That looks like a hardware issue. It could be a loose ribbon cable to the display. That would require a teardown to check and fix. If your tablet is still under warranty that would be the place to start.

I was able to open the backside and i reseated the LCD cable that runs to the board connector near the camera, but it still does the same thing.
Could it be possible that the opposite end of the ribbon cable is disconnected? i've never seen an android tablet that has 2 connectors for the display

But, why?!
Is there a simcard slot inside? Im wondering if our Folio is hardware, or software limited to use a simcard.

There is just a place on the PCB for a sim-card slot and also a mini-pcie connector for a mini-pcie datacard, but the parts are not soldered to it.
I don't know if it is possible just to solder the connectors to make it work...

Interessting, do you think it would be possible to mount the LCD upside down? Because i think viewing angles would be better then (like holding the Folio upside down)?
Where's the RAM memory slot?

The RAM is soldered directly on the PCB next to the CPU. You can see it for example on picture BILD2363.JPG. On the other side of the PCB (Picture BILD2387.JPG) is space to solder additional RAM chips.

I don't know if the LCD cables are long enough. But even if so you must then adjust the software. Otherwise the picture will also always be upside down. The better way would be to replace the LCD completely with a different one.
it´s posible to change the camera??
The one think i will change is the LCD and possible add some ram! I don't think it will work though.

I don't think that adding RAM is possible. There might be not all parts soldered to be able to solder additional RAM. Even if so soldering so small pins is really hard.....

This should be possible. It looks like it is a standard USB UVC webcam. But you will also have to adjust the software in order to get the new webcam working.
Do you have some images of the connector of the LCD controller? Also, the Touch panel and LCD should be separated, right? (Can't see that on your pictures)

I have not done a dedicated photo of the connector but you can see it on BILD2355. The brown "box" is the touch screen controller and the cable below is for the LCD. It looks like a LVDS interface.
I think it's a great idea to dismount the device. I'd actually dismount the back cover to see the battery and the sim card slot.
I'll post pictures of it later.

Hi DerArtem
Is you device still working after you opened it and made all these pictures?
I did them same so my Folio 100 to see what's inside, but after assembling it again, the display didsn't work anymore. The device still boots up, I can use it on an external TV (via HDMI) and also the touch screen still works, it just doesn't display anything anymore. Any idea what this could be (and if I could get it repaired somewhere)?
regards,
Mark (NL)
Sure you connect everythink in place? I don't see how it could be broken if you just open the plastic case and remove same screws.

I am afraid that one of the cables that connecto the display with the mainboard was jammed and maybe damaged. It could also be the FFC-cable which has been under some stress (not the cable itself, but the side that entered the connector).
The screen is being connected to the mainboard by 3 cables. A round cable with a board-to-board connector (I'm afraid one of the wires of this one has been damaged), a small FPC connector (flexible PCB) connected with FPC-connector (this one is ok) and a FFC(foil) cable, where I saw that the copper on the edge was damaged. I cut of 1mm of the cable to let the connector grip a little further on the cable, but this didn't help.
So... either the electronics on the display is damaged, but I think it probably is one of the cables connecting the display with the PCB.
Just hope I can get it to work again...
Try to re-fit the cables, if it doesn't work pull the cables one by one and test it against a multimeter. Be carefull not to damage it even further.
Allways connect yourselt to the ground (touch a piece o metal will do the trick ) to avoid static discharges on components.
You can try to send it back to Toshiba, but I am not sure it they will aceppted under guaranty.
If you don't have spares it could be real hard to do troubleshooting. Toshiba (and other manufactures too) will replace the entire parts suspected to be faulty and will charge for it, so if you could do it on your own you will save some bucks.
Good luck!
Hey there
So I changed my Xperia Neo's panel as carefuly as I could
I turned it on but the touch screen doesn't seem to be working although the ligh sensor is functioning properly and all the buttons but when I press the screen it doesn't register the touch could I have broken something or might this be some other reparable problem? :crying:
Thank you for your time.
I found the problem - I've cutted the cable of the digitizer :/
I would like to advice unexpirienced people like me to be very careful when replacing parts of their phones, watch for the tiny cables
Regards!

