Question about Sony VAIO VGN-FS640W Notebook

Sony Laptop Screen goes Grey

While using the laptop the monitor will occasionally go grey. Power is still going to the monitor thus it isn't black. I don't think it is the inverter because I can't read anything on the monitor (my HP inverter went bad and this is different). Also, it will work again if I put the computer to sleep/suspend it/turn it off and then wake it up/unsuspend it/turn it back on. I also tried an external monitor and that works.

Any help would be appreciated.

1.What I need you to test is...When laptop monitor go grey try plug external monitor and see that it work fine or not ??
2.Incase it work fine try to give a little tap behinde the laptop monitor and see that any changes...keep try and harder and see

3.Incase if you gave a hard tap also and its still the same but external monitor work fine then....I think you have problem with your LCD monitor coz there are chips that control the LCD crystal and maybe when it goes hot it behave this way....in this case you can't change the chip...you have to change the LCD.
takecare.

My Hp notebook screen is black,sometimes it fades in and out black to grey then to black.how can i fix it


Connect your laptop to an external monitor and switch to monitor. If the external monitor shows the desktop, then the complaint is in the lcd/led display unit means the screen. Replace the screen. If the external monitor also shows the complaint, then it is normally due the mch(media controller hub) . It comes as separate card unit in some models and onboard for some other models.Only an experienced technician can solve that issue. In some rare cases it is due to a corrupted BIOS. Reply if this helped you.

You can check the screen using an external monitor. If the external monitor is OK, the internal screen is faulty. If not, you may have a GPU issue.

Grey screen


Take it in for support at your nearest Toshiba Repair center. If it was a desktop you might've been able to service it, but since it's a laptop, you're better off not messing with it.

Toshiba Satellite A505 - Most of the time when I turn it on the screen is grey, with no text.


This sounds like a bad display on the laptop. Hook up an external monitor to the vga port on the laptop. You may need to toggle the display to output to the external monitor. This is generally accomplished by pressing the "FN" key + one of the F# keys. Look for an icon that resembles a monitor or it may say LCD. If the graphics display correctly on the external monitor, then you will need to replace the computer screen.

My Toshiba A205 laptop screen goes grey


Check the LEDs located on the battery, if they don't light sequencely or make some blinks, your laptop is having a battery issue. If everything is OK with the battery then the problem is in the leads of the motherboard that make contact with the battery or in the circuits that manage the power of the battery, located in the motherboard.
