Vizio 47pfl7432d/37 screen flickering

[whiz62]

Just thought I would post this on what I found. Two caps on inverter board slightly bulged and leaking. They were 680uf 35v. They read only 118uf after removal. All I could find today was 680uf 50v in town. Slightly bigger diameter but still had plenty of room with shield installed.

I posted wrong TV model. It was actually model# VW37L. Got too many TV's. I am Just now looking to try and decipher the brand. Can't make it out. If my ESR meter is correct it read 0.2 on the board. Here is a pic of the caps.

Think budm means what did you put in not take out.

Another bad SAMWA cap, and yes I mean the new caps, the general purpose cap will not have high ripple current rating either to be used in this inverter circuit.

No brand name or symbol on the cap body or package they come in?
