It sounds like the cable between the motherboard and the LCD. My advice is to take it to a repair shop.

Toshiba m60-104 screen dark new screen new iverter


Have you tried an external monitor?

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If the display shows on the external monitor that proves your video card is ok and your lcd screen is the issue. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If is shows on the external monitor, then you would have to question if the new screen and lcd inverter is bad. Just because they are new don't mean they work. Are you sure you purchased the lcd screen and inverter that is for your model?

Dark screen


Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

When connected to ac adaptor it will turn on and toshiba leading innovation appear, but after that no program will displayed, but when i disconnected to the ac adaptor the programs runs normally. the


This is strange.
I think your ac adapter power cord is bad. Get another one from ebay at: http://www.ebay.com

Just put in your computer's make and model, not the model of the battery in the ebay search.

For example: Toshiba Satellite Pro L300 AC Adapter

It might be your lcd screen's inverter, but it's strange. Anyway test the inverter by plugging in the ac adapter and when the screen goes blank try the steps below.

My hp compaq model 510 is not working with projector.projector is not working on this laptop plz provide a proper solution.


You are not providing enough information to help you.
Have you set the display to use an external monitor or dual monitor? That is how laptops work with projectors. You normally can set the system for dual display and either mirror the displays or use the second display (projector) for power point or other presentation.

If this does not fix the problem, post more information on why it is not working for you.

The display has dimmed, and looks washed out (faded)


You most likely have a defective CCFL backlight, it may have the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
