stylus problems with original shield tablet. - Shield Tablet Q&A, Help & Troubleshooting

For whatever reason my stylus doesn't want to work with my original shield tablet. It works fine with my k1 though. It doesn't recognize when I remove it from its holder and it doesn't register on screen unless I apply a good amount of pressure. The screen registers my finger just fine though. I've had it apart to swap the guts (board and battery) from my bricked tablet to the replacement tablet after the replacements screen was cracked but the issue was present before that and I hooked everything back up correctly. The stylus worked fine on the donor tablet whose body and screen the guts are now in, before it was bricked through the ota. Could it be a possible hardware failure and if so what part would it be so that I can swap it back over from my donor tablet?

Now what really blows my mind is that the stylus also works with my galaxy s4 just fine oddly enough but still doesn't work with my original shield tablet

So I recalibrated the screen and now my stylus is working again. Will try to repair the sensor and see how that goes, it anyone else has had sensor issues please let me know if there is a software fix of some sort, last resort I will attempt to replace the sensor ribbon.

How to Repair/Change Stylus Sensor?

I googled and couldn't find any information. My CDMA Touch Pro and my CDMA Diamond both have the stylus sensor, however I can't tell if my newly acquired Fuze has one.
With the CDMA Touch pro, you can actually see a little switch that springs out when the stylus is pulled out. The CDMA Diamond's switch is hidden. I looked at the Fuze and I can't see a switch.
Thanks.
My stylus sensor is physically broken. Has anyone replaced this switch before? Know where to get a spare part?
Stylus Sensor
Yes, the Fuze does have a stylus sensor which would explain the ability for it to turn on from stylus removal and ability to launch the notes application during a call. The sensor is somewhat a little switch, remove the stylus from its silo, take a flashlight/led light and shine it into the silo and you will clearly see a little switch, which I believe should be the sensor.
When I remove my stylus during a call, despite that feature being enabled, the notpad never opens. This is what initially led me to wonder if the Fuze has a sensor at all. I guess mine may be broken.
I took a look down the silo and can't see anything that looks like the switch I see in my cdma touch pro or diamond. Can another Fuze user please tell me how far away form the bottom of the phone the switch is located?
NVM, I found it. It's on the right side of the silo wall with the screen facing down about 2 cm in.
It helps if you slide the battery cover off. The switch is located just below where the battery cover meets the case.
The switch breaks very easily. If you've ever forced the stylus into the silo, you've more than likely broken the switch.
Yes, I examined my silo very carefully and I found the spot where the switch is supposed to be, however it seems it has broken off.
Has anyone ever replaced this sensor?
my is broken too. so I bumping tread
Mine broke the evening I first tried my new Raphael.
I remember a very tiny thingie dropped on the floor but when only 30min later I realized that must have been the notch that operates the switch it was gone.
You can send in your Raphael for warranty but I did not do that as I did not find the hassle (phone gne for 3 weeks at least) to weight against the pro's (working switch).
HTC did not want to ship me a spare notch to fiddle in myself 9wich would be te best/cheapest solution for all.
Stylus Lock
This is the stylus lock switch, see red circled in attached picture.
I think its rather very hard to de-solder & re-solder it.
Recently i lost my Touch - Pro ( MB gone) & i am selling working part for helping others.
If you people are interested i can give you the complete IO part & no need to replace switch.

