Lol and thank you. Nelson keeps me grounded. Just when I think I know what I'm doing I look up to find him pointing at me and saying "Ha-ha!". Thanks for watching :)
So I went ahead and replaced all capacitors on board except the big one which seems to be in a good condition. I found some corroded resistors which I checked and cleaned and replaced a broken one. I believe the board I worked on is the next revision. There is no C922 capacitor and found C937 is 33uf 50v rated. Since I have already ordered 35v ones I just put that one in. Did not explode 😉 So far so good . Green iMac G3 450 is back on duty !
Hello, many thanks for the very informative video. I have slot load G3 450Mhz model and recently it started to load image on the screen very slowly. When warmed up it continued to work normal. The last few days it get worsened. It attempts boot in a continuous loop and sometimes manages to load OS with screen briefly on and then off. I'm checking PAV and see on C947 16v47uf cap base brownish oily stain. Is it possible that a tiny cap can make all this problems? or maybe the Flyback transformer could be the main cause? I'm considering if I'll go to all of PAV overhaul time/cost process. Cheers😀
You're welcome and thank you for watching. Its difficult to be certain without a schematic, but your problem sounds very like a capacitor issue and I'd be surprised if it wasn't more than one which needs to be replaced. The majority of those on my PAV board were neither bulging nor leaking but almost all registered at best a marginal ESR. Good luck!
I also got the same slot loading imac in orange but the ssd doesn’t recognise when i put in the 10.4 install disk i tried formatting it and partioning it to 120gb but it doesn’t help does someone got an idea maybe it’s the old idea cable
Your Nelson figure has been cracking up. lol Great Video btw!! Love these fruity AIOs!

That is fantastic news, well done! Such a joy to be rewarded for all your hard work with a machine that is back to good health :)

mine literally exploded because when i got it it smelled burny
