Hi all
I have a pair of monitors. One of them is shorted (immeduetly blow fuses)
I cant find any schems.
I start dismantle the bridge rectifier and both filter caps. All looks good.
"Insted" of output transistors, its have two (and same) IC's.
PM93AF LM3886T.
Any advice what to check?
I tried to connect thru DBT and make some measurements, but i think because of the transformer, the loop is closed already before everything and the pcb barely get voltages (no voltages across seconday)
Thanks
I thought of comparing with the other orderly monitor, but better to wait with it and not damage it mistakenly also.
