Default My TV has started 'posterizing'

I have a Philips 37" flat screen HD-ready TV which is about 10 or 11
years old. Of late, it's started posterizing its picture under some

[Posterizing is an effect available in many photo editing programs for
reducing the colour depth and hence displaying large patches of single
colours rather than graduations].

My picture isn't as extreme as that, and most colours are ok - but the
problem particularly affects (European) skin tones - and there are often
large green patches on people's faces and exposed arms, etc. People with
darker skins display ok.

The set is fed by an HDMI cable connected to a Humax PVR, and I wasn't
sure at first whether it was a problem with the Humax or cable rather
than the set itself - but when I replay old footage from my Android
tablet (which was ok at the time it was recorded) into the other HDMI
port, the problem is present on that too - so it's almost certainly the set.

Anyone care to hazard a guess as to the root cause? Is it likely to be
easily fixable?
