Re: Nanao 2930 Wavy Screen

mains filter caps normally cause a bad wave in the picture, yours looks to be ground or sync/frequency related

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.
yeah it would be interesting to see if his ms2931 flybacks have the same width issue as the others being sold

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
