My laptop is 18 months old. Recently when I open it to the normal position it goes black but when I lower it to 45 degrees it works perfectly. What can I do to sort it out or is it going to be an expensive repair?

Re: laptop screen problem
You may have a problem with the flex connector that brings power and date from the body to the screen. Check the following:
1. When it goes black, can you tell if the backlight is still on? (It will be dim, but you can tell).
2. When it is dark, shine a bright light on the screen to see if the image is still there.
Also, check the button that is engaged when the screen is closed. This button simply turns the backlight off when you close the laptop and is usually located at the front or back of the body and may be a small pin, or an opening the screen hook will catch on. Press this button a few times under both conditions.
Either the screen data or backlight has a faulty connection and would require opening the laptop. The price of the repair depends if the wires or flex print are damaged, or the connector may just need to be reseated. You cannot simply tell without opening it.

It is possible that the video cable is chafing in the point where it passes through the hinge assembly. Try reseating the video cable, if that doesn't help, the replacing the LCD cable assembly is the likely fix.
You should be able to remove the LCD hingecover and reeseat the video cable. But hte issue may be a damaged cable going thru the hinge assembly which would require a replacement LCD.http://support.dell.com/support/edocs/systems/vos1500/en/sm/display.htm#wp1179838
One of two things.
Either your inverter gets unpluged (therefore it isn't plugged in correctly in the lappy) unless it's moved to a certain position (so don't shake your lappy or else you might see nothing), those being positions where theres slight pressure on the connector, even though it's loose or unplugged (POSSIBLY faulty, but most likely not, if it turns out it is, other than resoldering it, you'll need to return it for a fixing up.)
The switch that turns your screen off when the lappy closes is faulty (if it's located near the back of your laptop, aka. under the lappy's LCD bezel.
Opening it up and unpluging and pluging in the inverter is probably what the solution is. A tech might do it for free if you're nice (or you could do it yourself, don't loose any screws :) )
Hopefully it is just a loose connection and isn't a big deal at all to fix.

This is definitely a loose connection problem.
Does the screen go completely black or just a part ?
If its just a part, LCD is defective. You may have to change the whole LCD screen. You can get one for ~180$ from ebay
If the whole is turning off, I guess the power cable might be little loose.
You can open the LCD panel and check if you know what you are doing.
Else take it to a normal technician and ask him to open the LCD panel and see it.
Perhaps your connections on the inside have come loose. It may warrant you take it to a specialist to check it over before it gets any worse. Some other person was on here some time ago who had a similar problem and all it was is the switch in the lid. Apparently they tinkered with it by just kept on pushing it back and forwards as if to continue to open it and it came right they tell me that they hardly used it thats why!.
