Indeed  they do. They are called "flyback" transformers or "line output"
transformers (LOPTs), they are ferrite-cored as derive their input from the
high-frequency line-scanning circuitry of the TV or monitor.

Output is up to 27kV for a large colour TV -even more for a "projection"
model but such transformers are rarer.

Older transformers produced AC at say, 8kV which was converted to DC at 24kV
by a separate, encapsulated diode-capacitor "tripler";
newer models use diode-split-secondary method of construction and output
high-voltage DC directly without any triplers.

Current-wise, output is in the high microamp/ low mA range so probably
wouldn't be of much use except for powering the smallest of TCs.
