If you buy a new TV in winter, you have to be careful: The temperature difference between indoors and outdoors could damage the device – at least that’s what the myth says. atechbook asked TV manufacturers what the truth is to the rumor.
Anyone who buys a new TV would prefer to set it up immediately in their own living room and try it out in detail. But then the surprise: The supplier points out that you should wait a little longer before connecting the set to the mains until it has warmed up to room temperature. Otherwise, there could be damage to the pixels. But is that really true? Should you really wait until a new TV has warmed up to room temperature in winter? atechbook wanted to know what the truth is behind this myth, which is also discussed time and again in tech forums on the Internet. We therefore asked the manufacturers.
There is no danger for the Pixel…
In fact, the concern about damaging the pixels is unfounded. ” Generally, Sony TVs can be put into operation right after delivery and setup, since a short-term temperature difference has no effects. So the supplier’s advice doesn’t apply to Sony TVs,” explains a Sony spokeswoman when asked by atechbook. In fact, the TVs can even be operated in cold rooms. D he cold can cause smear marks in the picture, but this is not a failure of the pixels. If the TV returns to warmth, the picture will also return to normal.
Samsung confirms this statement. After consulting their technical team, a spokesperson explained that there is no danger for the Pixel by switching it on too quickly.
The rumor that televisions could be damaged in the cold of winter could be due to LCD displays. LCD stands for liquid crystal display, and in such screens, liquid crystals provide the image on the TV. Perhaps the idea that these liquid crystals can freeze like water started this rumor.
… but for the whole device!
However, the danger in winter also does not lurk specifically in televisions, but in general the cold temperatures are a challenge for technical devices. Both the LG and Philips spokespersons said that the pixel myth is wrong in itself, but that the advice to be careful with cooled technology like TVs or smartphones in winter is justified. The danger lurks in condensation.
“Air condenses on cold objects when the ambient temperature is suddenly raised, resulting in water droplets or a film of moisture. This process also occurs on the outside and inside of electronic devices,” explains a Philips spokesperson. ” On the circuit boards or on the contacts of the interfaces, the moisture can then lead to leakage currents and short circuits, which could damage components.”
Caution also with laptops and smartphones
So if a TV spent a night in a cold warehouse in the winter and is brought into the warm, moisture can form on the circuit boards. And this applies not only to televisions, as a spokesman for LG explains: ” Basically, the tip is not wrong for all electrical devices, because condensation moisture, for example, can always be an issue. That’s why you shouldn’t leave your notebook or smartphone in the car overnight – regardless of the risk of theft – and then switch it on directly in a warm room in the morning. That’s because bringing the device into a warm room creates condensation moisture that can damage the device.”
Therefore, the tip: Technology that has spent a night in a cold car, on the loading area of a truck or in a warehouse can suffer from condensation if the temperature difference is too large. For new devices, it is therefore actually advisable to let them warm up in their packaging first, protected from moisture, before unpacking them and connecting them to the power.
