Capacitor change for LED TV PSU

[unimatrix93]

I have a Hisense LED TV with a faulty PSU.

Found out one of the caps on the PSU is bulged and it makes a chriping noise, while the screen flashing a white line in sync with the noise.

Now I want to replace that cap which is a CD288HC and it's most probably a 25V 330uf. I say most probably because the cap print only says the voltage, not the capacitance. Also, I measured it's size and it corresponds with the datasheet.

Now I need to find a replacement cap, in fact 4 because maybe I should change all of them.

Now I cannot find one with the same values anywhere, which is also in stock so I don't have to wait for weeks.

I found however a 25V/470u one which is also low ESR and imp. rated.

Would it do the job? I know higher voltage rating is okay, but I don't know if higher capacitance is okay too?

The other option is 35V/330uf but they are not low ESR/imp rated.

What should I do guys?

Thank you!

Re: Capacitor change for LED TV PSU

Generally speaking you're safe going up on both voltage and impedance. In your example the 25V/470uf will work.

That's good to know.

Someone recommended me going with low ESR caps for TV PSU-s.
So that's what I ordered. Hope they will do the work.
