How do you find out the capacitor is bad. On many brds. Ifixed in the appliance business it was visible and it was just a matter of soldering in the right part.
Same deal here, if you have dealt with blown caps. before you know what they look like. You know how to replace the new part correctly (+ to+ and - to -). There is some common caps. that blow a lot because they are too small for the job longterm. A blown cap will be bulged on top, or maybe a leak around the side of it, or the crosshash on top is split open. Very seldom will you only find just one blown, usually two or three. Here is a website that has a lot of info plus they do sell the parts you need. I will say you can buy cheaper caps. but you have to have the low noise caps. I didn't mean to Hijack this thread, but if anyone needs any more info, just PM me.
And this is their forum if you need to ask specific questions about things.
