[TechAssist] Re: CS35707-M1GA-All red screen-( No Blue and Green output on IC6f01)

The IC's are a common failure. Just completed one with the same symptom
before my vacation. Be sure to install the diode as Jeff mentioned. This is
a money maker and easy fix. Worst part is removing and installing the rear
cover.
