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.

He troubleshoots it by swapping the ICs with a working machine, but I only have a working 2600jr with soldered ICs.
Hello Everyone, I just got a hold of a Darth Vader and am trying to get it into working order again and am having video difficulties. It's a Rev 17 board and I'm currently in the process of putting in sockets as I remove the chips. The pictures attached show what my lovely screen looks like as is. Currently I have a known working RIOT chip in it and a new On/Off switch. The RF cable, Missile Command, joystick and power supply all work fantastically with my Woody, so if you have any suggestions that would be great. I was thinking the TIA chip, but before I start desoldering it, I thought I might get some ideas. Cheers
