any hope to have benq V773 schematic diagram ?

have download acer v772 schematic, similar but components different.
problem that i have:- NO DISPALY
but EHT working, flyback trans working. and 45V to B+ step-up working, beam working.

not sure the G1 voltage -180V is normal ? and the RGB cat. voltage is aroung +60V, so the cat. to G1 voltis : 60-180=-120V , will this couse brightness shutdown ? or ABL shutdown ? any ideal ?
