SOURCE: Viewsonic VA1912WB error says analog signal

I had a Gateway 19" TFT that did the same thing.
Does the power light stay on? If so, you more than likely have "dry" solder joints at the inverters. Take it apart & shoot a little solder on the inverter solder joints. Good as new now. The solder joints dry out because of the high heat generated. This is a very common problem.

SOURCE: No display (black) - power light is amber color

The video signal is not reaching your monitor, check the pins on the connector from the monitor to the computer, then check the video card:

Turn off your computer, unplg the power, and then take out the video card. Wait 5 minutes and then put the card back into the computer and turn it on. For onboard video; turn off the computer, unplug the power, then hold down the power button on the front for 5-10 seconds, then plug back in and turn on.

Make sure the video card is snug in the AGP/PCI slot. If this is built-in video, try borrowing a video card from another computer and install it in this one. If the borrowed card works, then replace you card. If video is built in, then you can disble the onboard video and use the new card without having to replace your motherboard.

SOURCE: When it powers up the screen is fine then it goes

The lcd has three parts the screen plate(windows)/the logic(vga)/the inverter(power plug). Parts that go are the backlight ccfl's, behind the plate, and parts of the inverter, ie capacitors, all three take a bit of power from the inverter. The self test check that all the lights are ok and the inverter is ok, else it switchs off, ie if 3/4 light work it will switch off(my own case), hence the on chech error then off, However sometime there are stages of on/off ie on/ but no screen display, if that is the case the following may be of help...if you put bright light at an angle close to lcd can you see a windows shadow, text icons etc, ie still logic power passing,then .... (from a.n. other) after two weeks searching I finally find doctor living stone http://www.aplusperfect.com/articles/lcd_capacitor_repair more fun with paulbtorrent
the takening the case bit off is like opening your wallet a second time after buying a new LCD, but you must! smallest two screw driver's flat headed, practice using two pennies stuck together()with your fingers after, one little () move and inch and {} again, with the case , it does not break, just need to lever open
[once open you realize they somehow put that old briefcase clip inside!] also note the bright light test to do first to see if can see a windows screen , and that capacitors are one for a number of things that a make a inverter work! there a transistors as well, given that however, to replace all the capacitors on my inverter, was 11 capacitors, cost me $11 (uk ebay) and already had the iron and solder. So only cost me me $11 to try and see but no luck , still fun and I still can see the screen for 2 sec' at a time plus I have a spare set of caps now in the event that the new
one do go burst! you have to laugh really, what next , a new on/off
button, as you work though the whole inverter !
mmmMMMMmmmMMMMmmmMMMMTim Berners-leeMMMMMmmmmMMMMMmmmmcome back all is not
wellMMMMMMMMMMnnnnnnweek later land sight mmmmmMMMMMMMMMmmmmgggggggg(from
another a.n other)Generally, if the screen went out quickly, it was the inverter. If it went out over a slow period of time (flickering etc..) I would bet it is the lamp.replaceing the lamp should be pretty challenging. as that requires complete breakdown of your LCD, extraction of your dead lamp, and soldering in your new lamp... but I would like to say that I it did this after realizing it's 2 x kitchen strips inside [========] with wires that can connect back to the inverter with out any desoldering(ie kit assembly/dis) with the outter case remove (glass plate safe away) I could reconnect and see that 3/4 were working (i!i hardcard ) cause the inverter to switch off after a secound ! order bult and replace and going to cheap and see if I can get away with fitting a 15" in my 19' as it a 1/3 of the price ! the market as drop out there, hope the inverter does not miss the length, or the screen out put.

SOURCE: viewsonic vx2835wm monitor, in DVI

You are having a firmware issue or the main board is bad. Since you cannot get the monitor to work from either connector, and since this is a high resolution monitor, I doubt you are having any operating system issues. You can test the monitor on a laptop or another computer if you desire, however from the symptom it looks like the main board requires some attention. Contact Viewsonic at viewsonic.com or call their 800 number for service information. You could order a main board, but it may not have the ddc data programmed (similar to firmware) so you may have to bring it or send it to a shop for service. BTW, they have three year warranties. I would recommend calling Viewsonic.

Acer laptop display goes off after some second


Try booting into safe mode. Chances are that you have set the screen resolution and refresh rate to some value that the LCD cannot handle. That is why it works until Windows takes over. Once you are in Safe Mode you can get things under control.

Hello, I have a lg lcd monitor. w1941s model. when I start my computer, it work for sometime. then it goes blank showing only the LG logo. then the power button doesnot work. it hang up glowing. again


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

Vizio half of screen is solid color bars. Top half works great.


You have either the circuit board that drives that half of the screen(one for top and another for the bottom) or you have a bad display panel.

Outside display screen will not show anything but the motorolla logo


Does anything show on the external display if you go to take a picture, but before you acually take it, close the phone and look on the external display as if you were taking a self-portrait?
To make fully sure, while the phone is closed, press a volume button - does anything show on the display? If so, the external display functions and it would be a setting that may have been overlooked.
Go to Menu > Settings > Initial Setup > Display Timeout
or:
Menu > Settings > Personalise > Home Screen
