Typically, this powder can be wiped away with a damp cloth and doesn’t pose a health risk. However, if the powder consistently reappears after cleaning, it might be worth contacting the manufacturer or a service technician. In some cases, they might recommend replacing the back panel of the TV to prevent this recurrence.
So next time you see this white powder, you can rest assured it’s simply a byproduct of fire safety measures in your device. A quick wipe-down should do the trick, keeping your TV looking clean and fresh without any hassle.
