Touch Dual digitizer
Hi Saliml2
Not convinced it is a software issue. My digitizer on T-Mobile Touch Plus did the same thing. It stated behaving erratically and then stopped responding altogether. I replaced the digitizer (via eBay) and it work for a few days and then stopped again.
I have read around the internet and have tried several ROM updates etc (currently running a WM 6.5.5 found in other area of this forum) but this has not solved the problem.
It seem to be an alignment issue - i.e. screen alignment is outside the screen area, but there seems to be no way of getting it back. Could be a fault on the phone mainboard (?) but there doesn't seem to be any info around apart from sending it to HTC for repair (not viable as the phone value negates this)
My phone is still not working, I might try opening it up again and reseating the digitizer cable but have done this twice already.
Have you try change the flex cable?
I had one to, with the same problem, and after changing the flex everything was ok...
Good luck!
Hi Amokh Just to clarify, what is the flex cable? The digitizer has a cable already attached to it that plugs in to a zif connector on the mainboard - I assume that this controls the data flow for the digitizer.
Any help would be appreciated.

Flex cable, i was mean the cable between the mainboard and the lcd block, you can see it in the previous link, picture 20. Have you try it to change?
hello guys how did you manage to put the digitizer cable in place mine doesn t seem to get in place do i need something to hold the connector in place???
My friend has given me his Yarvik tablet so I can repair it. It turned out, he had flashed the wrong firmware image. I can boot the tablet and I can enter the stock recovery mode, but I cannot turn on WiFi and Bluetooth.
It is possible to flash various firmware images to my tablet using the YarvikLiveSuit, I am just looking for the right model number of the tablet.
The specifications of the Yarvik tablet are:
1024x768 (XGA) screen
9.7" display
5V DC adapter
HDMI port
USB slave port
MicroSD port
USB master port
Audio jack
Front and back camera (don't know the resolution)
I also have some pictures: hxxp://imgur.com/a/WV7nA
I have used some filters to differentiate the Yarvik models, but there are 6 possible models that could be the right one:

I am looking for the right firmware to flash. I have already tried these:
TAB465EUK
TAB466EUK
TAB467EUK
TAB468EUK
TAB469EUK
With all of them I can boot up the tablet, but connectivity (WiFi, Bluetooth) cannot be turned on.
Can someone help me out by finding the right Yarvik model?
Thanks in advance.
Shameless bump
Hi all,
Recently, I bought a Sony Xperia Tablet Z of which the previous owner had removed the whole screen. Tablet was working, then he dropped it, causing the screen to be broken (LCD was blacked out, tablet and digitizer/touch still working). He removed the screen assembly as a whole, had the intention to replace it but he just sold the rest of the tablet.
So I obtained an LCD/digitizer assembly form AliExpress, but after installing the screen and switching on the tablet, I got the same problem: Touch is working fine, tablet switches on nicely, I get some kind of 'blind-modus?' that responds to touch with sounds, it tells me I'm swapping through menus, but the LCD itself does not give any signal. Linking it to PC works fine too. Linking it to a TV requires an MHL cable, which I don't have...
My question is:
Does anyone know if this is a well-known problem after dropping an Xperia Tablet? I'm more or less sure it's not the LCD of the replacement screen that causes the problem (given the background), so the problem might be in the LCD flex cable, or worse, the logic board. But how to find the faulty component?
For the flex cable: I've tried to measure (multimeter) the resistance of the wires between each tiny pin of both the connectors of the ribbon, but it's not easy. Some pins on one connector are linked to multiple other pins of the other. Is there an easier way to check this, anyone any experience with this?
If it's the logic board, is there any way to make sure which component is broken, and is this fixable?
If it might help: I have a set of pictures of the logic board / flex / LCD.
Otherwise, I might just try and stop by a tablet/phone fix shop, ask kindly if I could quickly check one of their screens/cables to verify which parts are working/broken.
Thanks in advance!! Kind regards
Edit: I just noticed there is a specific forum for Xperia Z (one), this thread belongs there, sorry! Could this thread be moved there?
Hello! My tablet not boot.
Once in the browser, the screen flashed white and the tablet was able to bootloop. After the logo 'Archos' screen flashes white color and tablet restarts. This occurs in cycles. Term of warranty repair expired. I can go into recovery mode and even download different firmware, but the result is the same - bootloop. I figured that the problem is in the motherboard. i'm found a donor (ARCHOS 80 G9 Turbo) and did transplant motherboard from him. My motherboard revision V2.5 (109376V25), the motherboard donor V2.4 (109376V24). The tablet can boot, but the touch control is not working. The implementation of touch controls on my plate, and the donor is visually different, but I think the functionality has not changed
Please tell me whether there is a difference in the versions of the touch control for different motherboard revision? Or is it my touch control failed ?

