Replacement screen/digitizer - MTCD Android Head Units General

Well I'm done with this crap screen I guess the ribbon cable is pinched or cracked somewhere I cant see, I've taken the glass off and inspected the ribbon cables but I cant find it so I'm in need of a new one.
Its the intel sofia quad1 r16. If anyone knows the part # and a place to order from in Canada or the US rather than china that would be awesome :good:
Thank You

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

Change LCD Cable

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!

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!

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

Need Lock Bar/Clamp for LCD connector

I have Galaxy SM-P600 (2014 edition) which was the victim of poor repair at local shop... Now back has popped off and since the tech(???) did not glue down screen and it slipped and locking bar on mother board connector for LDC connector was damaged and popped out of "connector" and lost....
My question is where can I get replacement "lock bar" ... Rest of table is fine, just no screen becasue of no clamp bar on LCD connector...
Or is there a repair that may be not official but workable?
Dale M.
Hello Dale,
What you want is LCD´s FPC conector lock, and that´s hard to find.. Made a quick search on aliexpress, but couldn´t find it. I have bought lots of fpc connector from this seller , contact them, maybe they have what you want, but unlisted.
There´s an ugly repair you can do, but require good soldering skills: You can solder lcd flex directly to main board, not a task for begginers. I have seen some connectors like yours "fixed" with duct tape, it seems to work for a while.
Thank you for the reply... Looking closer, one pin on motherboard part of connector is damaged so I would guess its toast.... Unless I can get another motherboard, but that doesn't seem practical... The cost of this it ridiculous as it was $550 (purchase price) to begin with and I have another $235 after the first accident, now this..... Think I may just have to walk away from this...
Again thank you...
Dale
Just looking for a used or bad motherboard on ebay, then remove the connector and solder it to yours. It requires skills and equipment to this re work.
May be just look for another mainboard, depending on luck, I see someone list the used one for over $100.

usually beggining and end pins are ground, so it shouldn´t be a problem. just need a multimeter to check it out. if you spent $235, I guess you had to replace LCD. take it to the guy that made the mess, and tell him to work it out.
It is not going back to that person.... Bought a new one, I like the tab so well, and was trying to salvage this one....
Might watch for 32k machine with broken screen and maybe get something going, but for now its a basket case....
Originally I was going to do screen repair myself, now I wished I had...

Here is an used motherboard, you can replace it by yourself . I can take out the motherboard within 5 minutes as it has only 3 screws on two speakers to hold it.
http://www.ebay.com/itm/SAMSUNG-GAL...-07719A-USA-/331575405067?hash=item4d336f2a0b
Or this one, a completed tablet with flickering screen, this problem can fix easily by re solder the battery connector. You can use the motherboard and keep extra parts like LCD asssembly. An used LCD assembly can sell for $150 easily.

Thank you for that information...

Not good, I'm pretty sure the tablet has a clear optic adhesive under the digitizer glass and lcd so if you remove the glass the glue will be remove too and you will be left with a display that looks like it has a big air bubble under the screen...(someone correct me if I'm wrong)
see the thread here (for the 12.2 model but I'm pretty sure it's the same for the 8.4)
http://forum.xda-developers.com/gal...p/replace-cracked-glass-tab-pro-12-2-t3251203
so you will most likely have to replace the digitizer glass+ lcd in one unit
for the full assembly you might be able to find these on ebay or aliexpress (china- might be official or knockoffs)
http://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20160117213008&SearchText=sm-t320+lcd
look for ones that include the LCD + Digitizer as one (usually around $100-$170) - also make sure the store has a good return policy and good feedback (maybe even good feedback for the item aswell), it is very hard to return to china so it's best to make sure before purchasing.
http://www.samsungparts.com/Products/Parts_and_Accessories/SMT320/Default.aspx
this place sells all the parts but you might need to email them to get specific part numbers - and well it's probably expensive
last but not least send it to Samsung and have them fix it, they will usually just swap out the lcd + digitizer with a new one.

Thank you. I guess its too expensive to make a screen replacement for the tab. Not really worth it to fix it for $200. Rather than buy a new tab. Hopefully i can find somwhere else where they charged not that much. Thanks again.

I would check around with local repair shops (ones that specialize in tablet and phone repairs- since they should be very familiar with the oca film), maybe if you can supply them with a replacement digitizer, they can do the rest of the repair for cheaper.
you can check youtube for the oca film process (type oca film or LOCA screen) and a bunch of videos will come up.

It's crazy, this tablet costs more now used than what I bought it new for.
I too have a broken digitizer... And my screen has been going bad.. So unless you live near a samsung service center, that option is out. I keep seeing people suggest the LCD + digitizer replacement, but there is not one guide on how to actually do it.
The only thing I could find was some German guy on YouTube for a digitizer (not a whole LCD) replacement. How do you go about doing the replacement? The generic answer has been look at iFixIt or YouTube, but there isn't anything for this model...

I broke my digitizer the same week I got mine. I found only one place online to buy one. Google it, it's from China. It was about $160.00ish.. I followed the tutorial for galaxy tab s on YouTube. It was very easy.
