Hi Guys,

I have a problem with this chassis, i think that this model have a problem with automatic degauss, and i don't know where is the buttorn for the manual degaussing.

i have this connector on chassis near to degauss connector monitor



any idea about i make a manual degauss


regards

Lucky you, I'm working on mine ATM and I have this chassis in my MVSU4

Just been and took this pic of my degauss button on this cab,

Thank you for reply i press it but do not work

u can send me pictures of degauss connect on chassis ?

I try to connect here but when connect i see only one very slim line on monitor




Regards

Thats the service.
You need to connect it next to the PTC there, aka black box looking thing.

"J1" on the chassis, it's the 2 white cables popping out on the far left.

What exactly does "service" on these chassis?

Just got this chassis in a MVS U4 that I picked up. J1 is just bridged with a jumper wire. Does this mean the chassis can function with auto degauss, or is something else going on?

Presumably, I've got a spare with it jumped also.

I may be able to report back on this as I'm tinkering over the next couple of weeks.

Also there are 2 horizontal width coils, so if you can't adjust it enough on the labelled one with all the controls, there's another, it took me years to realise this so I thought given you have one of these I'd better tell you just incase

Thanks @matt5cott !

Yeah I haven't messed with the coils much, but did see the two. I thought/assumed one was for 15khz and the other for 24khz.
