Turning on a cold Plasma TV

post #1 of 22
Thread Starter 
I receive shipment of my 50PZ85U tomorrow via Amazon white glove delivery and they told me that they would not be turning it on to check that it works because it is below 50 degrees outside.

That made me wonder, how long should I wait before I do turn it on?

Thanks for your input.

When you think it has reached room temperature turn it on.

You can plug it in and/or turn it on as long as its internal temperatures are between 32-104. If it's not below 32 outside, you got no worries.

They're being unecessarily overly cautious. I've been turning my plasma TVs on at well below 50 degrees for several months out of the year over the past 3+ years without issue. According to the PZ85U owners manual, you can use the TV at anything above freezing so insist that they turn it on anyway.

From the manual:

"Operating Conditions Temperature: 32 °F - 104 °F (0 °C - 40 °C)"

If they refuse, immediately open the owners manual and show them the specifications page.

usually its to prevent condensation from causing a short especially if you've just gone from a very cold to warm enviornment.

Just open all your doors and windows. As long as the temp inside is the same as outside, you won't get any condensation!




Geeze, 50 degrees outside? Give me a break, it's only 26 here, and it will get down to 15 later this week!

My 58pz700 Panny was delivered on Jan 16 this year. the high temp that day was 36, the low 24 (I keep records ). They unboxed it, set it up, and turned it on. No prob. It is working wonderfully 11 months later, I am watching it now as I type . All this to say, make them turn it on, do not worry.

Really? So what experience do you have with electronic equipment that's been environmentally stressed?

Think about what happens to unprotected electronic equipment everyday. Digital cameras are exposed to temperature extremes all the time and they work. I leave my Ipod in the car on freezing nights and it works.

There is nothing to worry about, bring your TV in from the cold and turn it on. Thats what I did and mine arrived on a rainy 38 degree day.

As a person who wears glasses that regularly fog up in the winter when I come inside after spending time in the cold, low-humidity outdoors, this anecdotal evidence leads me to consider that it just might be possible for an electronic device which has been cooled off by being "outside" for quite some time to experience the same effect.

If my situation is time-critical, I might choose to over look this caution. If my situation is NOT time-critical, why not wait a few hours or overnight?

Operating Temperature: 32 - 104 degrees F (0 - 40 degrees C)
Operating Humidity: 20 - 80%
Storage Temperature: 14 - 122 degrees F (-10 - 50 degrees C)
Storage Humidity: 10 - 90%

Your Ipod and DC are sealed units and is unlikely to have any problems at low temperatures, but at high temps (a day in a black car in 100+ weather) I have had mine shut down.

If you bring it in and the humidity in the room is low you shouldn't have any issues with condensation. If you have high humidity in the room and your TV temperature is below the dew point, you could have issues.

Like you I have over 20 years as an electronics tech and have seen such accidents happen before to much more expensive equipment than a TV.

So what does a person do if a tv is delivered and it is below 32 degrees out? I will be ordering a tv within the next couple of weeks and it will be in the 20's I'm sure.

These are the facts, from the manufacturer, who conducted ESS testing of this display during development.

After considering these numbers, I would say, as a rule of thumb, if you take delivery of your TV in temperatures at or below freezing, let it warm a bit before power on.

Otherwise, let it rip.

As far as Ipods and non weather resistant digital cameras being "sealed units" their not and that's a fact.

ESS = Enviromental Stress Screening.

Electrical boards and certain parts of the board can accumulate condensation from cool to warm temperatures. It's best to leave the set warm up to it's environmental temperature before powering on.

Although the chances are slim that nothing may happen, the possibility of a short or any other related incident is always there given the right recipe in temperatures and in timing.

You know I don't really care how long you've been an electronics tech but when I had a supposedly sealed and safe lens that I paid $800 for do that when I went from a cool room in the 70's with high humidity to an outside environment that was maybe 20 degrees warmer and it died and had to be replaced because of condensation, I surely wouldn't spend thousands on a tv and let the same happen when I could wait an hour and let the tv warm up a little and not risk it.

Not to say it would happen but better safe than sorry and if it means an hour to protect an expensive purchase than so be it.

FWIW, Most specifications for non weather resistant CE devices state "Non Condensing" next to the RH spec, regardless of operating humidity level.

Put a glass of water outside for 30 mins. Bring it inside. If it condenses in the next 5 mins....So will the inside of a tv brought inside.

Usually 50ish is ok to set you above the dewpoint. However if there is lots of humidity inside your house, it may consense at 60 degress. Try the glass test to give youself a ballpark come delivery day.

I have seen uninsulated water lines pretty near raining running 40 degree water with the room temperature at 75.

Temperature extremes can also reveal cold solder joints in electronic equipment. I was more concerned with that than a condensation related failure when my TV was delivered on a 38 degree day. Since I actually induce/observe circuit failure everyday, using freez-it and a heat gun to reveal the location of said joints.

Poor soldering or excessive flux residue is a major cause of new equipment failure, especially considering that the flux residue can conduct small amounts of electricity.

Everyone tends to deduce that condensation must have caused their TV, Camera or whatever to fail after exposure to a temperature change. When in reality, it was cold solder.

I took delivery of a Panny plasma last week and it was extremely cold to the touch - about 32 overnight and according to shipping it was out for delivery at 2am so had been sitting in a freezing truck overnight. I like it warm in my apartment and had just taken a shower so there was a bit of humidity in the air - so I let the TV sit for an hour or so before I powered it and had no issues. Lovin' the Panny 42PX80U BTW.

I was only half joking about letting your house cool down before the delivery guys come, but I actualy thinks it's not a bad idea. Just turn off the heat and open a couple of windows. Maybe run your kitchen and bath exhausts too. Not only will it cool the place down, it should reduce the reletive humidity as well.

Just a thought, and probably what I'll do if and when I get my new plasma this winter.
