Ghost Touches

I had exactly this same problem.

I was getting ghost touches sometimes after a few seconds, sometimes after more than a minute.

It was registering spurious touches at the top centre of the screen.

This tablet I bought from someone who replaced the touchscreen with a G01 type with 4822 touch firmware.

I opened it up and noticed they broke a small bit of plastic from one of the connectors for the touchscreen ribbon.

It had about 4 pins exposed so I put a bit of insulation tape over it. I also noticed the black spongy blocks that is normally over the connector was not put back on it.

I applied some pressure on the connector with my fingers and noticed that the ghost touches dissapeared and the touchscreen works perfectly with pressure applied to the connector. I didn't think it was a problem with the bit of plastic missing as the connector has crimping pressure. I tried to pinpoint the pressure applied to figure out where it was iffy and found that I simpy needed to apply pressure SOMEWHERE on EITHER connector! yes even the not broken one. This led me to believe that it is a dry joint causing the ghost touches.

So removed the daughter board and reflowed it in the oven. I used a small bit of solder placed next to it on a bit of al-foil as a heat indicator and let it baked for 1 minute after the tin solder melted into a blob. Melting point is around 220degC so you need to set it at 230-240 at least. Let it cool down slowly in the oven, just leave the door open - DO NOT MOVE IT as the solder is still hot and you can stress damage it. I reflow laptop motherboards and PS3s and I find this method yields high rate of success.

I put the daughter board back in and no more ghost touches!

Remember, switch it off before removing the daughterboard! There is a small power switch on the edge near the power button.

Thanks that did the trick, even though they appeared to be seated perfectly i tried anyway and after reseating and rebooting no more ghost

Thanks for the reply. I ordered a white sticker digitizer and the screen worked great for a few minutes then stopped working all together. I am suspecting I may have friends the pcb board some how since it isn't detected sd cards anymore. I ordered a new pcb board and it detected the card but the digitizer still did not work. I'm hoping that it was just a incompatible pcb board. I am waiting on one I ordered from asus, hopefully that works.

I read as much of this forum as I could, but found myself asking a few questions (my situation was different).

My tf300 LCD was broken, I replaced it. I turned it on and found that the touch screen wouldn't work. I ordered a digitizer, put it back together, and still didn't work. I DID completely disconnect the PCB, and as I read through here, I realized it was a mistake, and that I burned up a "coil".

My digitizer is a G03, and my PCB matches.

from what I understand (correct me if im wrong) If the PCB is disconnected from the tablet and digitizer while the battery is on/connected it burns the coil?

What I need to know is, is my PCB ruined, or is my coil ruined? Do I need to bypass the coil?

Where is the location of the coil?

thanks

I hate to rush anybody, but im going into surgery on June 13th and need my tablet fixed before then so I have something to do in the hospital.

Check it, and if it's burned, just short it.

If not, maybe your old touch was 5158n, then you need to flash firmware. http://xdaforums.com/showpost.php?p=39371862&postcount=104

Chris, i bet your ts pcb is still good. In the future the is a small battery off switch hidden on the edge of the mother board right next to the on off button ribbon. Turn it to the off position. You more than likely need to short the coil as stated in the post above. Check your touch firmware. If it is anything but 3011-4820 you will need to upgrade or down grade. I had lots of trouble "pushing" the 3011-4820 in to the correct folder on the tf300t. I down loaded the 3011-4820 firmware to the microsd and then used Root browser to place it in the touch firmware into data/local/tmp folder. If you are upgrading from 3011-4817 all you need is to reboot the tablet and it will upgrade the firmware. If you need to down grade the you need to use adb commands

# adb shell

# su

# touch_fw_update -u /data/local/tmp/02-3011-4820.ekt

Other option is to place the 3011-4820 firmware in the folder system/etc/firmware/touch and restart and see is it loads and if not then use the adb commands above.

I am sorry but i was so confused on the use of adb and loading sdk tools and platform-tools as well. After weeks of reading this fourm i finally was successful replacing my touch panel glass, ts pcb and flashing a new fw. I had to replace my ts pcb because i broke the ribbon cable connector lock and was only getting half function of the touch panel. Be careful lifting up those white tabs.

