Samsung hw-n450 Hangprojektor alkatrész beszerzés
Kedves fórumtársak!
Szeretném megkérdezni hogy a fent említett hangprojektorhoz hol tudnék beszerezni főpanelt.
A panel kódja:AH41-01883A
Esetleg van aki a Samsungtól tud rendelni panelt?

Előzmény:
A hangprojektor nem kapcsol be. Tápegység OK (24V) a szervizmanual (40-ik oldala) szerint kimértem a Micom ic 64-ik lábát és ott 3.3V megvan. Semelyik modul nem kap 5V-ot csak 3.3V-ot.

Köszönöm előre is a segítséget.
