My monitor switched to a blue tinted display with low resolution and I am unable to change it in the properties menu?


Look to see if cables are ok in the back. You may have a faulty cable or faulty processing board in the monitor. Shut off monitor and computer. Turn on monitor first, then computer. Is screen still blueish? If so and cable are good your monitor is bad. It is very unlikely that it is your computer are when they fail they just stop working. Good Luck

Our PJ862 we use for church has developed a blueish tint to the display. It is pretty harsh and looks really dark and blue. Any solutions? Would changing the bulb help?


Since this is a 3LCD type system, I believe the blue organic filter polarizer glass plate that filters the blue light beam before it enters the blue LCD panel is burnt due to old age and causing the picture to go blue.
You can confirm this if you safey remove the cover and check the optics.

I have a ViewSonic VA703B, I need to get it working but I cannot get the back of. How can I get the back of.?


gregmclure1, Most rear covers kind of snap-apart from the front plastic bezel. need to remove pedestal first. Best thing to do ,go visit YOUTUBE view typical "LCD monitor disassembly" and or "LCD monitor repair" videos FYI. PROTECT THE LCD PANEL AT ALL TIMES!! You may even find a video of someone working on a VIEWSONIC monitor. Hope this helps. If it does, then rate this on fixya.

ps What will you be working on once the back is removed? Do you know what to look for?

Monitor is blueish


If the Blueish problem appears try play around with the VGA cord and see if the Colors comes back, if not, try hiting the monitor to see if the lines and color problem comes bcak to normal. If not your monitor's circuit board needs some dry solder, it could be the cold solder problem. Cheers.

Blue tint on computer display monitor


Try
1. Unplugging the video cord from the back of the computer (and screen if it comes off) and plugging it back in. Sometimes it can become loose and cause a screen to have a abnormal color contrast
2. Updating the drivers to your card
3. Trying a different monitor on the computer. Mind you, if you plug in a differant monitor and the color stays the same. Check the videocards pins on the back of the card. I dont know if you gave all the info on how it became like this, so maybe it got undone and plugged back in forcably and one of them got bent? I
Also if the pigment goes away. Plug the normal one back in and if its gone, great!, if its back. Try the OSD settings on that monitor. Still no luck. The monitor is junk.

Hope that helps
