Why does the picture from our Tivo box keep going shades of blue ? Putting it into standby and then coming back out of standby seems to sort the problem for a few days. Doesn't seem to be any pattern to it.
Don't think its overheating, as its on a open shelf by itself and it doesn't feeling any warmer than normal.
Normally the scart isn't connected I only connected it to see if it resolved this problem, the Tivo is normally only connected by HDMI and the optical connections. The box has had several reboots whilst having this problem.
