All Atari home units are single-chip including the original one that Al 
Alcorn himself designed.  I think almost all home pong units of all brands 
are single chip also, except stuff like the original Odyssey.

There just isn't enough PCB real estate to do it all in TTL the way the 
arcade pongs were done.

I would doubt that the chip could go bad that easily, but Atari Pong 
systems routinely fail to give out signals and that's probably due to the 
aging of the other components related to the RF modulator.

Replacing the capacitors might do it.
