Hi i have a sony vaio VGM-AR51M laptop
it has a 19" screen and this week the screen has started to falter.
1 it started flickering lines across the screen then the screen started changing colour
it looked like someone had placed a blue colour across the screen the icons we there but unclear.

2. now it is opaque (whiteish) like you are viewing the screen through a mist, i can see the icons but they are not clear, everything else is working fine just the screen
any help and advice would be appreciated please thanks guys

is this an expensive problem to fix?

Try uninstalling your video drivers, via Device Manager...then rebooting.

Start/Run...type devmgmt.msc and hit Enter.

Scroll down list to Display Adapters...double-click it...go to Driver tab, click Uninstall.

Reboot.

If you have Drivers CD which came with system, use that to reinstall the Video drivers.

If not, try following the bouncing ball at http://esupport.sony.com/US/perl/model-find.pl?mdl=vaio vgn ar51m &PRODTYPE=32,33,63,71,7,102,26,80,72,44,55,27,74,84,57,61,108,109,103,89,10,113,35,78,48,77,106,29,50,39,64,114,12,41,58,52,81,60,45,66,73,101,76,86,62,54,67,70,68,2,17,1,88,100,82,110,25,28,83,59,69,112,49,24,104,53,79,22,42,46,13,105,6,85,3,36,9,51,111,47,38,4,34,37,43,5 .

Just to add to what Louis said.......

Do you have a external monitor you can plug in as a test to see if it is a screen issue or if the video going to the screen is the problem?

Thanks
Roger

Just to confirm, When you hooked it up did you use the VGA connection or the HDMI port. There is a possibility that they are different graphics. If you read below you will see why I asked how it was hooked to the TV set. I use VGA to my TV rather than HDMI, however I could use either. In the first quote it works fine with teh TV and poorly on its screen.

If you go into the Device manager what shows for video adapter?

For XP right click on my computer and pick properties then hardware then device manager
For Vista / Windows 7 right click on Computer and on the left choose device manager.

BTW when I look that laptop up is shows a 17.1" screen and 19"
Are you by chance in the UK?

When I do some looking I see this sort of thing
From: http://www.nvidiadefect.com/sony-viao-vgnar51m-screen-problems-t856.html

which has now developed a screen fault that I can only describe as similar to a television with very poor reception or a bad ariel.

You can see some stuff on the screen but obviously you couldn't work on it or use it for long periods I have however connected the laptop via it's HDMI port to a Panasonic plasma TV and the laptop works perfectly connected to the TV.

Further on

to the lounge it worked perfectly for about two minutes after it re-booted itself on opening but it's since gone back to the dodgy display thing and I can't get it to display properly now except when it's hooked up to the TV.


If in the UK this may be relevant: http://www.nvidiadefect.com/post13.html#p13

My Google search phrase. VGN-AR51M screen problem

It does appear as I was afraid it might that the problem is not the screen but rather the built-in graphics on the motherboard.

I can't really blame Sony for this one as it has cause problems for Dell, HP, Compaq and others.

Due to the nature of the defect you may be able to get resolution from Sony. Sorry to be the bearer of bad news.

Good Luck.

Hi rotor 123
rechecked connecting to the tv via HDMI the view from the tv is clear and clean as it should be.
Thank you so much for your research and for finding what the problem is with the laptop.
i would say i have the same problem as the others using the laptop screen is exactly like viewing a bad tv channel.

had laptop 4 years no proof of purchase due to moving house in that time gutted.
I am in spain not the uk. i have a spanish laptop but got vista converted into english for me.

any idea roughly how much to change the card? is it worth it as this cost a pretty penny and i am loath to just throw it away.
device manager shows nvidia Geforce 8400M GT
thank you for all your help
regards
bill

I can not really tell if it is a add on card or built into the motherboard. I don't have a good source for Sony service manuals unfortunately.

Since searching ebay for a video card was unsuccessful. I'd suggest calling Sony parts and see what they say.

Wish I could be more help

Cheers

Hopefully it is just a loose hard drive.

When you started to disassemble it I hope you pulled the battery & AC and then hard drive and then the optical drive before going further.
The order I just gave are generic but usually accurate.

The problem could be a simple as a loose hard drive connection. Is there a cover on the bottom over the hard drive?
If so being very careful try reseating the hard drive. Be careful not to press on the label side of the drive or the opposite side.

Laptops are very delicate, especially the connectors for Keyboard, touchpad, speakers etc.

hi rotor 123
i unplugged ac removed battery removed screws looked at taking the laptop cover off
decided against it as i was not that confident and put all the screws back in place.

I did not touch anything else but what you say may be right a loose HDD connector (fingers crossed.)
off to the repairers tomorrow.
thank you for your help and advice
