Hello! i need to replace capacitor in my 200CDS inverter and i can't find exact same one with the same capacity, I have 100µF caps, 470µF caps, etc. but the only 10µF i have are 25V ones. Can split two of 10µF 25V caps to create one 50V one? Will capacity add and it will be 20µF? Does it need to be exact same capacity? If not what caps should I use?

IIRC parallel stays at 10µF but withstands up to 50V.
There are a lot of "parallel capacitors" calculators online to help you.
Original is 10µF 50V?

Original is 10µF 35V as i remember

I have the board. If you don't have exact values post a pic and I can check.
Usually replacing with higher V value isn't an issue, µF is important. 50V 10µF, same size should do it.

I found one, it's 10µF 65V so it should work out.
with diffrent cap (also 10µF but 50V) display was very dark on left side and kinda visible on right side, then i noticed SMD resistor missing, soldered it in using hotair and got it from other identical inverter board (had leaked caps too, i guess i am going to use it today as main one because the one i got is little bit hmm... has some issues like broken solder-pads, but the second cap (C1) and this big SMD cap on the bottom are ok so yeah, i am going to have a little bit of work tonight...)

FINALLY I DID IT AFTER WEEK ! ! !
but now backlight flickers a little bit, is it big SMD cap on the bottom (is a little bit darker on sides compared to non-leaked inverter) or the other purple capacitor (i have identical one for replacement)?
Also, has someone working image of harddisk form this laptop with windows 95???

If you can replace old caps, it could help.

i tried replacing smd cap but it didn't help and my inverter now stopped working... no backlight but picture on lcd is present.
ah..
The electrolyte from that leaked black capacitor is probably under some components. Check the SMD capacitors on the back for low resistance - all those capacitors should read fairly high or rising resistance. If it stays at a low value then there's probably cap electrolyte under the SMD parts.
Huh, I was wondering why this seemed familiar, you made a new thread. Here's the picture for what I'm talking about: Re: Toshiba Satellite 200CDS
Also check the fuses - one rectangular fuse on the PCB and one square thermal fuse on top of the transistors held in place with rubbery stuff.
There don't seem to be many functional UA0392P01 inverters left. It's awkward too because I'm fairly sure universal inverter boards require maybe 12-19 volts to operate while this Toshiba one runs on just 5v. So I don't think there's an easily available replacement unless you bodged in one from another model of Toshiba laptop
