More Power Supply Problems with the IMA4406

DateFriday, May 17, 2013 at 9:34AM

I think that Power Supply problems with the IMA4406 are going to make it on the 10 Most Common List.

This IMA4406 was delivered to us in a completely failed state.  While looking over the unit, I noticed that all of the main Power Supply capacitors had tented their tops.

This means that it's likely that all of them have failed.  This is somewhat unusual, though I have seen more and more units like this.

After the capacitors where removed I checked them with an ESR Meter and I found that all of them were internally bad.
