I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.

Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.

I decided to verify that the batteries were...

I have acquired a used Dick Smith Q-1760 power supply - although the OEM is Manson Industrial
It has at least one problem.

The voltage control potentiometer VR2, 50K is faulty - going high resistance / open circuit in the CCW end and leading to the output voltage jumping around.
I have already ordered a replacement potentiometer, so that's not an issue.

Now, I want to replace all three electrolytics on the PCB as they are CapXon and I don't trust them so much, I will replace them with something better while I've got the thing apart anyway.
All are CapXon...

Dear community, I want to increase the lifespan of my backlight led in my TV by decreasing the current.

However I need some help identifying the resistor I need to replace to achieve this.

Thank you!

Hi: Found this forum fumbling over the net looking for replacement capacitors for a high quality 2uv ripple model Kaia, Core Audio Technology LPS. I bought it used on fleabay and figured I would have to recap and sure enough one of the 22,000uf 35V 105c caps is bulging. These supplies were made briefly around 2014 for MAC Mini audio servers, and were quite costly at the time ($1.7k), you know it's audio... I will use it for a video processor power supply to replace a switched version. I figure it's a low cost attempt to see/hear what difference it might make in my system. Plus I get to learn...

Hello everyone.

I'm having issues with my DJ mixer, and after taking it apart and checking everything out, it seems that I need to replace 2 rotary potentiometers for the filter, and that the PSU has some caps burned. Hopefully these 2 fixes will solve my issues.

The potentiometers I will just replace (hopefully the repairman I spoke with will indeed send me the spares, in case he doesn't, I'll update here if we can find a suitable replacement), but for the PSU caps I'd kindly ask you forum members, if anyone could help guide me in the right direction. I'm having difficulty...
