Hi Dave,
Thanks for the generous offer!
I've been in touch with someone local who does a lot of SMD work. He's going to have a look and if he doesn't feel comfortable with this project, I'll be sending it to you!
Regards,
Stan

I have an HP 58503A GPSDO with the optional VFD display. Recently, the
same segment in each of the digit positions has failed and is always dark.

There is a HV518PJ 44-pin SMD chip that functions as a 32-bit latching
shift register to drive the VFD segments, and I think this chip is the
most likely point of failure.

I've posted photos in the folder "HP 58503A Display Board" of the
failed display and of the display board showing the HV5818PJ and the
surrounding SMD components.

I have ordered a replacement chip, but I don't have the skills or
equipment to remove and replace it. Can anyone point me in the
direction of someone who can? I am in San Diego.

I'd be happy to take care of that for you Stan, if you don't mind sending it to Pittsburgh. I do surface mount work all the time.
