Epoch Fight of the Titans REPAIR

[Aurelio]

Hello, my name is Aurelio and I am new to the forum. I have been collecting video games for over 20 years and for the last 4-5 years I have been very interested in LCD and VFD games and tabletops. I recently bought a tabletop from Epoch. It's Fight of the Titans. Unfortunately this is defective and I think the problem comes from a defective electronic part on the board. In my opinion, the previous owner has already soldered around. My question now is, does anyone have a list of all the electronics parts that have been fitted here. I once made a list with the parts that are now installed. I don't know the value of the Zener diodes. Before I re-solder parts, I wanted to know whether the right parts are in there. Thank you
I want to insert photos, can anyone explain me how to do? Thanks and best regards
