Sega Genesis 16-Bit.. Won't Power On / Show Picture

[Hitman Tyler]

Hi Everyone,
Can someone tell me whats wrong / how to fix :

The Story:

My sega genesis 16-bit would never power on / show picture.
I really didn't care until now, I would like you use this one as a back-up.
I plug the AC Adapter in the system into the wall and system. Hook the RF Adpater up to TV and System...
NO POWER & PICTURE.
So I bend the wire (AC Adapter) Now it powers on.. But... I still have NO Picture...
If I do not bend the wire (AC Adapter) there is no power.
I even opened the system and cleaned it.

So Please tell me whats wrong...

P.S. The Cables I am using says (If this helps):
Sega Auto RF Switch
Model # 1603A
The AC Adapter I am using
Sega
Model # 1602-1
Use With Sega Genesis

Also if need more info let me know.

Thanks,
HITMAN TYLER
