I recently bought a Samsung SyncMaster 2494HM LCD monitor. Out of the box, I plugged it into my HP Pavilion dv6000 laptop using the VGA cable, and things worked perfectly. About a week later, it stopped working.

I brought it into Samsung after service to try to get it fixed, but when they plugged it into one of their computers, it worked without a problem. While I was there, I hooked it up to my laptop to show them the problem, and after 10 minutes or so of playing with it, they were unable to get it to work. However, I am in South Korea, and the laptop language is English, so they may have had some trouble with that.

My OS is Windows 7 32 bit. I have tried all sorts of options in the screen resolution settings, but cant get it to show. The screen looks like something is happening (it flickers a tiny bit), but it never shows anything. Also, on occasion when I first plug the monitor into the laptop I can see the desktop for a few seconds.

This is very frustrsting since it did work for a while, but now I get nothing. The monitor is just taking up space. I'd be grateful for any help.

Does another monitor work OK on the laptop?

No. While at the Samsung service center, we tried plugging it in with no luck.

Then it appears the problem is with the video in the laptop. DV6000 series laptops with nVidia chipsets had problems:

There is no video on the computer LCD panel or external monitor."

Does this mean that there is no known way to fix it?

It really gets me that it worked for a week or more and then just stopped. Any suggestions on how to fix?

Thanks.

Well, if it is the problem with the nVidia chip, then the only solution is to have it repaired, which would not be a cheap repair.

The failure is due to the video chip being run too hot. Since modern chips control their power consumption by disabling sections that are not being used, running the secondary monitor is likely to have increased its operating temperature, and I guess a week of that was all it could take. Is the BIOS version earlier than F.3D?

Oh, OK, thanks. I know that this computer does run really hot.

The BIOS version is F.16...I think thats before F.3D. If the chip is burnt out, is there any reason to update the BIOS?

Yes, that is an older BIOS version, and if you want to continue using the laptop as it is, it would be best to update to the current BIOS. The later BIOS runs the cooling fan at a low speed during idle times where the older BIOS stops the fan. So operating temps are lower and may help stave off any further failure of the video.
