+joeatari1 Posted December 2, 2019 Share Posted December 2, 2019 Sorry if this was posted previously, but I cannot find a reference for it. I have a Sylvania Intellivision that blinks when being played. I have it attached to a Sanyo CRT TV and when it powers up it starts to blink slowly (picture goes out for a split second). The blinking occurs faster the longer I leave it powered up. This is an NTSC unit. I also tested it against my Mattel system and that one seems to perform flawlessly with the same TV. Could this be power supply? Display chip? Any help is appreciated. Quote Link to comment Share on other sites More sharing options...
mr_me Posted December 2, 2019 Share Posted December 2, 2019 You can test the voltages coming out of the power supply board. https://console5.com/wiki/Intellivision Quote Link to comment Share on other sites More sharing options...
