Replacement touch screen?

Hi all,
my tg01 has a large rainbow patch on the screen, and it is sometimes visable even when the back light is on,
i was wondering if replacing the screen would solve this problem?
and if this is the solution is this the right part i should order?

The part you have linked to is just the Digitiser (incidentaly not apparently identical to the TG01) - the resistive matrix pad which sits over the actual LCD and provides the 'touch' x-y grid information to the processor.
A rainbow patch suggests one of three things:
1. a point of pressure which is distorting the LCD screen under the digitiser
2. possibly a crack in the actual glass
3. inward distortion in the digitiser causing it to press against the LCD glass
I'd look closely first to see if you have anything eg. between the battery and the body which might be causing such pressure forwards; then check the digitiser to see if the surface appears bowed inwards and finally examine closely for any crack.
It may be that a new digitiser would solve; but if there is a crack in the LCD glass then I'm afraid only a replacement screen will solve.
Good luck !

Thanks for your help
i will look into it more
but i think its because of the screen being exposed to a point of pressure because lately i have been keeping it in my trouser pocket along side my ipod which i think has created the rainbow patch

I found something like this.

maybe it helps

alternative solution
If someone in Italy have broken his TG01 and want to sell, i'm online, my tg 01 need a new mainboard....
Thanks

why not try

Finally, you buy it?

stay away!

I think we can try

I will ask a very stupid question... can I put some other device touch screen or like to put REGZA the tg03 capacitive screen? u dont need drivers for that just that screen fits?

Most unlikely that it would be practicable to transplant a capacitive screen. The resistive digitiser on the TG01 screen has a dedicated ribbon cable interfacing to the main board providing X-Y information; even if the capacitive substitute had a similar connector, the hardware on the main board will not be able to interpret the signal. And I am sure that there will be different drivers for the capacitive screen, even though performing the same function.
I would have to ask though why the desire to go capacitive ? The resistive screen (properly calibrated) gives virtualy the same responsiveness with the massive added bonus of being able to use a proper stylus when wanted, in particular for real handwriting recognition, which is impossible on a capacitive device.

just asking, I had and capacitive that was really bad so as resistive and I had the good capacitive and probably the best resistive screen here on tg01

[Q] HTC Hd2 TouchScreen doesn't work + black screen

Hello...I have an HTC Hd2 ,but the touchscreen doesn't work...Yesterday the display works fine but now,after i disassemblyed the phone,the screen is black,but the LED-s are lighting. In some positions ,LCD works fine...
My HTC has the touchscreen with soldering version
The question is: the soldering of touchscren, can affect the LCD? If the touchscreen is missing,LCD is working?
Sorry for my english! Thank you so much!

1-YES, AFFECT LCD of course
2-maybe... it depends, they has an independent connections
3-WTF?¿?¿?why you dismount your device??????its possible that you crashed the electronic contacts....(OMG)

I cleaned the digitizer contacts and lcd contacts and for 5 minutes it's work perfectly...
I hope LCD is not broken,or his flex cable...
If the touchscreen doesen'twork,should i buy a new one? Or it's another problem?
Thanks

lcd goes with the touchscreen by default......(50-60euros more or less)...
why you don´t try to disasemble it agin and scroll the problem?you don´t loose anything...

I will go to a GSM service and i will say to service man to disassembly the phone and to clean the contacts,and to say what is the problem!
I hope LCD is not broken ...only digitizer.
Digitizer can be responsable for black screen?

I want more opinions...
I repeat...Digitizer can make LCD Black? LCD is black but the led's are working
Thank's.

Change Sensation display (LCD) by One S display (AMOLED)

Hello,
I like Sensation but screen consumption seems high (as in all phones)...
I saw that HTC One S has the same resolution and the same size screen as the Sensation, but AMOLED.
Anyone know which pinouts have each screen module?
Because they are similar phones, maybe have same screens (pinouts).
If not i whould make small changes (if pinout are same but in different order).
I hope display driver (chipset) are included in the LCD module, not in the motherboard ...
I think about buy HTC One S screen on ebay when available (now dont have) and try to change it ...
(im not sure about sub-forum of this post... y think "sensation accesories" fits better than Q&A because Q&A posts are doubts about software, not hardware... if another sub-forum are good please move to them..)

