电视坏了打电话怎么说英语

To report a problem with your TV, you can say:

"Hello, I'm calling to report a problem with my TV. It's not working properly."

Alternatively, you can say:

"Hello, I'm having an issue with my TV. It's not functioning correctly."

If you know what the specific problem is, you can also describe it in more detail:

"Hello, I'm calling to report a problem with my TV. The screen is displaying static, and I can't get any of the channels to come in clearly."

It's always a good idea to have the model number and serial number of your TV handy when calling for technical support, as the representative may ask for this information.
