Hi guys, after receiving the replacement set from powerhouse, it seems this set is suffering from the dirty screen issue. I've tried using a hairdryer to displace the colour which is does do and it spreads it around. I make the circles with the hairdryer bigger and bigger and slowly away from the screen and switch the hairdryer off and still the "stain" remains. I've tried degaussing the set the set from cold (i.e switching it on with the power button on a cold start) but yet the stain still remains. It's very noticeable on pale backgrounds. Is there anything you guys can recommend? I don't really wanna have to take the set back because I've now got a picture i enjoy. In addition the contrast isn't too high. I realise it is probably caused by a magnetism problem but I can't seem to get rid of it. Oh the set is a Sony Wega KV-32CS70 Cheers guys.
