Sanwa 29e31S-B color issues

[RichSorr]

Hi all,

I have two of these monitors in Sega After Burner Climaxs. The one had a light red tint to it and the other is a little blue. I adjusted both and had them looking decent, still slight red or blue in the white, but after a day or so they slowly fade back to becoming red or blue. The transistors on the neck board test ok, I don't see any suspicious looking caps, but I haven't gone about changing any yet. Does anyone have any suggestions on what could be causing this??

thanks

I have had a lot of crt on these going bad-and i mean a lot,starts with what you describe-in the end one of the guns go
it could be a leaky transistor,for the price its worth swapping out for new ones on each

that is what I was worried about. I am going to replace the transistors and pray. Have you had luck using a rejuvinator on them at all?

you know i have never used a rejuvenator on a tube,always been lucky enough to have spare tubes
