The CPU appears to be fried unfortunately, it looks brown right in the middle of the package (around the die).
Upon turning on the console, all I get is a black screen, no TMSS (if it has it, I'm inexperienced with Sega hardware) nor does the game start. As for sound, I get the usual noisy output and pops whenever you turn on/off the console.
I am a trial member still so if anybody can help me to point in the right direction on what to do or which CPU to get (if it is the CPU), please contact me over PM.
(waiting for exams to finish so I can continue working on that mod from like 2013 :V)
If you do need better quality images, I can provide, it's just that I have taken these at night a few days ago without much thought put into it. Also, I did try Sega-16 but my account never got approved.