Pm me if you need help.

Is there anything I should be aware of while removing the heat shielding stuff off the MB? The last thing I want to do is ruin TWO tablets instead of the one I thought was ruined in the first place.

I really appreciate the responses so soon! This is the exact information I was looking for, and I was hoping it would be somewhat simple.

Broken connector locks

I do laptop repairs and I come across this problem a fair bit. Especially people bringing in their disassembled laptops for me to fix after they had a go at DIY fix. They broke the connector locks and what I do is shim the non-contact side of cable end with layers of sticky tape (trimmed to fit) so that it's a tight fit in the connector.For larger connectors you could glue plastic cutoff from plastic lids etc.

[Transformer TF300T Q&A, Help & Troubleshooting] buff_rob1256:
So my TF300 has recently been registering ghost touches all over the place and now only the bottom third of the screen responds to any touch. I turned on the view touch option and I can see there are ghost touches constantly in the same area.

There is a hairline fracture on the bottom left of the front of the tablet (only in the black area around the screen) and from reading a couple of pages of this thread I guess that's the problem. Am I right in thinking that the whole of the front screen would therefore need replacing? Is that what the digitizer is? If so I'd need to find the specific part number to find a replacement?

Sorry if these questions are a bit dumb, just annoyed that £400 is down the drain at the moment!

EDIT: Had just gone to check on the tablet again after leaving it on for a few hours and it worked fine, until I locked and unlocked the screen again at which point it started doing as I mentioned above. I've already tried a factory reset, but can't try flashing a different ROM as when I get into TWRP the touchscreen doesnt respond :s
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
Hairline cracks will do that to your TS. It doesn't act up right away, but as the tab warms up, it will. Ain't no homeopathic remedy for this. The only solution is a new digitizer. As to what kind, you'd need to read the thread since there's so much information, it's impossible to summarize in a sentence or two. Good luck.

firmware

I would follow Vadimbrk s advice in use the multi meter to see if you shorted the coil. I think you said you installed a new TS PCB? If so maybe it did not come with a pre installed firmware. Is so all the instruction you need is in this thread. You need to read through. Vadimbrk page 9 tells how to upgrade or down grade firmware using ADB. If you are just upgrading firmware you can use my method by rooting with motochopper and using a root browser. Look between pages 25 to 35 or do a search. All you need to learn to replace digitizer, ts pcb, and installing firmware is in this thread. Yes it is lots to read, but helpful.

ADB is not a folder. It is a terminal emulation used with a connection to a windows computer. Yes it is complicated. Search Adb in xda.

The folder you need to place the 3011-4820 firmware in is system/etc/firmware/touch. Read my post on page 30 of this thread.

Another wrinkle: got to test a TS PCB from a friend today. It came off a TF300T but when plugged in, showed 7038 in /touch/ folder and 4822 in “about tablet” tab. The test tab was on CleanRom. I copied the 4820 over to the “touch” folder. No go. I flashed 4820 with Vadim's script. Completed successfully, but still no go. Revert to 10429 official ROM, “about” tablet showed 4820, same result. Had to flash again with V's script, then it worked. “Touch” folder still showed 7038 and last page.ekt. No sign of 4820 in there. Tried G01 and G03, and they both worked.

Tentative determinations:

(1) 7038 isn't just for TF700. If you have it on your 300 tab, you can still flash the correct firmware. I did not need to remove it after getting the PCB to work. If you're stuck with non-working PCBs, it's NOT because of the 7038 being there.

(2) TS PCBs do fail, but not that often. If there's no hardware defect, you just have to try different combinations in flashing. So far, the best platforms are official ROMs for me. I mentioned long ago that my tab started to update its firmware on its own, though it was on custom ROM. That could've been just a fluke. Have had no luck with other tabs on Custom Roms.

(3) Some PCBs will only work with the same MB and digitizer used to install the firmware. Not sure why.

