cables that fragil and are mainly a plastic with either a conductive paint or copper cladding is not a repairable thing other then replacement, a few have suggested searching ebay as you can get a replacement screen cheap this may also apply to getting the cable only if it's detachable. but believe me I've tried this and i'm great with surface mount on the PCB direct soldering on the ribbon is possible but the wire type adn tools needed out weigh the cost of the LCD used or new
Hi there!
While replacing the speakre of my BA the lcd cable broke. But I already changed the lcd some time ago and now i have one broken lcd with a good cable and one good lcd with a broken cable.
Does anyone know how i change the cable?
Sorry friend, I had made the the same mistake; there's no way to replace it.
You have to buy a new BA lcd screen.
Well....
Some of those ribbon cables are attached to the glass via what amounts to glue. Electrical contact is done just by touch (no soldering).
At this point, I'd take apart one of the LCD's to see. It's not like you are going to make things worse if you break the glass on the dodgy LCD, it's already dead, correct?
Just try to post the results so the rest of us know as well!
yeah please post your results...
better if you have pics for it.
... im interested in "frankensteining" our BA's

The best price I've seen for the touchscreen is on ebay. But, there are a few catches...
First issue: There are two different LCD/touchscreen assemblies that were used on the angel. One is made by Sony, the other by Toppoly. The touchscreen or LCD from one can not be used on the other due to programming and physical layout.
Second issue (and this is probably the biggest): The way they touch screen and the LCD are connected is a major pain in the arse to fix. It's a plastic ribbon cable that has been soldered to a point on another ribbon cable. Unless you are very good at soldering, it's not something I'd attempt due to the largish chance of melting the cables and making things worse, not to mention the potential to hurt the LCD itself.
If you look in the wiki under the hacks and tweaks, the Technical Stuff (including disassembly) link has two pages to look at:
Blue Angel/PPC6600 Disassembling Procedure with Pictures
Blue Angel Spare Screen
While they are not the best pictures, the last image under the disassembling section shows the ribbon cables I'm referring to, and the touchscreen assembly picture for the spare screen page shows a sony touchscreen ribbon cable detached from the LCD cable, which will show the connection points I'm referring to.
I've got this exact issue as well on my O2 branded angel. Due to the cost of a new LCD/touchscreen assembly (almost the cost of a working angel), I'm considering trying to solder a new touchscreen. If I ruin it, well, I've got parts for the next one I get.
I replaced a touch sreen today, its not that bad if you have soldered before. Unfortunatly the screen i got of ebay is not perfect and will need replacing. I have contacted the seller to see if he will send me another one.
Its worth doing!

I've soldered plenty of times (a bit out of practice tho), but never something like that.
Any tips and suggestions? My main worry is melting the ribbon cables.
Well, no real tips, just take you time and don't rush it. The plastic can stand quite a bit of heat, i never managed to melt it, The job looks harder that it realy is. you will need a steady hand! Also , taping the connector down before you solder helps.

Ok, that's good to know. The plastic didn't look all that durable, but if it's stouter than it looks, I may check with the house controller (aka CFO aka my wife ) and see if we can spare the dosh to pick one up.
I have to be careful as she wants it once it's fixed!
how do i separate touch screen and lcd? i only need to solder the new touch screen, right?

There is a disassembly guide in the wiki.
What kind of screwdrivers are needed to remove those tiny screws on the LCD/ digitizer casing. I have 2 SX66's with broken LCDs and one with a broken digitizer. Time for some repairs.

Hey MATE!! damn why didnt i ask this before!!!
i have the o2 xda IIs.. same problem, display works fine.. but tapping doesnt! after it was dropped!
Now, i got a guy to get a spare MDA T-mobile (blueangel) which doesnt work, but its lcd/touchscreen works.. i connected that LCD to my O2, it didnt WORK! how can i differentiate b/w the two LCDS?
i mean, how can i know that the LCD is made by Toppoly or Sony?! that'd be a great HELP!

Part numbers on the back or the cable design.

this is the code written behind my LCD. I have the O2 XDA IIs.
Is there anything else I need to look at aswell? or should I just buy a LCD with that code?!

Interesting. Looks like the LCD used varies depending on when the phone was made.
My O2 has the Sony LCD.

