I have a hantarex polo 25 that is ticking. searching for similar issues online, it seems like everyone with ticking has no neck glow, but i get neck glow each time it ticks. does anyone know what could cause this condition?
the monitor was working previously, with picture issues. i replaced all electrolytic capacitors, flyback, and HOT, and it looked great and ran for some time. since the ticking started, i've since replaced the voltage regulator, and following the polo flowchart, replaced the HV caps c170, c172, c174, c175, and diodes d129, d135, with no luck. i found a bad trace on one of the flyback pins as well, and have soldered a jumper wire. everything from the flowchart checks out as far as i can tell, though i don't know how to test the flyback.. reading the b+ i get ~30V and each time it ticks/neck glows it jumps up ~70V.
thanks in advance for any info or guidance, i have been working on this thing for weeks and its driving me mad
