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... 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
Akai TV2861TN--MX71B6
Tegnap valami történt a fent megnevezett tv típussal, magától összeugrott a kép a felére kb. Elkezdtem nézelődni a neten és megtaláltam a szervice manualt aminek hála sikeresen visszaállítottam a képet. Eddig nincs is semmi gond de addig piszkálgattam hogy sikeresen el...tam. A gondom az hogy belenyúltam a service adjustmentsben a bináris beállításokba és sikeresen megváltoztattam a UIF FLAGS ----->Logo bit-et. Ennek következménye hogy nem tudom újra előhívni a menüt hogy átállítsam, mivel bekapcsolás után fekete kép jelenik meg. A kérdésem az lenne mit tudok tenni ilyen esetben. Újra kellene írni az eeprom-ot????? please help köszi És milyen úton tudom újraírni az eeprom-ot, csak eeprom égetővel gondolom?????ezt csak azért kérdem mert van a tv hátoldalán egy service csatlakozó csak nem tudom hogyan müködik...???? Köszönöm.....megpróbálom egy üres eeprommal mert nincs égetőm......Remélem mükszik majd :D

Uraim, A tv-n gerjed a kábel adások 70%-a (az ügyfélnél is és nálam is). Már tunert cseréltem benne de a hiba maradt. Se melegítésre se hűtésre nem változik.. Találkozott már valaki hasonlóval? Üdv Komlós Laci
Akai CT-G215DT képeltérítés?
Sziasztok! Ezzel a tvével az a gondom, hogy eddig rendesen működött csak néha leált az eltérítés, cseréltem az összes elkót a körben, KH hiba megszüntetve. Most meg olyan lett a kép, hogy alul jó, de a teteje nyomott lett, és a felső 10cméter pedig FFérben adja! Most merre keresgéljek eltérités, vagy a dzsungel ic körül?
