Last night, I noticed an issue with my Tosh 36ZP18B that I don't think anyone has commented on before. In summary, the AV pass-through feature doesn't seem to work when the TV is switched off. I have my Sky box attached to EXT1, my video to EXT2, and the EXT2 output set to EXT1. Hence, the Sky signal is relayed through the TV to the video without having a dedicated cable between the two boxes. Nice feature, I thought, saves on cabling. However, after several recordings from Sky ended up as an hour's worth of blue screen, I found that the pass-through only works when the TV is actually switched on. As soon as you switch the TV off, the video loses it's Sky signal. Switch the TV on again, and the Sky picture appears on the recording again. Now, in my mind, the pass-through should work whether the TV is on or off. Am I wrong? Is there something else that I need to set up? Do any of you have the same problem? It's not a huge problem as I can always add a scart cable between Sky and the video, but it's made me curious. Nigel.
