SOURCE: Data Shows up only on External Monitor, not on Laptop Screen

Hi,

Since the laptop works on the external monitor, then it would be safe to assume that it is only the L:CD display part that is the issue. Often LCD display (of laptops) are working but only that you can see the actual display. One way to verify is to shine a flashlight at an oblique angle to the screen, semblance or part of the desktop could be seen. If the desktop could be seen (albeit very very dark background) then it could either be the CCF Lamps (cold cathode florescent) or the inverter that powers the lamps.

Often, the defective component would be the inverter. It is relatively easy to replace the inverted. It is sometimes more difficult and challenging cracking open the casing of the display panel of the laptop than replacing the inverter. Additionally, inverters are readily available online. It is also not surprising that inverters for other brands/models would also be used in your Toshiba.

This would be a good place to start for inverter boards. This is a nice tutorial if you are considering a DIY.

In some worst case scenario, it could be the video interface or even a loose/open flat cable from the laptop's main body towards the LCD display panel.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

The power inverter needs to be replaced. it involves removing the LCD opening the LCD bezel and swapping parts. Power inverters and much cheaper then LCD screens. You can take the LCD apart and find the part number on the power inverter or just search for one for your model laptop.

SOURCE: black screen of HP notebook, but external monitor work

i 100% agree with you. i found out that my notebook is one of the recall product from HP. I sent it in for service. A week after the repair, the same problem is back again. So I call HP and they said that I have water damage on the board. I am 100% sure the notebook is no where need any liquid at all time. So they tell me if I want, they can fix it for me for $375. I would highly recommend everyone not to buy HP products!!!!!!!!!!!!!!!!!! I always have problem with HP products and I think they have the worst customer service of all. Once again, do not buy HP products!!!!

I would back mothmans answer 100% but might suggest you re-assemble the display to the laptop if you continue to have problems getting an external display going.

Can you see what's on the screen if you hold it under a light? Did the screen die suddenly or were there more symptoms?

Cq56-115dx boots to black screen


Your thinking along the right lines, first of all check the laptop using an external monitor, if you get the same problems on an external monitor it is likely to be mainboard/GPU fault. If display is fine on an external monitor I would recommend taking the laptop apart and check the LCD cable is connected correctly as the first port of call. If that doesn't cure your issues I would look at replacing the LCD cable, then maybe the screen.

Either your LCD Video Cable is not plugged in snuggly or the monitor is slowly going bad. The fact that you can see the images on an external monitors says your Video Graphics Card is working fine. You'll need to disassemble the laptop to get to the cables. Get a quote from your local computer shops, then try the guys at: http://www.generalsystemsconsulting.com Most times they will fix it and ship it back by Fedex or UPS cheaper than any quote you obtained including the shipping.

Replaced cracked display screen with new one and screen is black. System works with external monitor. Is there any drivers that need installed?


1. Test using an external monitor. If it works, then either the screen bulb or the inverter board might be defective.
2. Test the inverter. Easiest way to do it if you have a good screen with a good bulb. Connect the good screen to the inverter board & test it. If it lights up, then the inverter board is good. If it did not, then the inverter board is bad & needs to be replaced.
3. If the inverter board is good, then we are left with the possibility that the screen bulb is bad. To fix this, we will need to replace the LCD screen.

Compaq Presairo V2310US no display on the screen, external monitor works


If the external monitor works than that is good news in a way because that means your video chip is good. Take a good close look at the screen, try to see if the desktop is actually there but just very dim. If you can make out a shadow or any part of the desktop then maybe just the video inverter has failed. Even if the inverter did fail, some lcds are so black that the desktop can't be seen regardless. In a case like this I would recommend not only getting a new screen but also the inverter as well, or replace the inverter first, it is only 15-20 dollars. Then, if the screen still doesn't come up, then change out the screen. Also make sure the data cable that attaches the motherboard to the back of the lcd is firmly seated in the socket, this can also cause a dark screen.
