Black Screen overall and starting sound + vent
Hello,
i have some new problems with my imac. after i send it to repair service (not apple) and they fix the FI-X30SSL-HF on the logicboard (replace it with a new one). my imac did the boot sound but nothing happend on the screen. extern dvi screen doesn´t work too, but it works before i send it to the repair service (the dvi on an extern monitor).
they said to me that the reason is:
a. the vga could be defect OR
b. it doesn´t work because i put the FI-X30SSL-HF back on the board and two pins connected each other and give a negative electric feedback on the board. but it works before i send it to them (the dvi, not the intern lcd).
what do u mean could it be?
Is this a good question?
