As long as your computer boots normally and has the remote service enabled and/or running, your pc should be accessable via remote connection.

Sounds like the inverter is out. Try that first.

3 scenerios, depends on what kind of graphics chipset you have.

If your laptop has only an integrated graphics unit (IGP), when that chip goes bad, you will have no display, neither laptop LCD nor an external monitor (connect to VGA out or HDMI out of laptop).

If your laptop has a CPU that includes graphics processing on the same die (e.g. latest Atom chips), when that chip goes bad, you will likely have a non-functional computer (not just the display).

If your laptop has both an IGP and a discreet graphics card internally (usually for high end gaming laptops), then it will depend on which chip goes bad and how the laptop handles switching between the chips. Usually, laptop like that will use the IGP primarily to save energy, until when there's high graphics demands, then it switches to the discreet chip. If the discreet chip fails, the laptop will fall back on IGP, you will still have display both LCD and external. If the IGP fails, will the laptop switch to use the discreet chip solely, that all depends on engineering -- if it does switch to it, then you have both displays; if it doesn't, you will have no display at all. If both fails, then of course, there will be no display at all.

So, as you can see above, none of the scenerios above will likely yield your situation, i.e. LCD no display, external display's OK. In another word, the repair shop you went is bullsh*t. Get your laptop LCD repaired, you should be OK from there.


Edit: I was talking about laptop's LCD display and external monitor display (connect via display cable) above. But if what you meant by "remote monitor" is remote access to the laptop's Windows desktop (assume you're running Windows) through network, i.e. Remote Desktop, then yes, you could have a fail card and still have remote desktop display. That's because the remote desktop could be using the CPU to generate the display, so it's unrelated to GPU. But I am not 100% sure on this.

I agree. It certainly sounds like the shop is giving you the runaround because they don't know what the FSCK they're doing.

As Pirate says, it's usually the inverter for the backlight that goes out first. If it's the whole screen, it might cost you a bit more to repair.

Good, that means my conclusion stays -- your repair shop is bullsh*t. ;)

That only happens if you have a laptop with both IGP and discreet card. Nvidia, the discreet one, goes bad. Laptop falls back to IGP, but same time, your LCD's gone, too. How likely is that?! May be your shop fuxor the card, as they open up your laptop. ;)

What model laptop you have anyway?

Try replacing the inverter first!

FFS. This is the cause of the laptops LCD not working in most cases.

I am going a little beyond the scope of the original post question. Here is a good read for tech heads interested to know more about switchable graphics (IGP + discreet).
http://www.pcper.com/article.php?aid=868&type=expert
One sentence in it says: "The hardware situation wasn't any nicer; in fact notebook designers had to deal with additional hardware multiplexers between the displays (both integrated and external connections) and both GPU options. "

So depends on the laptop manufacturer, they could mux one video chip to just one video out. But I truly don't think the original poster's situation is this complex. At least, until he provide us what model laptop he has, then we can be clearer what video chip(s) he has.
