SOURCE: my screen on my satellite has gone completely

Hi,

This could be a problem with the LCD inverter, GPU (graphics processing unit), memory or it could even be related to the battery.

First of all turn the laptop off and remove the battery. Then turn the laptop on just using the AC power only see if that resolves the issue.

If not then remove the system memory which you should find in a compartment underneath the laptop (you will need a philips screwdriver for that) clean the brass contacts and the slots that the memory clips into and then put the memory back in and try to boot the laptop up.

If that does not work get an external monitor and connect it to the laptop. Use the keyboard toggle to switch screens, its usually Fn and one of the F keys (between F4 and F7 usually)

If the monitor comes on and shows the boot information then you are looking at a new inverter or re-solder the old one.
If the external screen doesn't come on then the problem could be faulty memory or a down GPU.


If you need anymore help on this matter please post back.


Good luck and regards.

Toshiba Portege r200 was working normal (up until yesterday). Today, when I first turned it on, the fan was on and it sounded full blast, but screen remained dark (blank). I held power button until it shut...


The part that supplies the power to the screen is gone. I recall is is called the 'exciter'. They can be replaced, so take it to a computer repair shop. Same thing happened to my Toshiba.

Have signal, but no light, just one second screen can see and shut off.


Please clarify by shut off you mean power light turn off or just screen gone blank but power light remain on!

Mostly inverter(power supply) needs attention in such cases.

This sounds like the lcd monitor cable has gone bad, or the inverter or lcd screen have gone out.

Blank screen when turned on, hdd runs , cd runs but no screen output


Hi

This sounds like the backlight has gone or possibly the invertor. May be best taking to a reputable repair centre where they will probably charge you around £140 to resolve as they will probably change the screen.

One other thought is that sometimes the switch or sensor for the 'closed lid' may be sticking. Locate the little switch that shuts the notebook down when the lid is closed and just ensure it isnt stuck down.

Monitor is blank when we turn the computer on.


Maybe not. Find the FN key. It is usually BLUE in color
Then look on TOP row of Computer keyb (or all over) and find CRT/LCD.
Press the FN and that key and your screen should come back. You accidentally sw. it to CRT (outside, external monitor)

Self-Test Feature Check (STFC) Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
  1. Turn off both your computer and the monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
  3. Turn on the monitor. The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
  4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Thanks
