Re: Could use some help, trying to fix HP 1940 LCD

My simptoms are 2 second to black screen.On the attached photo ewerything in white circle is changed, and resoldered all the 16 pins.I am afraid to test eweryting becouse the diode on the back of the panel in the right corner is showing me 0.00 on both readings with my tester.The other diode in the middle is showing 0.143 on one reading.
On the diode I can read S4 590 or 59A I am not sure

Have you checked if your lamps are working right?

It will be S4 59A but i think it must be obsolete. Other members seem to use the one I mentioned earlier SS24 SMB 40V 2A instead.
Diode should have a low resistance reading one way and high resistance the other. If it is low ohms both ways or high ohms both ways it is faulty.
