Anybody who has bought a Samsung LCD tv in the last few years and is having problems with it not turning on or making clicking noises when it tries to switch on can get it repaired for free by Samsung, even if it is out of warranty. Mine started to go wrong a couple of weeks ago. I had the clicking problems and also a green overcast on the screen. I called Samsung and it was repaired within 3 days free of charge. Call 01932 454358 Samsung. The engineer said the fault is because the wrong components were fitted to the televisions in the factory.