Cables and the wiki. The link I posted shows the difference between the two.
And yes, you will have to get the same LCD assembly/glass cover as what you have now. The two are not interchangeable.
There is a tool set you can purchase at radioshack that has the proper tip. Its a cheaply made tool but does the job. It is one of the kits with many bits. It would be the star tip. You can also order the tool online. I've taken mine apart a few times. Its sort of a pain but gets easier the more times you do it (replaced my screen three times). I have however, never been able to get the touch to work again because I can't really see how I would be able to solder such a fine ribbon. Ive had my mogul for almost a year and if my memory serves me the metallic strips are only about an 1/8th of an inch thick or less. I got lazy and put a piece of tape across the ribbon and put a small amount of glue to hold it down. Still didnt work. Didn't really expect it to either, but it was worth a shot. I turned it into insurance said I lost it and ended up with a broken 6600 and when I called to complain they sent me a mogul. So it's been awhile but I loved the phone. Hope this helps out.
dont scare the people
it can be replaced in 15 minutes with proper tools (screwdrivers)
i ve found some russian manual with pictures how to disasemble the BA (just look for it on the net) and its very easy, no need for soldering
there are 2 versions of displays, one have silver ribbon and the other have golden
when you opet your BA you ll see the display and the ribbon, also there is serial number of the display so you can check it too... all BA displays on the ebay have info about the ribbon and the serial number
I bought it for about 30$ and works perfectly, as original one...
buy digitizer and screen in one piece
you have to be total noob to have problems with changing of the display, so go for it !
If you are planning to replace the digitiser YES you do need to some fine soldering, all you need is the correct soldering iron tip for fine soldering and it is possible, done it about 4 times so far and everytime I promise myself not to brake it again but hahaha,
You can buy the LCD + digitiser together if you are unable to do soldering,
I use a razor which i took out from my shaver and thats what I use to seperate digitiser from lcd.
There are very cheap digitiser panels on EBAY, However some of these are not so good and ( digitiser is a 2 layer glass assy.) sometimes little area of this 2 layers stick together making touch screen non responsive.
Alternative is look out for spares, repairs sales if the screen is good buy it replace it, if you are a novice when it comes to these things, just take your time and dont rush it, even if it helps make little notes when you are opning the device as it ll make it easy when it comes to puting it back together.
And if you can get your hands on one keep a spare screen
Im sooo sad
I just cracked my screen I really hope I get a replacement cus I got more attached to my BA ever since I found out I could upgrade it. I thought it was not a biggie crashing it because I have dropped so many times and nothing happened but today something happened...
screen is 30$ at ebay, and no need to be sad, in few days it can be fixed
Ok, so the phone turns on, LCD screen even flickers on once in a while, it won't stay on though. And everything looks just how I left it. So I'm assuming the mother board is good, the LCD is bad/fried and the digitizer glass is ok. Would that be a safe assumption?
Now, I had two other Incredibles, one with a cracked LCD, one with a cracked digitizer. Swapped out the digitizer and as long as we put the right mother board in that went with the LCD, it worked great. So I'm assuming I can't just go buy an incredible off ebay with a cracked digitizer and swap out LCD screens? And will a "New" LCD replacement screen work? Thanks!

I don't see why another LCD screen wouldn't work, but it's really hard to say with this kind of thing without just trying it, which is what people want to avoid because throwing parts at it costs money. Its not necessarily true that the motherboard on the device is ok. Its certainly possible that it could be fried, but in a way that allows power to still get to the LCD but not control it properly. Another option would be, since you will be taking it apart anyway, inspect the motherboard or other circuitry if you can see it and look for burn marks on the board that would indicate a short circuit. You can't always see them, but it would tell you if it were bad if you can see it.
Hello everyone, So I recently bought a Nexus 7(2013) about two months ago, It's a great device and for $229 I can't go wrong with it.
But recently I was using it for reading a book in bed and it dropped from the side of my bed (about a 2 feet drop) I picked it up and to my surprise there was a hairline crack at the lower right edge of the screen and most parts of the screen are not responding to touch but there aren't any flaws with the display . I went to ebay and checked replacements, I saw two different things an LCD screen(about $40) and a digitizer(about $20), There are also LCD+Digitizers for about $60. What I want to know is should I replace the digitizer or the LCD or both? also are they easy enough to do by myself or should I leave it to an expert? Thanks in advance
Seems like it's just the digitizer. A broken LCD wouldn't display properly.

So should I order just the digitizer? cause those are a lot cheaper than the combos
I wouldn't do that. The glass is glued down and is almost impossible to remove without breaking the LCD. Lots of work with a heatgun or hairdryer and trying to cram plastic cards in between to get them loose. It is very stressful on the parts. Best to buy the entire unit and put your broken one on ebay. I've broken two similar units this way.
