Why my internal tv tuner is not working in window 7
First thing you need to do is to check the brand and model of your internal TV tuner.
You can do this by knowing the motherboard you have or you can try to check under device manager.
There is a possibility that the TV Tuner you have is not compatible with Windows 7 or it doesn't recognize a correct driver for your TV Tuner.
One easiest thing is to contact the computer manufacturer and ask them about the driver for your TV tuner for Windows 7.
