A friend of mine bought a Phillips Plasma 3 years ago for 3 grand, recently it went pop.
Every dealer he contacted said he would have to contact Phillips as they won't let uncertified dealers have the parts.
Anyway, he contacts Phillips who tell him that they will repair it through their agent, asked how much it would cost, Phillips said depends what's wrong but will be £420 for collection/delivery plus whatever... after creating hell on the phone for hours they eventually agreed to a total cost of £690, including collection/delivery. Last I heard he had found a local dealer who said he would have a go fixing it for £450, as far as I know it is still lying in bits in the dealers workshop.
