The strangest thing happened a few days ago. The display on my A10 started shaking or bouncing quickly vertically. I went to bed and when I woke up the next day the LCD screen was black. Upon closer inspection I could barely make out the display, as it should be, but almost completely black. I plugged in an external monitor and it works fine - the color and brightness are normal. If anyone could suggest an action plan to resolve my problem, I would be eternally grateful. I don't think it's my vid card as the display is just fine on the external monitor. Does this mean my LCD screen has burned up? I don't get it. Much thanks in advance.

Quick diagnostic guide that builds on the thread: reported a screen that started “shaking” then went nearly black while an external monitor stayed normal. and suggested a couple of likely causes and noted the same symptom. Below is a short, safe action plan to narrow the fault and sensible next steps.

  1. Check for a faint image with a bright flashlight held at an angle against the screen. If you can see the desktop faintly, the panel is still receiving video and the problem is the lighting/backlight side of the display; if nothing appears at all, the LVDS cable or the panel electronics may be at fault.
  2. Cycle the laptop display mode using the display-switch key (Fn + the display key on the F-row) and try booting to BIOS—this tells you whether the laptop is sending a signal to the panel before the OS loads.
  3. With power removed (battery and AC disconnected), gently open the bezel to inspect the LCD cable where it runs through the hinge and where it connects to the panel and the board. Look for frayed wires, cracked insulation, or loose/reseated connectors.
  4. Visually inspect the small inverter board (if present behind the bezel) for burned components or swollen capacitors. If comfortable and properly powered down, reseat the connectors; do not probe high-voltage lines while powered.
  5. If the faint-image flashlight test is positive and the inverter/input cable looks okay, replacing the inverter or the entire LCD assembly is usually the practical fix. If no faint image, the panel itself or its LVDS connector is suspect and you may need a replacement screen.

Cautions: disconnect battery/AC before disassembly; inverter sections can produce high voltage and CCFL tubes are fragile. If unsure, a repair shop can give a quick parts-vs-labor estimate—often replacing the inverter is cheapest, replacing the panel more costly. This sequence should help distinguish which part to replace.

ok i know this sounds really stupid, but sometimes it can happen

im going to say its not very likely in your case because of the shaking/bouncing

but anyway, sometimes the little tab on the laptop, where it senses whether the lid is shut on not, can get stuck, so if you can see the gap where it is, give it a few pokes and see if it springs back up, dont be too violent though.

It'll probably be the inverter... It could be the screen, but it is more rare for that to happen! Go on ebay and buy a new one (probably cost about £20)

Hi Shrek
Just today morning the very same thing happened to my Toshiba laptop. Can you post regarding what you did to fix the problem.
Thanks,
