We seem to have a different look at the reality of this situation. We need to talk it out. A 9.0 quake is a factor of 100 more than a 7.0 due to the logarithmic scale. If we need to be prepared for a jolt that could be as strong as the equivalent of a 500 ft drop as the Zetas have said. Then, your TV will experience over 1000 to 16,000 times it's own weight to tare it off the wall. This would depend on whether the wall flexed 6 inches or .5". For that matter the apartment would need to take this amount of G-force also. What makes you think the apartment will still be standing? Think of your apartment building traveling along at 122 miles/hr and the foundation suddenly hitting a very thick brick wall. Will your TV still stay in place? Will you apartment still be standing? Not to mention what effect this will have on your body.

Earlier the Zetas said that the 500 foot thing was a totally unprotected dashing of a device. No walls, no restraints. It's on a picnic table in the middle of a field. The jolt comes. It flies. Now, if you limit the fling with a wall, or a padded wall - not 500 feet. If you limit the fling with a padding around it, not 500 foot unprotected dash. The bottom line is not to let our technology get thrown. Cars get moved into other lanes during even a 7.1, and TV sets moved off their perch and onto the floor. Furniture walked across the room during the 7.1 jiggles in 1989 here in San Francisco, so I was told.
We have a couple TV sets, the more expensive one wired to the wall. Unless those screws pull out of the wall, I expect that TV set to be intact with only perhaps a rub mark where the wires cross in front of it. The other TV set, and our PC monitors will be toast, that I know. Count the dishes out too. New crockery. My point, prevent it from being thrown!
