This is a remote control for the Comtec WGA8000 and L&V LV-DT4400 digital terrestrial tuners. All buttons respond and the red light turns on, but when checked with a cell phone camera, no infrared light is emitted. The infrared lamp seems to be slightly detached from the circuit board, as if the solder has come loose. For those who can repair it. This is a junk item, so returns and refunds are not possible.
