Hi!!.... I'm new to these forums and I'd be glad if someone helped me out....My Hathway HD set top box all of a sudden got really slow as a result of which there's no audio from the HDMI port..... It happened before and the problem was fixed when the set top box was fast again.... Restart fixed it before.....But it doesn't fix it now....I tried resetting and Updating the set top box...Both didn't work....One fix was to clear the NV RAM .....can anyone tell me how to clear it's NV RAM or does anyone know any other fix?.....Thanks in advance....cheers!!!
