Sorry for starting a new thread but there were simply too many pages to search through in the TH-37PX70 thread to get a specific answer. I have had a Panasonic Viera 37" TH-37PX70 for 2 weeks now and noticed this afternoon 2 vertical green lines running the full length of the screen at about a third width in from the left hand side of the screen. This can get worse when purple colours are on the screen but ultimately revert back to the 2 lines. This is displayed on all inputs and sources and so I believe it to be the panel that's at fault as it also shows this line when the television informs you that there are new services available on DAB i.e. the grey background also has lines running through it. I immediately phoned John Lewis to inform them of the problem and whilst on hold the problem eventually disappeared (8 minutes). What I would like to know is does this problem come and go, or is it a case of people who have seen the fault can't get rid of it? John Lewis have arranged delivery of a new panel on Friday but obviously I can't demonstrate the fault at the moment.