[Q] Touchscreen and Capacitive buttons not working. Good digitizer/screen

Got a couple of spare Shifts lying around that each had a separate problem.
On one the screen wouldnt come on at all, but the digitizer worked. Took it apart and noticed alot of wear on the ribbon. So the screen wont turn on but the digitizer and capacitive buttons register.
On the other the screen came on but the digitizer and capacitive buttons wouldnt respond unless the screen was slightly slid up at the top. So took apart and found the ribbon is actually split across and folded on one side. Funny how it actually worked until I put it back together. Now sliding it doesnt work either.
Tried swapping ribbons on each of the devices, issues remain. I did eventually get the split/folded ribbon to register a touch response ONCE since the swap, but not sure if it just wigged out on me for a minute.
So is there any kind of mix/match thing I can do to try and Frankenstein these phones to work?
FYI: both phones are RUU'd back to stock
To me it seems that both need new flex cables. I think you could just get new flex cables through Amazon. They're about $17 and ship directly from China.
I agree with Chad, it sounds like the Flex Cables are done. You may want to take his advice. But just be forewarned, make sure if you go with Ebay that the seller has good feedback. Also make sure to wear gloves whenever working on Devices, ground the work surface, and yourself. Static is not your friend .
oh dont worry, my shop is quite well equipped for anti-static and safety for both me and the devices i work on ^_^ i have been to ebay and found a worthwhile contributor for flex cables. thanks for the input guys. i still have NO IDEA how the split cable was even functioning. i feel as though if i had never decided to investigate the initial issue i would have been fine.
if anybody would like the two devices in their condition you may make me a small offer. not that im trying to really sell them off as i would like to have them as spares in case for whatever reason my working one decides to crap out and i have extra parts until i do get a flex cable. would be nice to have one on hand anyway. the cable in my current device is perfectly fine, but they do have a tendency to wear out especially since this one is quite used.
the one that originally had the split cable is in beautiful condition with hardly any scuffs or scratches on the digitizer. the other has a fine split on the right side of the digitizer, but it doesnt obscure its use. my current one is cricKet flashed with a similar split on the left of the digitizer. funnily enough it has 3g service but cant make calls or send texts outside of Pinger which is awesome because that means i still have contact outside of my home. it actually had working 4g until i obtained S-Off. now itll connect to 4g but wont actually send or receive any data.
Well keep us posted on how it goes. When you do decide to repair them.

digitizer or LCD screen.

So my photon Q is rather old. Shocking I'm sure. Recently the screen has started behaving very oddly. Flickers, sensitivity is weird, blacks out etc..
I thought perhaps flex ribbon due to keyboard sliding and closing but now I think may be digitizer or the lcd. I"m leaning towards digitizer becasue when it does work it looks perfectly clear. But there will be the one time i push the power to check if I have anything and nothing happens. Reset it and can see the screen wants to do something but can't decide what. Reset over and over and eventually boots up fine.
Digitizer?
Thanks for any info.
Anybody able to chime in
Flickering screen can't have anything to do with the digitizer. The digitizer is just there for input.
It could be that the connector is a bit loose on the mainboard. The way the Photon is designed I wouldn't think it's the ribbon. I could be, but very unlikely. Anyway it's worth looking into the connectors and just to be sure the ribbon as well. But that would take a full dismantle. The connector is just 5 minutes work.
Next time try booting into recovery. If that goes well (and regular boot not) i'm pretty sure it's a hardware problem (GPU).

When boot in any mode Ican't see anything.. A fading circle of grey lines runs vertically down the front. Sometimes after many reboots it fixes itself though. Good to know not digitizer. So take apart and check ribbon and maybe replace LCD likely?
I wonder if it is possible to simply replace the LCD if it's defective or if you have to replace the whole LCD-digitizer-speaker-etc set (which is expensive).

