This was a great item, but all in all it worked for less than 4 months. I purchase it from teachforless.com.
my system is Vista Media center, Gyration GYR3101US is not working today.
I changed batteries and reset the receiver but it didnt help.
In pc mode, the green light will flash when button pressed, but green light on receiver is not flash.
I don't know why, I try this remote on another computer, still not work.




Can anyone help me ? thanks in advance.

Could be RF noise... but it could also be that either the RF transmitter or RF receiver has died. Unfortunantly the best way to test that is with another pair of components!
