UPDATE: I have tried cleaning the sensors and edges, nothing. I have also tried Ubuntu 24.04 on a USB stick and nothing. BIOS update, also nothing.
I am afraid that it is dead Dave. Time to leave a moose connected out of the dumpster. I like the original Intellimice, they fit me perfectly.
Put your 121gw meter in voltage mode and test to see if there is voltage on the LEDs and go backwards.
if it really is a USB interface plug it into something else and see what it does.
4:51 you can actually faintly see the LED pulsing.
Sure that's not the reflection of the camcorder tally light?
It would be worth booting in to Windows then checking again for any flashing lights in case it is still some driver issue.
@@rjgscotland looks purple which is IR.
That touchscreen emitter/receiver was flashing. Btw, I added a serial port touchscreen to my webserver PC and it included not only drivers but an app to setup and enable calibration of the touchscreen.
You can't expect to work during the POST, or before boot windows and load driver. This module is USB device and need driver to initialize. win10 should recognize if there is properly initialized touch screen device and you can see this when click on properties on my computer icon. Regardless to physical working or not, should be recognized by OS
I used to work for a service centre repairing optical touch screen AIO machines. Always came in for touch screen erratic or not working and 9/10 cases its dirt on the sensors. The purple semi transparent plastic between the case bezel and screen glass are the sensors. Dust on them will screw it up. Just a quick clean with a dry cloth fixed them and a polite note to the customer to keep it clean. Some were horrendously minging and had never been cleaned.
Capacitive touch screen technology replaced this tech pretty quickly.
In rare cases the control board failed but in that case it wasn't seen in the device manager. The boards are almost always connected to the motherboard on an internal USB header and will show in device manager as a USB device.
I was going to suggest the same. This thing is absolutely filthy. I mean yeah it was in a dumpster. But I repaired things from friends and family and I always had to wear gloves and clean it before even attempting a repair. It's so disgusting how people never clean their devices at all.
Nope, that ain't it.
@@EEVblog2 might be a bad controller
Most likely dirty screen sensors, and simplest is to boot off a Linux live USB, and see if that can see the touchy feelly screen, which will tell you it is hardware working and software not being updated for Win10.
Nope, that's not it.
This was before resistive touch screens and smart phones, I still remember how proudly our teacher introduced us to the secrets of this infra light technology. I was bit sceptical how it could be a reliable solution.
I have a few older HP RP7s that my work threw out. The touch screen is a USB device in that case and it always worked normally.
Seeing this reminded me I first used an optical touch screen on a DEC VT100 40 years ago, a database with power system demand at 30 minute intervals going back around five years.
that cable is just a USB cable its crazy that it didn't have a driver that would work with windows 10
Grab a small solar cell, connect it to your oscilloscope and scan the IR emitters to see if they are working.
Some years ago, i had a computer with a touch screen (heavy (in weight) industrial workstation computer). It was given to me only because the backlight didn't work. At home, no problem with the backlights. I did try windows and linux, but no touch screen, until i installed the "original" windows version for that unit. (of course all with the newest drivers).
Simplest explanation is a button on the front that someone turned off the touch screen functionality.
hm... interesting point. I wonder if there are any "monitor only" type settings related to the touch screen.
@@kevincozens6837 I checked in the manual, everything is controlled from within windows, nothing in the monitor itself.
There is a HP touch screen config area in the software.
Boot a live Linux, and see if that finds a touchscreen on boot, it normally will see the touchy feely stuff well. If not then probably a firmware update on the BIOS to latest version might help, and if not that then well plug in a mouse only....
If hardware failure then probably killed by being drenched dozens of times in cleaning solutions, and these destroying the sensors of the optics.
Tried Ubuntiu 24.04 and it didn't work.
@@EEVblog2 Then she's dead Dave.......
Dave ... On the HP's You need to goto Device manager and Goto HID drivers ... in there You will See the Disabled Touch Screen Driver not installed .. Copy the Driver ID and get the Driver from the Screens manufacturwer Forget HP for the Driver as it's built into the Bundled Windows 8 install .. I have had many HP Touchscreens with clean installs and touchscreen driver never installs automatically
It's installed and appears functional.
