Re: Creative Gigaworks S750
Well, I went ahead and ordered these, we'll see. Maybe at least I can get it back running again and I will just not turn it off....ever.

Re: Creative Gigaworks S750
Well, i'm not sure, I know that the unit worked well after it was powered on using the hairdryer. I started by assuming that bad caps could be fooled into working if heated up, but I didn't originally consider that other components could be affected the same way.
so how do I know which MOSFET to purchase?...

Re: Creative Gigaworks S750
Well, i just fired this thing up again like i did before, using a hairdryer, it almost powered on, started switching on/off as usual, then suddenly one of the MOSFETs exploded! Now I'm starting to worry that I won't be able to revive this unit.
Now I am looking for a Mosfet, it's labeled IRF740 I*R 343E 6E A3, can't seem to find this exact numbering anywhere.
Also, now that I have it apart I can read the 5th cap info: Capxon info, 450v, 68uF 450V...

Re: Creative Gigaworks S750
Thanks for the replies, I'm digging through data sheets now, I don't know very much about these so I feel like I'm shooting in the dark, can anyone recommend a specific cap?

Re: Creative Gigaworks S750
So, I've been having issues with my Gigaworks s700 which is basically identical to the s750 where it won't power on unless I run a blowdryer on the open boards for 20 minutes, then it clicks for a bit then finally powers up.
Following this and the other thread I replaced the 4 CapXon 470uF-200v HP Vent 105C caps with the recommended MCE ED 105C 470uF 200v caps from digikey, everything is still the same.
I am now thinking that the bad cap could be the 5th cap labeled CapXon KM 105C (C346), but I can't seem find a reference to...
