What happened to DSCOVR, what stopped working?

Question

In Scott Manley's recent video Views Of Earth and the Seasons From A Million Miles Away - DSCOVR & EPIC after about 04:20 he says:

…it’s one of my favorite missions because it has this very simple idea of just showing the Earth continuously. So you could browse to a web page and always see what it was, until June (2019) when it stopped working; we haven’t had any updates since then.

Question: What stopped working, the EPIC camera or the whole DSCOVR payload or the whole satellite, bus and all? There are a lot of instruments on DSCOVR, including some that provide early warning of major solar events that could disrupt Earth satellites and power distribution.

EPIC pictures started being mad available again on the 12th February, with daily pictures resuming on the 20th — , Mar 02 '20 at 15:06
@JCRM Thanks! That could also potentially be a helpful edit to the current answer or a new answer. — uhoh, Mar 02 '20 at 15:09
it's a pointer that there might be more information available, but doesn't, in itself, add any useful information. — , Mar 02 '20 at 15:20

On June 27th, 2019 NASA states that DSCOVR is in a "safe-hold".

All DSCOVR space weather instrument data and other instrument data have been suspended as the spacecraft has entered into safe-hold. Anomaly investigations and associated recovery activities are underway.

A few days later they said it had to do with the satellite's position.

“NOAA is addressing a performance issue with the DSCOVR satellite,” John Leslie, a spokesperson for NOAA, told Popular Science in a statement. “Engineers have placed the satellite into a ‘safehold’ position, while they first diagnose and then work to fix a technical issue in the system that maintains the satellite’s position.”

According to Simon Carn, the September DSCOVR Science Team meeting reports...

they hope to restore EPIC by January 2020. Need to implement star-tracking software to replace faulty gyro, so the S/C can orient itself & point accurately at Earth.

@OrganicMarble I can't find any more information. – Schwern Sep 30 '19 at 17:34

@bitchaser Thanks, I found a better source. Still a mystery. – Schwern Sep 30 '19 at 19:13

based on this comment above I searched "DSCOVR gyro" and found this item which includes a link to this tweet. If you like you can update your answer with these. – uhoh Oct 01 '19 at 03:05

@uhoh Done, thanks. – Schwern Oct 01 '19 at 17:00
looks great, thanks! – uhoh Oct 01 '19 at 17:45
Another "source" but less information and not much greater credibility - https://spacenews.com/software-fix-planned-to-restore-dscovr/ – Oct 09 '19 at 07:20

I think there has been some more recent news: Wikipedia says DSCOVR came out of the safe hold on March 2, 2020, and resumed normal operations and links to Space News' DSCOVR back in operation yay! – uhoh Mar 10 '20 at 23:32
That's a really bad wikipedia entry :( – Mar 11 '20 at 09:01
