1. Poor Ventilation

The One Connect Box is very poorly designed in terms of heat elimination. When you store this unit in a closed cabinet with very little ventilation or a bookcase, your unit is very likely to overheat. 


Place your One Connect Box where there is proper ventilation. Most people prefer keeping it in a cabinet, in that case, make sure that the cabinet can support good air circulation.

2. Improper Placement

Some part of your house is hotter than other parts. Any spot that gets direct sunlight isn’t a good place to keep your One Connect Box.

Placing your unit close to a radiator or any kind of heat source is also a BIG NO. This will cause your unit to overheat for sure.


Make sure that your unit is placed in a place that is relatively always cool. Avoid heat spots to ensure that the One Connect Box gets to cool down completely after being powered off.

3. Dirt Accumulation

When your unit runs for a year or so without cleaning, you can expect a fair bit of dust to get accumulated. The amount of dust will depend on how dusty your home can get. But as a general guideline, cleaning your unit every year is a good idea. 

The cooling fan in your unit will attract the most dust and when the dirt sticks to the motor, you’re likely to get the overheating error message. 


You need to take the unit apart and clean it up. The control board and the cooling fan are connected with wires. So when you take out the control board be mindful to not pull too hard or the fan may get disconnected.

A paintbrush to remove the dirt from the control board is a good idea. You can use a can of compressed air to blow out your unit.

4. Broken Fan

The cooling fan in your unit may have gotten damaged. It could be the result of repeated overheating. A lot of users might reset their TV to bypass the error message temporarily, but this will damage the unit permanently. 


You’ll need to replace the cooling fan. It should be fairly easy to find a replacement fan online. You can expect a cooling fan to cost around $50.

Anyone with a minimum understanding of electricity and a light touch can probably easily replace the fan. So you don’t have to worry about the cost of hiring a mechanic.
