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...Last edited by rqbwins; 04-06-2012, 01:49 PM.

Re: Could use some help, trying to fix HP 1940 LCD
On the back of the panel I have 2 diodes of the same kind.Can someone tell me what kind of diodes are ?
I changed the tranzistors and ewerything else but I am having the same problem.
One of the diodes from the back seems to be blown.

2:IRFU9024NPBF TRANZISTOR MOSFET,P I-PAK -55V-11A
3:IRFU9024N IR HEXFET(R) POWER MOSFET 55V/11A38W -ROHS-
