Whoops, my apologies. I completely missed part of this thread. Well I replaced the TIA in my light Sixer with one out of a broken 2600 Jr. I had (used a heat gun to melt the solder and pulled it out) and it still constantly fired. So next I tried soldering Pin 9 and 10 on the 4050 together but it still kept firing. After that, I tried desoldering the pins but they were so stubborn I accidentally ripped the traces around the pins off the board while trying to pry the pins up. However, it STILL constantly fires, so at this point I'm thinking I may as well just replace the entire board, especially with how Frankentstiened this one looks now.
