How could a rig interface turn off your TV? Other than some stray RF getting into the TV or whatever the TV is plugged into for power....

Is there more to this story?

I would second the RF getting into the television.

Do you have a computer near your radio that is connected to a modem, and a cable service provided internet?

Some of these new plasma and wide screen televisions are chintzy when it comes to rf shielding.

After all - to them, there are no hams out there anymore, so they don't worry about TVI, since most people has cable television and no one uses 6 meters except during a contest.

What rock have you been sleeping under? TVI coming from 6 meters hasn't been an issue since TV went digital since they are broadcast in the UHF range.

I don't know how to reply to your answer since you think you know it all.

Not all of television migrated to UHF.

Many signals such as FOX that was delegated to the UHF when first established because the VHF was full, sold their frequency allocation to the larger stations and migrated to the VHF where the cost of running the transmitter was more economical.

In retrospect those signals were probably better off, due to the fact that the government is going to take away another 100 or 200 MHz of the television band for public service and cell phones in the near future.

When that happens, the broadcasters above channel 36 - transmit frequency will be SOL.
In some markets the band plan is already full in the lower frequencies and with a one channel guard there is no room to migrate.

In the near future, you will see more and more stations migrate back to the VHF.

IT DOES NOT MATTER IF IT IS DIGITAL OR ANALOG, IF YOU GET THE TRANSMIT ANTENNA NEAR THE RECEIVE ANTENNA IT WILL CAUSE OVERLOAD WHICH WILL STILL CAUSE TVI.

Most people have migrated to Cable service, which is the reason why you do not hear as many TVI complaints.

I had trouble with my Samsung flat screens.  The touch pad is so sensitive that any RF will mess with most anything the touch pad can do.  Mine would change the source and turn on and off, depending on the band.  I had to open up the tv and disable the touch pad.  Still works with the remote, so I didn't lose anything.  This also applies to some Samsung Blue Ray players.  There are other forums that go into more detail.

The same problem exists with DirecTV HD receivers with touch controls.
A good friend of mine put enough toroids on all the in and out plus power cables of his HD receiver to sink an aircraft carrier to no avail.

He also claims while running high power 75 meters the receiver will order porn channels on it's own.
I highly suspect the last claim may be a smoke and mirrors explanation for his significant other but he sticks by his assertion.

You seemed to have figured out how to reply to my answer!

But at least I don't pull numbers out of thin air that represent the percentage of Technicians out of all the license classes:

Upwards of 65% of all licensee's are only a Technician Class license holder.

I can quote my source. Can you?
