This is a "home theater in a box" unit which (with another Toshiba unit,
the SD-KT50) was the subject of a successful class-action lawsuit. The
unit becomes inoperable with known-good DVDs. Symptoms a at power-on,
the message "Hello... Protection... Goodbye" followed by shutdown.

The only way to remove an inserted CD or DVD (other than disassembly) is
to turn the volume control immediately after power-up and press the
eject button at the same time.

Toshiba's web site states that it is a known problem caused by a
third-party component and is easily fixed by a service technician.
Toshiba is willing to repair the unit but a service facility is some
distance away. I have informed Toshiba that I am a certified computer
repair person, a former amateur radio operator, a retired physics
teacher, and am comfortable with board-level repairs. Toshiba states
they cannot share which component is involved or suggest a procedure to
remedy the problem and it must go to the repair facility.

I have spent a few hours on the 'net looking for an answer to the
problem without success. I'd be grateful to anyone with some information
about the problem, even if it still requires a trip to the repair
service.
