I figured out the cap is a 2200uf 25v. So replaced it. Other cap still blew without even turning it on

On mine (board is the same part number) the original C930 cap in the picture (the one circled) is a 33uf 160v cap.

You were correct about this value, but you already knew that.

Can you tell me what the values of all the big caps are? Sorry for to ask, just want to make sure i have them right. So the one I circled on yours is a 33uf 160? Ok well that makes sense now.

I had an issue with my MBP the other night - I was putting together a list for you and did not pay attention to the battery level. I managed to run it out and it just died while I was working on it (I have about 40 other windows and other apps open, but it should handle that, right?) anyway, I'll get it to you later today (Saturday), sorry for the delay.

No worries, psu works now.. just light stays orange.. no crt coming on.. is that psu or analog board now?

Well, I hope that your issue is confined to just caps still. Here is the list, I hope it helps:


There is a service source for the Bondi, but the troubleshooting area doesn't seem good. There is another one for the later ones (2001) as well, which has a better troubleshooting guide and while it doesn't exactly apply, could be used to possibly rule out some things. Just a thought.

Ok; thank-you for the info. All is correct now. I know my flyback was on its way out, as it made the noise of bad flybacks a lot, so probably that. Do you remember where this goes? Little brass plate?

The little brass "claws" go near the AC outlet to help ground everything.

So, this may sound weird, but i didnt need any parts after all. Once i had psu working I decided that to pull the ide to sata ssd and adaptor out that i had put in, boom computer works without issue. I put original hard drive back in and its tickity boo..i did change the analog board because my old one crackeled and flickered so hope the other one is better.
