    Has this problem been sorted out for you? If not what was the last thing you were doing with the laptop before this happened? Has it bee dropped in the past? Can you still see anything at all, even a faint image? Have you tried plugging in an external monitor?

    Regards

It sounds like the LCD back-light is out. There are two ways to fix this, neither are pretty.

1) (Cheaper, so try this first) - replace the inverter assembly.

2) Replace the display. This can easily exceed the value of the laptop, unless you can find one cheap. I've done it by finding a damaged machine on eBay (bad motherboard, good display), paid about $200 for the whole machine, instead of $500 for a parted-out display being retailed by a parts dealer.

Both operations involve major disassembly, and removing/installing the new display is tricky - - there are very delicate wires leading from the display to the plug that attaches to the circuitboard that thread through the hinge and into the chassis. Break these wires, and you've just wasted the display.

That said, _Excellent_ instructions are available at

www.ifixit.com - you can download the PDF and print it for reference before you get into the dis-assembly.

Good luck!

Fading colour


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

LCD is on...seems like backlight is not functional; when external monitor connected, boot-up and bios screen visible. After boot-up, screen goes to "power save" mode and will not return


Use the 'FN' key (blue coloured?) and one of the other blue-coloured keys to "toggle" the video:

1. LCD only
2. external monitor only
3. both LCD & external

After boot-up, Windows defaults to "LCD only", and so the external monitor goes to "sleep".

Hp dv9000 switches on to show coloured lines on screen.


Hello

My first guess is that the screen circuitry has gone bad - although fixable. Use an external monitor to verify this. If the external monitor is fine then the screen circuitry is bad, if the external screen shows the same problem then the video chip or associated circuitry has gone bad. My company fixes these all the time.

No display, clipping sound appear


The clipping sound is the internal safety switch that keep shutting down the monitor.
It means there is an internal problem on the main board (overvoltage, bad component , short).
Try unplugging power cord and leaving it unplugged two or three hours, this will reset ICs by draining power completely from circuits, it is called hard reset, it rarely works.
CRT monitors waste up to 15 times more energy than TFT screen, if your CRT starts giving troubles, then it is a good time for upgrading it to a new TFT.
