  1. Looking for a working TIA chip, preferably solder-free. Trying to fix up 2600 Darth Vader (see http://atariage.com/forums/topic/268563-2600-graphical-issues-tiariot-issue/?p=3821875)
  2. These are, in fact, socketed ICs so they are easy to remove. I also removed, cleaned and re-seated the RIOT and TIA, but no change. I broke out some earlier Atari games as recommended In combat all of the playfields seemed correct but the tank’s positions randomly changed and the blue tank spun around at the left side of the field. Space Invaders looks almost perfect, though vertical lines appeared sometimes. Bullets also seemed misplaced. Super Breakout has some misplacement as well. If this is still looking to be a bad TIA then I’m going to order a replacement. I’ll post in “Wanted” like @RamrodHare mentioned, but I’ll get one from Best Electronics if I don’t get a hit after awhile.
  3. I recently purchased a 2600 Darth Vader at a yard sale. The unit was labeled ‘2600 Original Needs Work’. It was $15 so I decided to pick it up anyway. I fixed the first issue which was the power jack not making connection with the power cord end. Now that the unit powers on, it displays incorrect graphics. From looking around on threads, it seems that this is an issue with one of the ICs. I am unable to get a clear answer if this is a bad TIA chip or RIOT chip. I would rather not buy both unless necessary. Does this seem to jump out as a specific issue to anyone? Any help would be appreciated. Symptoms: Misplaced/distorted graphics No (or very little?) sound Related(?)

He troubleshoots it by swapping the ICs with a working machine, but I only have a working 2600jr with soldered ICs.
