ViewSonic VA550 problem with horizontal blurryness

I was given a VA550 for free. Cool huh, until I started having problems about 2 months ago. When I first hooked it up I had no problems, but recently, after the computer is turned off for any amount of time, the screen is distorted with horizontal fuzzy lines. When I use the buttons on the front of the monitor, the screen that pops up has no fuzzyness at all, but any info running to the screen from the tower has the fuzzy problem. After it warms up for a time, most of the lines clear up. I tried changing the refresh rate from 65 to 70, and that helps occasionally, but today it had no affect. After leaving the monitor and computer on for about 4 hours, it looks perfect. Any ideas?

    "resetting the settings from the menu..." Resetting the refresh rate? The resolution? Which menu? Your answer is somewhat ambiguous... It doesnt have anything to do with the sharpness or brightness because it works well with the setting options on the monitor itself, just not with any info sent from the cpu.

    Yes, I have the same problem...fuzzy horizontal lines. The monitor, itself on screen adjustment display does not show these fuzzy horizontal lines. Only information coming from the PC shows these lines. Of course, I tried a different PC and a different VGA cable. The problem appears to be in the video circuit of the VA55O. I also substituted the external power pack. I still have the same symptoms. I am hoping someone might be able to tell us it is some bad electrolytic cap on the circuit board. Thanks in advance for any suggestions.

Try resetting the settings from the menu ....

Hi there, My Viewsonic failed about a year ago and I'm hoping to bring it back to life Problem: It won't turn on. Observations (thus far): Green light visible on AC Adapter, as well as on Logic Board Caps...


Buy a new monitor!! Seriously, unless you're the techie type that likes to tear open electronic equipment to see how it works and/or fix it, you're better off buying a new monitor especially if this old monitor of your's is a LCD.

ViewSonic 19" flat screen monitor goes black - intermittently


Hi,
There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,
Graemevm

Was having problems with my vx922 lcd display.


Sounds like my problem that I fixed by sending back for repair.
I read that these VX922 monitors are affected by dodgy capacitors on the power board.
I had the monitor for over 2 years. Viewsonic picked it up, yep u guessed it... changed 2 caps on the powerboard sent it back all within 2 days, under warranty. I got my awesome monitor back. Its all good!

Viewsonic warranty


Hi,

I've had several problems with Viewsonic screens, and not only with screens but also with their technical support which would litteraly take monthes to proceed with the replacement of faulty screens.

Two things you should know :

You can find spare power supply cards, it's easy to open the screen and take out the power card so that you can see the reference, usually a card like that costs about 10$, not a big deal for saving the screen

The other thing is that you shouldn't buy Viewsonic screens anymore, there are brands from asia like Hyundai (for workstations) or Samsung for personal use, who have a way better technical support, the best part being that you usually never have to call them :)
