Hi All,
I've got a dead LC that I am trying to fix, but I'm not having much luck. When I purchased it, it never worked, but I've started trying to repair it.
Previously it wouldn't even turn on. I replaced the 4 filter caps in the PSUs and the system would now chime but no video. The sound would squeal.
So I assumed that the motherboard caps needed replacing.
I've just finished that and while the system still chimes (and no longer squeals!) there is no video on the screen. My soldering skills aren't the best so it is possible something is still wrong with the caps.
I've got a new PRAM battery installed, no FDD/HDD installed.
If I quickly flick off the power and then back on again sometimes I get a quick white flash on the display, it did that even before I replaced the caps.
So I'm not really sure where to look. Are there specific video caps that I should recheck?
Any other ideas?! Thanks!
I've also got a LCIII that doesn't chime or display video at all, so I'll start recapping that soon, but would love to get the LC working first.