Linux based systems (including Android) has a many touchscreen drivers already (no need to install anything) and tested with other kernel parts. In Windows, you can make trial and error method all day long - until it will work (for some time...) or not.
Throwing science at a wall, seeing what sticks.
1:12 .. *cackles* .. thats what.. *giggles* .. she said..
I saw the LED flashing. You could hunt down the original Windows 8 Rescue/Installation Discs and re-install the OS. That would install the touch-screen drivers.
yes indeed, it was flashing! it was slow flash, and very faint
Might need to consult an Electronic Engineer 🤷♂️ They can do wonders with all those tiny silicon bits and bobs!
The RAM was in Dual Channel any ways, even with a 4 and an 8, it will use the 4GB and the first 4GB on the 8GB module together as Dual channel, then the remaining 4GB in single channel mode...
while it's not the 'best' configuration, it works - and many manufacturers did it this way in the years around 2012-2016 - when 8GB was starting to show strains, but 16GB was still classed as 'lots' etc :D
Dave Can You do a Follow Up Follow Up on the Working Touchscreen Please Sir ?
Time to measure some voltages maybe?
IR camera to see if there's any life on the touch PCB...
Nice look inside. Still surprised about no SSD, but I see the pads for an mSATA slot. Some higher-end models must have had one.
HP Support has a "Fix a Touchscreen that does not Respond to Touch or Responds Intermittently" YT video, the tests in it should help diagnose the problem.
get a linux live boot and see if it works
Will any Linux distribution work or only a specific one? I'm only familiar with Linux Mint Cinnamon and have never known about it.
@@Lively_1185 Mint uses Kernels from 800 BC, but this thing is also pretty old so it might work.
@@Lively_1185 I would get any one you are comfortable with. There are really only two variants RH and Debian based. The core and drivers though are pretty much the same.
wipe the sensors and the entire inner rubber purple-ish bezel thing with alcohol wipes. probably fix'er right up.
Nope, that ain't it.
Try a Fresh test OS install, See if the touch screen function works withing the installer menus.
Dave, do you still have the good old Garmin eTrex yellow? Any followup on that?
If you maybe decide to buy the new yellow eTrex SE or eTrex Solar, please don't forget to make a teardown video!
I wonder of the LEDs started fading and that's whats causing no touchey
Cameras have IR filters over the lenses, that's why it's so weak.
Windows 10, Windows 11 making landfill like it's 1999.
Yes, Windows 10 would be the final version of Windows and it's not. Have to install GoogleOs or Linux when the support for W10 ends.
@@RoderikvanReekum Switched from Manjaro to Fedora 40 and so far I'm loving it.
Just verify the driver from the device manager
Go to HP support, download the touch drivers for this model - install them. It is normal for touchscreens of this era to be a little bit weird.
I did that, didn't work.
@@EEVblog2 is there anything showing up in device manager without a driver?
@@allan80supra For older touchscreens on Intel laptop platforms: Most likely not - the important question is: Is there anything AFTER installing the driver.
OK - in another comment, Dave already wrote that there is a device with a proper driver.
Probably manual COM port config required.
Is that a burn mark on the top left ribbon❔️
I have PC Touch Screen two it just monitor connects touch from USB, it has it own building USB hub, hub works mouse keyboard, but touch screen, working 😞
Hi Dave, could be an incompatibility with Windows 10, I noticed on the original Video that the bios was dated 2014. On the HP website there is a FAR newer Bios Dated April 29th 2020 with specific fixes for Windows 10. Give that one a go!
Done, but no joy :-(

If the problem is not software related, repair may not be cost-effective. The Pro One 400 G1 manual contains the following information: Touch sensor boards are paired with the touch panel spare part kit. Be sure to do so replace the touch sensor board when replacing a touch display panel. Failure to use the board supplied in the kit could cause the touch module to function incorrectly.
Reseat all the connectors. It could be that touchscreen has never worked on that machine.
You could try using a digital camera to see if the infrared leds are working, same way to check if an infrared remote control works.
