Question about Gateway FPD2275W LCD Monitor
The monitor powers on but no logo just ablack screen. When I shut off computer the signal turns the green poer light to amber. But I dont know what could cause my screen to not show anything. Make : BenQ Model: Q7T3 Product number FP73I
I wonder if this has a backlight in it. Most/or all LCD flatpanel displays use a backlight in them, namely a small florescent tube (a tiny version of the office florescent lights). If this is burn't out, or the little power supply which runs it dead, you will have a black display. The image is actually there, you just can't see it, except perhaps faintly when external light hits it just right. The display must be disassembled to check this light. If you have tech savvy, and some equipment, voltmeter, maybe an oscilloscope, you could check it out. Where to get a replacement lamp? Google it... perhaps the manufacturer.

If the 2SC5707 transistors have failed short, there's a 3A fuse PF751 that will probably also be blown.

Check your computer's power supply. A power supply that is shot will cause the symptoms you have.
