I have a Toshiba Laptop that is about 5 years old (Tecra A8). The other day when I turned on the laptop I saw the screen flicker, but it was fine after that.5-10 days after this incedent (I was able to use my laptop during this period) I turned on my laptop and the screen goes black. I could still hear the computer booting up and could faintly see the images on the screen. I have read other forums and tried pulling the batt and power cord and holding the power switch, and that has not worked.

It should be noted that the screen does fully come on for a brief few seconds and then will go blank coming out of standby or when you first turn it on. Any suggestions Please

Brief expert summary and a focussed diagnostic path that expands on the replies from and .

The pattern described — visible faint image while the laptop boots, a momentary normal backlight, then the screen going dark — points to an illumination or panel-connection issue rather than an OS problem. The quickest way to narrow the cause is a short sequence of non-destructive tests, followed by safe inspection steps if those tests point to the display assembly.

  1. External monitor: connect a VGA/HDMI monitor and boot. If the external shows POST/desktop, the GPU is fine and the fault is inside the lid/panel or its wiring. If the external is also blank, suspect the GPU or motherboard. Use the laptop’s display-toggle key (look for a monitor icon) to switch outputs while powered.

  2. Flashlight test: with the laptop running and screen dark, shine a bright light across the LCD at an angle. If the desktop image is visible faintly, video signal is present but the backlight/driver/inverter isn’t lighting.

  3. Hinge/wiggle check: open the lid to different angles and gently move the screen while powered (watch for sparks or obvious damage). If brightness changes or the image appears only at certain angles, the LVDS/eDP cable is likely frayed near the hinge.

  4. Reseat/inspect connectors (only if comfortable): power down, remove AC and battery, ground yourself, then carefully reseat the display cable at the motherboard and inspect the cable for broken strands or pin damage. Avoid touching CCFL tubes or inverter circuitry; those carry high voltage.

Interpretation and next steps: a faint-but-present image plus angle sensitivity usually means cable or inverter/backlight failure. Older panels with CCFL have separate inverters; newer LED panels usually require panel replacement or an LED-driver repair. If the inspection is outside comfort level, a local repair shop can test the panel/inverter quickly.

Safety note: always remove power and battery before disassembly and avoid cracking CCFL tubes.

Sounds to me like your backlight is starting to go. I would suggest checking your contrast / brightness... but you say that the screen turns on for a brief moment, and then goes faint, so that's likely not the problem. Unfortunately, replacing the backlight is a fairly expensive and tedious job, and you might be better off just replacing the whole lid (screen). Good luck and let me know how it goes.

The problem sounds like your display has gone. As you have mentioned, you can hear the computer booting up n you could see the images faintly on the screen.
