if there is sound and no picture could be a circuit board problem which could turn out to be quite expensive to repair due to the delicate work involved - had the same problem with mine and got it repaired but cost £ 300.00 which the dealer paid almost all off - if the tv is just out of warranty go back to the dealer and ask for an out of warranty claims form and fill it in as the manufacturer may be liable to pay most of the bill - dont let the dealer fob you off with no warrently nothing can be done etc etc - stick to your guns on it as I did and only had to pay £ 70.00 and also got an additional years warrantly. Hope this helps you x
