Before spending a lot of money I have been looking at various LCD and plasma screens recently and have noticed on several models LG and Samsung in particular that where the power LED is located that the heat (from the tv being on all day) has caused the seal of the screen to melt, resulting in a sagging band dipping out below the frame. Is this a design fault? Has anybody else noticed this as about 7 or 8 sets in my local store where all suffering the same defect - even the new 60" LG set costing £2199!
