I have an old Samsung 58" Plasma (Model: FPT5884X/XAA). In our previous home, the TV was located in a large living room. I never experienced any heat issues as the room was probably big enough to dissipate heat better. In our new house, the TV was too large to go inside a recessed area over our living room fireplace, so it is in our master bedroom. It is sitting on a large piece of furniture (drawers) about 5" from the wall. Attached is a rough sketch (not to scale) of the master bedroom layout.
Our room gets unbearably hot when the TV is on for a while. We do have a fan in the bedroom and we have one HVAC unit for the entire house (~2000 sq ft). It's located in the unfinished basement and the thermostat is on the 1st floor. Our master bedroom is on the 2nd floor along with two other bedrooms. The 2nd floor is usually a little warmer than the 1st floor, as one would expect, but not much different. The master bedroom, though, is much hotter than the other 2nd floor bedrooms and hallway. I can only attribute that to the TV as the room feels fine when the TV hasn't been on for a while. You can feel the tremendous heat radiating off the unit when you put your hand by it.
Now to solutions. I know I could install a damper just outside the HVAC unit in the basement on the ductwork that feeds the 2nd floor. But, that would just help even out the slight different in temperature from the 1st floor as it would make most sense to locate a new thermostat in the 2nd floor hallway. Plus, if I did put the thermostat in the master bedroom, the other parts of the second floor would be freezing as it would be taking the temperature of the master bedroom with the additional heat from the TV. Another solution, which seems comical, would be to get a more efficient TV. I know if I got a newer LED LCD, it would probably make a big difference as it would be more energy efficient and put out less heat. But, I don't want to get another TV unless I know it would help.
Anyone experience similar issues? Does anyone have any suggestions for solutions? Thanks.
