It's a TV!!! There shouldn't be any "negligent" :-)
Some people are fine with tiptoeing around the problem, I imagine most people just don't do anything and mess up their TV.
I shouldn't have to configure FVWM for 20 days to be able to operate the appliance correctly.
The newer TVs can detect that scenario and turn the TV off automatically, unless you specifically disable that setting.
TVs are a luxury good, and there will always be ways to be negligent with anything. Leaving them out in the rain is negligent. Some cleaners will harm the screen, I'm sure. Using them in a too-hot or too-cold environment will harm them. I don't expect my TV to be battle-hardened, and I'm certainly not going to pay the price for that. Instead, I'll take care of it.
