Hi @Mika it would seem my board also blew it’s capacitors. Any recommendations on how to get this working again? Would it be possible to send it in or get a refurbished unit?
We don’t offer repair service, and we don’t have any replacement/refurbished units.
I can look up the specifications of the capacitors later on. It may be that they are shorted and are causing the issue.
It seems both the smaller caps and bigger brown unit are done for. If you can please let me know what parts, I can hopefully take it down to an electronics repair shops and see if they can replace them? is that my best option?
I split this to a new topic.
It would be vital to know why &what happened. I haven’t seen such blown caps without reverse polarity being supplied, or large over voltage from the power supply.
And yes, having professional repair done is the best option.
I hadn’t used the rig for a couple of months but it’s the same everything in terms of physical setup, PC, power outlet etc. I turned it on and everything was fine. Went to drive and did about 2 corners and the FFB disappeared and I noticed the unit was not getting power.
I then tried to troubleshoot by turning the unit on off multiple times, unplugging all cables and plugging them back in. I think the multiple on/off made things worse as then I could smell smoke and one of the caps literally went up in a quick flame.
I would seriously suspect the PSU too, maybe thats the origin of the issue.
Yep. Planning to have that tested as well. It’s a meanwell NDR 480 - 48.
When you get a chance, can you please lmk the specs on the bigger brown piece and the smaller caps so I can get the local repair shop to look at it? They said they need the specs.

The big capacitor C13 is a 2200 uF capacitor.

The two capacitors C42 and C43 next to it are 2.2 uF ceramic power supply filtering capacitors with 100V voltage tolerance.

GND is towards the voltage input connector on the board.
The next capacitor C44 is also 2.2 uF capacitor with 100V voltage tolerance (same as above). The installation orientation is opposite than the two next to it.
I would first start debugging this all by removing all these broken components and checking if the 5V regulator works at all, or if supplying 5V to the output of the 5V regulator powers up the system at all. PSU overvoltage or reverse polarity have probably damaged other components as well.

Thank you so much Mika! I’ve sent the details to the repair shop and will certainly keep the thread updated with findings.
@Mika I might as well get a new PSU also. Any recommendations to replace the meanwell unit? Would be great to just order everything off digikey.
I think we would still use the same Mean Well units.
