It does this with another PC also?
Most common failures are due to bad caps.
Please read below first:
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 ACER monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Screen making quick flashes


This could be a LCD screen problem or a video card problem.
Connect an external monitor to your laptop, power up the monitor first then boot up your laptop. The video will automatically switch to the external monitor, then go to the Internet and see if this flicker occurs on the external monitor.
If it still flickers then the video card has a problem.
If it does not flicker the the LCD screen maybe faulty.
Get back to me with the results of these test and I can advise the nexr course of action.

What's your problem?On going problems with Samsung R519 laptop after all the advise I tested laptop on separate monitor and it worked fine with no problems I bought new screen lead and still had p


The external monitor has proven there is no problem with the video graphics card, I'am concerned that customers have complained about faulty screens.
I have changed a lot of displays without issue, there is a major circuit board mounted behind the screen that plays a roll in picture production so if something goes wrong you get all kinds of symptoms from fuzzy images to multi color lines to a blank screen. I would suggest getting your money back because of his track record, also go online to Samsung and contact customer support and the technical department to see if something was over looked. Question! is this a new or used LCD display?

My monitor compaq model MV520 is always blinking every time I open my computer, How can I fix it?.


Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to answer and solve your problem. Your Compaq MV520 Monitor is always blinking every time you turn on your computer and you want to know how you can fix it? First, we need to troubleshoot the problem. I'm thinking you probably need to refresh the flicker rate on your monitor. The flicker rate is probably set on a low setting, which is causing you screen to blink (flicker). This can be bad for your health as well because it can cause eyestrain and headaches. Your monitor is a CRT (Cathode-Ray Tube) model. These types of monitors can cause a lot of screen flickering. Now that we've troubleshooted the problem, now it's time to solve the problem. There are two ways you can solve this problem. You can either refresh the flicker rate or you can buy an LCD monitor. LCD monitors flicker-free. My suggestion is that you refresh the screen flicker rate. To refresh the flicker rate, go into your System Preferences or Control Panel, click your operating system's appearance and display link and click your screen adjustment link. You may have to click your advanced settings link. Click your monitor tab and from there adjust you screen refresh rate. You may have to adjust your screen resolution before you refresh the screen rate. If you have to do this, make sure the screen resolution you choose supports you monitor's height and width as well as visibility. The higher the resolution, the higher the screen rate. The instructions I'm giving you may sound like this because I'm not sure what your operating system is. I'm not to familiar with Mac Operating Systems, but if you have a Windows Operating System and you need better detailed instructions, just reply back. I hope this decreases your screen flickering and gives you a better viewing experience.

Connect the monitor to a different computer (laptop or desktop), to see if the problem "follows" the monitor.

Connect a different monitor to your computer, to see if the video-card in your computer is generating the "wavy" display.

Move any "power-bars" and PC Speakers *FAR* away from the monitor, to eliminate electrical interference.
