Lots of owners of Plasma TV,s use slides to break in Plasma Tv,s for the first 100 hours of use.You could argue if its necessary,but my question is would it be advisable to use the Shaw Channel FRAME to break in my new Panasonic VT Plasma.
Yes ther is some still photo programs but they do cycle.

There is simply no need for this. It'd be like putting a vehicle on rollers for the first 5000km. It's a waste of energy and needlessly ages your TV. Use your TV responsibly, optimize it, and don't worry about break in.

See the following FAQ - Break in is discussed at the bottom:
