Agreed with above, new monitor is needed. Is it covered by the dell warranty?

Seams Monitor problem for sure, no cables problem. Its covered by dell warranty ?
If not the explaining is simple, the power supply can hold the lcd power consumption for this reasons:

1 - Lcd high voltage lamp's (two) are damaged and the power supply enter in protection.

2 - The power supply have a malfunction, normally  its' a electronic capacitor of
10uf/22uf/47uf in the primary voltage transformer side that needs replacing.

3 - Also this two last problems can coexist in the same monitor.
 
To solve this you need some electronic skills, and the second reason it's cheap and the more common to happens. If not, forget the monitor buy a new one.

Since you've tried both multiple cables and multiple PCs, it's fairly clear the monitor is broken.    As already noted, it's not economical to repair it.

"... older 19" flatscreen dell monitor .."

"... older ..." ==>  almost certainly out of warranty

"... 19" flatscreen ..." ==> relatively small ... and relatively inexpensive.   19" displays are readily available for ~ $100 (a bit more if you need standard aspect ratio instead of widescreen) ... and even the high-end ones aren't much more than that.

it can be the backlights stop lighting
it can be the inverter, or backlights
if you feel like repairing it yourself (i did so) look for bad capacitors, leaking or bulging; mostly in the PS, but i had 2 bad ceramic caps on the HV side also
