Hi all,
to avoid more display "consumption" during long acquisitions, there is
an HPIB command to blank the display on the counter. I have asked to
KE5FX to add this feature in Timelab during the acquisition setup. Hope
he have time to do this.

Two possibilities: Cathode poisoning or bad tantalum caps. I'm not
sure if "cathode poisoning" is really the correct term for this
effect, but it's similar. There have been a number of tutorials out
there about rejuvenating VF displays.

It appears that the military parts system has the EL displays listed
for replacement purposes.

Should the display prove to be beyond recovery it might be possible
to buy a new one. Now, the cost may be another matter ...
These are made by Noritake-Itron. The generic part number is
CP3033A, but it does not show up in their product line on their web
site. It might be worth contacting them to see if there's any
possibility of still getting them.

Searching for Itron CP3033A turns up some parts brokers that claim to
have access to 251 of them.
