Hello friends,
my SONY TV shows some missing LEDs I think:
After dissabling and measuring: The first and the last two transistors show 1,6 Volts. The second one shows 0 Volts:
Any ideas?

Üdv!
A címben említett TV-vel kapcsolatban lenne problémám.
Menet közben teljesen leállt, majd a készenléti piros led is kialudt.
Szétszedve sem égésnyom, sem púpos kondi nincsen. A standby 5V viszont nincs meg, csak 2,2-2,5V körül ugrándozik, gyanítom, hogy ennek a hiánya miatt állt le a fő táp is.
Sajnos rajzot nem találtam róla.
Ilyen a tápja
Sziasztok !
SONY KDL-50W829B
Háttérvilágítás, és hang van, de a kép eltűnt, a saját menüit sem jeleníti meg .
Lett beletéve egy másik T-con panel .
Firmware frissítés USB-ről, elvileg sikeresen megtörtént .
Maradt viszont öt piros villogás .
Innen már gyári resetek tömkelegével se tudunk továbblépni .
Ehhez kérek ötletet, vagy segítséget, hogyan tovább, hogy "talpraálljon" a rendszere !
Köszönöm !
Üdv.
Astra
