Sziasztok!
A https://elektrotanya.com/content/philips-40pfl7007k12-does-not-power-chassis-qfu11e-la
oldalon leírtakkal szemben a készenléti piros LED csak egyszer villan fel. A 1M95 csatlakozó 2-es Standby-on 0V van kb 1 percig, addig működik "nagy táp" (azaz 12V és 38V-gondolom a háttérnek).
Eddig a következő hibát találtam: a PWM LED driver OZ9909tn nem kap 12V-ot, (adatlapot nem találtam csak egy másik hasonló qfu2.1e_la chassis rajból láttam https://www.mikrocontroller.net/attachment/321427/philips_chassis_qfu2.1e_la.pdf 75 és 78 oldal, itt közvetlenül 12V-ot én esetembe legalább 1 valószínűleg kapcsolótranzisztoron keresztül, amit még nem sikerült lekövetnem.).
Egy hozzávaló rajz, vagy egyéb segítséget előre is köszönök makittib.
Kedves Kollégák!

Köszi, üdv, kovácsa
Üdv mindenkinek! Fentnevezett készülékben lakik egy 715GA428-C0A-003-004G Panel, ezen felrobbant a táp IC, aminek így sajnos a típusát sem látni. Valakinek sikerült már ezzel a hibával megjavítani a panelt (IC típus, beszerezhetőség, átépíthetőség)?
