I have a Phillips 32" CRT (not sure of the model - it's about 3 years old). A year ago, after connecting up a DVD recorder to it, it developed a volume problem. For example: if the DVD player was on and the Sky Digital was on standby, the volume would turn itself down until it was muted (even with the sound all the way down the remote sensor on the front of the TV would still keep flashing, like someone was using the remote control to turn it down). I got around this, but lately the volume has been going down every now and then even if the Sky is *on*. Now the problem is permanent, and the sound just wont stay up. I've even unplugged everything so that all that's connected to the TV is the Sky box. The volume just wont stay up, although it does have moments where it's fine for a minute or two. Is this an obvious problem with a simple solution? In the past, turning it off and on again cured it. But not this time. Any ideas would be gratefully accepted!
