I've had issues over the years where this monitor wouldn't display an image consistently, I opened it up last year and found some bulging electrolytic caps on the power supply board, so I replaced the bulging ones and the monitor worked well for about 8 months.
A couple days ago I hooked up my laptop and the monitor failed to display any image at all no matter how many times I tried power cycling the monitor, leaving it off, different devices, video inputs, etc. I didn't even get a "NO SIGNAL" or any of the menus displayed. The blue light buttons on the side light up and my computer detects that it's connected to a monitor but the monitor doesn't display anything, it's just black - no back light, nothing. I have now replaced all of the capacitors on the power supply board even if they weren't bulging, except for the massive 450v cap but I am getting the same issue. Is it worth trying to replace the 450v cap or does it seem like something may be wrong with the video board?
I've attached pictures of the power supply and video board, not images of my boards themselves but they are for the same model monitor, Gateway LP2407.
