Can I replace 30v 180uf cap with 35v 180uf? MPC clientpro 414 17" lcd inverter board?

[ALUMINUMWELDER]

this is my first post so I apologize if I make any mistakes.
three images below show inverter board, top, middle and bottom.
I have 40 of these all in one 17" LCD computers and they all show the start up screen for a split second and then show white text for a split second before going completely black. Although the PC's are very old about 10 years I'd rather fix them then throw them in the landfill.

the middle photo shows two green and gold capacitors, which are labeled:
NK CON 30v 180uf 105 c f2053 EVL

I want to replace them since they are reading 40uf and 90uf with multimeter.
I have already swapped out a good inverter board with a bad one (on two pc's) and got a PC working again so I know it is something bad on the board.

I cannot find any 30v capacitors on mouser.
can I use this 35V one instead? I know I can use a higher capacitance rating, but i'm not sure about voltage?

Yes you can, but it has to be LOW ESR/IMPEDANCE type. I use Panasonic FM/FC/FR series for all my repairs.
You should recap the whole board except the main filter cap.

thanks for the quick reply

the product spread sheet says 56 mOhms is that low enough?

I only see two capacitors on the board, though I admit I am an electronics novice and do not know what everything is just by looking at it.

"the product spread sheet says 56 mOhms is that low enough?
What product spec sheet, the spec sheet of the original?
If you get the FM series it will be good for sure, FR will be even better doe to longer Hrs.

MOUSER says it is FR series FR1V181
I am talking about the product spread sheet on mouser's web site
I posted the link above in first post.

I am so happy I was able to figure this out by reading this forum and getting help from people like you, thanks!

Yes it will be ok to use that capacitor. Going up on the voltage rating by 5v isn't going to make any difference. What Bud said, if you're going to buy and replace one cap you should do all of them.
