Trying to identify a component in a switching power supply?

[Rodger Hooks]

Hello all


I have an old PC switching power supply with a component labeled DA1 in its circuit board. I have doubts about the components in a switching power supply. So, I need your suggestions which will help for my requirements. I wish for your support and cooperation.

Thanks,
Rodger Hooks

PSU's are a pain in the backside to repair at times and its easier just too replace them

What is the model of the PSU have you googled it and tried to find a schematic for it online?

Wossit look like? DA1?

And what makes you suspect it's the faulty component?
