I bought a Insigina Plasma 42 " inside is all samsung circuitry This model is a Best Buy brand were as Prima is a Future Shop brand as fate whatever would have it ours were identical in ever way even to the remote size shape button assignment both failed within 18 mouths and as made in China they did not send the modular replacement boards. I don't suspect this chip old or knew is involved but at $2000.00 it would be nice to have a fix other then the land fill.
That happens when you buy "cheap", like Insignia or Prima.....
