Hi,

First of all, sorry for mostly posting requests for support on this forum.

I've acquired a non-functioning Duo Monitor that I'm trying to fix.
When I've opened the device I've found that unfortunately someone else has already had a go at trying to fix it by replacing some electrolytic caps with ceramic caps - not a good sign.
I have noticed that the capacitor C528 is missing.
I have tried to find info on the capacitor value online, but to no avail (console5 has a list of the electrolytic capacitors on the device, but some of them are missing, like C528 - link (https://wiki.console5.com/wiki/PC_Engine_Duo_Monitor) )
There is a post on a repair webpage by "grogory" ( link (https://www.rep-arcade.com/2019/05/tuto-comment-ouvrir-un-nec-pc-duo-monitor-pi-lm1.html) ) where he has some pictures of the disassembly. In a couple of them you can see the capacitor itself, but the values are unclear to me.
Here are some pics with the C528 cap highlighted:

I can see that the rated voltage is 50V, but I am in doubt if the capacitance is either 2.2uF or 22uF.

If you have any idea for the value of that capacitor, please let me know.

Thanks in advance!

I looked around for you via reverse Google-image searching and found that iFixRetro also bought one and did a capacitor replacement job on it! He made posts on X/Facebook/Instagram, so here ya go. I already asked him for you but you should too.

This is a high res photo, but overhead so not much help in identifying cap values unfortunately:
