Mitsubishi WT-46805 46 in. TV

I was so excited to move into my new house, so 2 months before i move in, I already purchased this unit at " The Wiz " and gave them an estimated delivery time, also at that time this Tv was on sale, after moving in and the Tv was delivered,it really fit good in my family room, since i only have a small family room (16 x 12), I plugged in my dvd player and pop in rush hour 2, the picture was sharp and very clear. i got this Tv last November, since i have 2 more Tvs', I only used this Mitsubishi unit to watch dvd's on weekends or sometimes a movie for the whole weekday, around january while I was watching the screen completely went green, I can still hear the dialogue, so I try to read the manual to see if there was an adjustment for this , nothing stated, so I turned it off, after couple of hours I tried again then it was okay , after a week time it happened again,this time tv was out for 3 days, then I called their customer service, they sent service men but couldn't find any problem because when they came the unit was fine. the service people came 3 times to my house replace 2 parts ( for a 3 month old tv )then finally decided tv cannot be fixed. after suffering from late January to May (almost 4 months with a defective Tv), with endless follow-ups Mitsubishi finally sent me a new unit.
