Help with 1980's Panasonic CT-6000 front projector
I have this Panasonic CT-6000 projector from 1980.
Typical 3-tube projector furniture-type with mirror on the lid and screen.
I've been looking for the service manual in the regular sites where I use to find them with no luck. it seems like it is not a very popular unit.
Just in case, does any of you have this manual available?
The problem with it is that the focus changes with the contrast control por example, and also the focus changes according to how much white the image has. More white means more consumption so either the +B power supply has an issue or the HV power supply has a problem.
I need the schematics for it and the service manual would be great!
Any ideas about what can be causing the problem?
Thabks a lot in advance.
