Has anyone experienced the following symptom with a Hitachi plasma 42PD6600
or for that matter any other plasma set?



Pinky red shimmer or haze appears over some of the darker parts of the
picture. The fault is present on all the scart inputs, computer input, and
uhf channels. The fault was initially intermittent and occasional, but now
is pretty much annoyingly present all the time.



The set is now just out of warranty, so I would like to first try fixing the
fault myself.



Many thanks.
