Monitor issue

[Yakama]

Firstly does anyone know what model this chassis is?

When it arrived it was dead, a few cracked solder joints sorted and now it starts up but the image is kinda washed out and shadowy, it’s also sometimes distorted somewhat. I will recap it and hopefully that sorts it but if anyone has any other ideas?

It was very clean and doesn’t look like it’s been touched before. I don’t even think it has been taken off the tube before

Looks like a k7000 Wells Gardner

Thanks

It looks like a Wells Gardner k7000 chassis for a 25" tube ( 25K7000 ) 😇

Also should this auto degauss as it doesn’t seem to and I can’t find a button anywhere. There was one in the machine with the coin counter but it doesn’t seem to do anything when pressed

Try turning down the blue cutoff pot or the blue gain pot on the neckboard. They don't have an K7000 chassis don't have a button for degauss (I don't remember ever seeing one anyway). If it's not auto degaussing you need to check that part of the chassis over.

Sorry for the double post, had to refreshed the page first

Thanks ok will have a look at that then

Adjusting those pots doesn’t seem to help

Hmm, it might be a leaky transistor on the neckboard or on the chassis then in the blue circuit. Are either of the pots cracked? Also, just noticed the start of the sentence I typed above about the degauss doesn't quite make sense!
