hi there i am learning my self since a lot of time...

i am measuring output voltages of the power supply(internal) on one monitor.

The board is 715g2892-2-3.

I see on heat sinks only one Q and one diode - D906.

How to understand which is the other rectify diode ? i have 5 volts on D906. the one i see in big housing is D902 but there are 16.24 volts that are not so close to 12v. in the photo in guide i see 13.68 which probably seems fine without load.

Thanks

question #2 -

i see 2 3pin schemes on mainboard - 903t63 and ajz137. Are the both of them voltage regulators ?

On pin 1 2 3 i see
0 3.26 5.03

0 1.78 5.03

 

the monitor is philips 191v. where to locate my picofuse ?! on the small fuse i have about -150v which is strange.

I hope some good guy to answer my questions