ya..dear have to be a very careful...with the hardware section....its too delicate ...:laugh::laugh::laugh:
Title says it all really. I dropped it, but it had the keyboard attached and closed, it didn't fall far. However, now it won't turn on at all. If I hold down the power button, it will vibrate for half a second after I hold it down for about 10 seconds, but it doesn't turn on. Nothing appears on the screen.
It's completely stock, not even rooted. Does anyone have ideas?
The LCD screen ribbon cable has mostly come loose. This happen to mine when my son accidentally dropped my prime. Easiest way to confirm this is if you have a micro HDMI cable. Just plug the tablet into a TV and see if you have a picture. If you do then it is the LCD ribbon cable. The battery sits right under the screen ribbon cable and all it takes it a drop and a shift movement of the battery and the cable becomes unplugged. Just take the back cover off the tablet using the updated videos on XDA on how to disassemble the tablet. I used a little pick and two credit cards. The back cover comes off pretty easy and it is real easy to do - REALLY EASY. You will then see the ribbon cable above the battery. Just plug it back in better and secure it with tape. Power on the tablet if you want to check your work. If it works then reverse the steps taken to open up the tablet and you are done. While your in there you can tighten up the "screen" screws if you have screen light bleed too. Hope this helps you.

I think you are right! I plugged in the HDMI cable and got a signal.
Now I'm going to try and take it apart. Wish me luck...You don't happen to have a link to the guide you spoke of do you?
Thanks!

This is the link (How to is disassemble your prime) I used. Worked like a charm to open the tablet up without destroying it up or marring it. Also look at the posts of replacing the screen. You can see the LCD ribbon cable in the pictures. Hope this helps.

So basically you created a thread for no reason. Cable damaged by the touchscreen sensor. Touchscreen does not work. End of story.

the cable is the reason??
the breaded cable are four or five lines.and they are connected to metal surface（i think they are GND)~

ok and the cable that you have circled, the tip of that goes to the touchscreen/digitizer. you said it yourself, "my touch screen is not work......" That's a clear indication that you should look at threads about the digitizer. What are people doing? They are replacing the digitizer and/or the cable. So what's the problem? Go buy a replacement cable. Why did you create a thread when you already know what your problem is, what the effect of the problem is, have a handful of threads discussing your problem already in existence that you refused to/were too lazy to read/go look for, and have various sites such as ebay at your disposal to fix your problem?

You don't know that. It might look like it but I'm sure it actually isn't.
What is the point on having that many pins where all of them connect to GND?
If that piece had no function, they wouldn't even put it in, don't you think?

they are all connected to metal surface of back of the screen~
maybe function just like this :

or something about Static conducting~
i just want to know they are obligatory？
it is feasible for weld another wire to the back of screen ?
if they are obligatory and can not be repaired , i will buy a cable~ i do't want to pay too much money ,the phone worth just ￥300 and i have pay ￥200+ to rpair it .
After replacing my cracked display on my DNA, I'm now getting this error.
I know it's hardware related but I don't know exactly where to look to find either a loose connection or which part to replace.
Has anyone successfully corrected this hardware issue or had this problem after a screen replacement?

One of the motherboard flex cables ( the cable coming from the top assembly where the camera and power button are, attaches to each side of the main board) are not seated properly
Remove the screws and reseat them.

That's what I was thinking. Do you think it is the ribbon on the same side as the front facing camera?
I pressed a little harder and the ribbon clicked into place. all good now.

hi,
can you exactly confirm from where i can press the same? i have the 100% same issue as you faced, i replaced my cracked display all okay except camera its giving error "unable to start the camera".
can you show me some guide or picture from where i can press it after open the handset?
i will really appreciate your cooperation.

I had taken mobo out to replace battery and afterwards camera was giving me same error message. I think it was the long black wire or one of the whiteboards on that side. I didn't have to take the motherboard out again just unscrewed one black tapelike connector, flipped the whiteboards (1 big 1 small), disconnected the long black wire and reseatted them all and it works now! I'm not sure which one did it but they were all on the volume rocker side of the phone.
