Hi all! I am fixing a colecovision with a corrupted display issue. It will work great forever, until I power it off for a few minutes. On start, it will boot to a corrupted screen and degrade to unstable noise. The power supply i fine, I get good supply at the switch rails so it's not that. Here's the rub. If I push down on L-14 in this state, it will correct. Once it "stabilizes", it will continue to work indefinitely, as long as I dont take any breaks. I played 2600 on the module 1 for 3 hours last night.
Any ideas, and also if it is l14 (believe it's a 2.7uh inductor in the video circuit), where can I find one? google only shows me completely different form factors.
