  <a href="https://www.youtube.com/watch?v=b9MDo0m3ptA&amp;t=713">11:53</a> is the red markup correct? &nbsp;By this diagram it seems like both sides of the lower replacement capacitor are directly shorted to ground.

  A perfectly acceptable mod for a worn out 1702, otherwise the chances of finding a good replacement tube were slim to none! &nbsp;Now the monitor is usable again and looks cosmetically original.

  You didn&apos;t ruin a thing. You made a worn out display useful and even more capable while leaving the original look and feel intact from the outside. Great mod!

  I admit I was skeptical at first about how well this would work. The results shocked me a bit. I really didn&apos;t expect it to work that well. Nicely done.

  In USSR we also faced problems with croma/luma interference an there was no such thing as s-video at all. So we used to play a trick building high-reciceon rejection filtets that cut only luma frequency not whole upper band. That helped with sharpnes but requred different filters for SECAM and PAL (there were no use for NTSC in USSR)

  This video is golden for me, I&apos;m stuck in a PAL/NTSC world being originally from the UK and brought all my PAL machines across the pond. I&apos;m ordering one of these boards.... and a spare! &nbsp;Thanks Adrian!

  Really enjoyed this one! I tend to err on the side of &quot;restoring to stock&quot; but like how you addressed that later in the video, and there was surprisingly little hacking up the plastics. Awesome stock look in the end! I&apos;m no Commodore expert, but do have 13 (!) of these 1702s awaiting restoration, and can tell you there&apos;s a HUGE variance in the phosphor colour between them all. And.. your new dark phosphor looks great!

  Wow, this is beyond a mod. This is a vintage dream monitor.

  This is a game changer for the North American Commodore community! Having PAL monitor working like that is awesome! 👍

  It is awesome to have a PAL set in North America like so many others mentioned and I agree that the Commodore monitor looks much nicer and fits the retrofit better than the TV did. &nbsp;If you have non-working monitor board that resists revival this absolutely makes sense as a way to restore it to being useful again.

  A seriously comprehensive service menu for set manufacturers not like the limited ones you normally see on commercial TVS. Perfect for this type of DIY project

  This was really satisfying. You ended up with so many benefits that normal monitors don&apos;t usually have. Saved presets, RF, multi system, and it can still function as a TV, if required. <br>Even the compromises aren&apos;t bad. A lower res CRT gives a smoother image - almost like antialiasing for older systems. And you already have other high res monitors when you need them. <br>This monitor is now really special and unique.
