Question about Princeton Digital LCD17 17" Flat Panel LCD Monitor

1 Answer

White screen covers desktop

Monitor worked fine for several months. Moved to a new computer and worked for about 2 months then one morning upon reboot the primary screen is covered by a white screen. Powering the monitor off and then on, you can see the proper desktop for a split second before the screen goes white. I checked other monitors (LCD and CRT) on the system without problems. Moving the Princeton to another computer results in the same problem. I switched power cable to power converter and the video cable without sucess. Could the power converter failing cause this? How do I determine it is the power converter. It is supposed to be 12v @ 4.0A according to the box.

When I turn on my Vizio, the picture is "squished" and the bottom 1/3rd of the screen is white static. The TV is only 6 months old.


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

The monitor worked fine when we received it several months ago. Recently it started going all white, except for a few very thin colored vertical lines. I could shut it off wait a few seconds and torn it...


If this is still under warranty, then send it back for repair. If you have connected it to 2 PCs with the same results, then the problem is internal to the monitor.

LG LCD Monitor won't exit Power Saving Mode


Does your desktop/PC display show anything before the monitor goes into power save mode? If nothing comes up, its possible that you have a loose VGA connection or that your video card/motherboard are defective in some ways. Try using a different monitor.

If the other monitor works fine with your computer, try changing/lowering the screen resolution. If in XP right-click on the desktop and go to Properties, and select the tab for display settings and adjust the resolution. If in Vista/Win7, right-click the desktop and select Screen Resolution/Display Settings and adjust it there. Then check and see if your LG monitor works on it.

If the other monitor also doesn't show any display, most likely the problem is either with your video cable or your PCs video card/motherboard, not the monitor.

Hope that helps. Good luck

I have a Samsung SyncMaster 931c monitor (2.5 yrs old). Sporadically during the last month, I'd lose the screen image and get vertical stripes on the display. I'd turn the monitor power button off and on...


jcacolice, Most likely your 931c will need work done on it. When strange things start to occur with any LCD CCFL backlit display I would suspect the "switch-mode-power-supply" first thing!!! If unit is out of warranty you or someone will need to inspect and troubleshoot it. A good place to start will be to see some DIY videos on YOUTUBE. Try search of "lcd monitor disassembly" and "lcd monitor repair" and learn all you can about the TOP CAUSES of monitor failure. Then visit (FYI) www.ccl-la.com/badcaps.htm and www.badcaps.net for more info. Explore ALL your options before you do anything. Then get back to us here at fixya if you still need some asssistance. Read some of my other responses in my fixya profile and other those of other tech's on fixya.
Hope to see you back on fixya with a plan of action!! 12fixlouie

Blue tint...then unresponsive...only 5 months old


You're probably lucky that this happened now. You're most likely still covered under warranty. Contact Acer support and arrange a swap. If your pc works okay with another monitor there's no point in troubleshooting further. Get that monitor switched before the warranty runs out.

Lacie 19" Electron Blue - Black screen with a brilliant white line across


I have 2 of these monitors and have this problem. I was so frustrated turning the monitor off and on until the white line disappeared that one day, I punched the screen. And it worked! So now whenever this happens (about once every other day) I use my palm and smack the lower left corner of the monitor until the white line disappears. I like the color on these screens so I don't want to replace them until I have to. I will NOT buy another Lacie though.
