[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.

Xoom no backlight?!?!

Hi all out there,
My xoom has no backlight? in some angle I'm able to see what's on my home screen, but it's all dark, totally unable to work around...
Someone know something about that? You guys around here are my only help. I have no warranty, cause I bought it from US and I'm i Europe....
Greets,
Philip

Interesting, this person here have the same issue http://forum.xda-developers.com/showthread.php?t=1767082
Hmm I still don't think it's a software sided issue but a hardware issue. You could open your XOOM and if there is anything wrong with the connectors, but you will properly have to replace the whole LCD screen. I had a few LCD TV fail on me before and it's generally the back-light that goes first, so it's not that surprising. Hmm another problem is I looked on ebay over here and a new LCD screen or touch digitizer actually costs more than what it's worth.

The ultimate Nexus 4 digitizer failure thread

I've been using this phone for around 14 months now. I've always thought about how LG managed to build a phone like this and sell it for 300 bucks. Well two days ago I got the answer. The lower part of my screen just stopped functioning, thus disabling my buttons. I searched for this problem and found a MASSIVE thread on google support forums about this. Basically the lower part of the digitizer just goes full retard. Sometimes it works, sometimes it doesn't. And when it doesn't work it makes the entire phone lag (on a custom rom)(it doesn't work 95% of the time).
To fix this i tried to make the navbar slightly bigger, but that resulted in a growth of the defected part. And using PIE or button saviour is just a pain for me.
I made this thread to let people know that this problem exists. If the next Nexus phone is made by LG, I'm buying something else.
This is an open discussion, so anyone with a similar problem/fix can post.

I really dont know, what you guys actually do with your phones. I am using my nexus 4 for about 1 and a half year now, has been dropped twice with two scratches on the edges - no screen broken, no bootloop ever, no nothing. I can say of myself that I am not the friend of bumpers or screen protectors or any of those ugly things. I also flash a lot, try out a lot of apps - my nexus 4 has seen it all.
But not only the nexus 4, also my previous phones are fine and they still work (a nokia 5130 xpress music and a sony ericsson u10i). Thats why I thing a phone is just as good/stable/great as the user do. Of course there are a lot of issues out there but I think they dont appear from nowhere.

4 nexus 4's in the family most almost 2 years old......never a problem. This kind of crap reminds me of the " my back glass just exploded on its own" thread. Let's not make blanket statements.....digitizers on phones malfunction all the time....on all brands, probably due to your mistreatment.

I do not understand the point of blaming it on the user though. Yeah, many phones from different brand have digitizer issues. Yeah, digitizers fail. But if a lot (and I mean a lot) of users are complaining on the same exact issue there is a manufacturing problem for sure. And it's pretty clear that you did not bother checking the related thread at google's support forum, otherwise you would notice how many "mistreating", as you say, users are all having the same digitizer issues in exactly the same part of the screen. Now, does that mean that every nexus 4 sold will have the digitizer fail at some point or another? absolutely not. Maybe its' only one every 100, or even 1.000 or 10.000. Maybe it was a defect of a relatively small batch of screens (seems legit since the issue always occurs after a certain amount of months), that were sold in a period where you didn't buy the your four statistically (ir)relevant devices.
when will you guys understand that just because your phone does not have the issue, doesn't mean that NO phone has that issue??
(and even if it's not one but 5, 10 phones, how much relevance do you think it has compared to the hundreds of thousands of shipped devices?)
for what matters to the actual thread, anyway, I read LG replaces the defective devices under warranty without fuss. If the device is out of warranty, a diy repair is pretty easy to people savvy with tools.
Anyway, there is a couple threads here that talk about the issue:
http://forum.xda-developers.com/nexus-4/help/q-t2810588
http://forum.xda-developers.com/nexus-4/help/screen-touch-test-results-t2822075

This isn't the users' fault. Take a look at this: https://productforums.google.com/forum/m/#!topic/nexus/7SNIT8xPYzc
The repair costs in Sweden are so high, I might aswell get a new phone. I didn't even get this phone for 350$, LG sells it for 500$ in non-google play countries. And btw, half of my screen is not working now.

Or maybe you spent the last year keeping your phone in your pocket instead of a belt case and damaged it, or dropped it, or got water on it, or any of the other 10 million things that could damage an LCD/ digi. While I understand you have a problem and are looking for someone to blame....99% of these issues are due to physically caused damage and not defects. I have 2 teenagers.....I know how they treat their phones and I spend a lot of time repairing them after " I didn't do anything"

Same here
I'm having the exact same digitizer problem with my Nexus 4. First, a band of 8mm at the bottom of my screen became unresponsive, then a week later, the band grew to about 14mm.
I've had my N4 for 15 months. Bar two hairline cracks on the back panel (around the rear camera and speaker) my phone is mint. Barely a scratch on the digitizer front panel, and yet, it's failing. The weirdest part is, the otherwise lifeless zone at bottom of my screen occasionally springs into action with erratic ghost touches on my nav bar. I'm working around the problem at the moment, however, if the dead zone gets any higher, my phone will become unusable.
Reddit, YouTube and Google support are full of similar occurrences, and still not a peep from Google or LG.

