Isolating power supply issue is something very useful. As a beginner I have following questions regarding inputs to power supply.
As I understood PS_ON, DIM and BLK_ON are inputs to the PSU.
These are my problems.
1. Can we turn on power supply without logic board by connecting following pings?
* 3.3V STB and BLK_ON (via a resister) AND
* Connecting 3.3V STB to PS_ON for a short period
2. Do power supply sense current to the logic board and T-Con?
Can we turn on power supply without backlight (with logic board connected or not)?
