This 17" Dell monitor, model number CN-0M1609-4633-3AG-2DTL, will power on
when AC is first applied. In the middle of the screen appears, "Dell Genesis
Display Perfection." Then it disappears after a second. When you press the
power button with no input signal, the Dell self test feature check
illuminates in the bottom left corner of the display. You can see the red,
green, blue, and white bars within the self test box. Then, it starts to
scroll diagonally up to the right for about a second and then the display
turns off. The power light remains on. If you hook it up to a PC, you do not
get any display. The boards are in good condition and I reflowed the solder
over many of the components with no improvement. Any ideas what might be
going on here?

Thanks for your reply.

Did you check the power supply voltage(s)? Low power supply voltage and high
ripple/noise can create a myriad of symptoms.

Why did you reflow solder? Were there bad joints or intermittents?
