Welcome to AAC.

Would you care to share some more info on the subject ?
Like, what type of PSU. It's model number or any documentation if you have any.
Some pictures would be nice.

Hello,

When you still have warrenty, try to get it fixed by extech.
When you have no warrenty, nothing is lost and open it.
