5" Ultra/Master green screen focus problem

[joe mcnally]

Hello

just wondered if anybody had experienced a similar problem and had a fix ?

My 5" Ultra green CRT works fine most of the time but occassionally loses focus.

A sharp tap on the case normally cures it but I would like a longer term fix.

I have opened up the case and had a careful prod around to see if anything is loose but visually all looks good. Would there be anywhere I could get a circuit diagram for this monitor ?

Many thanks for any helpor advise

I have a similar problem after bouncing a provid monitor off the Stage of the Grand Ole Oprey. It's never been the same since. Do you have any suggestions?

I too have a Master monitor that is has gone soft. It is only sharp when I set the brightness and contrast very low, but it is then too dark to really use in most situations. I use my LCD most of the time when I can, but outdoors I have to go with the greenie. When I do and I am pulling for myself, (on TV and video jobs) I usually end up just cranking it and praying for good focus. I would love to address this issue. Anyone know of a fix?

 

Thanks!
