  1. Video updated with the final results!: Timestamps of updates: 16:18 - Trying ferrite cores for the interference 24:48 - Addressed and resolved screen flickering when pressing fire! Thanks again everyone!
  2. Good news is it doesn't happen at all on the big screen which is the VCS's final home. Updated video incoming! Ferrite cores also make an appearance, solving the interference. I am [emoji817]% done! [emoji3060]
  3. Well it doesn't seem to happen on other games like Donkey Kong so I'm guessing it's to do with that scanline technique ESB uses that was alluded to above, in combination with the composite mod.
  4. I don't think I have that one. towards the end of the video I realized we could hold down fire. it is the very act of the fire button joystick signal traveling to the computer (or from it if it's bringing it to ground) that causes it. Holding down fire stops it. Perhaps a momentary voltage dropout or increase. But I have a new voltage regulator on there. for some reason it doesn't bother me so much. at first I thought it was a clever effect by the game to add more drama! At the very worst it is charming to me, keeping in mind that this is nearly five decades old... ¯\_(ツ)_/¯
  5. Well, I've seen other reports of that exact thing online and they suggest the 4050 chip or the caps by the joystick port. I replaced one cap on each side with the static mod as you saw. Not sure I'm up for replacing all the other ceramic caps just yet lol...
  6. Private draft of the resulting video. Thanks for your help guys!
  7. I just had a breakthrough! I had tried 5 outlets in different rooms and opposite ends of the house. I tried a 6th outlet, with an extension cable, and suddenly the ripple is gone!! The picture is as close to perfect as I could've hoped! So there was something in the electrical circuits bothering the old hardware of the VCS. ¯\_(ツ)_/¯ This is as close to a solution as I could hope so I'm happy to say... drum roll please... problem solved! Thank you all so much for your help.
  8. Hi guys, aside from the 60 Hz interference I've been seeing, I've noticed the whole screen "flashes" or flickers (like a half-second loss of vertical hold) briefly when pressing fire on either joystick. I've tried swapping out the 4050 chip in this heavy sixer, and have also done the field service manual static fix on the joystick port caps, adding a diode across a new cap. No change. Any ideas? Thanks!
  9. Well I've put everything back together and this is the best I can get it. unfortunately the interference looks worse on a better TV. Video: https://photos.app.goo.gl/2J1gqPZgBreE59JG6 But this gives you a very good look at the interference pattern in case that helps some more. Interestingly if I only plugged the left audio in the interference was 10 times worse. Plugging both audio jacks in made things much better, which is what you see. I'm willing to forgive this as it is nearly half a century old, but if you have any other ideas to let me know. Thank you all for your help.
  10. L201 was out a while ago, then back in, and is now back out... No change. I don't know that I still have R210 to reinstall. Do we think that will stop the ripple or not likely? Thanks guys.
  11. I have and it didn't help, but I haven't tried it since the latest improvements. Will try again tomorrow.
  12. Okay. Just that RF ripple moving up the screen to worry about then...
