Well i tried calling a few tv repair men to see if they had heard of this problem and most of them just said bring the tv in so they can have a look. They say that they dont know what type of tv it is until they open it up, in my case it was a Thomson model. I'm a cynical person and dont like the idea of leaving my tv thinking they will find something trivial but charge alot so i found two guys that do house calls. Fisrt said could be the tranformer and would cost over £100 but he was stumped by the error sequence 3:7--was not in his notes. Second man(really good) came in and by that time the tv was going through so many light sequences 3:7, 4:5, 1:2, 2:7. He got straight in there and didnt bother with these error codes explaing that its the tv' safety mechanism to shut off saying something is wrong but with such a variation in codes its not accurate and consistent. He took out the main board and located a capicitor where the solder was loose, he said the capicitor itself looked ok but changed it just incase--resoldered it in place and any other potential looking loose solder. Worked like a dream and cost me total £40. His name was Ken Brown located near Glasgow. Honest guy.
