Latitude D620 Fuzzy Screen

The screen has suddenly become fuzzy.  In BIOS and in Windows.

When I attach an external monitor the information displayed there is without problem.  But of course the laptop monitor is still fuzzy.

Thank in advance.

Hi

What do you mean fuzzy? much lesser brightness? Then there is a good chance your LCD inverter has died on you. (i cannot recommend it but sometimes tapping the top (lcd) cover a little helps when it is not connected 100%, i guess your inverter is located on the side of the screen but you cannot see it)

What version of Windows does the laptop have?

Could it just possibly be that the resolution needs set back up higher? Sometimes when it gets set to a really low setting it can appear fuzzy.

If you right click on the desktop you can go to screen resolution (Windows 7) or properties (Windows XP) and adjust the screen resolution.

If you don't think that is what it is let me know!

Wow that looks like a wrong LCD cable, was it changed recently?

If not i think you need to open up the machine and check if the WXGA cable is firmly attached to its connector.

The screen is fuzzy in the BIOS also.  Adjusting the resolution doesn't change anything.

You could go for broke and try to update to the latest drivers.  

If that does not help does this laptop have a video card or is it built into the motherboard?  If its built in then you might be looking at a bad LCD or faulty motherboard.  I would check to see if the laptop is under warranty and open a ticket with support.

Could also boot to the dell diagnostics utility and run their test, it does the video right-away i believe depending on the age of the laptop.

It cannot be the graphics card, connected to the external monitor displays correctly.

Is believe a) the cable is wrong (but have doubt since poster is not mentioning it having replaced) b) WXGA cable is not connected firmly or c) some fluids went into the machine.

Could be just the LCD is going bad.  D620 should have a pre-boot hardware diagnostics you can run to test all components.

The clues here are - it's recent, an external monitor displays OK and it looks like this in the BIOS.

The Display being affected in the BIOS means it's not Windows so changing drivers isn't going to touch it.

The external display says your graphics chipset is OK

So you've got a hardware fault between the graphics chipset and the LCD.

Most likely it's the LCD cable which runs under the hinge.  Does the display quality change at all if you open and close the lid putting more or less tension on the ribbon connector?

They aren't difficult machines to strip down and replacement cables are a few $$ if we can be sure that's where the fault lies and not in the LCD itself (which is more likely to have some kind of obvious history of damage/dropping)

try opening the laptop, and remove/inspect reset the video connector - it may be loose, or have a bad contact

If it's not a loose connection, then the screen is bad and needs to be replaced. I've done quite a few of these and it has always been a bad screen.

Looks like you can pick one up for around $35.

Ordered a new screen and cable assembly.  This was my thought to start but I like asking y'all too.  Will repost once part is in.

I replaced the LCd, inverter, and cable today.  The video is still fuzzy.  I assume it is a MB issue.  Looking for confirmation.  Thanks

Scott CSenior EngineerCommented:
Just to be 100% sure.  When you connect an external monitor everything look ok...is that correct?

nobusCommented:
that is in his first post
so i assume he's correct  - mobo problem

Scott CSenior EngineerCommented:
I know that. I was just confirming.

If it is then, yes, I would go with system board and either replace that if cost effective or if not, replace the laptop.
