If you want to protect your LED TV from any type of damage, there are several steps that you can follow.
1. When there will be too much humidity or moisture in your room where you have installed the TV you should not turn it on constantly for longer hours. Otherwise, it may damage your television.
2. It is recommended to install the TV where there is an AC so that there will be no functional issues.
3. Do not let dust and unwanted impurities get into the set-top box so that the TV can perform well. Also, when you are not using the television, you should not leave the TV exposed to dirt to prevent any kind of external damage.
