My TV has a 3 pin male port on the back labeled "service", which looks identical to a port you might plug a computer fan into, but when I tried plugged a 120mm fan into it, I found that the port has slightly different dimensions and therefore isn't the same as a standard computer fan port. Does anyone have any idea what type of port it is? It is right next to a powered USB port also labeled "service" that I use to charge my cell phone (even though I probably shouldn't ;D )

Thanks
