i had a neotec Nt-s501 with vert collapse. i recapped and its working. i had some issue with vert hold, but adj a pot on the chassis fixed it. still ,im getting color bleed at the bottom of the screen. looked like the neck board pots need adjusting, or does it need degaussing? the neck pots arent marked, and i cant find docs, so dont know what to do from here. i'd also like to check and adjust B+, but no info on this unit that i can find. any help is appreciated.

thanks

most definitely needs deguassing. the pots on all the neotec chassis i have worked on were RGB starting from the corner of the neck pcb.
