Polaroid is the other non-brand name products, made in a limited quantities and used well known logos as a bait for consumers. Those are: "element", "mag', "magnavox", and polaroid itself. the only one advantage of early "polaroid" is: display panel has been made by real Polaroid, then. what made the picture quality outstanding, compare to other "bunch". even though they use similar hardware and design. Many real Polaroids were junked few years ago, due to inability to get any product support: i.e. hardware for a reasonable price. that's why you have got into the problem: there is NO support for the product, not even "factory exchange only"! That's what we, the Repair Men, find at the 'parts distributors". Those must be sitting on direct payroll from People's Republic. They trying to price replacement parts well above the cost of new unit. Example: 52" Sharp LCD panel cost: $2,695.00 plus s&h! and that's for 5 years+ set! Make up your mind about 'support" and start to repair your set. In most cases it will be very reasonable, especially if your set was your 'baby". don't try to replace it now: closer to the date, TVs are becoming more and more "toys"! Built to break! how would you support growing economy and wealth of those "people's republics'? By robbing yourself of the daily pleasures!
good luck in your discovery,
