I have the same issue there. I saw another post that said I should replace the TOP202YAI however the thread above seems to say I'd just need to add a single cap. Can someone guide me? Which capacitor do I need and where does it go? The pic in the thread above doesn't work.

I really really need to compile the few fixes we have into actual guides.

That would actually be really helpful!

In your post on the thread I linked you posted an image, do you still have that?

I've seen 3 different fixes for this fault: A full recap, an additional cap added or the TOP102YAI replaced with an TOP224YN.

Just wondering which to try, as doing a full recap seems pointless if there's no reason to.

Full recap on PSU doesn't help with this problem. An additional filtering step is required, hence the additional cap. Or using the TOP224YN.

Here's the image.

What would I be adding, the 2200uF 10V cap?

I have the same issue here, but in this PSU model




Anyone can help me?

I haven't personally repaired JP PSUs, but I was told before once that replacing the TOP chip on them helped. The TOP224YN works for both 220V and 110V input, so you can use those as a replacement.
