Voltage Display Replacement (DSN-DVM-368) on Zero Zone LPS-25?

Hi All,

I bought my Linear Power Supply secondhand. I opened it up and if the name on the board is indicative of the maker, it looks like it's a Zero Zone LPS-25. The voltage display has been dying for some time and I would like to replace it but I'm having some difficulty finding it. Anyone have one of these? DSN-DVN-368 v3.01.

I am definitely a novice when it comes this stuff, but my soldering skills are pretty decent. I used to mess around with R/C cars and I've built a couple ACAs, although I don't really comprehend everything I am doing since it's basically like a paint by number type of build).

At some point, I would like to learn enough to build one of these Linear Power Supplies myself and this display replacement is a start right? Any help is appreciated. Thank you!
* Alos, any tips of removing what looks to be hot glue?
