Vizio VF550M 55" LCD - PS cap values please anyone?

[nonsub]

Hi folks.

Does anyone know what caps are used in the power supply for these? Per search indication there is no known schematic for these.

Since this is my only TV I am hoping to do my repairs in one shot without missing any of my favorite shows so I would like to have parts on hand rather than pull unit, check then wait for parts order.

These are probably common values even suggestions of what to stock up on would be better than nothing.

Also anyone have insight maybe into something I read on a similar unit that stated "replace all caps except the big one." I take it this would be noted just because it's only really small caps that fail/leak/bulge?

Thanks!!!

I use PANASONIC FM/FC/FR for all my repair, just look at the value and the dimension of the caps, since PS can be more than one revision so you have to get to the board to see exactly what you have.
There is more than one revision of the TV also:

Thanks. Thing is where I am I will have to order/have shipped so there would be a gap between removing and servicing where I would be in TV withdrawal. That's why I'd like get the caps first. Even if I have to buy extras values based on uncertainty that would be fine. So if anyone knows these that would be great.

thx!

I will change out the large cap (the big one), only because of the age of your TV.
