I've got a broken nexus 7 that I tore down after the screen shattered with a good motherboard... Is there anything I can do with it? Any possibility of outputting to a screen?

You might be able to check the wiring to the screen on the nexus and see if the wire leads match any of the know configurations of other video sources and possible hard wire it into another video source. You might have to change the resolution to match the screen you use though. Anyway, you will still have to use a keyboard and mouse.
You could scour the internet to see if the LCD panel & digitizer can be purchased somewhere. But possibly that might cost half as much as a replacement.
You could sell it on eBay as a "broken - for parts" listing.
You could see if Asus will quote a repair for you.
If everything still operates normally as far as the USB port & physical buttons are concerned (it still operates correctly as far as software is concerned), donate it to a dev who wants to try cracking APX mode on the N7; either that or become that dev yourself! I suppose there are folks who are willing to try, but don't want to put their own unit at risk of hard-bricking.
Well that's 4 suggestions. Sorry to hear about your device.
Mine shattered too and I took the battery out. Will use it for my replacement (which I got the N73G) if the battery ever dies.
Sorry for your loss.

You didn't mention if the LCD broke as well.
If the LCD is still working, just use a USB mouse with the device.
Otherwise, if the LCD is no good, part-out the unit.
Look to ebay for avg asking prices for various modules.
As for the MoBo, since this system was really designed to be touch-centric, unless you can really create a new ROM for the unit that doesn't rely on touch (the Ubuntu ROM maybe?) it's uses are limited.
With the Ubuntu ROM you might be able to turn it into a web/media/file server. But then again, it may not start up if it can't find all the peripherals it thinks should be attached.

I rather recently received this chinese tablet, and unfortunately whilst charging the tablet it stopped powering on and working period, so I took it apart and salvaged the working parts. I am inquiring about the name of the screen connector and the touch surface connector. I have attached images of them both below.
Anyone?
Anyone? please?
Anything written on the back of the screen which may help?

Nope just empy space my best guess would be a C or D sized ribbon cable but im not sure and If I can learn the pin out I can just wire it up to a VGA or the likes the touch screen is another story I also need to know how much power this thing runs on because Im sure ive got the resources to power it.
The main thing is getting the LCD controller: is there some chip or PCB somewhere on (or inside maybe?) the housing of LCD display? If not, you'll find the chip on the tablet's mainboard, and by searching for it's name, you might find a complete controller with VGA/S-Video/Composite/RGB input (something that's supported by controller), and you hook up the display there.
Simpler way, how I'd do it, would be to look up for the datasheet of chip on the Google, and then wire the inputs according to pinout in datasheet.
It might take time to find out how to power it up and how to feed it with image, but in the end it should work - currently I'm working on a same thing, but with LCD taken from portable DVD player with controller in the LCD housing.
It seems to have the controller on the accessory board, I will try to look for the data sheets like you said, thank you so much

Your post is asking for the name of those 2 connectors? They are called flexible ribbon cable, easy to break and imo not really flexible at all, cause they break.
Can't remember how many of those buggers I broke over the years.

Just the information I needed thank you!
So...I just died a little inside...
What I've foolishly done is dropped my Nexus 7 screen side down onto floorboards and as you can see in the attached picture...something has gone awry. I'm assuming that it's the digitiser that's broken??? - is there anything I can (relatively) easily do with limited knowledge of this kind of stuff (via tutorials?)? Or would I be best replacing the device? When the screen is on, the individual bars change colour, cycling through purple, black, but mostly white. The tablet makes the unlocking sound and I can VERY faintly see some aspects of my home screen.
Any help would be appreciated. Rotten start to the new year.
Located in Melbourne, Australia, if that's of any use...
you could check out Tablet repair shops on Craiglist . They usually fix cell phones and tablets for 10 to 40 bucks. Its worth it.
if you are good with tools you could pop it open your self and see if any cables are messed up, give you a better idea on what you need to replace

I try to repair anything I can, Its usually cheaper and also a good chance to gain experience with this stuff. I cant tell you how many screens ive had to replace on my wifes Iphone haha. As far as tutorials go youtube has a whole bunch of them some are more thorough then others Heres a good one to get ya started. Nexus 7 Tear Down
Here is a written tutorial for removing the screen assembly. Between these two you should have no problems! Nexus 7 screen repair
If it still has warranty, you can copy everything you need off the SD card and get it replaced. You can try sending it to a repair shop, but it might be cheaper to buy a new one.
called asus and they told me that it'll cost $220 to replace the device as they won't repair it. I've copied everything over to my pc and I'll probably have a crack at giving it a tear down and fixing it. otherwise I think I'll upgrade to the 32gb as I've found 16gb to be too restrictive. annoying (for me) that there will be a new model in ~6 months time...

just completed the tear down - my battery took ages to remove due to an insane amount of glue (yay for asus build quality?). was interesting to go through the process, but, sadly, the issue with the digitiser persists. I'm going to do some shopping around and see how much I can get the 32gb model for in store, other wise I may even buy (a grey import) one from kogan.com.
Is the screen actually cracked? I could not make it out from the picture.....If not why could you not just get it sent back as faulty? If there is no physical damage how could they tell? But then again you have opened it now............... Good luck.

