The display on my MacBook has gone dim and has a big vertical chunk down it that is totally black and some other vertical lines.
I opened it up to see if the display connector was loose but it is not.
I also tried connecting the displayport to the HDMI on my TV but that did not work.
I am happy to replace the LCD assembly but i dont want to buy one if the problem is on the main board somewehre.
Это хороший вопрос?

ZZZ is correct here your problem is the display.
What likely happened is you banged the lid or sat something heavy on it. The electrical connections between the LCD glass and the driver logic on the back broke.
These are hard displays to replace, I would recommend you replace the complete lid assembly.
As you didn't give us your exact model info I can't point you to the IFIXIT guide or the needed part. If you do we can offer that to you.
As to why your HDMI connection to your TV failed you might want to check which HDMI port you used as well as what you need to set within the TV to activate the port. The other possibility here is the mini DisplayPort to HDMI adapter you got is bad.
Here's the IFIXIT guide for your system: MacBook Air 13" Mid 2011 Display Assembly Replacement and here is the full assembly: MacBook Air 13" (Late 2010/Mid 2011) Display Assembly

sorry i did add th model number in a comment to another answer but that got deleted its an A1369 :)
I watched a Youtube video on changing the LCD and it involved a razor blade so I am definielty out on that one!
I guess I just have to decide if it's worth the cost - but at least now I know that will be the solution. Thanks!
@Ben - Sorry guy, we really need the last four digits as the model info covers a few different units ;-{ A1369 models

It's not the cable because this uses displayport, not LVDS. LVDS can do this - displayport is an all or nothing protocol.
It's not the graphics since this machine has integrated graphics in the CPU - Intel graphics doesn't die like the junk overpowered undercooled AMD/NVIDIA chips have for the past nine years.
It's the screen. Replace LP133WP1 and best of luck!

I realize this is an old thread, but there is a lot of bad information here, and it should be corrected.
Macbook airs DO have an LVDS cable connecting the motherboard to the built in monitor. Display port is used if one attaches an EXTERNAL monitor. And it is very common for the LVDS to get messed up, resulting in exactly what we see here in the pics. It's frequently the result of picking up the laptop by the monitor frame, such can cause stress on the cable. In other words, it's the cable, not the monitor.
Unfortunately fixing it almost always involves opening up the monitor frame, which requires a hot air gun, some spatulate tools, and great deal of patience. It's delicate work and easy to screw up. Check out Louis Rossmann's youtube videos on the procedure. It's a pain in the ass.
Some folks have had luck kludging a solution by applying light pressure to various parts of the frame, or by inserting a business card between the inside edge of the frame and the monitor, but it seems like a temporary fix.
If you can't open the frame yourself, or find a ship to do it for you, see if you can find a whole replacement lid assembly on eBay or something. Unfortunately, they aren't cheap typically, and neither would a repair shops fee. $150 or more, from what I recall.

@urville - Sean, Sorry guy the problem is the display. For reference watch this vid jump to Picture D LCD Display Symptoms & Causes, same issue here. This is the result of the bonding of the electronics to the glass (often called tab errors). A bang or having something heavy sit on the lid is the common cause.
As for internal display cable: This is a bit confusing for many. The cable its self is a ribbon type and both LVDS and iDP use this type of cable so one can't really use the term 'LVDS cable' without making sure the signaling is LVDS. So what is it here? LVDS or iDP? The clue is if the system has a Thunderbolt interface, if it does its always iDP. If it has a mini display port then is could be either depending on the age of the system. In this case this system has iDP which you can find on the systems schematic.
If it was the cable LVDS would give you solarization or colored stripes. iDP wouldn't show an image or the image would fragment like your over the air digital TV signal does when the stations signal is weak when the connection makes and breaks.
As to the kludging of pressing the display or bending the frame, all thats happening here is the tab contacts are re-established causing the break to be pushed together enough the signal can get though. Sadly, all of the messing about will only work so long, time for a new display ;-{
Replacing the LCD alone while it can save some money often the defuser sheets get dirty or creased which leaves a dark splotch. You also risk damaging the cover glass and the frame. The best and less work job is just to replace the entire display lid assembly. Trust me I've tried a few times and I have yet get one to look factory fresh.

Can you give us the last four digits of your serial number so we can correctly identify your system.
