Hi,
The keyboard stopped working on my device so I opened it up to find the tiny flat keyboard cable not properley seated on the mainboard. I tried putting it back but 1)its SOOOO tine and fidley, and 2) the tiny plastic saddle / clip bit that holds the cable down broke in half.
I suspect it may have been cracked already somehow and that why it came loose.
Anyway, anyone know where I can get one of these little clips? Any tips for putting them back together?
Thanks!

Hi
Forgive me if this has been posted before, but this is my 1st post here & need a little 1to1
My touch screen on my Qtek 9100 stopped working a few days ago, the phone is ok, i can make calls & use the manual keypad.
The phone was left uncharged for a few days & when i went to use it again the touch screen was not working.
There is a dent in the screen that i did not notice before, its only about 1cm, actually its more of a scratch than a dent.
The screen looks fine, no cracks or black spots visable.
No life from the screen, whatever part i touch.
Can someone advise me on what to do to get back up & running.... I have already done this.....
Hard & soft resets
Installed latest ROM.
Phone is currently stuck on the the "touch screen to setup your mobile device screen"
I have already ordered a new touch screen from the net,
should i just change the touch screen or are there other things to try first?
Any advice welcome like

Cheers
any luck? im having the same proble but with my atom exec and everyone seems slightly blank on this
When the touchscreen went bad on mine, it turned out the cause was a tiny, almost invisible hairline crack in the touchscreen's ribbon cable which severed one of the wires. I had to use a magnifying lens to see it.
It was possible to test with a multimeter. On the back of the LCD is a piece of clear tape covering where the touchscreen ribbon is soldered to the LCD. You will need to lift the tape to expose 4 wires from the touchscreen. With pressure on the screen, there should be a resistance around 1.2kohms between pins 1&2 and the same between pins 3&4. On mine, pins 3&4 were open circuit.
To fix mine, I didn't change the screen. I removed the touchscreen ribbon from the main LCD (accidentally tearing the solder pads off the ribbon - I wasn't sure how it was attached). Then I used an X-acto knife and scraped off some plastic from each side of the break. Then I soldered a TINY piece of copper wire no thicker than a hair across the break (a single strand from a stranded wire). Since I accidentally tore the solder pads off the ribbon, I scraped off some plastic from the copper traces there and soldered some wire to them and soldered that to the LCD. That did the trick, it's all working now!
i have this same problem.. i was using the qtek with the cracked digitizer but when i did the hard reset it took me to this screen. is there anyway we can get off this screen? help plz!!
I just dropped my A7, no damage, everything running fine, except there is now a small openning around the power button and I can't get the mat plastic to clip tight like the rest around ...
I didn't try to open it completely and re-clip it ... would that help ?
I need to fix this. Any ideas?
There are 2 "covered" screws (you must have torx) by the "dock port". Once you have unscrewed the screws, slide the back cover out, then you can snap the side panel back in.
So tonight I was replacing a broken digitizer for my HD2, it was anything but easy, but it wasn't as bad as I was expecting. Anyways, in the middle of reassembling, I hit the point where I need to reconnect the keypad. I was fighting with it for a good 10 minutes trying to get it connected. I grabbed a small flathead screwdriver to push the ribbon while my other hand guided the ribbon into the connector. In the process I broke the ribbon cable.
Of course, for the good of the phone, I've ordered up a new keypad. My question is, is there anything I can do in the interim? Can one say, line up the contacts on the ribbon and electrical tape it together? Or anything else?
Man just wait for the replacement keypad. Cause as thin and delicate as the ribbons are you will probably do more damage than good to the ribbon. I mean even if you got the ribbon aligned and tapped bake together. One you probably will not get a good connection between the two pieces of ribbon, and two the little copper strips are so thin you will probably cause micro cracks in them while you are fiddling with the two half's of the ribbon.
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.

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...
I purchased the wireless charging cover for my Droid 4, and two LG wireless charging pads for work/home. I can't stand the beep it makes when it begins charging.
I opened up one of the pads, hoping there was an obvious speaker with some wire leads I could cut, but it's not obvious to me what makes the beep. I've attached a picture of the board if anyone has any input. I'll update this if I figure something out.
Here's a guy that pulled a speaker off the PCB with pliers, but didn't describe which component.
The speaker is actually the large box at bottom-right. I ran a knife around the edges and pulled at it with some pliers, and the top of it came off like a cover, with some piece inside. The beep is no longer emitted without this piece.
at first i couldnt figure out how to remove the back but found the screws under the four rubber nubs.
I followed the directions on the amazon link posted and pulled the entire black box off from the circuit board!
I put the thing back together and it now charges silently. I really dont see how this thing ever left the design room after the prototype was made with that terrible beep sounds
Component PZ1 (Bottom Right on that picture) is the buzzer. The other black thing with glue around it (Reference L1 on the silkscreen) is an inductor, which is very likely to be part of the charging circuit or voltage regulation circuit, removing it would end in tears, as was the case with one of the guys on that Amazon page.
Also, I strongly recommend against yanking parts off PCBs with pliers. Depending on how strongly it's held on you could crack the circuit board or damage neighboring components. You really want to clean away that adhesive, being careful not to cut the PCB, and then use proper desoldering equipment (soldering iron and solder wick, hot air gun, etc.) to remove the speaker.
What's the best way to get the back cover off? I can't seem to rip the rubber nubs out.
Ok I got the back cover off, but I'm having a hard time taking off the screws that hold the circuit board to the back.

I have a hard time with mine as well

Ok, I finally got sick of hearing that annoying beep. So I searched it and found this post. Did the deed and fixed it. Thanks for all the help.
Now, I would also like to find the notification sound that comes on when I place my phone on the pad.
If I turn my phone sound "off" it doesn't make the sound (obviously). But I have gone through all the settings to try to find where I can switch it off permanently.
Unfortunately I can't find it. I thought it would have been under Settings/accessory/Dock Sound but that was not it. Does anyone know how to turn off this notification???
