Droid Touchscreen Not Working - Motorola Droid and Milestone General

Hello,
I recently took apart an original Motorola Droid just to see what it looked like inside, and to indulge my friend's curiosity (since it's technically her phone). Since I did that, the touchscreen no longer works at all. (which she's not wild about, though thankfully she does have another phone).
The glass on the screen is cracked, but the display assembly itself is fine. I made sure to put all of the connectors back in their right places, and even took the phone apart again to make sure that everything is assembled correctly.
Does anyone have any insights or thoughts on how to get the touchscreen working again? (Please? So my friend doesn't kill me?)

Hardware Problem What do I replace

I recently purchased some housing and screens for 3 Tilts I am planning on putting up on ebay. The phone with the problem was my original tilt that was sent back for a warranty repair but in transit the carrier ran it over with a truck or something. It came back with tire marks on the package. Needless to say this caused some trouble with the ATT warranty people. After it sat in my garage for a year I pulled it out.
Every thing seems to work now except for the touch on the screen. I know it is not the screen itself ( I installed it in another phone and it works). I have hard reset flashed and taken it apart various times. Nothing.
The new symptom is that i found out if I push really hard on the buttons on the front of the phone I can get the touch function to work for a second or two.
I want to know what part should I be buying. Do I need to buy the whole ribbon connector that twists itself from the front of the phone to the back or am I missing something else all together.

Possible Ribbon Problems

My Xperia X1 is currently experiencing problems. The screen no longer lights up!
I started experiencing this problem a while ago, when opening and closing the device.
Day by day everything went from bad to worse and at one point it no longer lit up!
At first I thought there was some kind of screen problem so I bought one new LCD off ebay.
I disassembled my Xperia carefully following a tutorial on youtube.com and replaced the screen. Nothing changed. The screen didn't light up.
The strange thing is that everything else worked! Sound, buttons, vibration etc. all work without a glitch.
I had gave up my hopes of reviving my device and for four long months it simply got dusty. That is, until I found this post :

I opened my device and realised that I have the same problems mentioned in that post.
Thus, in an attempt to solve the issues I opened my phone and took the following pictures.
Please can anybody confirm that I have flex ribbon issues and tell me what I can do to solve this problem once and for all? Can I fix it or do I need a new Xperia flex ribbon?
I can't wait to start using my 'old' device again!
Look like a flex ribbon issue to me. You can fix it by getting a flex ribbon of course. I've had 3 go out on me...thinking about giving up on this phone entirely.
As mentioned in the previous thread re: similar problem, the flex will always be the culprit in any device with slide or flip form factor, not limited to Xperia. Most of the repairs coming in are for flex damage, regardless of the device price and quality.
I had no issues with replaced flexes on Xperia, once installed they serve their life span (albeit short one). It is possible to reinforce the flex, provided your tape is a very fine one, it needs to run in particular place only, e.g. where it is physically rubbed and bent the most.

HD7 Display Replacement

Hello all, I just replaced a broken LCD and digitizer on my HD7 with a unit bought from eBay. It's from a supplier that I've used very frequently, so I trust the component. When I got the phone back together, it will sometimes boot, sometimes not. It will also sometimes display just fine, and other times it looks like it's garbled, or just not display at all. The screen will be blank and not react. I'm pretty versed at repairing phones, I've probably done 30 for myself and friends, so I'm pretty good at reassembly. Is anyone familiar with this issue and can maybe give me some ideas? Cause I'm flat out of them.
The other thing is that when I start moving the phone around after reassembly, this is when I start experiencing troubles. I tried putting electrical tape in places under the mobo to keep from grounding something out, but it doesn't seem to help. Any ideas would be great.
Did you put on gloves when you were doing the replacement. Cause like you I have done alot of screen replacements on a wide range of phones and I would have to say that there are devices out there were if something got grounded out while you are doing the replacement it tends to start doing all kinds of goofy things once the phone is back together. I have found that by wearing "gloves that do not conduct electricity" the chances of something like that happening is gone. Ive only had two devices do weird and strange things like some of what you have said. These were some of my first repairs and after changing to putting gloves on I haven't had a problem since.
Hope that helps and also I am about to replace the screen on a HD7 that I just bought just wanting for the screen so, I will let you know what happens.
Thanks, probably good advice. I've been very lax about using grounding protection of any kind. I've seen those guys who use the "finger condoms" where the rest of their hand is open. Couldn't hurt to use a grounding strap too, pretty cheap and easy precaution. The other thing I noticed about the phone was the SD that came with it isn't recognized by any OS, so wondering if there wasn't something else wrong with the phone.

