Intellivision_II Posted July 27, 2021 Share Posted July 27, 2021 I need help doing it as there is no picture, and only static when the Atari is on. I can tell it’s outputting a video because of the change in static, but it needs to be adjusted and tuned. Quote Link to comment Share on other sites More sharing options...

Are you tuned to the same channel your Atari is outputting to? Quote Link to comment Share on other sites More sharing options...

I am using a plasma tv. My Intellivision II works perfectly on my tv. Edited July 27, 2021 by Intellivision_II Quote Link to comment Share on other sites More sharing options...
+DrVenkman Posted July 27, 2021 Share Posted July 27, 2021 Do you have any access to test equipment? Before you go messing about inside the RF modulator and risk damaging the coil or something, you should verify that you're getting good voltage to the input leg of the voltage regulator, good voltage to the output, and good voltages at Vss for each of the three main IC's in the system. Oh, and that you're using a known-good cartridge as well. Quote Link to comment Share on other sites More sharing options...
