Hey folks,
I picked this neat monitor up from a recycling center years ago, and it worked fine for a long time. I know they are prone to T-con issues with the Altera chip, but I've yet to experience any symptoms of that going. I always perform scaling on the GPU though. It had occasionally thrown a black screen at me, that was usually reset by powering it off, and reseating the DVI-D cable in the sole input. I gave it to my brother who said the problem got worse, and it would be very difficult to get it to display a picture, it took lots of fiddling. As far as I understand him, it always needed a power cycle to work after reseating, which makes me think reseating was probably never necessary, and it was something internal. It worked immediately when I plugged it all in, but eventually gave me a black screen until I couldn't get an image out of it again. No on-screen display of any kind telling me to attach a cable or anything. Just black with backlight shining through.
I took it apart and see at least one bulging cap on the power board, so I'm going to go ahead and replace all the Capxon stuff as a matter of course, though I can't seem to find any spec sheets for these caps so no idea on what ripple current I should be looking for etc.
Obviously, this is where I should start, but is there anything else I should be thinking of?
As far as the caps go, should I just order the best panny / nichicon / decent brand that is the same uf/v and same size?
