I have 3 2600 games with no game/tv switches (original). I have hooked each of them up to the RF F connector on the TV set and tuned to channel 3. I get nothing on any of them. Are they broken or am I doing something wrong? Where can I get them serviced? My son-in-law wants to use them again as he has most of the original Atari games for the 2600.
Thanks, Steve.
