When i move the screen of the laptop the sound goes off

That sounds like exactly what it is. I'd check to be sure your connectors are tight and that the cord(s) are in good shape. Look for damage where it goes into the device and at the plug. Replace as necessary.

You have a defective graphics cable - the cable that goes from *********** board to the back of your TFT screen. Requires a tech to rectify

that sounds like a video card error. if you can disassemble the notebook, check for loose connectors, particularly the connector that goes to the screen.

sounds like u need a new inverter

Your ribbon cable to the screen sounds as if it is damaged, or crushed, when you move the screen it probably breaks & remakes the connections again.. when it gets moved it breaks again and so on. I would recommend you check this out, perhaps a replacement cable may be in order.. Otherwise get a serviceman to have a look. get a "Quote" though before proceeding.

This sounds like you have a short in the LCD ribbon cable and it will need replacing, in most cases you will have to replace the screen but if you can find the exact ribbon cable, replacing should do the trick.

Sounds like the LCD display cable is either loose or broken. I would suggest that you bring the unit into an authorized service center to repair your laptop. Not knowing how to open and repair the unit could prove very costly.

Hello,

It really sounds like you have a short in the ac adapter. Laptops dim the backlight on the screen when on battery power and go full brightness when on AC. I think your adapter is going on and off. When it is on the screen is on full and when it goes off the screen dims down a bit. You could have a bad adapter, most likely, or a bad charging jack in your laptop. Check the adapter first, just use a multimeter set to voltage. Read lead goes to the center pin and black lead goes to the outside metal contact, you should get a reading of 18 to about 26 volts. Move the wire around near the plug that you are holding and keep checking the readout. I think you will find the voltage dropping as you move the wire.

I hope this helps, If so please rate my solution.

Sounds like the ribbon which runs between the screen and base is being nipped or is not making a good connection. This is a common problem. If that is the problem you may find that by adjusting the screen you can actually get the picture to show again which will confirm but obviously it will continue to happen.

Most laptops have a narrow panel above the F keys which snaps off and reveals the ribbon underneath. Check the connection is pushed in tight and also that the ribbon isn't being nipped, reposition to stop this happening. If it's been damaged then obviously you will have to replace it.

it sounds like your most likely having trouble with the hibernate feature try this
start>>control panel>>power options>> click on the hibernate tab
un check enable hibernate mode
this should fix your issue
