I had originally checked the capacitors for leaking or bulging. But I'm not sure I knew what to look for. I know none had burst. Now I know, from weaknees site, what a bulging capacitor looks like. I'm going to reexamine. But I may also plan on replacing the capacitors in the PS anyway.
Where can I find the types of capacitors to pick up in advance?
You want capacitors that are the LowESR type (Equivalent Series Resistance) and rated for operation at up to 105 degress celsius/centigrade.
The microFarad (uF) rating, and working voltage rating should be the same as the capacitor being replaced, although you can go the next notch up voltage wise if necessary, like using a 25V rated one if the original was a 16.
But the uF has to be the same.
The S3 HD used two different model power supplies, and I don't know which one you have, and I didn't make a list of all the caps in mine, I just replace the 2 that needed replacing.
