• Hi all,im still having a problem with my 500T. Cant get it to scan one frequency.One person suggested going 5mhz either side of the frequency and turning off the 5v supply.Which i did, still cant get it to lock and sync.on this one frequency. A friend of mine got a new 500T today and he has the same problem as me.I think it must be a tuner problem. any help much appreciated