I wouldn't do it. The One S screen would recieve a current it's not supposed to.

because different voltages and currents of the tft screen i need driver/chipset in screen board.
If driver are in screen board, flex cable that connect to motherboard takes digital signal bus and may be the same in both screens.
For example: there are many laptop screens that uses different lcd panels (with different control and backlight voltages), but all of them have same connection: dvi mod (now).

why not just buy the one s if your gonna be dropping cash on a screen for one.

This is a good idea, if this works. I'll be down to actually do the mod as well.

so.. when sold htc one s?... i think now, but y doesnt find anything about this and his replacement parts...

Any moderator would move thread to
http://forum.xda-developers.com/forumdisplay.php?f=1425 (hardware hacking).
I think is more apropiate... (if think "no" dont move xD)

Just to add the complexities that danirebollo mentioned, another big issue is that the mainboard might be a totally different layout. You might have to do a custom cable. Also, the thickness/thinness of the panel might be an issue.
IMHO, it would be cheaper to sell your Sensation and purchase a One S instead of modifying & purchasing a new panel.

90% of phone screens are not compatible with each other. If you find two that do, it's a coincident rather than the norm. And if I were to go through so much trouble as to source a replacement qHD Super AMOLED screen, which I'm sure won't be cheap to being with, I'd just get a new phone.

if that is possible, count me in, ive bin looking into it ever since i switched over from the samsung vibrant, but never really made any brake throughs

Agreed, I tried to upgrade the SoC by putting my R1 engine in it last night, and would you believe it, it didn't fit. Unbelievable. I wrote HTC a very strong letter of complaint ; )
Sorry, it's that time of the day here in the UK where my silly side rears its head.
Would be a good mod if it worked but I doubt it very much for the reasons mentioned, plus, is the didgitiser bonded to the screen in this new generation of HTC phones?

Well as far as I know, the only way to change the screen on one of these is to change the entire motherboard with it, I found this out at somewhere is the desire thread because many of he desire phones had smiled screens but then Samsung couldn't produce them fast enough and switched it for slcd but people wanted amoled so they swapped it all. Maybe if we asked HTC about being able to swap the screens ( yes it sounds stupid bit what else can we do?). Although the chances are amazingly thin we could request it from them that if you send the phone with them align with the cost of the amoled screen, they should replace it or even ****ing tell us how or if it can be friggin done. Power comes through numbers.....

Yeah, if someone finish this work, I maybe have a try

lol?? why sooo sarcasm??
some phones have same lcd screen (no digitizer), it hasnt rare idea... the only problem was different tecnology (LCD->OLED) but normally the only important was control bus, i2c, (i dont think these screens need this bus), and video data...
i dont know now if it is possible until i have both pinouts.

The other problem I would think is that the touch screen driver wouldn't work with the new screen

I have spoken to my manager regarding this and unfortunately we cannot advise any customer to change there device specification or hardware as this will void the warranty of the handset. I then went on to ask if our repair centre can perform this, unfortunately we cannot request this as this then support customization of the devices which is against the device terms and conditions..
I do apologise about this however we are unable to perform this request.
This is what I got from HTC asking if:
a) if it could be done.
b) if they could do it for us if we payed.
So I'm guessing somebody will have to try it on their own first. GOOD LUCK and God's speed.

Another problem,
I upgraded manually a Nexus S i9023 (slcd, like sensation) with android 4.0.3 leaked pakage in december. This package was made for i9020 (super amoled version): Android run beautifully but when you go into recovery you can't see anything (if you use a very bright light you can barely see the text of the recovery) cause it has drivers for amoled screen.
I suppose that if the screen change is possible you could also have problems to see recovery that is made with normal sensation's screen driver, imho.

If this ever works, it will end like Motorola's Cliq multi touch patch. While it might work, the screen voltage sensors won't be calibrate correctly and will end burning the screen (if you don't believe me Google it). The same could happen to the screen in general, with wrong voltage its going to break.

