Because the TV is using power to turn on so the lights may flicker because the TV is taking power from the other energy sources around it.
The condition you are referring to is called a power surge. Power surges can damage electronic equipment such as computers and TVs if not protected by surge protectors.
A TV typically uses more power if it's left on for an hour than if it's turned off and then back on. When a TV is on, it is actively using electricity to display images and produce sound. Turning it off reduces power consumption, but the initial surge of power when turning it back on should be considered.

Anti-surge fuses are used to protect electronic devices and equipment from sudden power surges or spikes. They help prevent damage to the device by breaking the circuit when the current exceeds a safe level. These fuses are commonly used in electronics, such as computers, televisions, and other sensitive devices.
I'd be a good idea, but it isn't necessary. On the off chance that there is a power surge and the surge protector on your house doesn't work it will protect it.
Surge protectors are designed to protect electrical devices from power surges or voltage spikes. They help prevent damage to electronics caused by sudden surges in electrical current, which can result from lightning strikes, utility grid switching, or other unforeseen events.
You are probably turning it on with the sleep timer instead of the power button.
Power surges on TVs are typically caused by sudden increases in electrical voltage, which can occur due to lightning strikes, fluctuations in the power grid, or when large appliances turn on or off. These surges can damage sensitive electronic components within the TV. Additionally, faulty wiring or malfunctioning outlets can also contribute to power surges. To protect against potential damage, using surge protectors is recommended.
EDIT: Actually, the gaming console and TV seem to now both work fine when plugged into a third outlet. I had previously tried plugging them both into the next nearest outlet and got the same result (tv turning off and on, console not properly booting) but when I plug them both into an outlet on the other side of the house they seem to work normally. When I plug a *different* TV and *different* gaming console into one of the problem outlets the different TV and console seem to work normally. What could explain this?
Get a good power line spike from a lightning strike somewhere in the area and you'll understand why.
Yes if you buy a new cord for the specific model.
It is a separate component and is used for grounding only. Usually on a TV or electronic power strip for convenience. Most likely the power strip has built-in surge suppression. It is designed to disconnect the load, like your TV, from an over-voltage surge such as could happen during a lightening strike. The in and out cable connectors provide the same type of surge protection from a high voltage that may be induced on the antenna or cable source for the TV during a lightening strike.
