My Toshiba P10 laptop screen no longer works. It appears to be slightly backlit but the display is blank. Connecting and switching to the external display works fine. Thought it might have been the inverter so have tried a replacement from ebay but no difference. Guess the replacement inverter could be faulty?

Re: Toshiba P10 laptop screen no longer works.
It's not the inverter but the biotin backlight bulb that lights the display from underneath. The screen needs to be replaced unless you want to try and rebuild it and replace the backlight bulb. New screens from EBay should not be more than 70-100 bucks. If you want to try and replace the backlight bulb, the link is below for the procedure.....

The problem is cause due to one of the following: the backlight or the display, check your monitor brightness settings. Sometimes your brightness may accidentally have been all the way turned down, resulting in a blank/dark screen. The monitor controls are on the keyboard, directly above the numeric keys. Look closely at your laptop's screen if the steps do not restore power to it and if it remains blank. Can you see a faint image on the screen? If so, the backlight may be off due to the LCD "lid close" detector malfunctioning. This malfunction likely happened due to the lid close switch being stuck in the "closed" position even though the lid is open. The switch is located beside the LCD's screen hinges, and tapping the switch a few times should unstick it. Use an S-Video cable and plug your laptop up to an external monitor, such as your television set. With the laptop and TV hooked up, turn both on and see if your computer's desktop is displayed on the TV. You can also use a fifteen ( 15 )pin monitor desktop monitor by connecting it to the blue fifteen ( 15 ) connector at the side of the laptop if you cannot see anything on screen it is the display problem. If it is, your laptop's display needs to be replaced. If not, your motherboard and/or video subsystem may need to be completely removed and replaced.
you must have accidentally touched some other parts, just open up the laptop again & look for some unusual things try connecting the wires again. it must be not a big problem. just some loose connections.
Try to right click on desktop, choose properties.
When Display Properties appear, click on the setting tab, you have to choose the related display to make the viewsonic work and allow it to run.
Firstly, the LCD+external setting will switch one or the other or both on.
Secondly, if you go into your display properties (or even the advanced page where your video card additional features are) you can usually select which monitor is "primary".
I suspect that your external display is primary, and the LCD screen is not "enabled" or used as part of the desktop.
The settings are all there, it's just a matter of finding them (depending on what video card is in whatever laptop you have)
This might have happened in the first place if you accidentally hit "Fn" and one of the "F" keys up the top. Fn + F6 on my laptop will switch LCD/external monitors on and off. (for example) There is usually a little blue picture on one of the "F" keys to denote that function.
Check to see if your Video Card is bad by plugging the laptop into an External Monitor... then press the F5 key to toggle it to the external source...If your PC shows up on the second screen, you have video issues...
