m-crew Posted September 9, 2016 Share Posted September 9, 2016 Have an issue with one of my intellivisions 2609 only displaying in black n white(very little colour) Once after a few hours of play. The colour came back. But that only happened once. Any ideas of what is causing that problem or where to look first.. Thanks in advance. Tried to search here and on-line but found very little info on this problem.. Quote Link to comment Share on other sites More sharing options...
+fdr4prez Posted September 10, 2016 Share Posted September 10, 2016 That's all the retro style these days. You need to hook up some rabbit ears, have your child/wife/dog hold them in just the right spot to get a good image 1 Quote Link to comment Share on other sites More sharing options...
m-crew Posted September 10, 2016 Author Share Posted September 10, 2016 (edited) Retro, that's what I have for tv right now. I use rabbit ears(equivalent) and receive the best HD quality for free(not compressed then expanded) and well over 30 channels . Something the cable and satellite companies don't want you to know.. over 7 years of free HD TV...

Well, unless you count my many hotel nights while on business trips 1 Quote Link to comment Share on other sites More sharing options...
+KylJoy Posted September 10, 2016 Share Posted September 10, 2016 Antenna HD. That and Netflix. On the color issue, though not a definitive answer, I would go over the solder joints around the RF modulator. Really, I'd go over them pretty much everywhere while I was in there. You'll have to remove the shield to do it so once it's off might as well go crazy. Kinda' sounds like time = heat = expansion = better connection = loose joint somewhere to me. 1 Quote Link to comment Share on other sites More sharing options...

Yup, I think your right on both thoughts, if I tap the console around the RF modulator. I get the colour to come back.. once I get a chance and time ill tackle that..

mr_me Posted September 10, 2016 Share Posted September 10, 2016 There was a similar discussion here. http://atariage.com/forums/topic/255678-strange-problem-with-an-intellivision-2/ Here is a section from the Service Manual troubleshooting guide https://console5.com/techwiki/index.php?title=Intellivision There's a couple of capacitors directly connected to the colour chip (AY-3-8915) and a bunch of resistors between the colour chip and the rf modulator. In 1981/82 our second television was a 19" black and white, we played the Intellivision on it; no problem. 1 Quote Link to comment Share on other sites More sharing options...

HunterZero Posted September 12, 2016 Share Posted September 12, 2016 (edited) Usually if the RF signal is slightly out of tuning you can lose the colour. If fine tuning the TV doesn't help, the problem is probably in the RF modulator. The RF modulator in the Intellivision has a couple of pots for adjusting it (one is audio, one is video - the one closest to the channel selector is the video adjustment), you could try tweaking the video pot and see if it brings the colour back. C2 is a variable 5-50pF capacitor for the X1 video crystal circuit, you might tweak that too and see if it helps. Checking the capacitors C1 and C33 might be a good idea if you still get no joy. Having access to an oscilloscope the check the frequency being fed to the AY-3-8915 color PROM would be helpful. Otherwise a composite video mod or replacing the RF modulator is the way to go. - J Edited September 12, 2016 by HunterZero 1 Quote Link to comment Share on other sites More sharing options...
clramsey75 Posted December 29, 2016 Share Posted December 29, 2016 I have just moved back to the UK after 9 years in the US and have finally got round to getting my Intellivision out and ready to play. I connected it to the back of the TV via the ANT but nothing happened. I tried it on another TV and after tuning the TV channels I got it to work but the display was black and white. Is there a better way to connect it to my TV? I apologise in advance now but I'm not very tech savvy. Any help would be greatly appreciated as I am due to have an op on January 10th and I NEED my Intellivision to help keep me sane by keeping me away from daytime TV..
