| HP3478A Display problem |
| (1/1) |
| davebutler:
Help sought from the brains trust please. I picked up this HP3478A for a song knowing it had a display problem. It flashes up part segment & sometimes th full display for a few seconds the nothing for about 30 sec to min then another quick flash.(See pics) Any help or suggestions would appreciated. Thanks in advance. Cheers Dave B. |

I'm far from an expert but from what I've seen on the HP3478A, the display is impossible to get anywhere from other than another unit with a working display. |

The symptom makes me think it is not the display itself, but more likely to be a power supply or LCD driver problem. |
| Oldtestgear:
The display used in the HP 3488 switch unit does fit the 3478A. The only issue is one of the Ohms indicators (2 or 4 wire) is displayed as a marker rather than the correct symbol. It was possible to buy the 3488s very cheaply a while ago, especially without the modules. Been there, done that & rescued a 3478A from scrap. FWIW Phil |

The 3468A uses the same display as well, afaik? You might find a broken one with a good display. A 3478A is a much more worthy destination for the display anyway... |
