Monitor will not turn off

My motorhome has a vma 7194 monitor located on the back of the seat and cannot turn it off. The screen only displays vertical lines in various colors, especially green. How can I turn it off. I press the power button on the monitor and will not turn off. I am afraid if it stays on, it could heat enough to start a fire.

SOURCE: Blank screen or vertical colored lines on monitor

sounds like a graphics card failing

is it on board graphics ?

if so try a graphics card in there see if that helps it

also if you could borrow a monitor and see if that helps

SOURCE: VERTICAL COLORED LINES ON MONITOR

Your panels are dying.
Well more to the point the driver tabs that run the panel are dying and are not going to be cheap to repair for either case.

For the stand alone LCD, it is cheaper to get another one.
For the laptop, find a laptop on Ebay or similar with a dead motherboard and swap out the screens, also gives you spare parts for the laptop. If you goto a repair shop and get a screen it will cost you as much as a new laptop.

SOURCE: CRT Monitor Displays only a thin bright horizontal line

Vertical IC loose connection. Best is to reflux it or resolder. It is in internal circuitry inside the monitor commonly an upside single line IC.

And its a minor repair only. But I recommend it to be serviced by a qualified technician. Inside it are plenty of nasty voltages. It might caught you.

SOURCE: difficulty getting monitor to display when computer powers up

The Problem may be due to the defective inverter unit inside the monitor. Dry to resolder if any dry joint on the inverter PCB or replace the inverter board.

Have you tried to connect your laptop to external monitor?
If you get normal picture on external monitor, then you need to replace LCD screen, but if you get same picture on external screen, then unfortunately you will need new motherboard, because graphics card is integrated to motherboard.

Monitor display on Dell E176FP


You may loose connections at the end of the VGA cable, or video card not seated tightly. I would check that first.

Hi my hpdv6000 laptop is showing black screen,what to b done?


First we need to test if the problem should be the LCD screen. The easiest and most foolproof method for testing your lcd screen is to hook up the laptop to an external monitor. If the video output on the external monitor looks fine, this means that the problem is with the video connector, with your LCD panel itself, or with the circuitry that turns on the LCD.

Second we need to disassemble the laptop and find the video connector
on the system board (if the video is integrated on the motherboard) or on the video card that is attached to the motherboard. Try re-connecting the cables. You may as well locate the display connector on the back of the end LCD panel. Re-seat that one too. This way you can be sure that the problem is not related to connections.

Every now and then the switch located on the system board that turns the back light of the LCD on and off can become stuck. If this is the problem then your LCD never powers on. There's a little switch that detects whether the screen of your notebook is open or closed. That's the one we're talking about. Try to push it down and hope it gets unstuck.

Disassembling the laptop to unstick this switch is an option, but sometimes you can get away with not taking it apart. Try lightly hitting that plastic switch. But wait, this isn't the only possible cause, unfortunately. Re-seat the other connectors and cables that are present around the LCD panel and the video on board (including the inverter).

Sounds as if your monitor is not receiving a signal from your video card. In all likelihood, the video card came unseated during the move. Open the case and re-seat the video card, that should do the trick.

Write back if that does not solve the problem.

HI...

The easiest and most foolproof method for testing your LCD Screen is to hook up the laptop to an external monitor. If the video output on the external monitor looks fine, this means that the problem is with the video connector, with your LCD panel itself, or with the circuitry that turns on the LCD.
What do we do? It all starts with disassembling the notebook. Find the video connector on the system board (if the video is integrated on the motherboard) or on the video card that is attached to the motherboard. Try re-connecting the cables. You may as well locate the display connector on the back of the end LCD panel. Re-seat that one too. This way you can be sure that the problem is not related to connections.
image002.jpgEvery now and then the switch located on the system board that turns the backlight of the LCD on and off can become stuck. If this is the problem then your LCD never powers on. There's a little switch that detects whether the screen of your notebook is open or closed. That's the one we're talking about. Try to push it down and hope it gets unstuck.

All of the aforementioned can usually be fixed, but let's not forget about the screen itself. Sometimes the screen can become defective. Here we'll enumerate a few scenarios where the screen has gone bad and must be replaced: lots of vertical lines or bands appearing on the screen; half of the screen works fine but the other half stays either black (blank) or really white; the output on the screen looks blurred and changes to different patterns; and so forth. These are almost always signs of a defective LCD panel.
However, if the output on the screen is nothing but garbage, such as incorrectly placed special characters, shadows around the characters, unknown randomly placed marks of different colors, distorted or ugly-looking geometric patterns, or tiny little white dots all over the screen, then these are almost always due to the system board or the connection between the LCD panel and the video card. Re-seat the connectors.
All in all, these are some of the most common hardware failures. Nevertheless, before we finish this part, let's name some of the others that will be covered in the second segment of this guide, along with the promised system instability troubleshooting strategies. These include clicking noises coming from the HDD, which is the well-known symptom of a dying HDD. Thus, back up your important data as soon as possible and order a replacement. Overheating is also discussed thoroughly.

Good luck !!!

Monitor color display problem


Go to the control panel. Click on display. The display applet is your next stop. The display applet is your central location for all of your display settings, including resolution, refresh rate, driver info., and color depth. The display applet has 5 tabs: Thmes, Desktop, Screen Saver, Appearance, and Settings. The 5th tab is where you make adjustments that relate directly to your monitor and video card. Look at the Settings tab. At the bottom of the dialog box, you'll see 2 options. Screen Resolution and Color Quality. By moving the Screen Resolution slider, you can change the resolution. The most common resolutions are 640x480, 800x600, 1,024x768, and 1,280x1,024.Your system may have more or fewer resolution options.

The color quality is the number of colors displayed on the screen .You can change the screen resolution with a simple slider and adjust the color depth from 4-bit all the way up to 32-bit color.

Running a 32-bit color gives a nice, realistic tone to images, and many games insist on it.

Clicking the Advance button opens another dialog box with 4 or more tabs.

The monitor tab gives you details about the currently installed monitor and enables you to make changes to the driver and the refresh rate.

After you make your changes to your monitor and it still is not working properly, it must be your video card which is not seated.
In layman term, your video card is not plugged in firmly in the slot!!

Gateway FPD1960 19" CD has a red tint to all oc screen when I turn it on.


Make sure your VGA cable is seated properly. If it is seated OK, it could be the start of a problem with a backlight. When a backlight goes bad, it typically shows up as pink/red color where white should be displayed.

Monitor going black


My HP f1703 is almost 3 years old and started having this same problem. My fix got the display to stay on. Don't know how long this fix will work. I set the monitor brightness to 51 and contrast to 41. You may have to adjust to your levels to your appropriate enviroment. Levels may determine how long the monitor stay operational. Do NOT set your monitor brightness to factory levels it will just start to recreate the problem again. Solution: The monitor should be on with the blue button lighted. If the screen is acting up (you turn it on and the display lights up and then it turns off within 2 to 5 seconds) Try decreasing the brightness level down as much as possible. Wait 15 to 30 seconds and see if the display comes back to life. If not, turn the monitor off and on again and try the procedure again, if necessary. Cause: I believe the monitor brightness level, set at 100 by the factory setting, is over driving the display and causing the protection circuit to cut off the flouresent lamps that light the display. HP had an issue with this display, and had a notice to replace them if the problem occurred during the warranty period. They extended the warranty period from Jun 04 to Feb 06. Check with HP Technical Support to determine if your monitor is cover.
