Sony picture tube preservation

We bought a Sony picture tube HDTV (KV40XBR700S) in December of 2001. It works perfectly -- we've never had a problem and the HD is fabulous. We have never seen a better picture on plasma or LCD or any other format.

The question is this: what can we do to make this TV last longer -- specifically, should we leave it on if it is not going to be used for a while, like half an hour or an hour, or is it better to shut it off and re-start it?

Does the process of turning it on and off cause more wear and tear than leaving it on?

Your advice would be appreciated.

Many unsubstantiated myths will claim that power cycling is destructive. They are correct. And then we apply numbers to their reasoning. Damage will occur in maybe twenty or one hundred years from now. They make claims, and conveniently forget to include numbers.

If they were correct, then you must leave on light bulbs, radios, TVs, your car, etc. These too would be frequently damaged by power cycling.

Logic for leaving things powered is same logic that says power cycling destroys incandescent bulbs. That too is correct if your only knowledge comes from observation - no comprehension of underlying technologies. Those who know better first learn why incandescent bulbs fail AND consult industry data sheets. IOW the observation is wrong because it violates fundamental concepts taught in junior high school science. Observation alone is necessary to promote junk science reasoning. Observation also created other great wisdoms such as spontaneous reproduction.

Hi, Not only a CRT, generally too many turning power on/off on any electronic device is not a good idea. Surge current is hard on the components including the tube. Tony

Hmmm, Are you talking from actual and professional experience? Many good electronic devices have protective circuits built-in to prevent transient spikes risk when power cycling occurs. One example is holding the power supply from waking up until the circuit stabilizes. You can see that in computer power supplies as an example. No doubt transient spikes are harmful at least on theory. Just watch filament of CRT when power is applied. It glows brighter than normal when power is turned on and it settles down to normal brightness after few seconds. What does that brighter than normal mean? Tony, VE6CGX
