Dear forum members, Perhaps anybody can help me with the Sony KDL-40EX1 TV set. I have this set here for repair , but I have no experience with this type of TV. It has a media box and sents the TV information wireless tot the TV. My problem is on the tv: no picture and no sound , the backlite works because I see white light behind the screen. There is also wireless communication because I can turn the TV on and off with the switch on the media box and on the TV itself. I have the service manual but this doesn't really help me any. So the power board seems to be working because I have high voltage for the ccf tubes and 12V for the rest of the TV. It is my idea that perhaps the main board is defective because I have no picture and no sound but I am not sure. Is there anybody here on this forum that can help me with some idea's. Thanks Fred Dijksman

Sziasztok!A fenti tv kb fél perc után kikapcsol.Ezt 3-4-szer csinálja majd majd 9-et villog a készenléti led.Az error kódba nem találok 9-et villogó hibát.Av-n van képe de analóg állásba nem tudok beállítani semmi adót.Nem volt valakinek ilyen hibája?

Sziasztok! Szerintetek is t-con probléma a képeken látható jelenség? A kép több órás üzem közben jelentkezett és konstans. Se hideg, se meleg, se fizikai hatásokra (pl. lvds kábel mozgatása) nem reagál. Esetleg gamma korrektor, vagy main hiba? Előre is köszönöm! Z