My wife and I both have been using nexus 4 phones since it launched nearly two years ago. Hers started doing this 3 months ago and is practically unusable now. Mine started doing it last month and is getting worse too. I always thought of it as a great device and thought highly of LG's build quality but its hard to have those feelings now. Seems related to age + heat. Will be trying a different manufacturer next time since her phone has always been in a case and is flawless. Mine is banged up bad without a case but lasted longer.

Also my 16 monts old N4 two weeks ago after a run in hot humid weater followed by a very long phone call started to show problems at the bottom of the screen (no swipe up to activate Google Now) and in a couple of days all the lower portion of the touch became unresposive as clearly showed activating the pointer position under the developer options menu. Does anybody know exactly where is the problem? Digitizer connector, synaptics chip, cable? At present I'm trying to convince Google UK to issue an RMA in Italy where I'm now and would appreciate hints how to achieve that as it seems they offer RMA only to a country where the Nexus 4 was originally available on the local Play Store.

back glass does crack on some phones when there is sudden change in temperature ,it happened on xperia z as well dont be so naive , the probability of mistreatment has nothing to do with factory defects

My digitizer works fine until the batter gets to about 80% .... then the screen freaks out and the phone turns off.... fun stuff!

Ya right....ignorance......

This is actual real problem. My Nexus 4 works fine. But replaced the digitizer on my brother's after the bottom half died. Just go on eBay and buy the panel for around 50 bucks. About an hour of work

repaired my screen
i replaced the screen after just 1yr 7 days. I live in India so phones available are quite cheap and the screen replacement cost was cost of an average smartphone but still i replaced it . I just want to know whether the replacement screen will have a digitizer problem after 1yr. I also had to replace the battery.

4 Screens replaced, the last 2 had bad digitizers?
I've replaced cracked screens 4 times now... the 3rd developed issues with the touchscreen going unresponsive every once in a while (I would tear down the phone again and again and finally the touchscreen would inexplicably begin working again.) I Finally cracked that one and now the new one has the same issue. I installed the new screen/digitizer, again with some difficulty , After a few reboots for whatever reason, suddenly unresponsive. Reboot 4 more times and it's back. Initially I'd thought I just bought a bad replacement screen but two in a row is pointing me towards .. well, something else...
Looking closely at the new component I'm a bit concerned as the text on the ribbon cable from the digitizer is labeled "Snaptics" rather than "Synaptics" though the chip itself is labeled correctly...
Sigh...
In any event, I was hoping someone could possibly shed some light onto this. 4 screens later I'm a bit sentimental and would hate to have to retire my N4.

I almost replaced my screen assembly because I had the dreaded dead band in the middle of my screen. It was present in TWRP so I figured the digitizer was bad. Then I started to get screen jitters and ghost touches. I tried wiping everything, new ROM's, etc. I final flashed the last PA KitKat beta and the 4.4 Gapps. Problem solved. I re-flashed the PA 5.0.2 Alpha 2 and there are no problems anymore. I was convinced it was a hardware problem because the problem mirrored every N4 digitizer problem thread that I saw.

Samsung galaxy s4 "lcd" screen replacement

Hi, im the owner of a Samsung Galaxy S4, and yesterday I broke the LCD Screen , but all the other functions work, like the little notification light, etc. The shop I normally go to charge me 150C$ to repair the screen,m and I tought it was a bit excesive considering I can buy replacement kit off Ebay for like 80C$. I wanted to have your feedback on my idea to do it myself and also I'm having trouble finding the right screen. I have a SGH-M919V a canadian model and I didn't see any screen specific to that model, only M919 screen, so does it gonna work if I put an M919 lcd screen on my M919V ?
Thank you !

It's sadly annoying to change the screen on galaxy S phones. You have to start from the back and basically tear the entire phone down.
There is a guide on ifixit for tearing it down but these kits im seeing on ebay for 75 seem to be ones that need glued in since they aren't the entire display assembly. I would look over that guide and see if your comfortable with that sort of stuff. It may be worth it for you to just pay the 150 vs potentially messing your phone up in the process. The other option is sell the phone and get a S5/S6 or some other upgrade?

Alright, thank you for your help and your quick answer ! I'm still in reflexion about all this, but you certainly help the process.
Thank you again !

Actually, I find the s4 to be very easy to take apart. I have repalced the screens on 4 phones with no problem.
If you buy a replacement screen, make sure you get a pre-assembled frame/lcd/glass unit. It's easy to damage the frame when you remove it from the old screen and having the frame pre-installed is not too much more than the cost of the lcd/glass.

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.

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.

Replacement screens usually look rubbish and have ghost touches in the digitalizer

Thank you for the suggestions.

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.
