So you need to fix this PSU or buy a PSU that can run the CCFL tubes and another PSU that can supply the CCFL driver with DC voltage as well as make the correct voltage for your LVDS driver board.

PSUs tend to use jelly bean parts so they are easy to fix if you know what you are doing. But don't attempt that unless you are experienced with mains voltage stuff, you can get some serious shocks out of it.

I think that op wants to use logic board to drive a lcd from notebook. Regards repairing power supply, those two caps on the down right seem a bit bulged, so these two would be first ones to check/replace.
Darximor:
I searched for the pinout or schematics and I was not able to find it for this particular model, but I will make further search for a generic inverter pinout compatible with this screen. Another option would be to use the dead motherboard of the notebook to power the screen light.

Yes, the PSU is dead because of the two bulged caps on the down right (I think), maybe it's a bad idea to take risk trying to replace them because of high voltage. Furthermore I wanted to make my own case for this screen and I don't really know how to make it safely for this PSU. But on the other, hand what better than the original PSU ?

And yes, that's exactly what I wanted to do, use logic board to drive a lcd from notebook

You can buy 12V CCFL driver modules from ebay, but you probably need to get roughly the right wattage one.

But if you are reusing laptop screens its best to pick ones with a LED backlight. Easy to drive with just a DC voltage and they are much more efficient (Less heat, less power draw, more brightness)

Replacing this one with led backlit one doesn't help much in this case. In LED ones you have both power and data on one connector, this would require another logic board capable of doing this.

Replacing those two caps is not really hard, and does not involve any high voltage, as they are on low voltage side, and stupidly placed just above two rectifying diodes heatsink. So after some years electrolyte in these caps dried out. Just replace them with ones with the same capacity, and at least the same voltage. And make sure they are low ESR.

I found out some info on these lcd screens, and I think you might need to reconsider the whole thing. Your old lcd has 5V power supply, and 2 channel 8 bit interface, and your laptop screen is 3.3V, 2 channel 6 bit interface. You can find this information here and here. This site has a lot of useful info, good to keep it in bookmarks.
Darximor:
Thank you kjr18 for these heplful link, so il believe it will be really difficult, more than I thinked according to these infos
So I will try to replace these two caps and see what happend
