Hi,
The SF (Scan Fail) LED has two "neighbours". One is the indicator for the presence of the -17V from the SMPS board. The other one indicates the presence of the supply voltage for the Convergence circuits (+CONV) which is generated on the G2 board itself.
So this board has three functions:
- Provides the G2 voltages
- Gives diagnostic output through the LEDs
- Generates the +CONV/-CONV/+FOC voltages for Convergence and Focus
Seems they ran out of space on the SMPS module...
Regards,