You should start with the hardware first. If you have more than one tab, make sure you test a good TS PCB with a good MB, and vice versa. Any other way will surely confuse.

Please help another luckless with cracked glass

Hello, my son has cracked the glass (5158N device), (he says without doing nothing....)

So, please tell me which is the best to do, given the fact I have now:

1) one TF300T working except the touch (cracked the 5158N FPC-1), not rooted but LCD is working

2) a second TF300T good, perfectly working with ELAN-3011-4822 touch firmware and 5158N FPC-1 digitizer, not rooted

3) a bluetooth mouse never installed

I know that:

a) I have to buy 69.10121.G01 on internet

b) I have to root the brocken tablet

c) I have to mount the 69.10121.G01 and install 02-3011-4820.ekt

I would like to avoid to buy the USB adapter, but I cannot recognise a bluetooth mouse since the touch doesn't work, and before I need the device to be recognised.

So I'm think about:

Solution A)

diassemble the 5158N FPC-1 (plus LCD) from the working device 2) and put in the 1);

let him work and setting;

install the bluetooth mouse;

root the 1) device;

copy the firmware file 02-3011-4820 in 1);

buy a 69.10121.G01;

move the 5158N FPC-1 (plus LCD) from 1) and put back in the 2);

mount the the 69.10121.G01 on the 1) using the original LCD of 1)

Is this correct or do you have any better idea or suggestion... like:

Solution B)

root the good tablet 2)

install the bluetooth mouse on the 2)

copy and install the firmware file 02-3011-4820 on the good tablet 2)

move the 5158N FPC-1 (plus LCD) from the working device 2) and put in the 1);

buy a 69.10121.G01 (without LCD);

mount the the 69.10121.G01 on the 2) using the original LCD of 2)

Solution C)

I think that diassembling the 5158N FPC-1 (plus LCD) from the good tablet is quite easy... but may be better to pay 20 USD and buy the usb adapter...so i would avoid to breack the second tablet too...

Please help..

The reason why 7038 firmware is on a TF300 is unknow...It's not for TF300 that's for sure...

The content of the /touch folder is not that important, I've never seen it get changed after firmware update anyway. Whats important is the firmware version seen in the "about" menu.

Some time when installing a new TS, there is a ghost touch making the TS stuck. You need to reflash(to recalibrate) the firmware again and the TS PCB will ignore that spot. Resitting the TS may also help.

In fact, the majority of "small cracked TS's" can be "repaired" with just reflashing the firmware.

firmware

You should read all the pages of this thread because there are many successful rooting methods as well as flashing the firmware, but it really depends on your situation.

When a read everyones comments and successful rooting and flashing methods, i found it best to use motochopper and the i used a root browser to upgrade the touch firmware from 4817 to 4820 and the restarted and the firmware was upgrades. If you need to down grade you need to follow the adb method.

One comment is the new digitizer needs to be installed first to properly self calibrate and i believe this is also commented on in the thread so you need to read and find it.

Seek the thread and you will find all the answers you are asking for instruction.
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
I tested a TS PCB on a previously working machine with CleanRom installed. All I did was replace the working PCB with the one I wanted to test. However, to answer your question, you can always flash an official rom directly from your PC to your tab using fastboot - which obviates the need for a custom recovery. Or you can install CWM (not touch) instead of TWRP, and use the volume and power button to control.

As to hardware, I don't know of any hard-and-fast rule that would help. You just have to do it by the process of elimination. Once you've done everything correctly software-wise and it's still not working, what else is left?

A reminder: If you have several tabs, remember that making one work doesn't guarantee success where you interchange the components. If you swap a digitizer on one good machine to another tab with a broken digitizer, for instance, there's a chance it'd work for a few minutes then stops. You just have to flash the firmware again with each machine. Copying the firmware to the /touch/ folder often doesn't resuscitate the touchscreen. The V script, on the other hand, never failed me. So you know.

About the ghost touch, are you leaving the digitizer's ribbon unplugged? If you are, you will see phantoms. Plug them in, and the haunting will stop. Otherwise, ghost touches are mostly caused by defective touchscreens. Hope this helps.
