Question about Dell UltraSharp 1504FP Monitor

Dell UltraSharp 1504FP Monitor - Blank Screen

Hi, My monitor screen has completely gone blank. I can see it is receiving power as the switch button is still glowing and i connected another monitor to my pc to find it prefectly working. So there's a problem with the monitor. I think it might be the fuse. How can i solve this problem I have seen a similar question posted on this forum before but no satisfactory answer was given. The so called experts were rambling about warranties!

Monitor going blank after 5 minutes of use (Was working for longer periods of time, but now down to about 5 minutes). I have tried turning the monitor power off then on, the screen comes up for a few seconds and then goes blank again.

Same problem occurs when plugging it to a different computer.

Noticed the Mfg date is November 2003... Is it time for a new monitor or is there still hope for this one?

Thanks,Michelle

Screen has gone blank but the power light is still working. I did find that if i held it to a light just right i can see an image and even read whats on it, it's just not lit-up.

Well friend if the fuse is the problem, you will not see any power light indicator. probably theres a problem in power supply circuits or most probably the horizontal deflection circuits. which includes the horizontal oscillator, horizontal drive, horizontal output and maybe the flyback itself. but if you dont know anything about this, better bring it to a qualified tv technician. good luck!

The capacitors are leaky in the power supply(usually bulging). Change the 3 in the heatsink area(little caged area in the corner(You'll see them). And the four small ones over by the transformers and you will be right as rain I think. Fixed mine.

Powers up, screen visible for about 3 seconds then goes blank.

There are two versions of the power supply/inverter PCB assembly, you need to look inside to see if it has any bad caps with bulging tops first, then post back so we can guide you further.

I can not find the correct drivers to configure my dell ultrasharp 1504fp. Only showing low resolution 4 bit and does not allow any other monitors other than default.

Are you sure that your problem is with the monitor drivers? Usually when graphics card drivers are correctly installed, the monitor is recognized as "Plug and Play monitor" and this is completely sufficient, as the monitor is able to communicate it's supported resolutions and refresh frequencies to the video card.
Look for an updated graphics driver for your system - first you have to establish what type of graphics card you have, then find drivers for it.

Dell 24'' Ultrasharp went blank

I suspect the invertor supplying power to the Xenon backlight tubes has failed.
This can be reapired but may not be cost effective.
Ask for a quote from your local computer specialist but keep in mind the cost of a new monitor.

Blank screen

Hi,
Disconnect the monitor , from the computer, switch the monitor on , if you have some kind of Dell self test box running on the screen. The monitor is OK . The problem can be with the video card or resolution settings.

Also, try connectin the old monitor you had hooked up with the system to check ,if you see anything

Thanks
