No Touch - 8.9" Kindle Fire HD Q&A, Help & Troubleshooting

So I have in my possession a very nice kindle fire hd (8.9).
A friend of mine says that she locked it by accident somehow and I said, sure I can fix it.
The problem is it doesn't detect touch. It's not frozen and I've done a lot of research on the matter. I took it apart, put it back together. Nothing. the clock works and so do the buttons but no touch is detected. I know I can get an otg and connect a mouse but while that ships (I need one anyways) I'd like to get this to work.
I've actually had a similar problem with my phone (e4gt) where the touch screen wouldn't work with certain chargers. I ultimately learned that its some sort of grounding issue. Besides that I've never heard of this happening on any device even.
Any help would be greatly appreciated.
Also its in pristine condition. No wear or water damage in the outside or inside.

I don't know about the touch issue, but I can say that a mouse won't work unless it's a very low powered one or you use a powered hub. Just giving you a heads up,

Would a Bluetooth one work? except there's the problem of setting it up.
I think i'll root to diagnose better.

Fixed
I got it. One of the cables was upset or something because when i unplugged and replugged it it started working. Broke some things here and there but it's all cosmetics,

After using motorola in-car charger, touch screen isn't responding!

Ok, I'm getting desperate now. Not sure why this has happened. Tried resetting the device and nothing. Tried flashing it witch stock rom and now I can't get past the telephone provider setup as I can't touch the 'Next' button. Has anyone had a similar issue and if you have, please tell me there's a fix for this as I think my manufacturers warranty has ran out as I bought this device when it came out.

I've got no advice for you but I'd just like to say I have never heard of a charger causing this problem before EVER.
right. if it's a genuine motorola charger, I even would say they are more reliable then oem.
anyway it's not making sense, because right behind charger connector goes power management IC which wouldn't send higher voltage through but would burn instead.
First I would try to test the digitizer, it should have around 500 ohms resistance on terminals for both horizontal and vertical when not touched. you can test it while still wired.
if it's working ok, then change the digitizer controller. I didn't have rhodium opened yet but from pictures, it looks like it's on mainboard so you probably can't do it yourself.

[Q] Crazy digitizer issues

Just activated a Epic 4G Touch last night. Been playing with it pretty much ever since but I'm having a strange problem with what appears to be the digitizer. If I put my finger on the lock screen and hold it there at times it will start jumping around in a crazy fashion. Is this behavior normal for the lockscreen?
It will also sometimes stop half-way through a homescreen pan in touchwiz and otherwise behave strangely and/or unresponsive sometimes selecting things that I have not pressed. The keys on the bottom are also sometimes unresponsive. Anyone else having a similar issue?
I did root it but did didn't mess with the kernel or anything else. I used this method:

I haven't seen any posts relating to this so perhaps I have a defective phone. Anyone know if a Sprint store would swap it out or do I have to send it back to Amazon (where I purchased it)?
It appears to be due to the wall-wart
Well, I've tracked the problem down. This digitizer issue only happens when I have the phone plugged into the wall using the Samsung 120VAC to USB adapter (the cube that came with the phone). No problem when the USB cable is plugged into the PC or through a different adapter that I had laying around.
Now I'm curious, can someone else try this: Plug in your phone with the Samsung adapter then turn it on and hold your finger on the screen... see if the lockstreen starts jumping around on you.
Thanks.
A number of people around here have noticed the problem including me.
Yeah man it's a known issue with pretty much everyone's phone. A small annoyance if I decide I want to use my phone after I've plugged it in for the night.
Also towards the end of the charge cycle and when it's fully charged, the problem will subside. Only when it's pumping a lot of power into the phone.
Try using a different adapter it works for me.I have my old Samsung captivate adapter and that does not happen anymore
Sent from my SPH-D710 using XDA App
I used another adapter and it works fine. Looks like there is a defect in the Samsung ones then... I'm just hoping its not doing any damange to the phone as it's obviously sending a lot of electrical noise into it. None of the local Sprint stores (I tried 3) would swap the adapter for me since I brought it on Amazon. I called them and they gave me credit to buy a new one so I'm happy.
Thanks for the responses, glad to have cleared this up. Going back to root.

[Q] Scrambled/garbled screen on T-Mobile G2 - flex cable problem? Please help!

