So I've had this monitor for probably a decade now, and it's finally starting to fail. Began with a little sporadic flickering, then eventually started going black (power LED stays blue, can still see image on screen with flashlight). A power on/off fixes it for a bit, but then it happens again. Once it got to the point I was dealing with this every few minutes, I opened it up and just replaced all the caps (minus the big one) on the power board with new Panasonic ones. All the old caps tested fine on an ESR meter, and this worked for 5 days. But the screen just went black again today, so there has to be something else. Since the monitor is still functional for now, I figured I'd ask on here to see if anyone has any idea what to try next before ripping into it again. This slow failure mode is kind of annoying, as I can't really test new components well without letting it run for days.
I'm thinking I'll try swapping the caps on the logic board, but would they be able to cause this kind of failure at all? Or would they be showing issues other than just backlight failure? Should I swap the big one on the power board?
Also thinking it may be the CCFL backlight itself, can I just pull CCFLs from a similar sized monitor or are they model specific? Not really sure if buying new ones is worth it for such an old monitor that I'm using for a 3rd display at this point.
Anything else to consider? I attached the bad photos I took before, but they were mostly a reference for myself to be sure all the caps were replaced correctly. I've done a few cap swaps in monitors before, and they had fixed the problems so I was hoping it would be the same here.
