Working on a Hisense LCD40V57CA, complaint no picture, no sound the power board fuse AC250V/AC125V T6.3A blows when I removed the cover I noted the CD296 has bulged and a brownish looking stain on-top, I have not seen any other Caps that are bulged. Would this be enough to not allow picture or sound and the fuse to blow?? I was just going to replace that capacitor then install a new fuse.

Re: Bulged - Capacitor 390uF - 250V
That brownish stuff on the top of the bulged cap is electrolyte. It's probably an input filtering capacitor. Is there another 390uF 250V cap next to the bulged one? 250V is too low for it to be for PFC filtering.
Do any other components look damaged? If the fuse has blown, it's possible some other components nearby failed as well.

However, replacing that capacitor first is definitely a step in the right direction.Last edited by momaka; 04-24-2014, 07:59 PM.

Re: Bulged - Capacitor 390uF - 250V
Kidd, I'm working on a Proscan 42LA45H...It looks as though the boards are the same..
I have the same bulging of the 390uf 250v capacitor...mine didn't split on top and leak, it leaked from the bottom onto the board leaving a brownish stain.
I would like to know where I can find this capacitor...
My local shop has the smaller ones that I ned (2200uf 16v/2200uf 35v) but can't get the 390uf 250v.
I looked online and may have found one on ebay for 10.00..Panasonic
Any help is appreciated.

This is the Panasonic TS-ED 250v 390uF Capacitor, make sure the capacitor you have is 25mm or smaller.

Rated 3000 hours, it'll last a boatload longer though, it should be a direct fit for the one you have there, (25mm x 25mm).Popcorn.
