Sony KDL-40R470A háttér hiba
Sziasztok a tárgyban szereplő tv-ben cseréltem hátteret. Az új  háttér teszterrel megy 132v-al. A tv viszont nem indítja be a kimeneten csak 76,5v ad ki. Rajzot nem találok hozzá, hogy mennyinek kellene lennie. 50db 3V-os led van a háttérben. Nincs rajz valakinek hozzá?
Köszönöm Balázs

Sony KDL-37EX402 the TV in dead, no LED, motherboard problem.
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.
SONY AE-5A , TV-n a nyomógombokra nem reagál
Sziasztok! Van itt ez az otromba nagy (meg legalább 100 kilós) CRT TV, aminek geometria hibai vannak V,H,párna. Bele szeretnék menni a szervízmenüjébe, de ahhoz hogy ezt megtegyem elôször le kell nyomnom a TV elején a P+/P- gombokat. De sajnos nem reagál rá, pedig a nyomógombok jók, a drótokon eljut egészen az alaplapig.Elöl van még a VOL+/- arra se reagál, megy egy tápfesz is fel az is megvan. Raktam bele másik eprom tartalmat,üres epromot is, de semmi sem változott, egyedül most nem párna befelé van, hanem hordó.H és V maradt a rossz (kicsi). Most akkor hogy menjek be a szervíz menüjébe :(