I ordered a replacement lcd screen so will find out. I also ordered the digitizer and flex cable.
So i'm thinking it may be more hardware involved than screen inolved. When it does work everything is usable and it works fine. This is only about 10% of the time at this point. Otherwise it boots up to show some vertical lines traveling down the middle of the screen but only in a circle in the middle of the screen that fades as it gets close to the edges. I'll try taking apart tomorrow night to see if ribbon and what not looks ok. But so far i've invested about $70 into parts and i'm thinkin about just snagging an S5 for $100. I will miss the keyboard though although I can hope that like the s3 and s4, the s5 will get a keyboard attachment. Thoughts?
If I remember correctly the LCD comes with the ribbon and camera connected. The digitizer is connected via a ribbon to a board in the top of the front panel. You could try to disable the pin. When the phone doesn't seem to work, reboot and try calling yourself. If it rings, there's something wrong with the screen and not the phone.
If there was something seriously wrong with the phone, it wouldn't boot. But that's just me guessing/assuming.
My daughter's Photon has had a digitzer replacement twice. And it looks like it's been used to play football. But that one still rocks. No quirks or any strange behavior for that matter.
What I'm trying to say is that the Photon is a decent piece of hardware. A family of four, we all have a Photon. Three of which have had their digitizer replaced and one an LCD (scratched it when replacing digitizer).
I swapped my Razr HD for an Z2. It was time for a new corporate phone. So that, and the camera, is the reason why I went for a Z2. My options were 930/G3/S5/Z2. S5 is not my cup of tea. The G3 has no ruggedness whatsoever. The 930, apart from WP maybe I should have went for it.
So it came down to the Z2. To be honest I'm looking to trade it when the Z3 compact arrives. We'll see.
@Loader009
Digitizer is a part, board for speaker is a part, the speaker itself is a part (adhesive, watch out, btw 100% the same as Droid4), and the LCD is a part on it's own.
Going to open up my phone tonight after work. I was bored and was just playing with the keyboard sliding it open and closed a bunch and now the screen looks perfectly clear.. although sometimes it will still black out and I have to reboot it a few times to get it back. I feel its more a connection inside like you stated earlier. I love my Photon and really don't want to have to get a non slider phone. New phone's are so friggin huge lol.
The good thing is, the PQ has gotten pretty cheap, so you might want to get a used one at ebay if the part to replace is too expensive.
flickering screen (backlight) is not lcd problem.
for 70% is it problem on mainboard - backlight ic. This problem is caused by using unoriginal charger.
and 30% flex problem
I had my screen become un-responsive etc, it was due to a crack in the ribbon. Swapped it out & all ok.
Easier to swap the whole screen assy than to change the ribbon, but depends on what spares you have/can get.
You'd need to have a good look at the ribbon for any damage.

OEM LCD Touchscreen Digitizer Replacement Problem

I have a second generation Shield Tablet K1 that I purchased in December 2015.* The tablet was knocked off a counter and landed face down on travertine tile. The glass/digitizer did remarkably well considering but still had a large crack going down the middle of the screen. The tablet still worked in all regards* and I used it with no issues for 6 weeks. I purchased an NVIDIA SHIELD TABLET P1761W OEM LCD TOUCHSCREEN DIGITIZER on eBay.
I had the new digitizer installed locally at a phone/tablet repair shop. The shop called me and told me the tablet was ready for pickup but there were some issues with certain areas of touch screen not working. Basically the upper half of the touch screen works fine and the lower half does not work at all. As far as I can tell the area that works is exactly 50% of the screen. Just trying to do the basics on it right now is a pain as I have to rotate the tablet 180 degrees every few seconds in order to be able to touch a specific key or an app. Of course the shop won't warranty the work because I didn't buy the digitizer from them. What I'm wondering is if anyone can suggest a specific ribbon wire that may need to be replaced or simply checked to make sure the connection is good on it? Should I replace the touch screen controller?
Any suggestions will be much appreciated.
well, if you don't want to open it up yourself, maybe try getting another, more "able" person to look at it. Check reviews and the company, see if it's a known issue, it just might be a bad buy. I'm bet Ebay will do something about it if you contact them, also try contacting the supplier
I don't mind opening it up. I was hoping for some insight as to what to look for. I can swap out the Touchscreen Controller from my original digitizer and see if that corrects the issue. I thought with such a specific issue (only the upper half of the touchscreen working) someone could tell me yes, with that symptom you need to replace your Touchscreen Controller or that would only happen if XYZ ribbon weren't connected.
Maybe the touch screen is defect?
You're screwed. The repair shop tore the digitizer flex cable. The flex cable has no room to flex on an angle, so the cable just rips.
I just did this myself, and was looking around for a replacement when I found this thread. I couldn't find the problem until after I ripped it more; Now only the top left corner works.
I'm just buying a new one, because the problem I initially opened it to fix needs a heat gun, which I don't have.
Good luck

stylus performance issues

Whenever I use the stylus I have issues with the tip being able to hold a consistent line. Often times the line was will randomly drop in and out; and the screen will only respond to single touch clicks about 75% of the time. Sometimes the screen will create a random. 25" line an opposite direction from where I'm drawing from too. The stylus will perform better when I hold it facing one side vs the other. I've tried replacing the tip on my stylus. This is the 3rd return unit I've received from from T-Mobile and they've all seemed to have stylus issues. Anyone else had similar issues or know a fix?
That sounds like the stylus pen flex. It's an actual part of the LCD assembly meaning you'd have to go with a new screen replacement. I don't know of any other fix for it other than that.
