Troubleshooting: USB-C video problems

PicoPix PicoPix Max (PPX620)

I confirm this solution worked for me, even when performing the flash from a virtual machine (tested on VMWare Fusion with Windows 10 x64 and Windows 7 SP1 x32).

After properly flashing the PPM, I simply connected it to my Macbook with a USB-C to USB-C cable (full data cable, not just charging cable) and it was instantly recognised as an extra monitor.

Thanks @blagerweij ! I wish Philips support had spelled it out for everyone so you wouldn’t have had to, but now we’ve got it.

@Philips_Support_P You should consider including this solution into your original post so it’s more immediately accessible to those facing this issue with their respective device.

Hi @myphilipsid glad to know you could solve the issue. This is not a general problem, it only appears on the very first batches for which the USBC chip was ordered before Apple released the updated MacBook Pros in Nov 2019.

107

@Philips_Support_P I think the problem is not just restricted to the first batch, I checked the videochip firmware version before upgrading, and it was a 2020 version. Also, I had to wait quite some time for the PPM to arrive, so I think the problem is spread wider than just the first few.

Hi @blagerweij yes, you are right, but what I meant is that some later batches of the projector used earlier batch of the PCBA (USB-C chip). The overall number of such units is around 15%.

Did you rename the zip file, and make sure the extracted files are on a local drive, preferably in a top folder (e.g. c:\tmp)

Also, you could try to run with Administrator privileges

Please make sure you use the right usb-c port. Also, make sure you use the correct usb-c cable (one that supports data). The update process is hard, but should work eventually

i’m having the same issue as @Tch3k0v. i tried on a windows 7 VM, windows 10 and windows 11 machine, only on win7 the driver installs using the setup (on others i manually installed it) and on all machines i get this error when the app start.

i tried 5 different usb c - usb c cables + 2 different usb c - usb a. same errors on all.
on all machines i can confirm that i see the USB-SERIAL CH340 (COM3) in device management when the projector is on and any of those cables are connected.

what else can i do? @blagerweij / @Philips_Support_P

EDIT: i already tried the basic “run as admin” and all compatibility options. i also reflashed the projector successfully
EDIT 2: i also tried with the updated 2019 version of the driver from wch.cn, same issue
EDIT 3: i also moved CTools folder out of the program files (to C:\ and Desktop), same issue

I was sent this procedure in November last year by Ivo but never got around to looking at it until recently.

I have tried to follow it, renaming the various folders etc to get it to install

But every time I try and run the upgrade tool it simply goes straight to not responding.
Tried running as administrator, but makes no difference.

Any thoughts / suggestions on what to try next welcome.

I get the same error.
With the path to the executable being C:\CTOOLS\LDRSETUP.EXE
Also tried with compatibility and admin privileges.
I’ll retry on a laptop with unupdated Windows…

Ok, I tried with the PicoPix on and got a different error:

Run-time error '-2147467259 (80004005)':

Hi blagerweij, thanks for your effort in posting this.
Could you share with me a contact for someone from Screeneo that helped you?

Maybe they could help us out regarding the error messages

Is it know which serial numbers are involved? Just got this beamer and it’s unusable with a (windows) laptop or with my phone.
