Having problems with your ViewSonic VX922 19" Monitor Flat Panel ?

LCD Screen blinks on & Off at start up up-to about 10 minutes

\015 I have a Gericom 19'' flat panel LCD monitor. When I first start the computer the screen and led light keeps blinking, also picture comes on and off. I did try it on other computer same result. After about 10 minute I get the picture on the screen. Also sometime after 2 or 3 reboots everything is normal until I shut off the computer. May be after about an hour if i try to restart the computer same problem however it takes less time perhaps 2 or 3 minutes for the screen to be normal.\015\012I have read a lot of post mentioning Capacitors, looking at PCU I can not seen any blown capacitor. I did notice some brown stuff on a round coil like (about 1cm round copper wired, says 125\302\260 on it) object. \015\012There are about 20 odd capacitors on PCU, i have no idea which ones needs replacing.\015\012\015\012I would be grateful for any help?\015\012\015\012HPI have a similar problem but only when I connect my Viewsonic VX910 LCD display to my new computer running Vista Ultimate 64 bit. When I connect it to my old XP machine, it works fine. Right now, the only way to stop the blinking is if I1. Wait it out, OR2. Reboot, OR3. Click on my account once Vista boots up (which is hard to do since the monitor is blinking).What's the problem? My new graphics card is a 1GB ATI Radeon HD 4850\015

Okay, forgive me if I go over covered ground but reading the post, I only see your responses, not what was recommended. From everything I've seen the problem lies in one of the following areas.

  1. The video cord is damaged. A bad cord will occasionally work since some current does flow to the machine but not enough to work all the time Check for any bent pins on the cord. If there are any bent pins, a new cord should solve your problem.
  2. \015\012
  3. If the graphics driver has recently been updated, it's possible that the monitor can't handle the accelerated graphics. Most graphics drivers updates are tweaks that increase the performance of the graphics card. Although your computer and graphics card may be able to handle the enhancements, it's very possible your monitor can't. If this is the case, try restoring your old graphics drivers..
  4. \015\012
  5. The video/graphics card is loose or poorly seated. This would explain why sometimes the montior works fine and other times it won't work at all. If you have onboard graphics built into the motherboard, this would not apply
  6. \015\012
  7. Lastly, if none of the other solutions work: Since you are experiencing the same result on different computers, the problem lies with your monitor. A bad monitor will occasionally work until one day it quits altogether
\015\012I do hope this covers all the possibilities and answers your monitor question. Again I apologize for going over any covered ground but somehow someone latched onto your post and I had to filter out your problem from the other person's. Best of luck.

I have a 3 yr Dell UltraSharp 1905FP LCD monitor. Recently, when I turn it on, the power on green light would blink continuously for about 1 minute with no picture before the light become steady green and have picture (everything working).
