TV flickering

Our main TV a Samsung LCD model, recently, I noticed when backgrounds are very dark (such as for example "Who wants to be a millionaire") there is a pronounced flickering it pretty much started when TV companies begun broadcasting HD on a regular basis (which I'm not using) Looking closely shows that on lower contrast backgrounds it happens as well but is not so noticeable.
Initially, I thought it was picking up reflection from an adjacent fish tank air-driven water agitation and the lights, but has been discounted since it happens with the lights off.
The TV is around 8 - 10 years old and has a pretty hard life as the disabled Mrs Petlew watches it for most of the day. Should I consider it is ripe for replacement, or could this really be to do with HD and will still happen with a new TV..
Experience; is something you gain, just after you needed it most.

When faced with two choices, simply toss a coin. It works not because it settles the question for you. But because in that brief moment while the coin is in the air. You suddenly know what you are hoping for.

Re: TV flickering

Is there some sort of black compensation or dynamic contrast active on the TV?

I don't think so.

Re: TV flickering

@RPMozley, I checked, and that's a no. But thanks anyway.

Re: TV flickering

Checking the manual, in the "menu/picture" section there was an option "digital noise reduction" which was switched "on" I switched it "off" which frankly seemed the wrong way round to me but, I think it has made some difference, but its very difficult to tell in broad daylight as the flickering is most noticeable in a darkened room after dark. I'll let you know tomorrow.

Re: TV flickering

Although I'd have expected it to show more on light rather than dark picture backgrounds one possibility that springs to mind would be the backlight lamp(s) starting to fail.
Most older LCD TVs use compact flourescent backlights of some sort and at this kind of age they can start to flicker (usually starting at the ends of the tubes) just like normal flourescent tubes - it could also be the inverter that drives the backlight failing.
At this age you may well decide that it is not worth a repair (no idea of the likely cost) - a new LED backlit TV should be significantly less expensive to run so may well be the best option mid to long term.
