ps3不连电视能开机吗？

No， the PS3 cannot turn on or function without being connected to a TV. This is because the PS3 requires a display device to be able to display its user interface， menus， games， and other content. Without a TV or other display device， the PS3 would have no way to output its video signal or receive visual feedback from the user.

Furthermore， even if the PS3 could somehow be turned on without being connected to a TV， it would not be able to be used for much beyond simple power-on self-tests and hardware checks. The PS3 relies on its software to communicate with the user and perform functions such as playing games， streaming media， and accessing online content. Without a display to show these functions， the PS3 would be functionally useless.

In addition， the PS3 requires a connection to a power source to be able to turn on and run. Therefore， even if the console could somehow turn on without a TV， it would still require power to function， making it impossible to use without being plugged into an electrical outlet.

In conclusion， the PS3 cannot operate without being connected to a TV and a power source. While it may turn on briefly without a TV， it would not be able to perform any meaningful functions without a display to show its menus and content.
