PDP42V6 fara imagine

Recommended Posts

La un LG RZ-42PX11 cu PDP42V6 fara imagine am verificat urmatoarele.Tensiunile din sursa,5V,Va,Vs si restul sunt OK.Sigurantele nu sunt arse.Pe placa de semnal (placa TV propriu zis) sunt cateva leduri ce semnalizeaza tensiunile -sunt OKPe placa de control e un led ce clipeste unul aprins si trei stinse (din manual asa reiese ca e bine)Intrebarea ce o am unde se masoara Vsetup,-Vy si Vscw?Cumva pe rezistentele la care scrie pe placa? (nu am scos inca placa Y-sus) si nu-mi dau seama asa unde ar fi.EditIntre timp am vrut sa masor (tot dupa manual) dioda dintre Y-sus si GND si am gasit scurt din cauza placii Y-drive (cea de jos)Pe ea doar condesatori SMD si integrate siliconate.Fara aceasta placa a aparut imaginea.
