Any ideas? Having watched Freeview quite happily via a BT Vision box into an analogue TV, I've now installed a LG 26LG3000, LCD HD TV. All channels are fine except Sky 3; Dave; SmileTV; Sky News & SkySports News (both via the BT Vision box & the RF loop thru on the TV). These show as having 0 (zero) signal quality - although with 35-50% signal strength (in common with all the other channels). Signal quality on other channels varies from 45-100%. Interestingly, plugging the aerial lead directly into the TV and all's well! Presumably the two devices (BT box & TV) are draining the signal too much in some way? Any suggested solutions gratefully received!
