Yes i do want to replace them just cant seem to find the right ones? maybe im looking at the wrong ones. Could you possibly point towards the correct caps if poss? Those 2 are roughly 25x16ml 63v 470uf and 130 degree.

Re: Phillips 50PF7521d/12 Wont turn on

You probably don't. The original capacitors were of poor design and ran hot, so required a higher operating temperature. Generally, 105°C is fine. Acquiring 130°C capacitors is next to impossible. I'm guessing the caps are Samwha? There is a well known manufacturing defect with a batch of them around 2007~2010.

Your right they are sanwah! And that is probably why i cant find the 130 degree ones if as you say its impossible to get them now lol. So what about heat wise if i was going to swap them for 105'c will they still be able to cope? these sanwahs are bigger then normal caps too.

If the heat inside is hot enough to boil water, I think you have really bad problem in the TV.

Re: Phillips 50PF7521d/12 Wont turn on

TV is all sorted now but i still need to change the 2 samwha caps, ive brought sum 16x20ml stubby caps but will these be ok to fit? or would i need taller caps? whats the difference? Thanks

Stubby caps??

Re: Phillips 50PF7521d/12 Wont turn on

yeah they are like half the size of the gold caps that are in the pic (The samwha ones) but are 105c not the 130c

Re: Phillips 50PF7521d/12 Wont turn on

What is the brand/manufacturer and series (usually a letter code e.g. FC, FM) of the capacitor?

[Johnboy78]

Re: Phillips 50PF7521d/12 Wont turn on

Panasonic FC series 16x20mm EEUFC1J471 - part number. Decided to go with these as ive heard good things about them.
