    stuart_38, If you haven't been to YOUTUBE to view some of the longer and more useful video clips of "lcd monitor disassembly" and "lcd monitor repair" , then go there first!!! Remember this!! 98 percent of all lcd desktop monitors use the same basic "lighting technology" to "backlight" the lcd panel. Do your research and then come back here to FIXYA and let us tech's know what you have learned and if you can do the required repair/refurbishment of your unit. If age of unit (4-6years) is problem, you should retire (trade-in) for new wide screen???? Also do some reading in my and "buddymc" and "budmrtn" fixya profiles for more info and links that you will find there. Keep us informed as to what, if anything, you will do. Bye for now. 12fixlouie

I'm a Master Mechanic with a degree in Automotive Technology and OEM training from Ford, Chevy, Daimler Chrysler, and several other OE and Aftermarket Manufacturers as well as being ASE Certified.
I find it amusing that "it's 4-6 years old, retire for new..." is an acceptiable "FixYa Solution" to a technical REPAIR question.
While it might be good to recommend a newer technology when a given repair is expensive and or challenging, you shouldn't imply that RETIRE IT is a FIX.
If you claim to help people actually FIX things you should provide a complete and accurate procedure for TESTING (as Bud Martin recommended) and PHYSICALLY FIXING the cause of the failure which brought the customer to ask the question.
I came to learn the procedure for testing and repairing the backlight system on a LCD monitor. I learned that I should go to youtube cause FixYa cant help me FIX anything, and the "SOLUTION" is to retire it... I WANT TO FIX IT, AND I WILL.

P.S. Sorry this is not a "Solution". Or is it?

Are you sure it is the lamps not the backlight/power supply problem?

If you are really good at soldering delicate components and very steady hands, you may be able to do it.

Viewsonic vp2000s LCD computer monitor - no image displayed; possible backlight outage.


It is possible that the backlight has quit working. Use a flashlight, held at an angle to the display, to see if there is a faint image visible. If so, then have backlight repaired. Otherwise, try a different input / cable.

It is possible that you can adjust your refresh rate. You may need another monitor to set the rate.

You may also be able to boot into safe mode. Try pressing F8 as soon as the system completes the POST (if you can see it). From safe mode, you can adjust the rate.

Can you get anything from the monitor without connecting to a computer? You should try to reset the monitor to its default settings.

N2700w how to replaced backlight or were can i find the replacement backlight part ??


You are unlikely to get help from Viewsonic, from my experience and from the 1000's of complaining former customers. Best source is finding the same model with a working backlight and some other problem, including a broken screen, as long as the backlight stays lite! Find out if it is the light or the inverter or a power supply issue first. Then out of 2 bad sets, make 1 working one.
