ASD 3S116 testing: GPU 0 Die Test 1

Hi Guys,,

What can you tell about my problem ?

Revision of iMac Mid 2007 strats up screen goes black (LED 4)

My presumption:

The first issue is the heatsink, then wrecked the videocard (vertical lines).

New heatsink, with other videocard.

Problem with ASD 3S116 testing: GPU 0 Die Test 1

Error: Sensor reading above alarm point. TEST FAILED.

The cable that leads towards the GPU heatsink has two cables.

The connector is not in the best condition.

Can the contact be broken ?

Hope to solve this issue.

Thanks, Arnoud
