Dell LCD monitor flashes white every second, and then goes black

Hi, My dell LCD 17" monitor flashes white every second, and then goes black. The green LED also flashes orange. The only way I was able to make it temporairily stop was by giving it a good smack on the back of the monitor. Initially, it would only occur when the computer went into sleep mode, and then trying to come back, this would occur. As time passed, the flahing got worse to the point where every five minutes this would occur. I broke down and got a new one (the warrenty expired about 2 months before), but I would like to fix the monitor if at all possible without having to spend a lot of money. However, I do not know where to begin. I have it apart, but cant find any obvious problems. Hope someone can help!! Thanks in advance. Mike

    My Dell E173FP 17" LCD monitor looks great when it starts up. After less than 5 minutes, parts of the screen begin to flash white. Then, within the next 10 minutes the flashing areas expand and flash more frequently, so that eventually the entire screen is white and no longer shows any other color. If I turn the screen off for a couple minutes, it looks great when I turn it on again. But then warms up quickly and begin flashing again. Thinking that some component is overheating, I removed the plastic casing and tried dust-spraying the various components inside, to see if I could cool anything and see if it made any difference in the performance of the screen. No luck. YET. I am concerned about removing the circuit board from the screen part, as it seems there may be some sort of anti-static strips between them, and I don't know how important they are for the short term.

    Has anyone been able to resolve a problem like this?

Take a very good look at the power supply capacitors. Are any of the tops of the electrolytic capacitors domed? If you replace them, use a high frequency high temprature replacement to prevent a repeat failure. Don't use a standard 85 degree cap. It won't last.



Buy a new one PLEASE, HD monitor works best but the least expensive ones are smaller

I have an Dell Inspiron 15 and the monitor is flashing black and white with white or black stripes and sometimes goes completely black. What is the problem and how can I fix this? ANNOYING!!!!!

Hi Diane,
My name is Rohan and I work for Dell.
1. If you are using an external monitor for the laptop and it is flashing black and white, please try a different monitor.
    ·If it still does that then you will have to contact Dell tech support to get the motherboard replaced with the graphic card
    ·If it doesn't, then it is the Monitor you are using
    2. If you are talking about the LCD on the laptop, then use an external monitor and see if you still get the issue.
      ·If it does, then it the graphic card again
      ·If it doesn't, then it is the LCD.
      Either ways you still have to contact us on 1800-624-9896 (United States) to get it resolved.

Dell 1704 monitor goes to black screen after one

Hi my name is Rain.
Ok so that im clear on the problem. your monitor will come on but in a matter of seconds it goes to a black screen?
If this is the problem. The answers you seek will most likely
be in your video card.
Try this test:
  • Unplug monitor from the computer.
  • Turn on monitor .
  • Look for monitor self test screen.
If you see the monitors self test screen then your problem indeed is
the video card . You will need to replace the video card inside of the computer.

Dell E173FPc 17" TFT when turned on goes black

Hi Gaz,

First, verify the monitor is functional.
Monitor STFC (Self Test Feature Check)
Turn off the monitor
Plug the monitor power cord directly into the wall socket to remove any surge protectors or APCs from the troubleshooting equation
Unplug the monitor video cable from the back of the computer
Turn on the monitor
The floating dialog box should appear on screen against a black background.
If the issue appears during the STFC, the monitor is defective. What are the results please?

Dell 17inch LCD Display - Blank

Hi, My name is Todd and I'm a customer advocate at Dell's corporate headquarters. My team helps customers via blogs, forums, and other tech sites online. You said the monitor is 2 years old. Do you have the original order number still? Depending on how you purchased the monitor it may have up to a 3 year manufacturer warranty and I may be able to replace it if it is within that warranty period. Please email me at [email protected] if you can locate the order number and I'll be glad to see if its still under the manufacturer warranty. Include my first name (Todd) in the subject line of the email so it can quickly be routed through to me, and include the order or customer number if you have it. Thank you, Todd Customer Advocate Dell, Inc.
