Random black screen, sometimes with flashing lines

Texte:

So I've searched and searched… Looking for an answer
 
I recently bought a 13” MacBook Air Mid 2011.
 
Most of the time when booting, it gives me a black screen (no image, no backlight). Sometimes the screen and backlight work on boot.
 
Usually have to do the NVRAM reset. Now, when I close the lid and reopen it, most of the time it is just a black screen with backlight glowing a bit. I can usually close and open it about 6 or 7 times with just backlight and no image before I open it and then I have image and backlight in perfect quality.
 
Some of those times when I open it, I'll have a quick set of whitish gray lines that flash briefly. These lines are completely random how they flash and located.
 
I'm wondering if this is the LVDS cable or a logic board issue.

Ok. I guess my final question would be, can you just buy that chip and have a professional install it to the board or would have to go the entire logic board route? If I have to go the logic board route, is it worth spending 150 bucks on a board? I bought the laptop for 80 bucks.

Any way of spotting board version differences?

So got a new board in and have the initial startup sound but nothing else. No image and no backlight. What is going on now? I pretty much 100 percent guarantee that nothing got broken on install as I'm very careful.
 
Ok. Strike that. Board appears defective. Seller is taking it back. Dan, what parts houses are you referring to?
 
Also, is it worth upgrading to the 1.8Ghz i7 board or not?
