RME Fireface 800 flashing lights issue

Hi all,

This post is about my Fireface 800.

Lately my RME has been acting crazy : all of the lights are flashing (in a middle of a session!) and I hear clics and pops...

I've contacted RME for a repair but unfortunately is above my budget for now.

I think I need to re-cap my RME. (a least 6 capacitors need to be swapped, at the back of the unit). The capacitors of the power supply card seemed to be fine. (?)

I've attached some pictures below.

Best regards,

Yeah, IMG_0926.JPG showing the row of caps does appear as if they are bulging!
Not sure what part of the circuit that is, but the JRC4580 chip there is a Dual OpAmp. So those could be your input stage or the output stage. You should trace those circuits back and figure that out. Did you have something connected improperly?
There must have been something that failed in that section to cause the caps to fail....
Replacing the caps will certainly be needed but what other components could have failed along with those....that is the question....

RME Fireface 800 flashing lights issue

Hi Djmukilteo,

Thanks for your message. I'll check these 6 condenser for a replacement.
I've bought the unit second hand a few years back... I guess the first user used it intensely - could be one of he reason those caps are dying...

I hope to solve this issue asap.

Anyone experienced the same kind of problem (flashing lights, bugs and a lost of connection via my computer) and solved it?

thanks
Nate

The only solution you have is to try and repair it. It's a matter of troubleshooting the cause of those blown capacitors. If you're not technically inclined in electronics, then I would take it to someone who is.

Hi,

I've bought a set of capacitors to replace those shown @ pic IMG_0926.
I'll give the RME and the capacitors to a technician for soldering & a full check up.

I'll keep you posted!

Thanks for your help

Hi,

After replacing the defective capacitors, it's working perfectly.
And there is much less heat from the unit.
I just love those RME converters!!

Thanks for your help everybody,

Peace!!

Glad you were able to fix it. Any idea what actually caused the caps to fail?
Did you ever determine which section of the unit those blown caps were in?
Any photos of the overall repair?

Thanks Djmukilteo!

The almost blown caps were in the output section (1, 2 & 3) 2 capacitor for one output.

I've bought it secondhand so I think the first user misused it, something like plug an output to an output you know.. I don't really know..

I've already closed the unit, and I didn't took any pictures..

I'm planning to buy a second unit to have 16 outs..

Take care & peace!

Output section would make sense like you said previous owner did something wrong....but glad you got it sorted! Enjoy!

That's fascinating. Normally the mainboard caps don't have a lot of heat and won't dry out for decades, so I am wondering what caused yours to do that... Perhaps there was a lot of heat in that area of the motherboard for some reason, like the previous owner placing it in a rack next to a unit that was super hot at that location and transferred its heat into the Fireface... still very weird.

In almost 100% of cases, blinking lights are caused by a dead power supply. I've written a tutorial with links here:
