No monitor display

Just hooked up Dell 1707FP monitor in place of original monitor that came with my HP Compaq 7500 system. The Dell monitor has several input choices but I used the VGA source since that's all my PC offers.

I got a brief flash of what should be displayed and then screen went black.
Tried self-test. I got the test pattern for about one second then screen went black.

Re-hooked up to original monitor and all worked as usual.

Any suggestions why Dell monitor cannot display the VGA signal. ?

  1. Unless it has an input menu that you have to specify what input you are using it looks like you got a bad monitor.
  2. sounds like the flouroscent tube used for the backlight in the display needs to be replaced.

    Is that a big - costly - repair job?
