My wife and I decided to mount the HDTV on the fireplace, which we have painted white. We didn't want a bunch of black cables fraying out every which way from the set, so I have painted them white (them being the power cable for the TV, the fiber optic cable for the sound bar, the power supply for the sound bar, and a power supply for an ipod dock).
In the midst of painting the items, I wondered: would doing so cause the power supplies (the kind used by most, if not all, laptops) to overheat? Or even a regular power cable (like the cable used for desktops)?
Great -- I found some other forum questions pertaining to power supplies with vents and making sure not to get paint inside the enclosure, but these items are sealed as it is. I figured it wouldn't be an issue, but thought I should check with someone else.
