There are 2 possibilties. Either the LCD power inverter is bad, or the LCD backlight. The inverter is not too hard to change and they are inexpensive. The backlight is inside the screen itself and you would need to replace the whole screen. Put the laptop in a dark room or area and turn it on. If you can see a very faint image on the screen it is probably the inverter. If so post back here to get replacement part locations and replacement instructions.

Hook a spare monitor to the video output on the back of the laptop, if okay it means the video card is working fine. The problem is a bad inverter board, "located under the LCD display" or the back light is defective behind the screen, "usually means a screen replacement"

If you shine a bright light at the faulty screen and you can see movement, the back light has failed otherwise the LCD/LED screen has failed. Purchase a new part through flea bay and follow the video prompts on utube showing you how to replace the screen.

How to check if you laptop screen has gone out


turn on the laptop, if fan is running and the lights that normally work are working.
shine a bright light on the screen if you see a low lit display the screen is fine.
Its either your Backlight or screen inverter which provides the power to the screen.

Screen black and drive not running. No lights except ON which didn't turn off. Removed bat...went off. Replaced bat and only Power light came on.


Have you checked the Function Key combinations that switch your display to an external monitor, from the laptop's monitor?

Screen doesn't light up


Brand new? please take it back to your dealer. I assume you do have it plugged to the charger and it has power? it doesn't matter if the battery is empty or not, the laptop works with the charger with or without and battery.

seems like you got a faulty laptop.

PROBLEM WITH MY SATELLITE M35X-S111


Check to see if your Display is bad or Video is bad..
To Do This....
Plug an External Monitor into the laptop serial port..Boot the laptop and use the function key plus F5 to boot to external screen... If you see your PC running on the external screen it is a Video card/chip problem.....

Do your lights run ..the Power Light/Battery light/ hard drive light??? Do you hear the hard drive spinning??

Laptop crashes shortly after boot, power light rapidly blinks red.


Its late, so just to make sure I'm not brain-dead basically your laptop runs fine as long as its powered by the AC adaptor but dies fairly quickly while running via battery. This is very typical of a battery that will no longer hold a charge, not normally a user repairable item. It could also be that the charging electronics (in the laptop) isn't charging the battery, again not a typical user repair job. About your only option short of taking it to the repair shop is buying or borrowing a battery as a test.
