Question about ViewSonic VA721 17" LCD Monitor

1 Answer

IBM LCD computer monitor is dim

I bought a used 15" IBM LCD monitor that is not very bright even when the controls are turn up to the max. I'm pretty handy with electronic repair. Is this a somewhat inexpensive repair like changing some bulbs? (not an expensive screen as the picture and colors are fine)

Your backlight may be going bad, or the small controller board may be going bad also. You will have to contact ViewSonic for prices. It is not that difficult to change them out.

Dim display problem


Hi there,

Have you tried adjusting the LCD's bright and contrast using the buttons on the monitor. Instructions can be found on page 12 of this manual:

https://computinghardware.web.cern.ch/ComputingHardware/doc/Samsung/SyncMaster740B/SyncMaster740B-940T-E.pdf

If the lcd monitor is dim even upon booting up, then the backlights of the lcd itself is starting to fail and it needs to be replaced.

Please let me know if you need further assistance. Thank you for using FixYa. Merry Christmas!

Lcd is very dim. after changing res a glow in the lower right corner starts then back to darkness. It works fine with my vga monitor.


Hi, display DIM cause by LCD or inverter Board (brightness controller). Might costly. Up to you either want to change it or not.
And using external monitor is best solution, I think so. =)

MY ACER MONITOR IS DIM , HOW DO I BRIGHTEN IT UP?


Push the button on the front that says menu. Within that menu you will find the brightness control. Use the other buttons to move through the different menu items until you get to Brightness. Once there push the menu button again and then adjust the brightness with the other buttons.

Iiyama Prolite 434S monitor is too dark


Dim or dark display can be caused by a faulty inverter board or faulty CCFL lamp. The inverter supplies high voltage to the CCFL lamp, the CCFL lamp is a miniture fluro tube and these dim with age.

Monitor dims on a black background hanns G 28


Go into monitor settings and turn "off" X-Contrast. X-Contrast will auto change contrast when backgrounds darkens. However, adjust manually the Brightness and Contrast settings to compensate.

Monitor too dark....


Usually every laptop has the option of adjusting the screen brightness as you would want the screen to be pretty dim when running on battery to conserve battery life.
First thing to check would be just that.

Too bright


I just bought an Acer 19 inch this morning and I am assuming you have the same controls on the bottom of monitor. On mine I push the menu button twice....the left arrow once to select the brightness slider.....push the menu button again to turn slider red and active...then use your left or right arrows to adjust brightness...afterwards you use the menu to get you back to the exit button and that's it....I hope Don

Have lost ability to control brightness.


lost,
wow a CRT that even glows at all , and you wonder why its dem
the electron gun cathodes get weaker every day of its life.
all CRTs do that, not one or even TVs using CRT
the red gun always goes dim first so we crank it up in the OSD.

if it fails on all PCs, the monitor is bad, a 5 min test. and bingo
then if the monitor is known bad then what.
the OSD screen ever seen that, and the front panel key marked MENU/?
go there and play with brightness, and even the electron gun tuning, the page for that is RGB, Red Green blue.
adjust them so white looks OK.
but if all are dim, that is normal for old CRT,
we only get like 3 folks a year stuck in 1990s... or older.
the labor to fix it is 3 times a new LCD LED display.

land fill time. like the other billion made, and scrapped
