Broken Mantiz Venus
Some help would be highly appreciated!
I was able to get a second hand Mantiz Venus for just 30 bucks. The one selling it to me, already said it was possibly broken, but he couldnt verify since he did not had any thunderbolt devices.
Now I plugged in a Vega 56 and my 2018 Macbook Pro 15 inch, and nothing... unfortunately. Not a single fan spinning or anything... So I took the venus apart, checked the PSU, by shortening the green wire with ground, and then the fan started to spin. I took out the main board, and didnt find any burnt spots or anything. Does anyone maybe have an idea for me to check?
thanks in advance!
Did you ever make any progress with this?
I just got a new Mantiz Venus and the PSU seems to be DOA and no response from Mantiz. My PSU doesn't seem to be powering up at all. Did you get power to the PSU but then nothing to the board?
@don_lee, hey, ive already sold mine because i was not able to find the problem.
What I have done to make sure the PSU did work, was taking a voltage meter, stick it in the 12V rail and ground. Take a paperclip, short circuited the green active wire to ground. The fans started to spin and the voltage meter gave me 12V.
So from here I thought the PSU was working. There could be something else wrong with the PSU, but i think mine was just a broken PCB... I was not able to find any burnt spots or anything, no falling capacitors, and every component looked okay, comparing it to online pictures i was able to find about the PCB.
Even though I have an electrical engineering degree, trying to find a problem without the schematics is a pain in the ass.
