Windows 7: Sound but no picture.

26 Oct 2013   #1

Windows 7 Home Premium 64 bit. (On both machines)
 
 
Sound but no picture.

I have a strange problem with WMC, which starts OK but when I choose a channel via the EPG, sound works but no picture, on any channel. If I then go down or up the Guide to another channel, it works perfectly. go back to the original channel (or any other) and it all works fine. This happens for any two channels. Not a really big hassle I know, but annoying. It was working fine until about a week ago, when this began. I have reset the Channel List, retuned the TV (from a PC tuner card - see my spec's) and checked the antenna/coax, which is connected to a junction box (not boosted) in the loft, shared with the main TV in the lounge, two rooms away. This was fitted over a year ago by a qualified TV engineer, a mate who lives in the village. The signal was checked at the cable end and found to be at full strength. The Tuner is Freeview.

Occasionally, on some lesser channels and sports action such as football, pixels break up slightly and reform instantly. There have been no software or hardware changes.

EDIT: Just updated drivers to V.7 2.8a. No difference.
