Atari 2600 controllers not working

 2600 Left, right,up, down not working on controller. Fire works but nothing else. Both controller ports have same result. Also I have tried 4 different controllers in each port. I bought this second hand and it came this way. Don’t know where to start troubleshooting. Any info would be appreciated. Thanks

If multiple controllers and both ports give the same results, then it is likely one of the large IC chips on the board. Most likely the TIA labeled as CO10444 or the RIOT which is labeled CO10750. Depending on the 2600 you have, these are either semi easy to replace or not depending on if those chips are in sockets or not.

 

But would suggest starting with the TIA first.
