| tim van boekel:
Good morgning everyone, I need some help with a Hantarex Polo 25-inch monitor. I bought a spare monitor for my arcade. The problem when i bought the chassis was horizontal collapse . I replaced R167, which didn't look good and was very out of tollorance. When I turned the monitor on, the image was larger, I heard a whistling sound, and the monitor stopped. When I measured the HOT it was shorted. what did I do? I measured the diodes according to Randy From's diagram they are oke. I replaced C172, C174, and C175, and replaced the HOT transistor. I did the lamp test B+130 volts. Then I turned the chassis back on, and it started ticking again. Then I added another flyback that worked fine, with the same result ticking At this point, I'm not sure where to look. Any tips? regards tim |

Sounds like what happened when mine got 240hz, where the flyback blew....but......perhaps you got the polarity of a cap reversed? |
