Thanks for your cellphone behaviour analysis.
Interesting.
Yes. It is possible the TV power supply is being interferred with.
However, if this is caused by the cell phone in close proximity, I
would certainly expect the behavior to exhibit while the cell phone is
ringing.
It is unlikely that there is a significant change in cell phone RF
output power, regardless of signalling vs. voice channel. It may
change some, but not enough to matter. (i.e., the difference in
antenna response vs. frequency, etc.. Really, not enough to be
concerned with.)
Perhaps the TV is at fault and it has nothing to do with the cell
phone?
Could be a problem in the TV's power supply, or the power quality of
the branch circuit it is using has a problem. (such as: abnormal
line harmonics, bad neutral, bad grounding or bonding, etc..)
You "might" be able to deduce this by trying to replicate the TV
problem by selectivly turning ON and OFF certain high-drain appliances
in the home, especially those with motors. Air Conditioner, Clothes
Dryer (on high heat), Refrigerator, Hot Water Heater, and/or Hot Tubs,
Pool Pumps, well water pumps, etc... if you happen to have those.
Based on your last reply, I am beginning to think the problem is not
with the cell phone proximity. It just sounds like a coincidence.
(??)
To answer one other question, cell phones do not normally "collect and
periodically retransmit" data back to the cell site. Some do, but
they are very specialized devices. Not your run-of-the-mill consumer
handsets.
