HP 8935 E6380A wont power up

 

Hi all,

My trusty E6380A failed to proceed this morning and preliminary investigations as to the cause prove zip.

Do these things have a common fault I could go look for ?

Any pointers to what might be the cause ?

Any path to resolution gratefully appreciated.

Service manuals don't have schematics so that's not helpful.

thanks

Tim
 

Hi all,

I was pointed at the common culprit via Rick@Amtronix.

There are two small vertical PCB's on the main power board, on each of them is a 47uF electro that often fails. Both of mine measured about 12uF. Replacing both brought the unit back to life.

regards

Tim
