[Q] TF101 backlight out

Two days ago, my TF101 appeared to stop coming on. However, after looking into it further, it appears that only the backlight is out. Does anyone have any experience with replacing these?? Also, if I send this to Asus to get it repaired (it's a refurb, therefore not under warranty) then do you have any idea how much getting just the backlight replaced will cost?

Brand new lcd screen with backlight is available for $64.99 + $9.78 shipping at Ebay. Should be easy to replace, just have to be patient and careful. If you do it right, you'll save money and have a fully working 101 again. Good luck!

Here's a video of the disassembly to get you started:

Do you know how to replace the screen? I've replaced about 1000 laptop LCDs so I know how that is done. Do you know of a video of this being done or a step by step guide with pictures?

I have also done screen replacement on laptops but not on any tablet. However, the only difference between the two is the added touch screen digitizer which is integrated with the glass so the assembly consists of the lcd and the touchscreen digitizer. They can be purchased separately or as a one piece unit which will set you back for $175. The lcd alone is $65 and the touchscreen is $80.
Youtube has several videos on screen replacement for tablets like the Toshiba Thrive but I have not seen one for the TF101. However, these screens should be similar in design and construction so you may get an idea how the lcd and touchpad components are put together. Good luck!

Do you see anything on screen but there is no backlight?
I have the same if I set more than about 60% of brightness. I have to get it lower, lock and unlock TF and everything is "normal".

Tried that, no luck. I'm guessing I'm going to order the LCD screen and give it a go.

Question about HD2 screen and digitizer change

Hello,
i cracked my HD2 screen (digitizer), i purchased new one, but the cracked one was working and i was not in a hurry to change it. After a minor drop, the LCD touch screen cracked under the cracked digitizer and now i have black screen...
Now also i have to purchase LCD screen, but i saw that there is ready to use screen+digitizer(and of course more expensive than screen and digitizer alone) .
My question is - what will be easier to change - ready to use digitizer + screen, screen and digitizer alone or there is no difference. I'm asking this, because I'm wondering should i sell the digitizer (if i can) and buy the ready to use screen+digitizer, or to purchase the screen and to use it with the already received digitizer.

If you can afford it you have to go with the all in one. Too much can go wrong during assembly and you should avoid it if you can.

yup, separating and installing them separately is a pain in the arse, its always better to do it in the one job if you can afford the initial high cost. My LCD panel needs replaced due to light bleeding, but I cant be arsed, the digitiser is likely to fail in the future anyway being an HD2 so ill wait and just do the two of them together.

OK, thank you.
I've watched 2 or 3 "how to change digitizer" videos. Is there a video for changing the lcd+digitizer or its the same as the digitizer change? I have to disassemble the whole phone to change the digitizer...

there is a vid somewhere, ill have a look later, but essentially yes. you need to remove the whole lot, the only difference between doing them both and doing them separately is that the two panels are stuck to each other, and its that process of separating or putting back together that's really tricky and people have ended up damaging one or the other trying it.

What about the difference in the EU and T-Mobile versions, like in the digitizer (soldering and insertion) Is there a difference too, if i take the whole "pack" (LCD + Digitizer) and what should i look for if there is a difference?

If you buy combo(LCD+digitizer) there's no problem to replace it to whatever version of HD2 you own: combo is interchangeable on both versions!

OK, Thank you!
I'm asking because i asked some buyers on ebay, and they told me "Sorry, my friend, but this is for T-mobile version" But on the pictures, they are all the same.

I had my EU hd2 digitizer changed too when it was broken, and when it was changed to a tmous replacement, they couldn't get the promixity sensor working.
Now I dunno if that's a defect from the screen or because it's a incompatility problem, but a further gsensor-working-in-wm6-but-not-in-android-problem in my other replacement mashup hd2 hybrid EUTMOUS frankenstein phone suggests that some parts may not be interchangeable.
You should just make sure that it's a EU digitizer so you won't run into further problems.

But on a already assembled combo pack (LCD + digitizer) how to know if the digitizer is EU version, beside the T-mobile logo.

I doubt it's a relationship between digitizer and g-sensor/proximity sensor...

