Question about ViewSonic VP171s 17" LCD Monitor

Open Question

Strange colours on VP171s monitor, plus flickering

We have replaced two fuses in our monitor in the last two months.

Today, when we turned on the PC, our screen saver (which was a largely grey picture), is now displaying in lurid pinks, purples and blues, and the screen is flickering. On Windows programmes, our screen bars (title, scroll, etc)have become bright lime green (and the title bar has vertical lines of other colours, some flickering running across it), and when we go on the web, some images and text are unreadable as the backgrounds colours are flickering and too dark, and other images are flickering.

Is it dead?

SOURCE: A line of Dead Pixels.

You are right it is a stuck or dead pixel, usually if it is a colred line but not grey it is a stuck pixel at the beginning of the line you can try a utility designed to flash bright colors repetedly over time to see if this will "unstick" it. Also you could have a dry joint on your TCP which would require opening it up to diagnose.

Viewsonic vp171s lcd flickers on start up then goes black.

This is typical of a back-light problem, especially when you view the LCD screen at a sharp angle and you see a dim Windows image. This fault is caused by either a faulty inverter board or a faulty CCFL lamp.
The inverter supplies high voltage to the CCFL lamp. the CCFL lamp is a mini fluro lamp which fails with age and use.
This LCD screen can be repaired, the cost of an inverter board and CCFL lamp is a lot cheaper than a new LCD screen, but this is an opportunity/excuse to buy a larger size LCD screen as these monitors have dropped in price.

My monitor doesn't display anything, though it's receiving input from the CPU. I know that input is being received because the monitor status light is green, and times out (turns orange).

Same thing happened to me! Went to bed last night, everything was fine. Woke up today, orange light came on, no display, slight flickering seen, but that's it. Cables and cords are fine, tried unplugging and plugging it back in, NOTHING. Totally dead. I'm guess off to buy a new one today. Typical made-in-China JUNK.

Monitor won't start when I boot up - without a lot of fiddling!

First try to do monitor self test.Disconnected the blue cable VGA or white colour connector from monitor to the computer. Turn on the monitor and check if you are able to see colours or line on the monitor.Indicating self test monitor is working fine. If you are using Video card on computer connect monitor directly to onboard video and check. Good Luck.

Sounds like you have a video card problem. If it works on someone elses PC and not yours. Replacing this video card on your PC should fix it..

Monitor problem

If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. May need to check the caps in the G-2 supply circuit. Also you may have a CRT going flakey. Just a slight G2 level adjustment may suffice also. Good luck
