Narrow down the problem of no-image on Apple Cinema Display 24 in
The 24-in monitor doesn't show anything, so I tested the voltages inside. I appreciate if anyone can help me narrow the problem down to the root. Plugging in the USB, my Thinkpad P50 laptop can recognize the Audio and iSight camera. But plugging in the mini-DP cable, no recognition of the monitor, and no image was shown. No background light on. Model # A1267.
The biggest problem in the voltage readout (testing point diagram can be found on Page 16 on the guide):
LCD and LED part:
TP81: 0V (should be 24.5V),
DC in part:
TP11: 12.7V (should be 24.5V),
TP12: 0V (should be 24.5V),
TP13: 0V (should be 12.0V)
I read through the forum, there may be some problems with the fuse on the logic board or the power board is broken? I am sure which is more likely to happen. I don't know where is the fuse located neither the data sheet of the fuse.
Is dit een goede vraag?