[Q] Milestone digitizer replaced, but new one has problem with "calibration"

[Q] Milestone digitizer replaced, but new one has problem with "calibration"
Hi!
I got a two year old Milestone on which the digitizer started to act up a while ago, with random clicks (seems to be referred to as "ghost" clicks) and touches everywhere, pretty unusable. After buying a new digitizer on ebay and replacing the old one, all those problems are now gone!
However, I do still have touch problems. It seems a few percent of the top and the bottom is unreachable. Input is registered, but at the wrong location. The bottom "buttons" (which is via digitizer as well?) works fine however!
A video of it says it all:
ht tp://ww w.youtube.com/watch?v=YNGcpAMPfUQ
(added some spaces to get around spam filter)
To me, this looks like some kind of calibration error... Not sure if that is applicable though.. Cannot find any kind of references to this on either this forum nor anywhere else.
Now, I've tried the following:
* Going back to stock firmware
* Clean CM7 (which is what I used before)
* Wiping all caches & resetting everything
Nothing seems to help. I can not find any calibration tools or anything either..
Any hints?
Thank you!

While waiting for a re-shipped item from the ebay seller (paid extra shipping only), the digitizer magically started to work again!
Not really sure how or why, but after leaving it powered up but idle for almost a week, the upper part of the digitizer was fully functional! The lower part was however still non-functional exactly like the video shows.
For some reason I got the idea that all this was somehow heat related; it had been lying in a relatively warm, closed off room during this period. So, I put the lower, still non-working, half of the digitizer (still powered on) a few centimeters below a regular desk lamp, applying some heat to it. I left it like this for an hour, and when I pulled it out, it was working flawlessly! Has now been working fine for ~2 weeks.
Just thought I'd post this here in case anyone else has the same problem.. There has to be some kind of manufacturing problem with this one, not being glued together properly or something.. At least I got an extra digitizer now as spare, in case this one gives up again

[Q] SIM not read after screen replacement

As we all know, the phone is pretty darn well put together and surprisingly durable. But, unfortunately, it is not invincible. About a month and a half ago I cracked my screen. The phone had a case, but it wasn't anything hefty (the HTC Double Dip case). The phone was still completely usable, but I like the phone and wanted to keep it nice so I decided to replace the screen. I ordered the screen + framework assembly and it was about $55. In the past when I have replaced screens on a few iPhones and an ASUS tablet the parts were quite a bit cheaper, but whatever. My phone is the black model, but I decided to try something different and ordered the new part with red speaker grills. Most guides and such said that the M7 is a pretty hard phone to repair, but I have worked on a couple other phones before, so I gave it a go. After many, many hours of carefully prying apart the phone and transplanting the logic boards to the new screen framework I put it all back together and powered it up. To my surprise the phone powered up and the screen worked fine. (And let me tell you the red and black looks damn good). The first thing I noticed was that vibration didn't work. A bit annoying, but the phone looked good enough that I could get past that. Next I tested the speakers and noticed that at full volume the speakers sound a little bit messed up. Again, a little annoying, but I'm not a professional so I wasn't overly disappointed. Then came the real problem...
THE REAL PROBLEM:
When I put the SIM card in the phone didn't detect it. After a reboot it still didn't detect it. After a factory restore it still didn't detect it. Perhaps the ribbon cable connecting the SIM reader to the board was not all the way secured? After how hard it was to take the phone apart the first time I was not a fan of the idea of doing it again. But alas, the next day I opened the phone back up super carefully so not to damage the new parts. It was thankfully a little bit easier the second time. I made sure the SIM reader was all the way connected, but the phone still wouldn't read the SIM. I pulled the old SIM reader out from the old screen framework assembly and plugged it into the board, but the SIM was still not detected, indicating that the new screen did not come with a bad SIM reader. Has this problem happened to anyone else? What steps should I take? I now have really nice looking M7 that is essentially useless.
So does anyone have input on this?

Click to expand...
Click to collapse
Same thing happened to me. Also swapped out the old reader without any luck.... Any update on this?
Does it detect it at all? Like ask for the pin code if you use that?
Do you have to disconnect the battery when replacing the screen on this phone? I know on some phones I repaired I had to manually set the current time and date (resets to year 1970 or something like that if you disconnect the battery) to get a signal.
Otherwise I have no idea
