I have researched this problem and it is so common we that own this piece of junk ought to form a class action suit and sue. It is caused by a bad part or bad connections to a part called a backlight inverter. It seems the LCD needs a higher voltage than supplied by the 12vdc power pack so this part re-chops the DC voltage to generate the LCD requirement.
The date of manufacture is on the back of these TVs and all the problems seem to be from those made in 2006 to 2008

If they are visable when the set is off then I would have to say yes there is moisture damage to the LCD panel itself. If visable only when turned on then you have a faulty LCD panel.
