Mantiz Venus appears to have died out of warranty - what’s my options?

My mantiz Venus appears to have died during operation. It no longer is appearing to windows or Mac, but the PSU “clicks” and turns on when it’s plugged in. The computer refuses to see the thunderbolt connection and I have even tried a new thunderbolt cable!

What are my options when this is out of warranty?

is there a way of isolating down which component it is? The PSU fan does appear to turn on when it gets connected to the laptop, but the laptop won’t see anything. Windows throws up an error saying the thunderbolt device is malfunctioning.

thanks all! It’s a pain because I only bought this 2-3months ago off eBay!

How do other components inside the Mantiz Venus behave when it's powered on and connected to your Mac? You said the PSU clicked when switched on, what about the enclosure fan and the graphics card itself?

The only thing that appears to “turn on” and respond to the cable being plugged in is the PSU fan.

I did some further investigation, however. I ripped apart the Mantiz Venus and took the controller board out. On visual inspection I can see that it appears one of the resistors, labelled CB8 (hard to see) has completely burnt out. The resistor is right near the thunderbolt connector.

In my limited electronics background (very limited, or non-existent), it’s my understanding something “burnt out” is typically symptomatic of a larger problem.

In order to get a replacement controller, Mantiz Venus will charge $120USD + $30USD postage and handling. That’s $210AUD to replace the controller board on something I paid $349AUD for second hand 😐

I’m assuming this isn’t easily replaced? If not and I replace the controller what are the chances of this just happening again? (The GPU operated several months before without failure).

The joys of buying second hand 🙂

Sorry to hear/see this damage on the main board. It looks badly burnt given the marking on the USB-C metal housing nearby. You can try removing it to check the contact points and see whether soldering a replacement is possible.
