Question about HP f1905 19" Flat Panel LCD Monitor
The screen is white when turned on. I have swicthed the LCD screen with another and the other screen worked find.
Look for surface mounted fuse on the T-CON board, it is where the connector is attached to. Check to see if the fuse is blown if it is, set the meter to Ohm mode and check the resistance on the output side of the fuse (the other side of the fuse lead should be connected to the connector. 5vdc is fed to this fuse, if you read real low resistance then you have short circuits, then there is not much you can do.
When you do not have voltage to bias the liquid crystal, the crystal will be aligned and let all the backlight to come through the panel, so you will see white glowing screen.
