No picture on monitor when hooking up for the first time

It could be a couple of things. If this monitor is hooked up to a computer, it could be a bad video card. A video card is easily fixed on a desktop, if you're using a laptop you're probably out of luck.

If it's hooked up to a DVD player, check that the cord to the monitor is hooked up properly (make sure the connection goes from the "Video Out" on the player to the "Video In" on the monitor and that all connections are tight, not barely hanging on). If that doesn't work, try a new cable.
This is probably insulting, but also make sure that the monitor is set to the right channel if it's multichannel. For example, if your DVD player is hooked up to HDMI 2, make sure the monitor is set to use HDMI 2 for signal.

If none of these work, it's time to find a tech-happy friend that can inspect everything visually. Hope that helps!

right click on the background of your destop and select properties. go to the settings tab and change the screen resolution till the picture is normal size. there is a box to select to make my default monitor which will move your windows bar from the computer monitor to the tv.

Try a 2nd monitor on the cpu and see if the same thing happens. If the same thing happens then the video card is bad on the computer. If you hook up the 2nd monitor and everything is working then you know the original monitor is bad.

To me with the picture showing and then going out like that, that tells me there is a problem with the lcd itself but to replace that would be more then the cost of a new LCD.

Not sure what the problem is, but I would suggest pressing the Fn+F5? There is a function key that toggles from dual screen, just the laptop screen or just the monitor. Hope that helps..

on your laptop keyboard, press function button & monitor button at the same time .

Try connecting a mouse and keyboard to the laptop and then start it with the top closed. Not sure if this will work on your model, but it works on a lot of laptops. This should force the PC to use your external monitor as the primary one.

Your video card (or driver) is probably to blame.
Try hooking a new monitor up to the computer to test this.
If so, try the advanced settings in control panel. Many cards give you the ability to manually alter the picture.

If that doesn't fix it, replace the card.

i need help getting my astar flat screen tv to power on. the blue light is on in the center of the tv

Hi,

 

My name is Todd and I'm with Dell's online outreach group.  Have you tried hooking that monitor up to another system to see whether it's the monitor itself or the system causing the problem? 

 

Is the color distortion always there, or is it only happening at certain times or with certain applications or programs?

Let me know if you're able to try this monitor on another system, or another monitor with this system.  If not, we can try a few different things to test it.

 

Thank you,

 

Todd

Have you tried giving it a good tap on the side? Hey its worked before. Have you tried hooking it to another machine to verify "yellow." Was it yellow on your friends computer? How old is the monitor? Good Luck, Tim
