio file. I get an error Sorry, the player does not support this type of audio file. The audio recorder hangs and i camera app also works but when i switch to video it hangs. Phone has been reset to factory. Same issue. Sorry for the long story. Need some Help on what part to replace. Is it the mic and speaker that's busted or some component like the DAC. If so where is the Dac located and how can i go about fixing this. Any part websites you recommend I'm from India.

Any help is nice guys. Please

My first V20 was one I bought on ebay that had sound not working. Also the camera was not working. I though it would be an easy fix, well, hoped actually, but it was not. I didn't pay much for it so I though it was worth the risk. The problem you have sounds exactly the same. Software reset won't fix it.
I did get it to work though temporarily. I put the motherboard in the oven for 10 minutes. It worked for a few days only.
The problem is that the DAC chip is now faulty due to water damage I'd say. You need a new motherboard. I would suggest buying a new v20 and keep the old one for charging your spare battery on quick charge! Or you can buy a new motherboard only on alliexpress for about 50/60 euros.

Thank you. I did consider an industrial oven. Could you please help me with temps you used? Was it the same error you got while trying to play a track?
