Ive have a plasma 43" TV for approx 10 years now and all of a sudden it kept switching off. I was told by everyone I knew "throw it mate its not worth repairing" etc. Took it to an Indian chap I knew who does exactly this and repaired the TV plus changed a sound board and charged me £40 and gave me a 3 month warranty. Got the TV back and the sound was never this good when new!
