hello all,
it's my first thred on this forum, but i read it for a long time.
i have troubleshooting with a samsung syncmaster 2493hm dysplay
it doesn't start, sources plugged or not, and there is no blue led !
fuses are ok, caps are looking good and values are ok on de smps with the multimeter (Farad test)
+5v wicom is ok
but +5v, power_en and +5v panel are not present
on the mainboard , i have 3.3V_live and 1.8v_live ok
r391 : no voltage
i found for ic304 something strange but values are ok :
-r388 : +5v on one side and only +0.07V on other side
-but the resistance value is 2.2kohm with multimeter
i found it very low for ic300 , don't you think ?
if someone can help me what i have to control now .
thank you a lot.
