Hi everybody! i have a problem with my LC II (avery time there is a problem...)
Today when i try to start it, the monitor doesn't work, is all black. So i replace the PRAM battery as always, but this time doesn't work. When i continue try to start the Macintosh, now i notice a strange noise from the speaker: can be related with my issue? Can be the PRAM battery that doesn't work (even if "new")?

Usually, this kind of problem is related to bad capacitors on the motherboard.

The first thing you should do is to inspect your motherboard and check if there is any capacitor licking. You could also carefully clean your motherboard. However, I think that if it is a capacitor issue, you may have to replace those bad capacitors.

i noticed some licking near the capacitors, and it is extended to all of them. How can clean this area? Can be the only issue, and if I clean this area the LCII may start?

I don't really know how to clean it but you have to be very careful and clean with something small that doesn't damage any components.

Also, I think to correctly fix your motherboard you may have to replace this bad capacitor. This is the tricky part and if you don't know how to do it you may want to find someone who does in order to do it for you.

I clean the motherboard with a cloth with a little WD40. I'm not able to fix the capacitors. If necessary, i'll tell to someone to help me ( i never replaced a capacitor). thanks another time!!
