2nd UPDATE:
?
i checked the voltage upon powering up with the switch on IC101 which should provide 3.3V under normal circumstances as i understand the process.? The max i get at the input of IC101 after switch on is 500mV, then trickle down to 0.? At the output, about 300mV then zero.
?
Q101:? in diode mode (DMM) i get:?
D-G+ = OL ???????????? G-D+ = 2.97V
D-S+ =? 0.626 V???? D+S- = 2.92V
S-G+ =? OL????????????? S+G- = 0.626V
?
Q102
D-G+ = 2V ???????????? G-D+ = OL
D-S+ =? OL ? ? ? ? ? ? D+S- = 0.64V
S-G+ =? OL????????????? S+G- = 0.64V
?
be advised i'm still quite a newbie in the realm of transistor testing.? My guess was that one of those was not letting current trough to IC101.
?
Any ideas anyone ? Many thanks,
