Hi guys,
I have an old Opel (GM) diagnostic computer from the early 90's that needs repair. It was originally working after being taken out of storage for 20 years but one morning the damp must have gotten to it, the anode started letting the smoke out.
The anode lead was sent to be repaired but after installing it again, the CRT wouldn't work. I think it might be the connection to the line output transformer but I can't be sure.
In true automotive fashion, there is no service manual or information on the unit online.
The anode cap also wasn't originally sealed onto the back of the screen.
I'm in the mechanical engineering side of things so I've only learned the basic operation of a CRT. Any help is greatly appriciated.
Back of the CRT:
Transformer and anode lead:
That black stuff on the wire is grease.
Anode lead:
There is continuity between both wires on the anode, can someone tell me if that's right or wrong?
Working Screen:
The unit:
Surface rust on the bottom. No electronics down there, just a storage cabinet.
