42PC1RV LG V8 nincs kép
Sziasztok! 42PC1RV LG v8 plazmába y-sus hibrid lett cserélve és átkondizva. A tápok rendben vannak. Sajnos nincs raszter továbbra sem. A kijelző felületén változó helyen apró zöld pöttyök villannak fel, ami egy korosabb kijelző esetében normális jelenség, de se menü se szemcse nincs. Merre kapirgáljak?

Áramszünet után csak az LG logóig jut el ki-be kapcsolható.
Lehet vele kezdeni valamit, vagy alaplap csere?

LG 32LV2510-TA - backlight not ON
LG 32" LED - model 32LV2510. The TV shows power but baclight is not ON. I checked 24V from the power supply and its there. I chechecked the Inverter/ON voltage and its there 3.3V. I took a torch and tried to illuminate the screen - I could see the OSD, if I press the menu - it comes up etc. I don't think the backlight is faulty. Between the power supply and the main board - I am missing something. Please help.
LG 32LF5800 készenléti led gyorsan villog, készülék nem reagál semmire. (megoldva)
Sziasztok!
Lényeg a címben. Tápegység (most már)  stabilan működik, készenléti feszültség rendben. Ennek ellenére a led, megszokottnál jóval gyorsabban villog és nem is reagál a tévé semmire. 
Vélhetően nem áll fel a készenléti állapot(sem).
Valakinek tapasztalata esetleg ilyen jelenség kapcsán?
Köszönettel: Kiss Zoltán.
