Re: Apple Macbook pro A1707

Whats the history of the machine, has someone else worked on it before, was it you or someone else who knocked the resistor off. Did you check that the serial number in the bios matched the one on the case

Re: Apple Macbook pro A1707

1) What is the logic board number ? It should be of the format 820-xxxx.

2) Did the display ever work ?

3) A1707 is impacted by the 'flexgate' issue with Apple. The cables they applied for the LCD display were too short and over time, the LCD interface cable breaks causing this event.
