It has been working satisfactorily for the last two years or so. Nothing has been touched or changed, so it must be connected correctly - except that yesterday it failed to connect the two components, as described in my original message.
As per my previous reply, nothing was changed prior to the sudden failure the subject of my original question. Are you able to suggest what might have occurred to cause the problem? It is clearly nothing to do with the connections, which have remained untouched - so what else might it be?
Sorry - I omitted to say what type of connection is used, as you asked.
It is SCART.
Have you received the information I sent late yesterday, in which I informed you that I had solved the problem?
This is a very condensed version of the lengthy message I sent to you yesterday evening. I can't understand why you have not received it.
The problem is solved. There's a switched splitter box in my system to separate the DVD and Humax box signals. I tried bypassing this and the problem was solved. Seems like I might need a new splitter box.
