Hi,
I have just connected up a JVC 28" flat screen TV to a Grundig digibox (decoder). In parallel with the digibox I can still tune into conventional terrestrial TV channels as before. The problem is that with the digibox channels there is often a flickering of the picture - rapidly jumping up and down by a small amount. This can occur on a single channel depending on which camera shot is being shown. The flickering will turn on and off depending on the shot. The fault never occurs when I am tuned into a conventional channel (signal directly from antenna via co-ax cable), without using the digibox. I have tried all possible input sockets for the Scart, and also changed the picture display (mode) settings, but to no avail.
Any ideas what the cause might be, please?
