Touchscreen issues

Hi all, long time away from here. I am having an issue with my touchscreen. It seems the mouse will move to one spot on my sreen and sort of jump around in that one spot and I cannot control it.

I have gone into the BIOS and set display to touchscreen instead of auto, and this does the trick of freeing up the cursor and I can work on the computer. Also, I had to disable one of the HID Compliant mouses, which I am assuming is the digitizer.

Is it my LED panel that is shot, or is it something on the motherboard? I did a complete intall of Win 7 Pro off of my official Panasonic disk, and I have the same issue in a fresh install with nothing but the operating system on it. If it is hardware related, where is the best place to get parts?

Thank you all!!!

Oh, I also ran a complete diagnostic in the BIOS and all came back green. I was like, okay, not hardware, but apparently it must be.

 

disaBLE GPS IN BIOS
TRY AGAIN

if ok then add gps patch--- reboot

 

Hey Shawn,

Disabled GPS, set back display back to auto, started and same thing. Reboot, enabled GPS, went through all of the 4 IRQ's with restarts, same thing. The screen will only work in "mouse" mode, HID Compliant mouse (digitizer I assume) disabled, and BIOS set to touchscreen. Still no touch capability or pen capability. I did complete the Ultra-X PC-Diagnostic Utility and nothing was reported defective there. ????

 

look for dirt between touchscreen panel and metal bezel.

business cards work nice.

 

Okay, tried the business card and it did not get anything and it did not work. This computer is always in a bag unless it's being used. It has not been dropped, kicked, beaten, had anything spilled on it, and it has always worked.

It keeps going to this spot, and when you touch the screen or place the pen on it, the cursor is off by about 2 inches from where I am touching the screen.

Thanks for the suggestions though!!!!

 

Just to make sure the mobo is not confused can you do a battery pull reset...just the battery and power supply. Hold switch on for twenty seconds or so to drain stupid from mobo. Boot to bios and set to defaults.
Re-boot twice.

When that doesn't work in Windows [Superkey] and type cali..... When the box opens look for the reset check box. This resets numbers in the registry. [Save] [Reboot]

If no change then it's a physical problem. GPS issue would jump all over the screen. Could there be a grain of sand in the touchpad bezel?

Does the digitizer work?

Below is a image from my MK6, this is after a fresh install of 32 bit driver bundle. I think device manager should look like this.

Had two errors. This one was 'fixed' by deleting Disp Rotation Tool. I have a yellow thing on ethernet also but wireless works. Tool does not like the versapad.



Windows wants a tablet not a touchscreen. Different size calibration numbers.

 

Here is my Mk5, I just got done putting a 120gb SSD in it. Windows 7 64 bit.

 

I'm getting suspicious regarding the versapad.

Enough so I disabled my touchpad in bios just to see what happens.

The first go around I think I was in the middle of an update....keyboard died and etc.

That didn't seem right so I tried it again. With GPS and touchpad disabled. Touchscreen set on AUTO (tablet). That worked right. Touchscreen and digitizer performed normally.

I rarely suggest something that I have not tried myself.

 

I think CF19 mk6 is when they started Versapad
mk4 and mk5 are Synaptics.

 

Again on my Mk5 No synaptic driver listed in programs.

 

O.K. thanks. Still suspicious.

 

Here is the driver from panasonic

 

Just so all know, I have a Mark 4 with Windows 10 64 Bit, 8 GB of Ram, a 1TB SSD, and all worked fin until about 2 weeks ago. Mouse and everything else working fine but not the touch/pen aspect.

I have been running this system on this computer since 10 came out. I was with MS Technet and demo'd 8, 8.1, 10 preview, 10 everything as I am in the insider releases.

I have all of the 32 bit form win 98 all the way through 10 Creator.

I have tried several different version (32 and 64), XP and Win 7. I even put another disk that had my original 10 in, I get that same thing no matter what.

Again, I am miffed about the system diagnostic passing through all of the tests successfully, and still have this problem.

I have done the MOBO battery out, restart method also.... Still persists.

Very interesting problem I have never encountered before.........

 

I just have a hard time blaming it on the "modern" TS panels. They are very good.

Continuity testing would possibly tell the tale.. Of the four leads, 1 and 3 are a circuit and 2 and 4 are a circuit. I set ohmmeter on "tone" and tape the FPC down so it can't jump around. One circuit is longer then the other so resistance is different between the two circuits.

As always pull the power first. Otherwise, even with the computer off there is 16-19 volts present in the the LCD PCB. (Depending on manufacturer)

And then there is the little wires wrapping around the hinge post. I repaired one once upon a time....like soldering hair.

Did you try disabling the touchpad in bios?

 

Post full model number please.

I would like verification if this issue is the touchscreen, the digitizer or both.

It is even a dual touch unit?

Does the stylus have a button?

If stylus has a button, does the jumping occur with finger and with stylus?

Did you try a live linux usb stick?

 

Okay, in this image I have everything enabled. The cursor on the right in the pen/touch and the cursor on the left is the mouse. I did disable the touchpad and started back up and it is doing the same thing as before.

I have a CF19RHRCX2M, However, I did add a GOBI 2000, so the model I show does not reflect that.

I have no button on pen, so I guess I do not have a digitizer model, just a dual touch (touchscreen/pen) LED model.

I have no idea about the Linux item mentioned.

Thanks again!!!

 

ok.. It is touch only so NO Wacom digitizer.

When we say dual touch we are usually referring to a model that has a touchscreen and a Wacom digitizer.
Yours is a touch only.
Not a big deal, but the way you described yours as dual touch confused things slightly.

