XSP-1 New problem

[geten]

I've always had problems with my XSP-1 I got in 2014 (fuses blowing and relay clicking back and forth), but i've minimized the issues by always having the unit on (not in standby mode) as much as possible. Yesterday we had a power outage during the night, and after a few hours the power returned, but i couldn't get the XSP-1 to turn on properly. The lights on the front would flicker blue then some relay clicking sounds and the unit went back to standby (orange). I've opened it up and checked all fuses, which were ok, but also noticed that some capacitors are slightly "swollen" on the PSU PCB (PXSP-1V04) and one seems to have some rust/or leakage? on the MXSP-1V03 PCB (i guess that on is for the front display?). 

So now what to do.. the warranty has expired, and even when it had warranty it was unfortunately not easy to get good help from Emotiva. Btw, i live in Sweden so it complicates things a bit

Your best bet is to contact Emotiva.

Do you have a hair dryer handy? If so, try blowing warm air on it from the top vents for awhile.....sounds stupid but that's what I have to do if mine ever shuts off. I've posted numerous times about this exact issue, I even sent it back for service ( couple hundred dollars ) and they replaced the power supply board......it still isn't totally functioning properly. Good luck to you!

Sell or donate it with full disclosure?

Not sure about the current issue but Sweden is on 230 volts (Australia is 240 volts) and I have had the slow blow fuses trip twice. Which could be due to them being rated tightly for 110 volts (USA) which may be too tight for 220-240 volts. I replaced tham with slightly higher rating slow blow fuses from Mouser, who supply the originals, and I haven't had a problem since. That might enable you to turn it off rather than risk more power outages.

On the current problem, most likely a power surge when the power came back on. Any electronic workshop should be easily be able to replace the capacitors, their values are printed on the sides. Replace with audio quality capacitors.

I have started to buy UPS's for all of my "expensive" electronics equipment, the chances of black and brown outs is growing with the move to renewables.


Cheers

Capacitors are basically a 'commodity' part.    The voltage, capacitance and temp are ALL on the can.   Just duplicate.   But get the right termination type.   ASK YOUR TECH.
To simply get those replaced should be fairly easy.   Buy Only a 'tier 1' brand.    Like Panasonic (computer grade) or Nichicon or maybe Rubycon or ELNA.   

As for the rest?   Now is a little late, but a whole house surge protector MAY have helped.     LEAKY capacitors are terrible and a mess to clean up after.   The Goo inside is nasty.

Other problems are likely, and for THIS?    You may ask for and receive a Schematic from EMO.    Few or NO proprietary parts.   

If it is a GenII?   Maybe a LOT of surfact mount, which is a technology to mount parts directly to the circuit board.    I won't touch it, but will work on more traditional build gear.  

Don't even THINK of plugging it back in until properly serviced.   If the Estimate exceeds what you are willing to pay?    Bad News.   

One last thing?    Can you smell anything?    Burned boards and components emit a VERY distinctive aroma.    That's gonna probably mean trouble.

Please post back when you know more.