Hi all.
My phone's display has been getting progressively worse and worse over the past couple weeks. Initially, when I flipped out the keyboard, the screen would get garbled. I could technically still interact with it (it still responded to stuff), but the display would start glitching out and move all over the place. It's like there's tons of scanlines and it repeats the same display again and again.
When I went back into portrait mode, things were fine. This was extremely awkward but I dealt with it because I had little choice.
However, over the past couple weeks, the problem's gotten progressively worse. Holding my phone a certain way would cause the screen to glitch up again. It came to a point where I had to flip out the screen and keep the flex cable positioned a certain way so I could see the screen. I'm using a dull edge to kinda poke that flex cable around and it helped me gain use of the phone, but today it's gotten so bad now it refuses to "undo" itself when it boots and no amount of poking and prodding of the flex cable will help.
It looks almost exactly like this guy's phone (not my video):

A few seconds after bootup:

Luckily, I was able to get a VNC server installed on the thing, so if you guys think it's a software issue, I may be able to get it to do something, but I'm not going to be able to interact with the phone if I put it into Clockwork Recovery mode, so doing a hard reset is out of the question.
I'm having a flex cable come in and I'm going to get some local assistance disassembling and installing it, but before I do that, had anyone had this issue before? What did you do to fix it?
best guess is you need a new flex cable

power/charging issue

ive been having a problem with this phone for a while. it has a problem with turning on and statying on. i will set it on charge while its powered off for atleast two hours, but as soon as i turn it on it will last for about 5 mins and turn off.
i first replaced the battery and it has the same problem. so i replaced the charging port and it was working fine for a few weeks and now its back to the same issue. i cant even get it to charge now
so just trying to figure out what kind of other components it could be
Disclaimer: You're at a more advanced level than I am. I've never done phone repair, and I don't know enough about phone hardware to say if there are other components that could be responsible. I'm a software guy.
That being said, I'll chime in with what I do know, on the off chance that it's actually helpful.
When computers get too hot, they do an automatic thermal shutdown to try to prevent permanent damage. I assume smartphones do this as well. You're on XDA, so there's a good chance you like to tinker. Did you overclock the phone? Overclocking generates more heat, which could potentially lead to a thermal shutdown or permanent damage. Or you might be using or storing the phone in a hot environment.
Have you tried using a different charging cable? Maybe the cable or its connector went bad. You could also test the cable with a different device. Maybe the wall outlet, etc went bad. Did you check the connectors that the battery attaches to, to make sure they're clean?
When you opened the phone to replace the charging port, maybe you didn't put it together quite right, so over time something came loose or got pinched. Desktops and laptops use various types of adhesives such as thermal paste, and computer technicians have to remember to reapply new adhesive when putting a machine back together. Maybe phones use some adhesive too, and maybe you forgot to reapply it?
Hopefully someone more knowledgeable about phone hardware will chime in, but the Incredible 2 section of these forums has been a ghost town lately. That's why I'm giving my two cents. If it were me, I'd just buy a new phone.

well i greatly appreciate your lengthly response. to be honest, it is my mothers phone, which is why i want to try and fix it. i gave her an iphone so she really doesnt need this phone but i would like to figure out what is wrong because i do like to tinker with things. i have tried different chords, wall outlets, usb ports on the pc etc. i will reopen the phone to see if everything is back together, because thats the only thing i can think of from what you mentioned.
thanks again. if anyone has had a similar problem, let me know
sounds like you're either having a battery issue or need to replace your charge port on your phone. its a really simple process all you do is order the port from like amazon or ebay and the old one on your phone just unplugs from your phone circuit board there actually is a tutorial forum in the development page for the droid incredible 2 that gives you instructions on how to do this. hope this was of some help to you and if so please click thanks.

The OP already tried both of those things.
Oh ok yeah i just noticed where he put that. Hardware problem maybe. Im more into software myself than i am hardware.
MINE TOO! Omg
This... it's too much. Okay, a month ago the damned power button got too hard to press in, which should have been a warning that the hardware was getting faulty I suppose. But I downloaded an app that let me use the volume button to turn screen on/off. (I won't say which because I half-blame it, unfairly, for killing my phone
(Sorry, I'm still —mourning! the death of my phone I guess.)
The app was an ugly solution, I guess, but it worked. (I couldn't turn the screen off easily, so I set the screen-off to 10 seconds.) And I hadn't used screenshots in a while so that was no big deal; and my ROM could get me to Recovery easily enough, so screw the power button, right?
But then last night, my phone STOPPED CHARGING! I did a batt pull, tried new cords; turned off every useful app. I even went back to stock ROM, which (even though plugged in) left me with 20% batt. Might as well have bricked it, I guess.
Nothing worked. I was able to turn bluetooth back on so I could use my Air Droid acct to get my on-phone pictures, at least (everything else is safe on the SD), and then I charged it overnight in the wall and hoped for the best.
I was pretty thrilled to wake up to 100% charged! —For a few minutes. As soon as I unplugged it, it started discharging fast, and then not even the wall charger stopped it from discharging.
After brooding, for a few hours, I called Verizon tech. The tech (VERY nice, admittedly) said my Dinc2 was just dead. (Damn they're good: he was more sympathetic than a doctor delivering bad news!!) —But I feel so lost. He offered me a DNA or a Dinc 4G (and some motos and crap), but said my Dinc2 wouldn't be worth fixing. He said the power button alone was a PITA, but the dongle thing you plug the charger into was likely the problem, AND it might be the battery. Maybe he said other problems, but ultimately he suggested some pre-owneds he had for sale (I'm trying to keep my unlimited data plan), or try PhoneKarma.com. (He said he didn't recommend eBay, where they have Dinc 2s, but I'm not sure why.)
So ...do Dinc2s just have power issues after (?) 3 years? I guess that's a pretty good lifetime, but boy is it depressing. (I know — hooked on a damned phone. #Sucks.) I mean, it would be stupid to fix this one, or buy another one, right?
@Trebuchette, no matter what machine you use, rechargeable batteries do not last forever. Order a new battery from Amazon or eBay and you should be fine. They're pretty cheap and easy to replace. http://www.amazon.com/HTC-Incredible-6350-BTR6350B-Packaging/dp/B0064SI3QA
A case might make your power button easier to press. The OtterBox Defender is an excellent case that you can get for $15 used (very good condition), if a new battery successfully fixes your problem.
Hey: might be worth a shot! I did try another batt, but it was older too. And I didn't think of an otterbox at all, tbh. Thanks! Might be worth a try!
Hey: does it matter much if my USB cable is LG or whatever? I tried several different USBs too, but I'd been using this LG one (no idea how!) for probably about a year.
No, the brand of micro USB cable should not matter. It's a technical standard.
Don't buy a case until you've verified that a new battery actually fixes your problem. If a battery doesn't fix it, it's only a few bucks lost. In that case, I would then get a new phone.
i just came back to this thread after i basically put the project on hold for a while and wanted to see any new suggestions. so after leaving the phone alone for two months, i pluuged the phone in and i saw that orange ligh indicating it was charging. so far so good, im not using it as a primary phone which is good, but that would be my suggestion is to give the phone a rest for a while
EDIT: yeah scratch that, its doing the same **** now

OnePlus 5T with a broken touchscreen digitizer

I'm approaching this problem for a second time after about one and a half years of just having the phone stashed in a cupboard. I have made a post regarding this in 2018 but there wasn't any way to access the data inside back then. Now that it's been some time i'm again wondering if i can get any use out of this phone.
Basically what happened was that the touchscreen stopped responding out of the blue and never recovered. I gave this off for repairs back then (I didn't purchase hardware warranty for the phone) and in the repairman's infinite wisdom he said there is a faulty "IC" in the display panel that keeps on burning out even when replaced. He apparently did the repair three or four times but the same issue appears a few minutes after booting up.... So in terms of hardware, i know this isn't fixable.. Or atleast that our approach to the whole thing was wrong.
But now i'm wondering if there is any way to get the OTG working so i can connect a mouse and use this as a... I don't know like a tab or something. I can still get a ton of use out of this thing if OTG works. Problem is OTG was on timeout, And given that the phone was on idle for more than 18 months, OTG is now turned off. Which means unless i turn it on from the in device settings, i can't get it to work.
Any way i can get any sort of use out of this phone? I spent too much on this phone to just throw it away haha...
PS: Old thread FYI - https://forum.xda-developers.com/oneplus-5t/help/help-data-oneplus-5t-unresponsive-screen-t3824092
why not just buy a new digitizer LCD frame assembly?
