Re: Smasung SyncMaster 913N Monitor wouldnot display images
Folks,
I've given some wrong info.
The second signal cable Ssc described previously is fact an extension cable, therefore everything regarding this cable is not true. Sorry for putting you people in the wrong direction.
I've since taken a few readings.
Output of monitor with no signal cable connected.
Pin 6 – 5 Volts
Pin 11 – 5 Volts
Pin 12 – 1.3 Volts
Pin 13 – 0.8 Volts
Pin 14 – 5 Volts.
All the others – 0 Volt
With signal cable plugged into the monitor but not connected to the computer.
Corresponding readings are as follows.
Pin 6 – 0 Volts – (Compared to 5 Volts without the cable !!!)
All other remain the same.
Pin 11 – 5 Volts
Pin 12 – 1.3 Volts
Pin 13 – 0.8 Volts
Pin 14 – 5 Volts.
All the others – 0 Volt
Signal cable configuration - Pin 2,6,15 –Connected to the body of the plug.
Have marked the power supply capacitor.
Volts across capacitor of the power supply.With no signal cable.
Cap 1 -12.5 Volts
Cap 2 – 5 Volts
Cap 3 – 5 Volts
Cap 4 - 12.5 Volts
Cap 5 - 0.075 Volts – (47micorfarad rated at 35V - ???).
Cap 6 – 3.5 Volts
Cap 7 -12.5 Volts
Cap 8 -12.5 Volts
Cap 9 – 5 Volts
Cap 10 – 5 Volts
Cap 11- 12.5 Volts
Cap 12 – 350 Volts.
With signal cable plugged into the monitor but not the computer.
All Volts reading are the same except.
Cap 5 – Gone down to 0.0 Volt (Zero) – (47micorfarad rated at 35V - ???)
Could this be the area at fault?
Don't have any circuit diagram.
Can anyone put a finger to it?
