    More information:

    The closer the laptop power converter is to the screen the worse the problem.

    It appears perhaps the cabling or the screen is not insulated from outside non contact electrical interference.

    I still very much have the problem and being technical, I can help your technical department isolate and troubleshoot the issue for a fix.

One may try attaching RF filters to the video cable. These are usually formed-powdered iron rings or molded flat pieces that enclose over the cable, one on each end near the cable connectors. A plastic cable strap will hold these pieces in place. Or one could search for a video cable with the filters built-in by the manufacturer. Another "Technical" individual.

Just bought HDMI to DVI cable to connect my VL193 to my HP laptop - unable to get the monitor to "pick up" the signal - just a blank screen - if I power it on & off, just goes right to power...

Hi

Desktop PCs automatically seek an external monitor to output graphics to. Laptops default settings send the image to the internal monitor. You need to manually instruct the laptop to export the image to an external monitor.

With the cable connected and the monitor powered up, try pressing the Fn key (bottom left of keyboard) on the laptop and simultaneously pressing the function key at the top ofthe keyboard with an image of 2 monitors (often F5 or F6) to sent d the image to the external screen.

I hope this helps.

I have rolling lines on my monitor. It is an Acer Al1916w flat screen monitor. It began last night when I pressed the reset key by mistake

Hello, There could be two possibilities. Drivers for Video card are not installed, bad. or a faulty monitor (could be loose inside the computer) or graphics card. Another reason is because the cord that goes to the computer for whatever reason is to close to a power cord or power bar. Have you tried moving it any?
After eliminating all of these things the only thing left is the monitor itself and within the monitor the only component typically capable of producing rolling lines as you describe is the power supply.
I suspect it's the refresh rate in the monitors settings. Try making the refresh rate lower.

A fine blue line has appeared down the side of the screen any ideas

To determine if you have a provlem with the LCD screen or the video card, connect an external monitor to the laptop's video port and power up the monitor first and then the laptop. The video will divert automatically to the external monitor. If you get a normal Windows image on the monitor then the fault is with the LCD screen, if not then the fault is a faulty video card.
Get back to me with the results of this test.

IBM Laptop A31 2652 Garbled video even at initial boot screen

Connect an external monitor to the laptop, power up the monitor first and then bootup the laptop. The Windows image will automatically divert to the external monitor.
If the images is OK then the video card is OK.
From the description of the fault, it indicates that the fault could be a faulty video cable or video connector. Try reseating the video cable/connector on the motherboard.
Get back to me if you still have problems together with any error messages etc.

Kds model 780 monitor no signal, power button does not work

My monitor does the same thing at times and sometimes shows "No Signal" and at other times the screen will maintain the images but the backgound color switches to mustard yellow. In each of these cases I have been able to solve the problem by unplugging the power cord from the electical outlet for about three seconds and plugging it back in. I have a KDS model 780 LCD.
GOOD LUCK

Monitor problem

Hi,

Appreciate the "Ask Me".

I am assuming that you have more than just familiarity with electronic components and circuitry, the use of a DVM and a soldering iron. Further, that you have access to a service manual.

Width problem is basically insufficient horizontal deflection, then analysis would have to be in the horizontal section. Areas to initially focus on:
  1. 12V line and pin 29 of IC401;
  2. 110 V peak to peak at collector of Q403, if yes check Q 402 & 404 as well as T401;
  3. other components that affect the horizontal size are:
  • IC201
  • Q 405, 406, 407 & 408;
  • D409
  • L401
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Lines on the Screen

2 possibilities video card is damaged and bleeding ac power from the motherboard or the motherboard is damaged from a power spike and is bleeding ac power into the video card(this would be my best guess based on yur description). that is the best i can do on this info you have given I recommend you take it in to a service center for a definitive answer.

Rolling display image

You will need to take your monitor in for repair or buy a new one. I could get into the specifics about WHAT exactly causes this type of failure but bottom line is the same.
