Black screen after cleaning PSU?

Question

Power Supply

I disassembled the computer and completely cleaned it, I got the idea to clean the power supply, took it apart, cleaned it, orange dust was noticeable on 1 barrel and it was a little swollen, in the end I put it all together, everything works but the picture does not display, I checked the "video card, pull out all the pins on motherboard, except for the case panel, changed the RAM, the processor "cleaned all the inputs and outputs and wiped the RAM and video card with an eraser, in general, I tried everything but the pictures are still missing, the power supply is Chinese fsp at 230 watts, can the power supply somehow affect on an output of a picture on the monitor?
