Diagnosing a faulty, Inverter Cable?

Hey everybody,

I bought my macbook about 6 months ago and woked about right. A few weeks ago when i opened up the screen noticed that it when dark (just the backlight) if it was below a 90 degree angle, the problem started to get bigger and the screen would go dark on almost any position. The problem corrected if i moved a bit the angle, did a bit of research and found out it could be a faulty inverter, i replaced the inverter last week and it worked out fine for a couple of days but today i'm getting the same problem if the screen is below 90 degrees it goes dark (still only the backlight).

Been looking through other questions and i'm finding that it could possibly be the inverter CABLE not the inverter board.

Is there a way i could diagnose this?

I would really like not to spend on a replacement to find this was not the problem. (Like it happened with the inverter board)

Thanks for taking the time to read this!
