Cannot boot any games - Pictures included

I am attempting to repair a sega genesis model 1 [Not High DEF]. The issue is basically when i put the game in the Sega Enterprises logo shows up basically showing that it sees a game but doesn't boot up the game after and goes into a black screen. I have tried different games and such but nothing seems to be working. If anyone can help me figure out the problem whether it needs a new cap or something that would be great.

If more pictures are needed i will be happy to take more in a response upon request. Thank you for your time.
