Shure refuse to supply schematics for their products. For this reason I generally refuse to look at their gear when someone comes into my workshop bearing such units and wanting to know if I can repair them. However, I am seeing a lot of failures in all sorts of equipment these days that use SMD caps. Leaky electrically, leaky physically and shorted are the common states they appear to exhibit. I don't know if it is just one brand as it's difficult to tell who manufactured many of them. Accordingly, I now tend to say "Yes I will have a look (but there is no guarantee I can repair it)" as often it is a case of failed capacitors like this.
@@mojoblues66 There are so many different types of equipment that use these caps. I recently had to repair a Yamaha Clavinova which wouldn't respond to the keys and it was full of leaking SMD caps. Not long after that I repaired an APC UPS which had a mains fail problem - again caused by leaking SMD caps.
I own a clip-on meter for in-circuit cap testing. Do you think it would work to catch these? I know it does a great job of finding open caps, or high ESR caps very quickly.
By upping from 16V caps to 25v ones they will be slightly derated......but it probably won't make that much difference really. I would have done the same.
Wonderfully methodical.
Thanks for sharing. Another great video.
It's only a little over 7 minutes, but I'll take it! ....:) Really enjoy your process and appreciate the content. Thanks!
Great work and a bit of an unusual fault too...cheers.

That type of cap is also causing a lot of trouble in the retro computer scene.

Great!! Thank you.
Nice fix.
Good job.
Good morning Sir! I have a set of Shure ULXS4 -J1 that is bad, do you accept repair?
I own a clip-on meter for in-circuit cap testing. Do you think it would work to catch these? I know it does a great job of finding open caps, or high ESR caps very quickly.
What sort of a meter? With 3 leads auto-detecting stuff? Shouldn't it say something like "resistor 0.2 ohm" if there is a short?

I was going to say the 12v reg had a short to ground as I could see it pulsing on the Flir, so it was entering protection mode from the overload.
Hello how can I contact you?
I have some ULXP that need repair.
You are awesome.
Nice!
Two at once is unusual. Nice easy fix, this time.
SMD Capacitors are very bad. I replaced all for my Roland VS2480, Audio technica AEW5000.
Electros usually turn into resistors, so that's weird.
I've had my share of shorted electrolytics over the past 20 years and I am seeing it more often as time goes by.
