Re: HP 1940 - no backlighting
I connected the two pairs of CCFL. The effect is the same. The backlight lights up for a moment only a first line (shown in photo). The second line there is no backlight....

HP 1940 - no backlighting
Hello,
have LCD HP 1940. Got out in it's backlight.
Power board: BenQ 48.L1G02.A01
Replaced Q808, Q809 on C5707, Q805 on FU9024N and PF801 125V/5A fuse (I had no counterpart here so when I put the glass fuse 250V/4A).
When the monitor, there is a backlight for about 2 seconds and stops working again.
What do you propose to make this work?
When replacing the fuse busted my pad of PCB. So I did this (IMG_20130719_164600.jpg ). I think it has no effect on the backlight.... -