How to fix a not working touchscreen (Tinji i9300)

Hi,
Could you please help me on how can we fix broken touchscreens? I'm using Tinji (Tianji i9300 s3 clone) mt6577 phone. My Einstien brain managed to cut the flex cable to touchscreen and its now not responding at all. I'm using Tinji i9300 mt6577 chinese phone.
Initially, the screen did not respond on the right and left wing where I was struggling to even unlock it.. Thought of opening the cell and reassembling it myself looking at various forums feedbacks mentioned here. I opened the cell apart but before I could realize that the flex connection touchscreen, I already had broken it and now the touchscreen does not respond at all. Dead as stone!!
Is there a way to fix it. Request your help plz. Thanks.

buy a new one. those digitizers are not that expensive and getting a new one is easier than soldering a flex cable. trust me, i tried it myself on a cannoo.

Thanks Chrizz,
Phew!! atleast I have someone hearing me on these forums.. Thanks a ton for your reply..
Request you to please guide me from where do we get these digitizers? are they screen specific as in 4.7 inch or CPU specific as in mt6577 specific? Or will normal digitizer work? Thanks.

Help
Good evening,
I have same problem with my i9300 Tianji, you can tell how you solved your problem.
If you bought a touch screen where you purchased

[Q] Digitizer not working after reassembly

Hi everyone.
So i tried to replace the cracked screen in a Moto G (I just replaced the display+digitizer+glass module). After the reassembly everything worked except for the digitizer (it worked before when i tested it). I tried to reconnect the digitizer connector (the tiny one which connects the digitizer controller to the display connector ) multiple times, but nothing worked. Has anyone faced a similar problem before?

Hi, I have exactly the same problem.
In my case, it's my second screen, so I've already eliminated the screen+digitizer and the cable connector like the origin of the problem.
Has anyone any idea?
Thanks!

Bad news. My digitizer cable is damaged. On both original phone and the donor. I was not careful enough: the closer inspection showed it. I am going to order another screen or a donor phone (like a used verizon one or something) and try it again.
So the thing is that the video on etradesupply shows it wrong. You have to unstick the tape covering the digitizer cable connector, then unsnap the clicky thing, and only after that should you unplug the screen master cable (the one that goes into your PCB). Otherwise, it is very easy to damage the touchscreen controller cable (the digitizer one).
I really hope you have a different problem and there is still hope for your phone :crying:

Hi Ening,
How do you check the veracity of the cable connector failure? I think I have the same problem than you, but I haven't a way to check it 100%, because I haven't anyone who can lend other screen to me, and the original screen it's now completely destroyed.
I suppose that I will have to send back the screen to the seller and ask for another.
Thanks anyway!

The flex cable part that connects the controller to the rest of the cable is very thin and easy to damage, you've to be very careful or you're gonna screw it (like the OP did).
ofcourse there is a slight possibility that it came defective, but you should have checked it right when it arrived. So far I haven't seen any incomparable ones, but who knows.....

I think there is something else.
On my side, the 3 digitizers (old one + 2 new) give me same result.
The I think the problem should be on the mainboard or a hardware/software blocking ... or maybe something we didn't re-assemble well
and little question : what is the role of this part (see my photo) ???

Probably the last :>
That thin metal plate makes connections on the back of the PCB (its mounted right between the display and the PCB) and I think it connects to mass.I got no idea what it's role is (prolly its a fitting or some sort of heatspreader).I've assembled one phone without it and it worked just fine, but I've put it back afterwards, just for the sake of being complete

and your digitizer works fine ?
I think also that the issue comes from the connection PCB-patch or as you said software digitizer blocking.
So I 'll try to flash a retail rom to see it .... ...... The digitizer still not working

I've replaced 9 digitizers on 9 different moto g's.None of em had any kind of these problems.This leads me to the conclusion that you've done something wrong.
The worst I had is 1 dead pixel on one of the new displays ( I'm using digitizer+display+frame assembly ).

Never, all worked the first time and afaik they are still working fine.Gotta mention that the ones I`ve used are chinise ones, but look and feel like the original, even the glass feels like gorilla glass 3, altough I don't believe that's the case :>

You mean a pin on the pcb connector where thé LCD câble goes? (Français???)

A pin means a spindle which links the patch(LCD câble) to the PCB.There are many pins which compose thé connector.
