DON'T SEND THIS UNIT BACK! IT IS ABSOLUTELY THE BEST DLO ON THE MARKET! All you need is a software upgrade for your tv. Unlike other manufactures that make DLP tv's that aren't upgradeable the Mitsubishi is! Ask your sales person for the version 4 upgrade!
I have the mitsubishi 52725 dlp. Absolutely love the picture. The 1st unit we had locked up and also got a green vertical bar screen. The dealer replaced it but unit #2 also seems to lock up periodically (but without the green vertical bars)
Are others out there wuth Mitsubishi 725 and 525 models also having their TV lock-up? After reset, it works fine. My dilemna is do I send back the mitsubishi and get another brand - or is this a software glitch Mitsu will eventually fix?
Thanks for any help. Don Boy
