Maintenance log

  • 2020/10 - The monitor arcs inside, once every 30 minutes on average (up to 8+ hours without any arcing sounds). The sound is moderate to low, there is video distortion for about ~4 lines (horizontal, <5ms total) when this happens. Opened up the device but no clear culpit can be found. Cleaned the tube (dust) and inspected the anode, but all looked well. Might need Flyback replacement at some point
