Thanks so much for your post!
As I'd mentioned in a previous post of mine, I also bought one of those modules but did not know how to wire it. Actually, turns out that I had wired it just fine. Your post confirmed it. I also removed Z3 and Z4 (one of which literally fell apart!). My board is heavily burnt and damaged with cracks. By analysing the photos of traces, I managed to wire components together correctly where the traces had burnt or the board had cracked.

​​​​​​Other changes for me were:
I had also cut the mute pin on the TDA previously. I left it like...

Yes please. That is what I purchased ([URL="https://www.badcaps.net/forum/showpost.php?p=915363&postcount=42"]and what the article I mentioned suggests making[/URL]). Would like to know how to wire it all in too. My speakers are collecting dust Re: Mackie CR4 monitors

Re: Troubleshooting 2xFailed Cooler Master v650 PSUs

Thanks so much for your help.
I've attached some photos from around the board including the vertical boards (I didn't see any diodes around there though). I've taken photos of areas where I can spot a diode...

Re: Troubleshooting 2xFailed Cooler Master v650 PSUs




Thank you.
I'm new to electronics repair. Where would I locate the output diodes? There appear to be 4 or 5 diodes on the board.
Would I need to remove the diodes to test them?...

I have a couple of these PSUs that have the exact same issue on both of them. I find it odd that they both exhibit the same Symptoms.

When plugged into the PC, the PSUs are able to power the LEDs inside the motherboard (the standby 5v circuit I suppose?) But as soon as the power button is hit, the PSU powers on for a split second, then there is a (relay?) click and the PSU shuts off. Hitting power does nothing after unless the power is removed and then turned on again.

I have a PSU tester which has the same results. As soon as the tester plugs in, it powers on for...

Re: Mackie CR4 monitors

Hello,

My speakers suffered the same issues as is common with these around the internet.
The [URL="https://www.mikrocontroller.net/articles/Mackie_Creative_Reference_CR3_CR4_Reparatur_Repair"]article linked earlier in this thread[/URL] helped me identify the Zener diode (1N4742A - 12V 1W) that caused the issues.

I replaced it with a beefier one (1N5349 - 12V 5W) and cut the mute pin of the amplifier chip (TDA7265). My speakers were cracking and silent, and after, they worked great.

A few months...
