Hi everyone,

I have a problem with my Toshiba Satellite Pro 6000. It has stopped showing any image. It worked fine when I connected it to an external monitor. I'm at a loss as to where the problem lies. Can anyone tell me procedures on how I can test it. I checked the connections and all seems fine.

Any help is highly appreciated.

Following 's description (internal screen died while an external monitor still showed output) and 's suggestion to check display settings, the next steps should focus on quick, low-risk diagnostics that distinguish a software/config issue from a hardware failure and narrow which hardware part failed.

Steps to isolate the fault:

  1. Flashlight test (no disassembly): power the laptop with the room dark and shine a bright flashlight at the LCD. A very faint image means the panel is receiving video but the backlight (or inverter) has failed. No image at all points more toward the panel, LVDS cable, or video circuitry.
  2. Display-toggle key: use the function key with a monitor icon (the model-specific toggle cycles internal/external). This confirms the internal display channel can be selected.
  3. Power drain and RAM check: remove AC and battery, hold the power button ~15–30s, then boot. With power off, reseat memory modules; bad RAM occasionally causes no-screen symptoms.
  4. Angle/flex test: with power on, slowly open/close or flex the screen. Flicker or intermittent image during movement usually indicates a damaged/loose LVDS ribbon at the hinge.
  5. Inspect connectors/inverter only when powered off: remove the bezel to check the LCD connector at the panel and on the motherboard. In older laptops the inverter or its fuse can fail; inverter testing or replacement is relatively inexpensive compared with a full LCD or motherboard repair.

Safety and practical notes: always remove battery and AC before opening the case and use ESD precautions. The inverter and its wiring can carry high voltage when powered—do not probe it live unless experienced. For a 2000s-era Satellite Pro, try inexpensive parts (inverter or cable) first; panel or motherboard/video-IC repairs are costlier and may exceed the machine’s value. When contacting a repair shop, list the model and which of the tests above produced faint image, flicker, or no image at all—those details greatly narrow the likely fault.

Could be that your laptop configured itself to display on external monitor only. That happened to me while back.
What you want to do is plug the monitor in (plug&play, baby) and right-click on your desktop (empty space), select properties, then click on settings tab. There you'll see an illustration of two displays. One will be greyed out. That's the laptop display. Under that image you will see somthing like "primary display..." or "secondary display..." or "(name of the monitor) on (name of the VGA)click on it and change to the other one.

Post the results, please.

No. It's not configured to run only on an external monitor. I was using it when the screen went dead.

Maybe it went dead (the LCD display).
You should have it repaird.
There is nothing you can do about it, unless you're licenced electronitian.

Sorry.
