Problema lampa proiector nec


Recommended Posts

Ma chinui sa pornesc lampa la un proiector nec , model vechi, voi reveni si cu modelul exact .

Proiectorul porneste , incearca sa porneasca lampa si intra in eroare , eraorea apare pe ledul de status si nu cel de lampa .

 

am demontat lampa si se vede descarcarea pe electrozi dar nu porneste  . nu vad starea exacta a  electrozilor  dar lampa nu pare  fisurata  sau inegrita .

 

Ce pare ciudat e ca  in timp ce incearca sa porneasca lampa  ventilatoarele "mornaie"  parca scade tensiunea pe ele . Am masurat tensiunea DC ce pleaca din sursa principala in sursa lampii si nu variaza deloc . 400v .

 

Inca nu l-am facut bucatele  m-am gandit sa cer o parere inainte
