Sorry to start up a SAD SDA topic but it has to be done...
I thought I'd be smart and pick up a broken screen "tornado" SDA from Ebay like some of us have already done. Got it, hooked up to usb cables and my activesync 4.5 picked it right up, allowing me to explore the file system and even browse some naughty pics (oops) that the previous owners had left on there. Ok, seemed to work, could make a phone call with my sim card etc...even without being able to see past the cracked LCD screen.
Next step was to buy a replacement screen, for which I am sure you all have seen the "2125 screen" that is the exact model as a Tmobile LCD. I replaced this and prayed for the best.
The best didn't happen. I got a nasty all white screen and got upset....then recheced the ribbon cable connections and they were appropriately installed.
Same thing over and over. WTF?
I have SOTI pocket controller professional. For those who don't know what this is, it allows remote viewing of the little screen on your PPC phone or Smartphone on your Desktop or Laptop computer's monitor.
It is great for the purpose of checking functionality of a "broken LCD" phone. Everything worked fine on the virtual screen! I even UNLOCKED and SUPER CIDed the darn thing and have reflashed original OS from TMO just to be sure.
WHY ON GOD's green earth can I not get a working display on this thing UNLESS of course, I got ripped off by the ebay vendor. (who never sent me a replacement envelope as promised to swap out and send this one back)
Just venting but seriously, DOES anyone have a solution.
It is not a dead phone, bricked, wrong operating system, or any of the other posited theories here. The screen is just inexplicably white and properly connected. HELP.
Thanks.
I am an MDA owner and just dabble in this SDA thing.
I would love this nice little phone to work..if not, I have a brand new housing, a possibly working screeen (with another phone) and lots of parts for someone..hint hint.

Hey mate, don't loose your faith!!! Redo the connection. The same thing happend to me, and I swore I had pluged that flat connector correctly into the socket and I didn't. Wiggle it, you can't enter it straight in, it has to slide in on an angle. Look at the one you removed. Look at the mark left by the "YELLOW TAPE" that holds the ribbon inside the slot. It will tell you how far in it has to go. Also, there are 2 other contacts that have to be in the propper position. One makes contact between the back plate of the LCD and a mesh looking spot where it sits. It has to sit in place so you have the "ground" on the LCD. If you need, I can put apart my phone and take a close picture and post it for you so you can see what Im talking about. But I'm pretty sure that your problem is just the ribbon not being in all the way. There are 2 sets of connections inside the socket. If the ribbon isn't all the way in, only the 1rst set will make contact, LCD will light up, but, no image. Good Luck and I do hope its as I say. Please let me know here or on PM if you need some pictures.

Thank you for this insightful and confident reply!
I am certain that it will be quite useful to a Tornado user with this problem in general. The screen I got must be defective (too late to return) because this advice above should be the perfect solution.
Didn't work for me though but It is very nice for someone to put the effort into posting in such a manner.
Kudos to a valuable member of our community!
I might fool around and pick up another used T-mobile SDA and pray that I can get one working properly. If this screen works on that one, I guess I bought an ebay dud (masked by the broken screen).
Yes, this phone is getting dated but I really wanted to experiment with new ROMS and push it as far as it could go.

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.

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

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

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.
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!
PS: Ening, did you get to solve your issue?
much sad

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!

Hi, i gave the phones to a guy in a repair shop and he looked at it through a magnifying glass
agnobi, I have exactly the same problem, but tested several digitizers and same problem
see my post here : http://forum.xda-developers.com/moto-g/help/black-screen-backlight-ok-screen-t2803431

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 ).

very interesting your experience ...
the strange thing is that we are several persons to have the same problem and the same symptoms ...:silly:
I've unsnapped the connector as they said in the video of etradesupply...

I've also reflashed a stock ROM ... no change
so it's not software/firmware related ...
so it's hardware
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 :>
I have a huge scratch down my screen and the local mobile repairing guy quoted £55 to replace.. I thought this was a bit steep.. I expect him to use real gorrila glass 3 @ that price
Sent from my XT1032 using XDA Free mobile app
finally I've just fix my digitizer
It was 1 or 2 pin twisted on the right so there wasn't a contact between the PCB and the patch....
denseye I think your black screen can be fixed, you may see the pin on the left...." Bon courage " PM me if you have questions....
I've got now my earpiece which crackle but I thinks I'll not try to fix it....
Good night
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.
(Yeah I'm french and i've sent you a MP.... "Dur dur le correcteur ortho ...")
Hey All,
I recently dropped my nexus 5, however there is no screen damage, there is still damage to be noticed. On the screen itself, there are numerous vertical lines, disallowing me from actually using the phone. I've been able to connect a USB OTG mouse and connect to my chromecast which works fine.
Again, the screen itself has to visible physical damage. Could the GPU be broken? I'm really confused.

I think you broke the LCD panel (/liquid crystal)l behind the front glass, that's why you don't see any damage on the screen.

Thank you for the response. So would I need to do an entire digitizer + Lcd replacement costing me around $100ish? And would that fix the issue?
Your actual gpu/image processing works since u were able to use it on chromecast.
Since it was a drop there are a number of things that could have gone wrong . In order from cheap to expensive it's flex cable , lcd , motherboard. The fact that you can use screencast , and the lack of touchscreen response could mean the screen is broken and not the mainboard. But again could.
If you could get a temporary replacement screen for test you could diagnose it and see if you keep the screen/buy one or scrap the phone.
Thank you everyone for the responses!
