Odd question. Is there a cheat to destroy television or other gadgets/electronics?

You can shift click and break any appliance or plumbing you like. That said not all are repaired at the same rate so to make it fair someone fixing a shower will take longer than a sink or radio. Buy some boomboxes and shift click each to "break object" OR send them to Evergreen harbor where there are usually tons of broken refrigerators tvs radios and stoves at the smoggy community center if you don't have a "who finishes first" fairness issue
