Brand: Apple
Model: iMac 27'', Late 2009
Graphic card: AMD 109-C29657-10, GPU: 216-0811000

Hello!

The customer sent me the mentioned graphic card, which sometimes display vertical lines in the picture, sometimes there is no video at all.

Question:
Is it enough to reball the GPU chip, or it should be replaced with the new one for the permanent repair?

It must be replaced for the permanent repair. Reballing lasts temporarily (an average of 5 months for your chipset). But some small percentage of chipsets last incredibly long after reballing, even above 12 months.

It seems someone has upgraded a graphics card - Radeon HD 6970M was factory installed on 2011 iMacs only.
