Hello to everyone, I hope someone can help me in English :D i have a problem with this LCD TV Akai AZ 4280FHDT4 LCD 42" . It's power supply was fault, and I got it working, but now i have another problem, there is no picture. Actually the screen is fade white-blueish, no picture no OSD, but SOUND is working fine... I can't find service manual for this TV anywhere... And that is even more difficult because I cant see what is the main processor and the main IC on T-Con Board, because there is a glued cooler over them. The main board is:20-MT5362--13-OX The card that controls the LCD screen: SZTHTFTV1607 Power supply: MLT198TL I suspect the T-CON board, because i get 12V from main board going too it, but there is no supply for main processor on TCON (probably MST6xxx IC), there should be 3.3v to supply it, but there is not... there is i thin a DC to DC convertor that should convert 12 to 3,3 but i cant read any marks from it, so i don\t know what it does exactly. Here is what the board is, i think, it has its cooler taken off... http://download.szlva.com/QQ/ep/EP00041200118.pdf Here are the pictures of the tv set adn individual modules TV http://i50.tinypic.com/ifuc6g.jpg Behind http://i46.tinypic.com/2csf5mf.jpg Main Board (20-MT5362--13-OX) http://i50.tinypic.com/259wsok.jpg Power supply (MLT198TL) http://i46.tinypic.com/f2kkkx.jpg Others PNEL - T805A http://i48.tinypic.com/rb9xer.jpg AV/HDMI/USB modul http://i45.tinypic.com/eddg1.jpg SZTHTFTV1607 http://i50.tinypic.com/2m65n2s.jpg Remote http://i45.tinypic.com/2e4dlcl.jpg If anyone knows where can the service manual can be found it would be nice... I see that many LCD tv's have similar problems, and that the LCD driver is mostly the reason... Is there any similar manufacturer, that could help too... Thank you in advance

Sziasztok! A fent említett masina került hozzám azzal, hogy szép lassan elmentek róla a színek, majd már be sem tudták kapcsolni. Szétbombáztam, kapcs. rajzát innen Tanyáról letöltöttem. Kilazult alkatrész, vagy szemmel látható hiba nincs. A C303 kondin 300V-ot mérek. Ez a 300V egyen mérhető a táptrafó primer oldalán is. Szekunder oldalon semmilyen feszültség nem mérhető. A Fet mérésre jónak tűnik. a tápban lévő kontroller ic-n sincs tápfeszültség. van esetleg valakinek ötlete hogy is folytassam?

Hali. Delton,Jama,meg társai tv-vel küzdök. Standby sincs.Tápfesz 13volt,És ezen kívül semmit sem mérek. Már lekötöttem a 12,16,24 voltos ágat,függöt,a sort az opokör után,söt rövidre zártam az optót,de 13 voltnál többet nem lelek. Van ötlet merre keresgéljek? thx