Download this iso and create a Live usb stick. It is a complete Linux OS that will run off of a usb stick. You can even pull your hard drive out and this will run. If the touchscreen works with Linux then you have a Windows issue. If not, then you have a hardware issue.

Thanks Shawn. Doing it now and I'll get back to you!!! I really have to think hardware, as I installed the factory disk back on the system and it did the same thing.

 

As you can see in the picture, the stylus is on the left, and the cursor is on the right. As I move the stylus to the right on the screen, the cursor gets closer to the stylus, and when it reaches the upper right corner, bounces around. When touchscreen is set to auto, it does this, when I set it to only tablet, it does this, when it is set to touchscreen and the HID Compliant mouse disabled, it does not do this and the touchpad and wireless mouse work fine, but no touch or stylus. When in touchscreen mode in the BIOS and set HID Compliant mouse to enabled, it goes haywire again.

At least I know it will work the one way, which is how I have set right now. I just cannot figure out if it's the screen, or some other hardware, as I have stated, the diagnostic utility completed with no errors and all boxes checked green for pass.

Guess it will have to go to a repair facility......

Thanks again for all of the help!!!!

 

Just hang on until Sheepman logs in.
He runs this same version of Linux on several Toughbooks and can tell you exactly what it should be.

I think it is the touchpanel itself.
This reminds me, I have a CF 19 mk6 that I need to assemble.

 

Let's not get excited here.
GIJ is getting the same response with Windows and Linux. Verify this please.

This is the sort of thing I see when running touch v.s. tablet. The touch numbers are roughly 1/4 the size of the tablet numbers so machine thinks the screen is 3"x 4".

Let's just see if we can get Linux to recognize the whole screen.

Set bios to TOUCH before we start. <<<

SO: To get MX only running I need a couple answers.
1. Are you using xinput-calibrator? If so:

Code:

sudo rm /etc/X11/xorg.conf.d/99-calibration.conf 

##The why is you may have calibrated with tablet numbers. Then run calibrate again twice! Result should be instant. Reboot after writing new 99-calibration file.
2. What version of MX is this? One of the beta versions didn't have xinput. I heartily recommend MX-17 with update and upgrade.
3. Are you dual booting Windows or running two drives? (recommended)
4. This is going to make your screen touch only. Once we solve the hardware issues we will change back to where both are using tablet numbers.
5.

Code:

dmesg | grep PS/2 -i
dmesg | grep input -i
lsusb
##three lines of code. -i to ignore capitilization
cat /etc/issue

Let's see if this yields any "expected" results. Go slow, get done quick. First Linux for diagnostis and then Windows.

 

Problem is if you send that Mk4 into Panasonic for repair, they will charge more then the unit is worth.Mk4's are fairly cheap.

CF-19 MK4 Core i5 1.20GHz 4GB 320GB GPS Laptop 430 hours for $250 .

$350 for a Mk5 and you will spend all of that on a repair. lets see what we can do here

 

Jeff,
It's the January 2018 release of MX 17
He's running it from a Live usb as far as I know.
The machine is TOUCH ONLY. No digitizer..

 

For now I say it's a bad touch panel: possibly TS PCB. Straightforward repair the third time you do it. IF it's the panel. All bets are off if it's in the wiring around the post.
Too bad I just sold my last CF-19 panel.
Has anybody priced CF-19 touchscreens on bezel? Maybe a beater MK4?

 

Panels are $36 average, https://www.ebay.com/itm/Panasonic-...660978?hash=item282dd589b2:g:I6wAAOSwCU1YwLBL

Mk4 with a bios pass. $89 +14 shipping. Will the panel work from a Mk2 or 3 ? I just looked and 19's are $60+ even for a Mk1

 

mk1 and mk2 panels//tops are ccfl. They wont work.
mk3 and later are led.
mk3 upper should work if I recall correctly.

 

Don't think it's the wiring, I very rarely spun it around and placed it in tablet mode. Usually open and close it and that was it. Will try and find a panel......

Thank for helping diagnose everyone!!! I knew you would all have great answers!

 

If I was doing it, I would buy a really cheap bios locked MK3 or MK4 in great condition, split the screen and just move the touch panel and bezel....with the TS PCB as a reserve if it's the PCB's problem. And assorted parts.
If your Windows bios sees anything it is looking at the ground on the TS PCB. It doesn't see the the layered touch-panel itself. Similar to how a GPS works. Read the CF-29 GPS section several times.

I'm watching an excellent candidate....and not posting it here PM

 

SHEEPMAN! is Awesome!!! Got me on the right track, tracked me down what I would need, and I was able to get it!!! Remember, the members here will help you out.

During all of this, I got my MK2 updated to win 8.1, and its up and running with a GOBI2. I could not survive without my CF-19, in either Centrino or Core I-5.....

So, both are up, albeit Core I-5 without touch, but the parts are the way.... I am hoping I can guess the BIOS PW and get the whole machine up and running...... Good luck to me, but I will have parts to fix my issue.

Again, many thanks to you all that responded and helped me keep my 19 going after many years of service. This is my baby, and I love it!!!! Luckily. I have 2 different service manuals to help me out on the repair!!!

 

Just an update on this thread. Found a bios locked III, brand new! Found an unlocked IV with less than 6000 hours on it. Gutted the III, and placed almost every single component in it from the IV. Pulled my GOBI from MK II, got an extra GPS, another emissive backlit regular KB, transferred my win 8.1 off of a 250 gig HD to my extra 750 gig SSD. Put my win 10 in the newer MK IV and the win 8.1 in my older MK IV. Both are identical except hours and OS's/ Both are working great. I think the whole ordeal cost me less than $300. Great advice from all members who responded!!!!

Many thanks again!
