Atari 2600s not turning on (4 of them)

All of the cables are known good, The units just seem completely dead. 2 of them are heavy sixers, the other 2 are 4 switch units.

Check for loose connections. The power socket could've been damaged over time.

Did one better, stuck my multimeter into the one of them, it is powering on.

1 was a bad power switch, 1 was a bad cpu, 1 is still dead and 1 was a bad connection.
