Re: Monitor is Flickering and screen becomes pink
Hi this is the way how to examine what's wrong with your LCD
monitors. Power on both CPU
and monitor. After it goes back to white, you have to
check that if you can see the image on the screen or not by shining a
flashlight into the
screen, not directly but find the best angle to the screen and take a
closely. If you can see the icons or any image, there will be a minor
problem. I used to check my LCD monitor and could see window image
using flashlight and found out that Some
of CCFL lamps inside were broken and it is very easy to replace. If you
cannot see anything on
the screen, there'll be some problems with inverter board. If you have
soldering tool and want to fix it by yourself, check the caps first. It
cause this problem. Some caps might show leaking or burn spot on the
because of too high temp. If you don't have soldering tool, you better
go get a
technician to do so. Thank you, Tan

The flickering is most likely the florescent backlight having a hard time starting, Just like in a light fixture, as it gets old, it takes longer to warm up to get full functionality.
If under warranty, contact Dell for a replacement, if not, then when it becomes untenable, replace the monitor. Prices are dropping drastically, an new 20 or 22 In can be bought for about $150 or less
Thanks for the git back: #1 I hooked up a second monitor (depressed fn+f5) and was able to view everything fine. No problem in any area. Ran Some security checks (malwarebytes,checked windows updates,Secunia PSI,and a virus scan. #2 I opened up the monitor and checked for possible loose connections. #3 brought up the graphics display and checked that 60 hrz was set and correct. #4 ran a backup of all my data from my other monitor,and I made the assumption that it was a bad monitor and I might save some money if I just bought a new laptop.Would like to here your comments. Sincerely : dandee4u3
To determine if you have a video card problem or the LCD screen is at fault.
Connect an external monitor to the video port on the laptop and boot up your laptop, if you get a display on the external monitor then your video card is OK and you have a faulty LCD.
When you power your laptop without an external monitor and have a close look at the LCD screen at and you see a slight image then the fault is with the backlighting panel. This fault could be a faulty inverter or a faulty CCFL backlight lamp.
Defective CCFL backlight may has the following symptom:
Screen flashs on red/pink and off.
Picture stays on in red and slowly be come normal.
Picture flickering with dim display.
Picture flickering on and off.
The inverter can be easily replaced so can the CCFL lamp (but requires a lot more work)

check the monitor refresh rate setting.right click on the back ground on the main windows screen. Choose proprieties from the menu that opens, then click on the settings tab on the top of property window. Next click 0on the monitor tab and increase the refresh rate at the bottom of monitor window. That should do it.
Check to make sure the cables are connected tightly. Wiggle the cable, does it get better or worse? Might need a new cable. And reseat the video card inside the computer. If that doesn't fix it, then yes you will probably need a new monitor.
My Acer AL1711 packed up last week, I bought a new Acer and noticed they have a 3 year warranty. Give Acer a call on 0870 853 1000, and they`ll do a warranty repair with free pick up and return - great service! Not sure if you need proof of purchase or not, luckily I had mine.
