[Q] Display problem(spot, pressure remains) - Touch Pro, Fuze General

So, few days ago my Touch pro(GSM) started with this weird issue. It looks like a circular spot <1cm diameter. It looks like pressure is applied to the display from back of the display. I tried to take photo when I disassembled phone and tried to resolve this, but display is glossy and camera cannot properly focus :-( spot i located in place where there are hatch(door) mechanism on back. When I dissasembled phone there was nothing causing pressure. I found out that if I press corners on diagonal axis spot disappears. I think that back of the display is arched in some way and pressure on chasis of phone press arched back againts lcd crystals. It happened when I was wearing my TP in jeans pocket. So first thought was that some stich in pocket, or something was presing againts display, but I am almost sure that this is caused by pressure on body of phone. Its night here so I will see tommorow If dissasembling, tinkering with screwdriver helped, but I dont believe this much. Question is: Did someone experienced this kind of issue? How do you resolved it? Will buying new display from ebay help?(I think yes, but there is possibility that display is ok and body is deformed in some way)
Thanks for your time.

Does it look as an oil spot?
Try to raise the membrane with vacuum or sticker and you'll see,if it disappears for a moment.
If so,I am affraid,you have to replace display/digitizer.
I got this oilspot on one of my Himalayas.
Also touch isn't working on this place,anywhere else is working,but after raising the membrane.

Well, I am 100% sure that digitizer is ok, because spot was on display. Touch functionality was ok but display was having strange colors and after disappearing light yellow tint in place of spot. As I took apart my Touch pro, I was ok with buying new display so I looked how old si attached to the case and bended it a little. Spot disappeared and display is still ok and I consider it repaired. Maybe it was really only the bended back or it was one of those self repairing defects.

I think my digtizer has detached slightly

I have this weird issue i have only just noticed. In the middle of my screen, there is almost a perfect rectange of slightly discoloured, rainbowy effect on the screen. It is right in the centre of the screen, and goes to aout 1cm from the edge the whole way round.
Its like the digitizer has detached or pushed up against the screen. I cant remember doing anything to it. And if i run my finger over it, the rainbow effect moves/follows my finger then snaps back to the rectangle (kind of like when you have a bubble under a screen protector).
Also the area under this spot is slightly less sensitive and seems to be giving the odd random input.
Do you rekon this would be covered under warranty? I cant remember doing anything to the screen, and the fact is so pefectly placed in the middle of the screen.
Hey,
Mine does this as well... It's a perfect rectangle, and only visible in strong (especially flourescent) light. Can't notice any differences in input though. Interested to see what people think, and if it's a common problem. Can't remember any incident that could have led to this, I take care of my phone.
In case it helps, it's a UK Vodafone Touch Pro, with the latest HTC WWE ROM.
I have had a similair effect but not a perfect rectangle. somewhere mid screen slightly to the right I had a bubble of rainbow colour. I actually thought it was underneath the screenprotector so i bought a new one to change it. To my surprise the bubble was still there but internally.
I used to have my phone with the protective leather thingy in my jeans. I decided to take it out for a while. And what do you know. after a day the bubble dissapeared. I then put it back in my jeans and checked every hour. The bubble came back. So i'm guessing pressure on the glass internally or something.
Nowadays I dont carry it around in my tight jeans anymore. I use the protective leather that came with it and put it in my jacket pocket instead.
Edit: It has all the attributes xternal listed. The bubble that is.. less responsive random input rainbow following finger. In my case it has been due to pressure on the screen from my tight jeans. Yours might be something else though...
thanks for replies guys, sounds identical to what i have. i thought it was screen protector too, took it off to clean and noticed it was below. wasted blue, i was almost about to edit my post to include exactly what you said about flourescent light.
maybe it has happened from being in my tight jeans, strange that wasted blue and i have the same sized area though.
i have a fuze.
Mine is the Htc Touch Pro from HI, KPN Netherlands.
Xternal i would suggest you don't keep your phone in your jeans for a while and see if the bubble dissapears. Might take a few days at first. just put it in your jacket or something. If it dissapears you know what it is. I don't think this will fall under warranty. if it sticks regardless of pressure you might get warranty...
Oeh i just remember. If the backlight is out you will see a blacker than black dot on the screen where the bubble is supposed to be. if the light goes on its rainbowy fluorecent.
Thanks King, i have taken the protector off and will keep it out of my pocket. The pattern is the same if the backlight is on or off. Id post a photo, but its really hard to get it to show up in a photo.
Im of the opinion now that as you say, the digitizer is pushed against the screen, not detached. Hopefully it pops back
Hey guys.. same issue for a lot of people
It is something like this:

Look at what HTC told me:
New Response From [ Cathy (Malaysia Support (Tech)) ]
Dear xxxx,
We regret to inform you that based on our warranty policy, we can not provide you the free repair on this issue.
If the touch window having some rainbow mark, it is caused by extra force enter to the touch window and it is under user misused. Thus, there is no Warranty Provided.
Thanks.
Best regards.

