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
RECOR tv sorvég "elfűt" (ez speciel Audioton, de monthatnék Akaiwa-t vagy Panascanicot is)
Üdv' Mindenkinek! Sorvég zárlat, kiégett 470n láb, mondom, csak ennyi? Hát nem! Tápban szinte kapacmentes elkók, BUT és egyéb tranyók zárlat, meg a szokásos. Sor megépít, táp megépít, megy de töri a képet. Kf felkondiz, tök jó, Hallaluja! Erre másnap hív a gazda, hogyaszongya: fél óra után tör, majd gyűr, majd vízszintes csík és szag. Végre kikapcsolta, (egyszerű lelkületű bácsi, a javítás előtt is mondta, hogy hetek óva sikítva-zümmögve indult, kérdem én mért nem szólt, mire "azt hittem a kis lámpa mellette", szóval rendesen megfőzte a gépet), fél óra múlva próba és megint megy negyed órát, aztán gyűr, szag stb. Nem láttam még ilyet, hétfőn hazahozom, addig várom a tippeket!
Akai Let32fhd3283 semmi életjelet nem ad
Sziasztok! Adott a témában említett "csoda". Semmi életjelet nem ad, standby sem világít. Az összes kondit cseréltem benne, a nagy pufferen 314V-ot mérek. Valakinek valami ötlet? Esetleg működőképes alaplap is érdekelhet, de jobb lenne megjavítani.
Akai let40fhd4080 firmware keresek
A tárgyban említett tv csak akai logóig jut.
Van esetleg valakinek mentése hozzá?
Köszönöm Balázs
