I have encountered this before---there are set top boxes that will convert the NTSC to PAL and the only other concern is the line voltage being the same or not.

Yes,France and UK are in Europe an both have the same tv signal broadcasting out channels that PAL frequencies output.So yes.

Unplug,replug the tv about an hour later,let the tv reset itself.Tries goto tv menu,go to AUDIO,go down to reset the audio setting,back to factory setting.Goto menu to PICTURE,go down to reset,to resetting the Tuner board back to factory setting.The sound,should be there,now all the time.Not,than the Tuner board have problems.That the board,where the broscasting signal cable plug into it.That the Tuner board.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish Tuner board for the replacement.

Sorry to say but it sounds like your power supply is bad, although it is possible it is some other components in the TV because turning it off allows all diodes etc to power down completely. Unfortunately after a bit it happens again which leads me to believe again power trouble.

1.This issue sounds as though the TV connection circuit has an issue.
2. You have changed the DVR and the HDMI cables and you still have an issue with the video (pink screen) indicates a video circuit issue ( improper voltage or current) at the video section of the circuit.
3. This will require some troubleshooting by a qualified tech.
4. To make sure, try connecting another properly working LCD TV to the cable box or DVR an check.If you get a picture and sound properly it is the TV.
5. Usually a cable box is QA'd (quality assured) by the company and will not be sent unless tested 1st

try checking your connectors on the back,if your using hdmi,try scart,if your using scart change the lead or try tv on component connection.
