On laptops both the laptop LCD screen and the external video port can be toggled to show laptop LCD, external vodeo and bothe laptop LCD and external video.
You need to press and hold down the Fn key and one of the function keys that has the monitor symbol, repeated pressing this function key will toggle the video outputs.
I cannot advise you which function key works with your laptop as they vary between different laptop manufacturers.

My monitor screen is black. The green light is on but black screen


The green light usually indicates that the monitor is getting a signal.
The lack of a picture is an indication that the monitor itself is having a problem. I would test the signal with another monitor if you can get one.
I suspect that the monitor backlight has gone bad (if so, you can see the screen very faintly if you shine a light on it).
Or, the screen circuitry has gone bad.

My Sansui LCD TV scren is black but there is still sound and when u change channels, you hear it changed the channel but no picture! its all black


The backlights inverter board or the power supply section for the backlights inverter board may have gone out, you need to take it apart and troubleshoot it with proper tools.

Soyo DYLM1988 Comp Monitor; monitor powers on with picture for only 3 seconds, then picture goes blank (black screen), the power light stays on.


If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Samsung hdtv to compaq pc


There should be a setting within the comp. Is it connected to the comp monitor and the tv? Perhaps from the comp to the tv with the monitor from the comp as well? Well if so, you may need a certain setting within the comp. Check under (on xp) display properties, and then under the settings tab. Please rate!

You can get another power supply at any of the computer retail stores for $40-$50. Pls take you comp's power source to the store as they come in different sizes and not all fit your comp.