After some rants:
Thank you for contacting HTC. With reference to your query, we understand you are upset for this issue. But according to the HTC warranty policy, the LCD is not covered by warranty. Please check the attachment for HTC warranty policy. For the "newton rings" issue, we recommend you send it to service center to replace the LCD. Thanks.

Thanks for the help guys, I'll try keeping it out of my jeans pocket for a while. Sounds like this "newton ring" problem in the other therads though. I'd tried replacing the screen protector as well before, but no joy there. Might need to try to get a replacement (took out insurance on it), but guess I'd need to flash back to the carrier ROM.
Anybody know how good Vodafone UK's insurance is about newton rings?
Just read kingpinda's post again, when my backlight is off I can still see the rings, so doesn't sound like the same problem. I'll still try it though, thanks.

I fixed the rainbow rectangle digitizer issue with duct tape!

Long time lurker here... I got the dreaded "rainbow" rectangle on my screen that meant that the digitizer stopped working. I was pretty sad to say the least. I called Verizon and they wanted $95 to send me a new one with the silly insurance plan. I scouted google and saw that many other have had this issue.
So, I broke down and bought the replacement digitizer on eBay. Well tonight, as I looked at my broken phone, I thought that since I was going to be eventually replacing the digitizer, it couldn't hurt to try to mess with it a little. I noticed that the rectangle appears as a thin film between the top and bottom layers of the digitizer. This thin film is what causes the rainbow effect, just like a thin film of oil on top of water.
What got me thinking was that I had just set the screen to beep when tapped, and every time I turned it on it tapped once. This meant that the screen was actually being pressed continually. So, I thought that I'd try to pull the screen away from the bottom a little. I finally got some duct tape (of the clear variety), and carefully laid it over the entire screen. Then, I pulled off at a pretty shallow angle so it would pull on the top layer pretty good.
Well, lo and behold, the screen started working again! And there isn't a hint of rainbow/oilness at all. And it is totally responsive, as before.
So, if you are in the same boat, try some duct tape or similar.
Cheers!

That's pretty good news I suppose, at least one possible DIY solution has been discovered. Kinda puts my mind at ease thinking that one day my phone might not be responsive to touch. I'll have to keep this in mind if that day ever comes. It does make sense though.
Be careful doing this. It fixed my spot, but now the LCD only displays 2 white lines.

New LCD+digitizer problem

Hi,
I have just replaced LCD and digitizer of my HTC raph (first time) and there seems to be some kind of problem. It turns on, but the screen shows nothing just lights up a little bit and there are some stripes visible as if the lcd would be broken, but it's brand new. The stripes changes a bit as i press some buttons or touch the screen so the phone and touchscreen are working - the problem is with LCD.
I don't know if i put all the conducting tape to the places it originaly was. Could that be a problem? I double checked all the connections but still, might be a contacts problem?
Any thoughts on what might cause this?
Also the phone got kind of hot after having it charged for some time, is that normal?
Of course, this may be caused by a bad connection (but rather hard to go wrong slot), but at a distance hard to say something more concrete.
Best to check with the new flex.
Thank you for the answer, i will try changing the main flex.
The flex cables can touch eachother right? Since they're originally covered with conductive tape.
BTW, i also intend to change the lcd + digitizer... my question is:
how to apply the digitzier? lcd and digitizer came separated - do i have to solder/glue or whatever the flex (of lcd & digi.)?
The original was something like sticked together... reminds me on sellotape aka Scotch Tape.
Can you give me a some help?
thanks
The ribbons must be solded together, there's 4 contacts on them and they should not touch eachother.

