[QUOTE="revjames, post: 503973, member: 5256"] No its no good, tried to polish scratches out but thats taken off some kind of coating so its toast. However, I have learned a huge amount about these kind of TVs and know how to test for backlighting etc and prove the backlighting with tester before ordering replacement boards etc. Don't know if its cost effective where you have to remove the bezel and the LCD panel and diffusers to get to the LED strips. I won't go looking for TVs to fix but at least when they do come along I'll be more keen to have a go. I have had a considerable amount where the problem is simply a 20p diode. [/QUOTE]
