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 CT-1407DT (chassis ?) képe sötét, kontraszt szegény MEGOLDVA!
Üdv Mesterek ! Teljesen kontrasztmentes a kép és sötét is ...Ha a G2 feljebb veszem látszik a kép, de idővel visszaszabályozza a fényerőt. AN5601K van benne nem találom melyik láb szabályozza a sugáráramot? Kis segítség jól jönne A 180K volt szakadt, ...én valamiért az utána következő 22k-stól ellenőríztem a vonalat. :) Köszönöm a segítséget mindenkinek!

AKAI CTW-2111 automata keresés távirányitó nélkül
Sziasztok!
Ahogy a címben is irtam, érdekelne hogyan lehetne 1uj csatornakeresést elinditani távirányito nélkül, azaz a tv előlapján levő gombok segítségével.
A távirányiton minden gomb müködik egy kivételével,  ami pont az a kék szinű gomb amivell el kellene inditani az autostore-t. Esetleg vmi megoldás ami magátol elinditaná az automata keresést, probáltam kihuzni az antenna kábelt majd visszadugni, de sajnos csak a már megjegyzett csatornák jelennek meg.
Vmi ötlet?