No cracks and I thought of this straight after tearing off the security stickers Thing is, two out of the three security stickers I was told to remove in the tear down tutorial were already missing. Also, there were several black (ink/oil?) smudge-y finger prints on the copper shielding when I opened it...hmmm
RIP Nexus 7......
replace!
quicker and cheaper...
repair would cost around 70-80% of a new nexus 7
Bought a cable so we can use a mouse. Problem is the screen is still registering some information from the broken digitizer so as my wife says "It is acting crazy"
From what I hear ASUS is not to supportive of cracked screens so i have resigned myself that it will not get fixed, and fixing it myself is to expensive. ($140 for the replacement part).
So in order to make the best with what we got, is it possible to disable the digitiser interface? I assume I will need root. (not currently rooted, wife's device)
IMO, dont think thats possible?
but if the digitizer is still registering touches, then you gotta find where the pressure points are and try to lift them a bit higher? dont know if that might make sense to you or not lol.
and yeah, ASUS charges an arm and a leg for repairing a cracked screen($165+tax if you live in certain states+shipping charges back to you)

Crack open your device and disconnect the digitiser cable from the motherboard

Get a Bluetooth mouse.. my screen is cracked also.. there is a distributor that sells screens and digitalizers in bulk.. the more you buy the more you save **Hint for business opportunity **

My 2 year old son tripped and dropped my Nexus 7 yesterday now my screen is cracked..
Is it really $140 for the part?
I did a search on eBay and saw some screen replacement part for around $60
I dropped my Nexus 7 today, the screen cracked even though it was in a case. The display is fine, however 1/3 of the touchscreen will not respond.
The bezel is also cracked. Image attached.
So...
Question one: Anyway I can send this in for free with the warranty?
Question two: What can be done to fix it; that won't cost more than the device itself?
Question three: Project ideas to make this thing useful?

Standard warranty won't cover mishandling, which is your case, unless you bought replacement warranty from some retailers;
You can buy the whole assembly for around $100; or you can try salvaging the display by prying it off the touchscreen, buy a touchscreen for about half, then put them together - which is something I'm looking at, though it doesn't look like it can be done in 15;
You can rotate the thing around to control the touch, if you have nothing better to do with your time;
You can use an OTG cable and hook up a mouse to it. This will do almost anything your finger(s) can, albeit cumbersomely;
Nexus has no output to tv or monitor without additional equipment; so best use is to put it on Ebay and maybe recoup some of the cost.
I might get around to the chore soon, and will let you know if you're game.

Well alternatively you could try the fastboot method of replacing/flashing systems (ie: flashing .img files). Also you *might* be able to pick the rom, depending on which portions of the screen is responsive.
Might even be able to do it via adb, if I knew what kind of commands you would give to recovery.
Hi all. ok, so basically i dropped my n4 a few months ago and it cracked the top of the screen a little but it took out 80% of the touchscreen. its only usable now by constantly rotating it in the hope that what i need to touch is in the area which works. I have since bought a new phone (z1) but it seems a waste to have a perfectly ok n4 sitting around doing nothing.
choices are to
a) sell it (not get much for it i'm guessing)
b) fix it (replacement screen and digitizer cost a lot more than its worth doing plus i most likely wouldnt be able to do it myself)
c) repurpose it.
so i guess the real question is, what can i use it for? i cant seem to find any decent remote control apps so that i can use a touch screen of a diff android device to control it so its all a little tricky to do stuff on.
any ideas?
You can buy replacement LCD assembly on eBay for under 130 shipped. If you're in US. The job is pretty straight forward. On YouTube there are a lot of walkthroughs

yeah, i know, i'm in the uk though and they seem to be in excess of £70. given that i mess up putting a screen protector on i dont think i'd be able to put a new screen on. especially given i could probably buy a 2nd hand n4 for about £100 these days it doesnt really seem to a be a lot of point in going to all that effort.

i pulled apart my broken n4 to have a look inside. there's no way i'd bother attempting a repair without the correct tools and lots of skills. it only takes a slight error to mess it up.
I bought an assembly digitizer+screen and it came with all the tools. It took me 13 minutes to take it apart and put it back together. I took it apart later to do the thermal mods too. It's really not that hard. I did it with no static protection, and I was very very careless pulling it apart. I even bent the board with the usb plug on it and it still works.
Seriously just fix it yourself.
well the point of the thread really was for ideas for using it with the dodgy touchscreen. i honestly cant see a point in spending nearly the cost in getting a 2nd hand n4 to repair mine.
Home entertainment console? Combined with slimport or something else this can make your TV a smart tv

Use OTG and connect mouse to the phone through USB. What say?
Repair it.
yeah i'm going to order a usb host adapter. might get a hdmi cable thing too. is there a special type of cable thats required? searching on ebay for them they seem to mention slimport and they are like £20 which is a bit more than i wanted to spend given i'm not sure what i'm using it for yet!
does anyone know if there exists a combined usb host/hdmi/charging cable?
