Connect it to a regular monitor - if it looks good your laptop screen is bad.

If the external monitor is bad, then the video hardware in your laptop is bad.

If you right hand mouse click on your desktop picture, a menu will become available. Click on Screen resolution and then Advanced settings. There will be options inside that window to allow you adjustment of the display.
Hope that helps.

Hello,

The problem is not from the inverter of the laptop. It is the module that is faulty, the module is like a flex in the laptop that assists in getting information from the motherboard to the screen, if it is faulty, it will start showing weird colors or start having some screen malfunctions.

Have the module replaced and the laptop will be in good condition once again. I had such experience with my HP530 and i replaced the module, trust me it worked perfectly fine.

Take care and good luck

My Hp Compaq 6820s don't start when I press power button.


This simply means that the battery is dead. Pull the battery out and try to start it again (with the power adapter plugged in obviously). If it starts up, you need a new battery, if it does not start up you may have a bad power adapter or broken power jack.

Hp 6820s will not power up.


Try removing the battery and see if the light is normal.
If so, you may need to replace the battery.

The screen of my laptop


If you get weird colors and poor resolution, then it is probably just the driver, that need reinstalling, in this case you will be able to read text normally, only photos look bad.
If you do not have the disk you can reinstall driver from factory website.

If you instead get only a bunch of floating stripes on the screen , then there is an hardware fault.
Either the connector/flat cable to LCD, or the video adapter.

Connect an external screen to laptop.

If external monitor works, then it is probably the video ribbon cable, the connector, or the LCD. Still not too expensive to fix.

If the external screen does not work, then it is the video adapter that is integrated on motherboard.
In this case check your guaranty terms.

If you need service you can call the number listed on the owner manual.

Vertical lines in my laptop screen


Try using an external monitor,every laptop has a blue VGA connector,just connect a monitor there and check is those lines
disappear,if it does,probably you have a problem with the internal connection of your monitor to the motherboard.
