Having had my 42PD43000 for just over a year and being delighted with performance (especially DVD - superb) I have recently noticed random 'white speckles' in the picture at various times. It is more noticeable on the screensaver for the DVD player as this is a uniform dark colour, but also shows up on dark pictures as well. It is not particularly off putting. and mostly, I don't notice it unless I'm aware and look for it but it is there nonetheless. Does anyone have any experience of this? Is it a fault or is it normal? i've heard about 'dead pixel checks' - is this connected? If so what do I do? Should I contact my dealer who I bought from as the screen is still under warranty for another year? Thanks in advance for any help!
