Screen lights up, but no display dell precision m6300, display with external monitor


Hi,

Looks like the LCD screen has gone bad as you are getting the display on the external Monitor.
Try This to run a test to check if it would still work or not:

1. Turn off the Laptop
2. Press and Hold the D key on the laptop and then press the ower button to turn it on..
3. Leave the D key when it starts

This would run the check on the Laptop and if you see the color bars then the LCD is fine, if not then you would need to get it replaced.

Check this article for more info about this test:

Hp 6715b vga's to external display fine, but no internal display. Replaced display cable, inverter, and lcd is good, I know this as fact ! Still no display, HELP ?


Hi, First push your FN- and the F- button that has the display symbol it may be set to the external screen. Can you see anything on the screen if you hold a flashlight close to it? If so I would say your back light went out and will need to be replaced. If this is not the case, recheck your cable and make sure it is grounded properly.
Also check the sleep button, This should be located above the keyboard. Sometimes it gets stuck.

My emachines D620 is turn on but not displayin on screen


Hi Mark,

From the scant details provided, the best solution I can offer is that the back light has burned out. To verify this, turn on the monitor. Shine a bright flashlight at the screen. If you can see stuff on the screen, e.g. Desktop, boot sequence, anything else. That would confirm a problem with the back light. What most LCD monitors do is have a light behind them or along each side that make the screen shine. What normally happens is after a long time the tube burns out. if the system is only a couple of years old, then most likely the inverter that steps up the battery voltage to higher voltage to run the tube has failed. In either case, IF you can see a display with a flashlight, then you will most likely have to replace the display. You can buy a completely built one from emachines (now a gateway company) or if you have the skills, replace it yourself. I found on ebay new displays for under $100

Sadly the other thing that happens fairly often now is that the graphics chip overheats and becomes "unsoldered" in which case you will have no display when shining a flashlight at the display. You can also confirm this by trying an external monitor. If you have another monitor for a desktop or if a friend does, you can plug in the monitor and see if you get a display. You may have to tell the laptop to use the external monitor by pressing the Fn key and the display function key. The display function key will have a picture of a monitor on it. Or you can look up the correct key sequence in the user manual which can be downloaded from emachines. The external monitor will also help confirm that the built in display is the cause of the problem if you can get a display on the external monitor.

If you need more help, let me know the results of the flashlight and external monitor tests and what further help you would like.'

Thanks, Jim

BLACK SCREEN ON MY ACER 5532


Hi,

Welcome to Fixya. I would like to know when you turn the laptop on is it running? Can you see the light that indicates that it is on?

We need to check if this is caused by a LCD or motherboard issue. If you can connect an external monitor on your computer and tap FN + F5. This will toggle the display. If you will be able to see the display on the external monitor it means that the problem is the LCD but if not then the problem is the video graphic that is embedded to the motherboard and to be able to fix it is to replace the motherboard itself.

Please let me know if you have questions. Thanks for using Fixya.

Hi ive got a dell studio laptop the laptop powers up but nothing comes on the screen. The screen is less than 12 months old


HI there.
Try this things first so that you can check if it is really the screen that's causing the problem,
While the computer is off, press D+POWER button and hold it for 5 secs, different colors should come up,
Make sure the computer turns on. You will know that if the power button lights up. Try to lug in an external monitor and see if display will come up,
If the display comes up, and the d+power did not display anything, might want to call technical support so you can get the screen replaced,
Have a good day!

This is simple on the dash board in your cluster area, there is a rest button, like to one you use to rest trip mileage. Turn you ignition on to the for position, that without the light in the cluster are on eg the abs light and stuff like that. Push down on the reset button for 10 seconds. Still holding the rest button turn the ignition on to the 3rd position this where the abs lights and other come on in the cluster area. Hold for another 10 seconds. Then release the light should go out when vehicle is started. Good Luck
