What is replace of this diode here 208

400 volt capacitor how to know its leckage or damaged



one day my own digital satellite reciver not working

itry but not fix

i went to technican and he only change the 400 volt capacitor

my capacitor was like new one


my question is how to know its leckage


i have analog and digital ...

the best procedure to check ultra fast diode by analogmeter

what is the best procedure?

how to know whith analog meter the diode is short or leckage

how to know the zenor diode how much watt and how much voltage

how to know the transistor is fet and how to check it whith analog or digital meter

the transistor is short or damaged. and what is the best procedure to check it powerup or poweroff

how to check the regulator ic is short or open or lekage

THE IS INFORMATION IS

LM317T
CC01P VW
MAR 507


THE IC IS IN MOST DIGITAL RECIEVERSE

PLEASE TELL ME WHERE TO PUT RED AND BLACK PROBES OF METER IN IC TO CHECK VOLTAGE IAM NEW IN THIS FIELD

how to check 400v capacitor whith analog meter is breakdown or not

how to know the transistor is npn or pnp


pleasw whith full detail
