Yes...same result.. i don't think it's a driver issue since powering this monitor without the CPU should display this Self-Test Feature Check (STFC) but this one simply keeps turning on and off.. |

check inverter ng CCFL .... ...marahil kabaak lng ang gumagana ... auto shutdown yan pag nkadetect ng problema sa my CCFL ... kalimitam gumagamit yan ng mosfet... at transistor.... ...pullout mo ung pyesa then check gmit multitester mo... kakaayos ko lng nung skin .. ganun rin ang sira... mas maalwan gwin ang lcd kesa sa tube type..mahirap lng hanapin pyesa ng lcd .... check mo rin fusible ... sa linya ng supply papunta sa CCFL inverter... kung fu9024 ang mosfet... pde jan ang d10pf... ang transistor nman ay c5707... marami nyan sa raon kaso kelangan kaw mismo bibili... para macheck mo... naranasan ko mgpabili... bago ung pyesa pero my leak... buti na check ko....

sa experience ko pag inverter ang problema, standby ang monitor. naka orange yung led, hindi ito nagrerestart. check mo din yung inverter board.
