You need to replace C102 and C131 on the main board. 47uf capacitors. You can solder some small electrolytic caps on to the existing ones without even removing them.

It's covered in ceramic capacitors, the small orange rectangles, most have markings next to them C and then their number.

Re: samsung pn50a550s1 clicks

so its these rectangles? and im assuming the white line gets the negative side?

They are tantalum capacitors not ceramic. Confirm with a meter but the line usually indicates positive.

so does it matter what side of the cap i solder to them and which 47uf cappacitor? like 47uf 1000 or 2200? thanks
