You need to look for bad solder joints, bad caps, shorted transistors, etc,
See example here:

If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

You might need to change the screen refresh rate. Go do Control Panel> Display> Setting> Advance, choose 60 Hz.

If your Dell monitor still under into warranty, better to call Dell technical support and have them replace your monitor coz there is no way you can fix on it.

If the monitor is beyond with the warranty already, better to but a new one than taking it repair that will cost you much.

Thank you.

Laptop LCD goes black after a few seconds


Yes, The pink tint is an indication that the backlight is failing. Now the backlight is basically dead, the best way to get back going is to do an Ebay search for your model laptop and get a new screen. Most screens can be purchased for around $50.00 - $70.00 and they are very easy to swap. Email me if you need more info.

Dell E171FP Monitor goes black after 2 secs

Hi, I don't think the problem is with your monitor. Your monitor sounds like it's doing exactly what it's supposed to do. The monitor is supposed to turn off if there's no cable attached, which means there's no signal input. When the screen goes black, does the power light stay on and turn orange? or does it go off as well? I would recommend that you lower your screen resolution to 1280x1024 or lower in the Display Properties window, then remove your primary monitor, and connect the monitor to your desktop computer. You should see it light up when connected. The monitor auto-senses when there's a computer attached to the cable and when there's a signal. If it doesn't see a signal, it goes black to save power.

I have A "Dell" E152FPc, and I have found an open transistor (Q201) on the Power Supply Board. My monitor comes on nice and bright for approximately 2 seconds, then goes dark; the power LED is steady. The voltage to the PWM IC is waky.
Before you try any hardware troubleshooting go to your control panel and turn off any power management options.
