2 x LG 42PC1D/A - red speckles on screen

[E Parton]

Hi friends ..
I have 2 LG X3 panels showing the same fault ..
These are not repairs but are in fact 2 plasma TV's owned by myself and my father
He has the 42PC1D and I have the DA version .
The sets are less than 2 years old ..and were bought from 2 different sources within a month of each other.
The problem is that there are red speckles appearing on screen particularly noticeable in dark areas of the image .
I also use my mine as a pc monitor on my HTPC .
Typically these speckles can appear to 'follow' the mouse curser as it moves ...leaving a trail of red speckles in its wake ..
..these then gradually subside..
The area of the sceen most affected is top and middle of the dispayed image....one both plasmas.
I've done a bit of digging on the net ..and it appears this is a very common problem and some claim to have improved the situation by pot treaking on the drive boards.
I suspect this is a plasma panel showing signs of ageing ...but at 2 years old it certainly isn't much of a recommendation for LG.
I believe the correct terminology for this 'effect' is mal-discharge ...and Im also informed that it can be disguised though not cured ..by writing new firmware to the control board .
However this would require specialised equipment not generally available ..even to the trade (unless you are an agent that is)
I must confess I feel a bit cheated by LG ...and of course I have no comeback as ...being trade...I didn't extend the basic warranty beyond the statutary 12 months ..
Has anyone else had this problem ...and solved it ?
Any info on this issue would be greatly appreciated.