Verizon Galaxy S III (i535) Display colors wrong after glass replacement

To make a long story short, my wife dropped her Samsung Galaxy S3 i535 phone a couple weeks ago and shattered the front glass. I ordered the replacement glass on eBay and proceeded to get it installed this past week.
One of the things I noticed was that none of the repair videos adequately documented how to route and attach the button for the home keys at the bottom of the screen. I was finally able to get the old home button ribbon cable detached from the phone and pulled free from its location. I noticed that there was still quite a bit of adhesive left on the resting location for the home key pc board (located a few mm in front of the ribbon cable that connects to the lcd assembly.)
I made the mistake of thinking that the adhesive consisted of some form of double sided tape, so using a small blade and a pair of forceps I began removing the adhesive. Turns out, the adhesive was attached to a felt-like material that was covering the back of the LCD. Once removed, I noticed that the section of the screen from which the felt had been removed was slightly discolored.
I proceeded to reassemble the phone with the new glass, and it is working correctly, with one exception:
The entire screen (not just the area where the felt was removed) appears to have a greenish tint to it. This is most notable when booting the phone. The SAMSUNG logo appears as almost a neon green (My wife assures me this should be white) and the booting animation is mostly green (She assures me it was multicolored)
A couple of questions here:
Did the piece of material I removed from the back of the LCD cause this problem, or should I be looking at something else for a solution?
Is there any chance this felt-like material contained the backlighting for the LCD Screen?
If not, could just a small section of missing felt allow enough light to escape to discolor the entire screen?
Also, since I obviously can't replace the felt, would coating the expose area with some form of paint or something work to restore the proper coloring to the phone?
I am currently looking at other replacement lcd assemblies which, from what I can tell, simply involve moving the motherboard from the old phone into the new assembly, connecting it, then putting the back cover onto the phone. If I can afford spending the $100-150 that these cost, I would like to avoid it. If this is my only suitable solution at this time, I would like a definitive answer so that I can make the purchase and get her phone back to working order.
Thank You all for taking the time to read my post, I can post pictures later to elaborate on what I am describing, but my wife and I are both at work at the moment and I don't currently have her phone to take a photo of.
Pictures would be nice. However your back light shouldn't discolor your screen. My guess is you loosed a cable or something else causing the screen to discolor.

I will get pictures posted this afternoon. After taking a little more time to look at it earlier today, it appears that Green and Blue colors are working, I just haven't got any red.
Do you know where to find a diagram of what ribbon connectors control what aspect of the phone?

A little late, but here are the pictures of my wife's Galaxy S III (i535)

that will give you an idea of the connector for the screen. you say all you did was replace the glass? not the whole screen? I cant imagine how this would happen unless you damaged the ribbon cable when removing the glass.
unless you want to remove the glass again you'll have to take it apart from the rear, which isn't too hard really. take the back cover off, then remove all the little screws you see. that piece of plastic will come off and this is what you'll get: http://imgur.com/WwoOgMP
the red box is the connector, make sure it's seated. i'm not sure you can get all the way to the digitizer panel from the rear, but this is simple enough it's worth trying before removing the glass again.
also there are plenty of youtube videos on how to teardown the sgs3.
on a side note, task killers are bad for your phone.... use Greenify instead, or nothing at all.

If this ribbon cable that connects to the LCD was damaged, it might be your problem.
In that case, you will need another LCD.
It's best to buy the LCD and Glass as one piece.
About $120 or more.

Strangest screen problem I've ever seen. Would this be a broken displayor broken GPU?

Hi all
My moto Maxx has gone through a lot, but the strangest problem yet started yesterday.
As you can see on the attached video, half of the screen is constantly scrolling. This happens in fastboot and recovery mode as well, so I'm pretty sure it's a hardware problem.
The digitizer still works perfectly, and registers touch where the icon or button should be positioned on the screen. The moving screen also does show everything correctly, just in this crazy scrolling way.
I'm not very hopeful in fixing it, but was wondering if anyone has ever seen this, and if you guys think this is a broken display(and any way to test this?) or a broken GPU. If it is in fact the display, I might consider replacing it.
Some background on all the terrible things I did to this phone:
- Dropped it and cracked screen in September.
- Replaced the glass myself, slightly burned display when removing glass without any consequences (just a tiny mark on the top right, the side that actually still works).
- Dropped again, broke glass again, never bothered to fix it, some small pieces are missing so dust, sweat,.. could've gotten int.
Video:
Most likely the display being broken.
Even when my tempered glass protector is missing chunks the screen starts to funk up. Only worse being the real screen especially the digitizer.
You might be right pjd, or at least screen related.
I opened it up yesterday evening, and I think it might be the cable connecting the screen. Depending on how I positioned the screen and thus the angle at which the cable was bent, it was fixed, the same, or just completely black.
The only thing I have to try to find out now is if it's the kabel, or the connector on the motherboard. Any suggestions on how I could test that are welcome!
