Hi All,
I have a MBP 1.83 GHz A1150 2006 (model MA634F/A) equipped with MLB 820-2056-A. It has no backlight AND no display but it works fine on an external monitor. I took apart of it and checked several things like LVDS and inverter cables. They are OK. I also has a look at the inverter 612-0020-A. When powered on, there is only 12V between pin2 (wired on good fuse F1) and pin3 also connected to pin1. 2 other pins 4 & 5 have no voltage. In these conditions, there is no voltage on the high voltage output.
So basically I was wondering what your ideas are about what it could be: LCD screen (LTN154X7-L02), inverter, MLB issues ... ?
Thanks in advance for your help.