Let me clarify that; my hd2 EU first had its digitizer+LCD replaced with a TMOUS version, and the proximity sensor stopped working,
then the the mobo was replaced by a tmous mobo in the same EU housing and the accelerometer and magnetometer does not work properly (accelerometer works in wm6.5 but not android), but the proximity sensor worked.
It's not just me having a hardware replacement problem, there's a significant amount of posts by other users about replacement parts not working properly. So everyone should be at least very cautious about using them because replacing with other parts may cause other problems.

my buddys HD2's touch screen suddenly stopped working.
he gave me the phone for $50.
i guess ima have to do lil work

I need some help with choosing the combo
Which one should i take and why on one the second item there are those big cable-like things.
N1 - http://www.ebay.com/itm/LCD-and-DIG...ccessories&hash=item43adebdc7d#ht_3076wt_1110
N2 - http://www.ebay.com/itm/NEW-lcd-Tou...ltDomain_0&hash=item3a67e44659#ht_2175wt_1344
Will i need to solder them together or they are already soldered (welded junction or whatever)
Thank you!

Anybody?

Both versions are OK, but I would choose the first one.
There's no need for soldering(vers. 2): it's more like a packaging thing in order to get it mounted on chassis.

I guess its because you/they lost the little glasses that connect the display and the sensor.
Its easy to loose them as they fall out after you take the screen from the housing.
I lost them a few seconds ago and think that i know what wont work when i reassemble
@topic
there is generally no problem removing display from touchscrren. just make it hot with a fan or oven ~80°C is okay. and with a flat knive or iron-wire go for the glue.
If you do this you need new glue-tape. Mostly you get this from china very cheap but takes a while.
If your screen is broken now i would recommend to take a combi pack as you have no glueing, no alignment problems and so on.
its not very hard but kills some time and nerves ;D

OK, so lets do a round up, before i make the purcahse, so I'm sure i will make the right choice.
I'm going to buy this one http://www.ebay.com/itm/LCD-and-DIG...ccessories&hash=item43adebdc7d#ht_3076wt_1110
because its already assembled and much easier to use and IT WILL FIX on my EU version of the phone (Not US T-Mobile)
Only YES or NO will be enough

The Eu-HD2 is soldered isnt it? This version, from the picture, is the pluged version....
Im not sure because if you change the display also the connector type could be irrelevant.
But if this is the screen from Tmous-HD2, i remember that it was a bit bigger? Is it just the housing or also the display?
=>
Dont buy before this is clear!
(i would open my hd2, look what connector type is inside and buy that one just to be sure...)
And some advise: Try to glue the flex cable from the touchscreen(the one that goes under the end call button reallly close to the display)
This could help to improve the life-span of the cable as its not flexed every time you push the button(try when you hold it in your hands by putting the buttons in the frame and push it, if it flexes the cable fix that!!!)
Otherwise the cable will break one day and the wires will disconnect=> typical problem of not responding touchscreen

My screen cracked with a part of it not responding to the touch. which replacement sc

hello
my nexus 7's screen cracked after just 4 days of light use .. and now I have a triangular area in the top right of my screen that's not responding to the touch so that now I can't get to the right notification area unless rotate the screen or use a mouse . so I was thinking of replacing it.
since I live in Egypt and I had the tablet shipped to me from the US my only option is getting a screen shipped from ebay and installing it myself. so I was wondering what kind of screen should I get to get the whole touch screen working again.
i've been looking on ebay and was wondering if something like this might work?
http://item.mobileweb.ebay.com/view...1082526272&index=1&nav=SEARCH&nid=34354766081
I am not a very technical person so I am sure what the digitizer is.but I am guessing it's the part that broke to make the screen unresponsive.
so . should I get this one? if not what should I get?
I am looking for something cheap since the shipping cost is a lot.
thanks in advance

just upping the thread. I need the answer desperately

With screen + shipping + labour charge (to change screen).. Isn't it better if you get a new set and sell off the broken one on eBay? At least it's a new set and problem free.

a new replacement screen costs as much as a new Nexus 7. I cracked mine in January. The only way to use it is to connect a mouse which is pretty lame. Waiting for the newer Nexus 7.

since I live in Egypt. I can't really sell stuff on eBay. and my nexus 7 is the 3G version so I can't afford getting a new one.
I am really confused about the concept of a touch screen, a digitizer and an LCD. what is the differences between them and what do I really need?
if you can help me with eBay links I would much appreciate it.
thanks in advance

There is a guide here on how to change the screen (ok it seems I can't post the link because don't have enough posts. If you go to ifixit and search for nexus 7, there is a guide there)
The touchscreen part (digitizer) is the outer glass.
The LCD is bonded to the glass.
I've only ever seen the lcd and digitizer sold together. It is a lot easier to change them as one unit instead of trying to remove the broken digitizer from the lcd.
As people have said the price of the part outweighs the cost of fixing it, but if you really wanted to do it you should find all the information above.

lg g2 screen replacement worth it?

