I purchased a HITACHI LCD TV (60V500) in 2004 and in 2006 I started noticing a red glow whenever the screen is blank (between commercials etc). I reported the problem to Hitachi's customer service dept and they told me to try replacing the lamp. I did so but the problem did not go away. After doing some research I now find out that the Color engine in these units are poorly ventilated which causes the unit to over-heat. I tried contacting Hitachi to have them replace the color engine which will cost approx $1, 400. They refused saying the TV is "out of warranty”. I also found out that they have been selectively replacing some color engines with refurbished ones. I think this is a problem which they can easily take care of by providing refurbished color engines and have the customers pay for the repair. Until then I am staying away from the Hitachi products and suggest that you do the same.
