First, I would use a multimeter to verify that the power adapter is good. It should have an output of 14VDC. If it is working, the next step in verifing that it is a backlight problem would be to connect the display as normal and, with it powered up, shine a bright light on the screen at an acute angle to see if the desktop image is being displayed. If you can see the image, then it is probably the lamps or the inverter.

To remove the cover, remove the four screws attaching the base and after the base is removed the 2 halves of the cover simply snap together. Using a jewelers screwdriver, start at one corner and gently pry the front bezel away from the back, working your way around it. There are 4 locking tabs on each side and 5 on the top and bottom.

This display has 4 lamps, 2 each at the top and bottom of the display. This is the easiest display I have seen as far lamp replacement goes. At this point, all you have to do is disconnect the lamps wire from the inverter, remove the tiny screw, right below the point where the wires connect to the lamps, and carefully slide out the lamp assembly. Be very careful not to flex them while removing.

Check the lamps for burnt spots at the ends or physical damage. If the lamps look good then I would not rule out the inverter as the problem. At this point, if you are not familiar with electronics, I would seek help from someone who is.

I hope this helps.

The monitor screen went black but the power light stays on. Have turned it off and then back on. The screen comes on for about 1.5 seconds then goes black again, almost like it's timing out.


haynie1, If you shine a bright flashlight 1 inch from the black screen and can still see the Win-desktop screen, you will need to have have unit it fixed or trade it in for new wide screen. The fluorescent lamps on rear of lcd panel need high voltage to light them!!! If the CCFL inverter circuit has failed you will have a "black screen" problem. Do some reading in my fixya profile for a while, then you will understand problem. Follow the links to see if you will learn to do a DIY repair or not. Your unit's lamps may have too many HOURS on them and need to be replaced also. Good luck. 12fixlouie

Monitor does power up but no picture??


heck342, Your monitor may have the common "black screen of death" that will occur to ANY AND ALL cold cathode-fluorescent-lamp, back-lit, lcd monitors sometime during their lifetime. You will need to do a lot of reading in my fixya profile and those of "buddymc" , "budmrtn" and then you will understand what you will or will not do with your unit. I'll even bet you haven't been to YOUTUBE to view any DIY repair videos yet! Come back here for more info after you do a little research on the WEB, and can tell us tech's that you know the difference between a "black screen" and a "blank n black screen" monitor. Remember this, your CCFL back-lit lcd unit" design and principle of operation isn't any different than any other brand. Have you done the "flashlight test" that every CCFL back-lit lcd monitor owner should know how to perform and interpret the resulting info when black screen of death occurs? Bye for now. 12fixlouie

Viewsonic vp171s lcd flickers on start up then goes black.


This is typical of a back-light problem, especially when you view the LCD screen at a sharp angle and you see a dim Windows image. This fault is caused by either a faulty inverter board or a faulty CCFL lamp.
The inverter supplies high voltage to the CCFL lamp. the CCFL lamp is a mini fluro lamp which fails with age and use.
This LCD screen can be repaired, the cost of an inverter board and CCFL lamp is a lot cheaper than a new LCD screen, but this is an opportunity/excuse to buy a larger size LCD screen as these monitors have dropped in price.

My monitor on my Dell laptop went completely black while I was on it. I have tried turning it off and back on, and the monitor is not working at all


You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out; usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

LCD Monitor needs repair


I used to repair LCD monitor from Dell. It works for me. You might be using these following steps to examine what is the problem of your LCD monitor. After you turned PC on and monitor stopped working or went black, 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 look very closely. If you can see the icons or any image (Start menu), there will be a minor problem. This is because of CCFL lamps inside screen. Some of them were broken and it is very easy to replace. You don't need to do anything with the inverter board in this case. If you cannot see anything on the screen, there'll be some problems with inverter board. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

Flickeing like a dying fluorescent light bulb


Actually this is a 'warning' signal from your lcd monitor. The problem is your lcd ccfl lamp are near to their life, need to change. The ccfl lamp like our home fluorescent lamp, when the lamp need to dead, the lamp will flickering first, after some time, will totally off(dead). So, this is a signal for you. Some lcd monitor, when their inverter board are using fairchild inverter ic(oz series), will easily shutdown your monitor when they detected some flickering on your screen (ccfl lamp).
