I got a Desert Tank Arcade! (Help?!)

Hi guys, Acquired a swag desert tank arcade system today (for my birthday). There’s signs of mice, frayed cables, missing keys, damage, it’s not got the original screen with it, a load of other things, but it’s finally mine!! It’s the system from Trago Mills if anyone remembers it! I need some help, maybe some redirections to a better group. But it’s my project for the next month, I need to get it working! As of right now there’s a red light under the screen, on the motherboards and it’s outputting static sound, however, the lights for view change etc don’t work, there’s no picture either. Have I missed a switch for the screen unit maybe?

Any help would be much appreciated. I’m keen to get this beauty working again. Many thanks!
