2 TVs in a row shut off randomly

"Is there a lot of vibration transferred to the set? Does the time-honored pound-on-the-side-until-it-works approach correct the issue, at least temporarily?"
no vibration, and I haven't pounded it yet. Will try it next time it shuts off.

It's not external interference if it happens in different abodes.
The clicking may be a overload-type of protector coming out of the "off" state due to excessive current draw or overheating of some component. You hear this with a refrigerator compressor overload switch. It is really a self-resetting circuit breaker. You could use a Kill-a-watt meter to test for current draw compared to the rating on the TV tag. http://www.amazon.com/s/?ie=UTF8&keywords=kill+a+watt&tag=googhydr-20&index=aps&hvadid=2984863615&ref=pd_sl_91tvj6353g_e Bottom line is I'd just replace it and get on with your life. Unless you can spot the problem quickly and repair it yourself, fixing a CRT TV is not cost-effective for the long term.

as it happens, I have a kill-a-watt
but I would assume it would be a spike that causes it to shut off, and I am not sure if the kill-a-watt would catch such a current spike

yeah, I kind of agree 100%, but I still wonder how can I encounter the same defect with 2 different TV sets, from different manufacturers, and in different abodes. seems kind of strange

Replace it -- most likely the high-voltage power supply (around 40,000V) is going over-voltage and crowbarring the safety circuit. This MAY happen with much higher than normal line voltage -- say 130VAC, so you can check that with your Kill-A-Watt. If you have high line voltage, it will affect a plasma set but most likely not affect an LCD or LED.

"EDIT: it was plugged into an UPC"
How were you able to plug it into a Universal Product Code??? :dunno:

My trusty CRT TV, a Toshiba ca. 1996, which I've been meaning to replace with an LCD for the last year, has a picture that turns off suddenly. One solid bang to the side of the set gets it back reliably, at least for a while.
Every time I get close to replacing it it starts to work fine again for a few weeks . . .
