I have a 42PFL5604H TV and whenever you turn the TV off and back on again soon after then the sound stops working. So you then have to switch the TV off and wait for about an hour or more before switching the TV back on in order to get the sound working again.

I noticed another closed thread on the forum related to the same problem but with no solution given (http://www.supportforum.philips.com/...ght=42pfl5604h).

Has anyone else had this problem or know how to fix it? Any help would be much appreciated as it's a very frustrating problem and seems to be getting worse.

(Sound is playing through the internal TV speakers by the way.)
