Atari 5200 4 port issue

[TheQueenV]

Hi I'm Victoria. My wife and I did the power bypass mod on our four-port 5200. It seems to work great until we put a cartridge in. The cartridge will power the unit on and we aren't able to shut off with the console power switch. This leaves us having to unplug the unit. Has anybody come across this? Did we do something wrong? Everything checks out per the instructions. Please help. Thank you

This should have been posted in the 5200 section, but my initial instinct is that that 4013 flip flop chip itself might be at fault here. Luckily that chip is usually in a socket on all models of the 4 port 5200 and is a cheap IC chip to replace out. It is also known to go bad on the 5200s.