My phone screen is damaged and from the official store the cost is 150 euro to replace the screen/frame/digitizer with a new one.I have followed a youtube video to disassembly my phone and now i am wandering.
Should i go and grab a new screen/digitizer/frame from ebay with 40 -50euro?Have anyone here tried it?

Work perfect for me.
*LG G2 D802 D805 Black Screen Touch Digitizer & LCD Display Replacement Part
US $42.55*
I replace it 2 month ago by myself.
Remember that you must to use Film Protector Cover It may not gorilla glass.

Honestly after doing it several times due to defects with the screens I bought, I got to know my phone a lot more intimately than imagined.
The skills picked up along the way will go far.
Here's my thread detailing my experience with this.
One takeaway I can provide is:
Do as much research as you can up front. Be sure to be in contact with the seller you buy your screen from. Not all screens are the same

My seller was 6389team or something like that. Just make sure whichever screen you buy, ask them all the questions you need to know re: quality up front.
Also confirm they have the correct version before you buy.
Post your results in the thread and do the poll so we can keep track of your results as well

After doing over 5+ G2 screen replacements..........I vote a self-fix.
Its a relative easy phone to work on.........nothing is overly complicated in the layout of the frame and phone.
The only major thing...........is the type of sealant or double sided tape you use.
I used Loctite High Performance RTV silicone on my first few times (messy process, but can be less if diligent)
I used a spool of some cheap double sided tape on the last few replacements.
Both ways have there pros and cons..........but both got the job done for me
I would recommend researching the proper adhesive though...........I just used the RTV, because I work on car related things so much and had a full tube laying around from a speaker cone repair.
There not a lot of information on screen to frame adhesive......most discussion is about what UV adhesive to use if seperating LCD from Digitizer.
I ALWAYS say get the LCD Assembly (lcd glass/digitizer already fused complete to install)
Here is the video I used when I first started: https://www.youtube.com/watch?v=sqzgD490avg&index=2&list=LLd8QZ4c1aksnO69EHHC4_TA
After doing it a couple times.....its all by memory now.

Some folks on my LCD replacement vs OEM screen quality thread claim their screens without logo are identical copies to the original. I wouldn't rule them out completely without trying it.

Screen cracked for no reason

I'm seating at my desk with my phone on my side over the mousepad and after hearing a very faint "pop" sound I notice there is a very clean single crack running from the top to the bottom of the screen. The phone was bought a month ago, never dropped, and it was not even being touched when it cracked. What could be the reason? Some type or thermal stress or just a manufacturing defect?
At the moment I'm living in a country without official Xiaomi support (Japan), is there anything I can do about it?
I'm quite surprised by what happened and I have never heard of a screen on a new phone cracking for no apparent reason.
Pictures:
imgur .com/a/Q5Lon

I once put a Sony MP3 player at the window, in winter. At the morning it was cracked. I gotowe beating from my dad for breaking the christmas gify a dat after receiving it. Still wish these days came back though.

It's probably a manufacturing defect. Where did you buy the phone? You could try explaining the situation, but I think it would be a huge hassle, just take your loss and spend $30 on a new display.

I need only the digitizer, the LCD itself looks fine. Would it still not work well? I have never replaced a digitizer (or a screen) by myself, but on such a cheap phone I may as well try. Or is it an almost impossible task and I should just replace the whole screen assembly?
Also,isn't there a software setting for calibrating the digitizer? Using it can't I get the original performance?

I bought a €20 full hd screen for my Ascend P7 and it looked the same as the original. $30 is a normal price for a phone LCD, only OLED displays are much more expensive (another reason to avoid OLED screens on phones)

Not recommended, you save maybe 20$, but you still risk breaking your screen and having to wait another 3 weeks on a new one.
