Hello was wondering if anyone can give me advice. I'm not sure if it's called screen burn or dead pixels. But I've had my toshiba 55ul5a63db TV now for 15 months now and noticed the horrendous black marks top left and middle well all over really. Toshiba says its only 12 month warranty any advice to try get them to repair it?I'm so angry surly you wouldn't expect it to be like this already. Really should bought Sony but I'll learn. Ignore the writing in screen think the camera was just to quick. Thanks in advance people. Stay safe.
