Re: Sanwa 29e31s-b No Picture-total black

pot could be broken, you can read on ohms with a meter- centre leg to one probe and a probe to either of the other pins
it could be tube but colours look too vibrant to be a tube issue

Are these the same flybacks used on a MS2931/MS2933?
no but the same seller does stock them
Excellent! Thanks Grant.

Re: Sanwa 29e31s-b No Picture-total black

its probably ok, only a super high quality meter would read that resistor correctly

Re: Broken potentiometer

202 would be 2k ohm
you can also read using a multimeter, adjust pot fully one way and then read centre leg to one of the outer legs, one leg will read min resistance and the other the maximum resistance and this leg is the actual pot value- read out of circuit

Re: Rainbow Swirl on Screen When Off

a voltage on the chassis is not shutting down correctly, it could be a fault in the video b+ but nothing major

Re: Astro City Blurry Screen issue

you get a small length of wire and short one end to pin 1 and the other end to pin 14

you should check the neck card is fully home and the crt earth wire is connected tot he neck card
