Atomiswave wei ya intermittent issue

[Zitz]

Hey everyone had my atomiswave with stock tri wei ya chassis and tube for awhile now
And its been great other than this issues that pops up here and there

it seems as the white gun/balance drops out to pink for some weird reason and then itll be ok during this time is if say do a degauss u can see the white going back to normal eventually it goes back , it usually does this issue when the screen attempts to loose contrast or "body" then goes a pinkish colour here is some pics to see what i mean ,

is the tube on its way out?
Could a recap be all it is
Or have you had this issue before?

white gun/balance drops out to pink

It's your green gun (or more likely signal). Look at the fourth pic

Check for loose cabling. Wiggle things around and see if they effect the picture (the RGBS cables going into the chassis, the JAMMA harness, etc). Try a different VGA cable if you're using that input.

pots and drive transistors on neck card burn out on these

Ive tried wiggling everything i get no response, its running a jpac if that makes a diff with wei ya vga cable running from chassis to pc

makes sense about the green as its not there in the pic haha

Ok with the pots some contact cleaner should help?

most of these that come in for repair i have to replace the pots on the neck card, had a few with bad drive transistors and a few with bad bipolar caps- the neck card run quite hot on these which causes these issues
