PG32UCDM flashing white red blue and green - no reset possible

[Takumosan]

Hello forum/support,

today I started up my approx. 3 month old PG32UCDM to find it having the same problem as @ibby @Aureliannn_ROG  recently postet, but there is no solution mentioned in that thread.

The only thing the monitor does: switching through red/blue/green etc. fullscreen test screens

I cannot access the OSD; I have the MCM103 firmware installed since shortly after it got released; the firmware-revert function (pressing the 2 buttons while plugging in the power) shows no reaction

I am using DP, but I now also tested HDMI, different cables and used another PC - makes no difference

So currently the PG32UCDM is completely bricked... pls help!

Hi @Takumosan ,

according to your issue, please confirm if rolling back the firmware to version 101 using the following method can resolve the issue: 

Press and hold the physical left button and power button while the device is powered off until the screen lights up.

Thank you.

Hello @Aureliannn_ROG ,

thanks for the feedback. But as written above "firmware-revert function (pressing the 2 buttons while plugging in the power) shows no reaction". I tried this procedure several times as described, but the monitor just switches back on and immediately shows again its' "test mode" colors unfortunately.

Hi @Takumosan ,

thank you for providing the update. 

If you have already tried rolling back to a previous version but the issue still persists, we recommend taking your monitor to a nearby official repair center, where an engineer can diagnose the actual problem with the device. 

You can refer to the link below for information on repair locations.

Thank you.

Just wanted to report back here if someone else might run into this issue on his monitor.

I filed a claim towards ASUS support last monday with my problem description and a few photos. Later that day received a confirmation that my defective monitor will be picked up and replaced by a new one - no further questions asked. Thanks for the excellent service!

Although the PG32UCDM is still not available again in Germany since I bought it in March, they obviously have some stock available and I received the new monitor today (Monday) (with a little delay thanks to UPS...).

After all, I would of course still be interested in the rootcause - hardware? firmware? Just in case, installed MCM105 today if it was an 103 firmware problem.
