Sziasztok
Kerult hozzam egy Sony Bravia KDL-40R550C LED TV, azzal a diagnozissal, hogy hatter hibas.
Ez elvilagitasos TV, de szerencsere meg nem rendeltem hozza LED sort.
A TV bekapcsol, hang van, hatter vilagitas van!
Kep nincs semmilyen. T-CON-ra gyanakodtam, de mar nem vagyok benne biztos.
Ezeken eleg gyakori a kondi hiba. Nem talaltam zarlatos kondit, de feszultseg alatt is meregettem.
Lehet van olyan feszultseg ami kimaradt, de a tap 12V, a 3.3V, a 1.8V es az 1.2V biztos megvan.
Mellekelek par fotot a T-CON-rol, elegge darabokban van, de legalabb lehet nagyitani.
Valahol olvastam, hogy elfordulhat hogy firmware hiba, le is tudnam tolteni a firmware-t, de nem tudom, hogy kep nelkul hogyan tudnam elinditani az irast.
Az alaplap egy Mediatek processzoros csoda...
Kerlek, segitsetek ennek a problemanak a megoldasaban.

SONY KV-29X1D (részletes)rajzra lenne szükségem sürgösen!Tünik el a kép,hang van.Ilyenkor a képernyő elsötétül és néhany masodperc mulva helyrejön.....majd ismételten ez történik.
szép estét mindenkinek
Adott a fenti TV bekapcsolás után egy pillanatra a nagyfeszültség megjelenik és letilt mindent még a standbyt is meg kell várnom mire kimegy az áram a TV-böl hogy ujra tudjam tesztelni.
ha a sorvégtranzisztor és sorkimenötrafó közé berakok egy izzót a tv bekapcsol van hang válthatóak a csatornák.
Remélem tudtok segiteni.

Hello
The TV does not show any sign of life , I started the troubleshoot as this , no power Led, no reaction when pressing the power button.
I checked the Power coming out from the power supply, the 3.3V_standby is correct and steady, then I checked the 1.2V_standby produced by IC6001 which Is good as well.
So I decided to control the main IC , IC4000 , he does not output any oscillation on the Xtal, Then I am now bloacked there.
The schematic is downloadable on this website , the schema is weird because the processor is not represented with any Xtal output, but obviously it has one.
Thanks you for your hint and help.
