akai ct-2107dt av probléma
Sziasztok. A fenti készülékkel az a gondom hogy nem igazán vált át AV-ra. A készülék TV módban rendesen müködik,ha rádugok pl egy DVD-t kép elmegy, ha átkapcsolom az előlapon AV-ra hang van a kép törik. Amikor nincs az AV bemenetén semmi rádugva és átkapcsolom AV-ra nem egy tiszta kék képernyő van,hanem egy zavaros kép.

AKAI CT-2107DT tv, hang probléma
Tisztelt kollégák segítséget szeretnék kérni. Van egy AKAI CT-2107DT tv készülékem, de az a bajom,hogy rettenetesen halkan szól valamelyik csatornán nem is lehet a hangját hallani.A képernyőn látható,hogy a visszajelző csík megy rendesen oda vissza. A többi funkció rendesen szabályozható.Tisztelettel javítási tippet szeretnék kérni. Előre is köszönöm.
Akai AZ-4280FHDT4 LCD TV 42", Has sound but has no picture
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... Here are the pictures of the tv set adn individual modules TV Behind Main Board (20-MT5362--13-OX) Power supply (MLT198TL) Others PNEL - T805A AV/HDMI/USB modul SZTHTFTV1607 Remote 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
