Other important signs to look for are discolored solder joints around
component leads, mold-like growths and lastly a NiCd that looks like a
wooly-bear caterpillar :(
When the leads get contaminated by NiCd decay, things get ugly as
cleaning the board and redoing the solder connections is a royal pain...
Does the machine coin up? The b/w vector monitor often failed due to
(wait for it...) bad solder joints. Same story. Touch up all the joints
and make sure the HV is getting to the anode. That #$^#@ HV diode and
connector has caused many problems. The connector sometimes disintegrates
into a pile of dust requiring Schieve's RTV hack.