Yep, this tablet has different touch screen digitizer chips in different editions of the same model. Try to buy USB OTG cable and turn on Android USB debug in settings using mouse. Then connect your tablet using USB cable (from charger) to your PC. Install android tools and run "adb devices", if your device is there, than run "adb shell". Then you can try to exec "lsmod" there to see which modules are running. You'll find out there your "old" touch screen digitizer driver. Then you can take a look at available touch screen drivers of this model "ls /lib/modules/". You can try to remove old one and load new one (rmmod/insmod) but I haven't tried it yet. I have the same touch screen problem, and haven't tried to root my device yet to check this thing out.
P.S. It looks like you had TR16C0 and Tango F48 chips in your old cover of tablet. And the new one is probably cypress_tma340, but your picture is bad to recognize. Also, touch screen boards are on different plate or cover of tablet with its motherboard. They are connected with ribbon cables to Archos motherboard. Also, have you tried to recalibrate touch screen in Engineer menu (Power button + volume + on start -> Repair -> ...)? If your volume button doesn't work than it means that touch screen cable connection is bad.
Hey, I found the solution to the problem of different touch screen digitizer. Take a look at this file:
adb pull /mnt/rawfs/tags tags.bin
And then give me your tags.bin. Also see this file:
https://github.com/archos-sa/archos...6f53/arch/arm/include/asm/feature_list.h#L224
and this file too:

Also read this topic on FTAGs.

Hi, this problem is solved.
During boot various parameters are initialized, including touchscreen model, namely checks in the service area of the presence of the tag memory "feature_tag_touchscreen" (if (! Tsp || (tsp-> vendor == 0))), if the tag is not found or vendor = 0, then the driver is used for touchscreen "cypress_tma340", otherwise the driver "tr16c0_tsp". My own motherboard was tied to the touchscreen "tr16c0_tsp". Donors motherboard was tied to "cypress_tma340". Because of this, my own touchscreen does not work on the donor's motherboard. In the service area of a memory of donor's mother board had to add the tag "feature_tag_touchscreen" with own touchscreen (tag structure described in "feature_list.h"), to select a correct driver. After reboot touchscreen started working !
I understand that the motherboard has to be tied to their controllers and memory chips, but do not understand why "Archos" did bind to the touch screen, because it is not a component of the motherboard and can be replaced. This greatly complicates the process of replacing. Those who replace the screens and touch panels must know about this.
Thanks to everyone who tried to help and who helped me !
Hello and good day.
I wondering if anyone here knows the Xperia Z2 Tablet well enough to help me proceed to the next step in getting my xperia z2 tablet back in working order.
A little history; I used the tablet on/off when I first bought it, then life took over and I had no time or use for the tablet. Now with a new job starting in 2 weeks time, I could very much do with getting the tablet to work.
I thought the tablet was in some sort of Sleep of Death but it appears that was not the case; I originally tried all the different button combinations, letting it discharge and recharge, used PC Companion to repair, Used Flashtools to repair.
Now, the strange bits; the tablet won't respond to button presses UNLESS I have the micro usb cable plugged in either by charging or connected to a PC/Laptop; whilst connected to a charger it will do the 3 vibrations/led routine. when connected to PC/Laptop it will pretty instantly go in to fastboot mode. and this is the strange part, reboot the device in to system (I also have to quickly remove the USB cable) and can hear it boot up.
all that happens with NOTHING on the screen.
So I had an idea; I attached an MHL cable. Lo and behold I have a picture on my TV, but still nothing on the tablet.
So does any one know where to go from here? could it be a lose connection to the screen??
Seems like a faulty logic/mother board
just need to find a source..
