Re: black coal
I have a Mitsubishi (not black diamond) since 1998 and last year the picture went.
When I rang the t.v. repair man he asked me how old it was and if it was a black diamond, when I told him he said 'good' and that he should be able to fix it. It was a small part and cost €40 including labour.
I asked him about Mitsubishis and he said that my telly should go for years as it had been made in the far-east and were of a very high quality. He said that the black diamond ones are made in Turkey and are not of a high, even good standard and that he wouldn't touch one even to fix it as they were so unreliable.
My telly is still going over a year later, as good as ever.
