Re: Nanao MS8-29FSG issues

thats a NTC 7 ohms, it could be the issue
This acts as a inrush current limiter and affects the entire AC input circuit

Re: Astro city with MS8-29FA - Shorted Degauss

well no because you can see that the chassis has been replaced at some point, the original was a ms9 hence the manual degauss cable- your chassis is configured to auto degauss and is a ms8 so therefore the original connector is not compatible

Re: Lines and clicking sound at low brightness -- Nanao MS8-29FA

these are delicate chassis and tracks break easily, also worth checking the crt socket
check to see where that clicking is coming from- is it from the neck area of the tube or the chassis itself

Re: Nanao MS9-29 (05A00675C1) horizontal collapse

thats a strange fault, if you increase screen volts is the entire screen affected or only that small area?

surely harley is a medium res game, unlikely the chassis you bought is medium res- got a link to it?

it will run but it will most likely run the horizontal transistor too hard, I would not do it if it were me

diiferent chassis behave in different ways, most chassis would just not run and would be fine. These weiya type are very sensitive
