The dreaded jumping cursor... A possible resolution?

I am the (french) new owner of a "A1181-Macbook"based Modbook (early 2009). I was first very satisfied with my new Toy. Unfortunately I noticed very quickly that the cursor began to jump to the upper left corner (" the cursor goes to the upper left and ‘freaks out’ "). That occurred more and more often, especially with Photoshop (processor heavy software?). Every now and then, I couldn´t use it anymore.

Eventually the problem disappeared... As the screen went dark! No backlight anymore.

As the Warranty expired, I decided to dismantled my Modbook in order to reached the inverter board.

Big surprise when I opened it. The (many) thin cables between the two halves of the modbook were badly squezzed and pinched (I made photos of that and I can post them if required). These cables are gathered at the upper left corner of the modbook on its working position.

In order to check them out, I have put the isolating coat away form the cables where they seemed to be broken. I recoated them with dicker isolating tape after the check up, taped them together and arranged them in a way that they could not interfere with the edges of the two halves.

And guess what? After putting everything back together, The dreaded jumping cursor completly disappeared form my modbook. Not even one time. I couldn´t believe it.

These cables may have caused magnetic fields and interferences with the Tablet at this place. Sounds like an explanation?
