How much "bulge" means a bad cap?
My 50" plasma first lost its component inputs a couple of months ago. I put in a up converting DVD player and more recently went to a Blue Ray on the HDMI inputs and all was good. But now the HDMI inputs have died also.
I pulled the monster off the wall (with some help) and opened it up. I was looking for power supply issues since the component (analog) and HDMI (digital) cannot have much circuitry in common. Also the S-video input with our satellite signal still works fine, so I know it is a issue with the inputs. Thus my assumption of a power supply problem.
Sure enough I found 2 caps with very slightly bulged tops. Both are 3300 μF 100V electrolytic. I have ordered 2 from Allied but am not real confident that this will be a fix.
My question is how much bulge does it take to indicate a bad cap?
