Nateo Posted January 28, 2019 Share Posted January 28, 2019 I was fixing a friends CoCo2 "yellow bar" problem by replacing the 555 timer. The fix worked initially, but when I put it all back together, the colors were off, appearing too yellow. Wiggling the RF modulator temporarily restored the correct colors. It looks like the colors are too yellow. Would that be a problem with Phase B (pin 10 of the 6847) not making proper contact with the RF modulator?

Nateo Posted January 28, 2019 Author Share Posted January 28, 2019 Nevermind! It's all fixed and working. Looking at the schematic, I was performing a bit of an overcorrection with regards to the yellow color burst. I just wired Phase B to pin B of the modulator, and it was good to go!
