If you plan on keeping it it might be worth adding a heat sink to the CPU - 7501R1
If there is any heat sink paste under the large TED heat sink then replace that with fresh, may of dried out by now and won't be doing anything. Your Plus/4 will have paste on the TED, (found under the metal shielding in a +4).
The most common fault of all the 264 series are the TED or CPU chips frying. As with your C116, if you saw a black screen the CPU is normally dead, if you saw random characters the TED is about to die. If you did see random characters on the screen then do not switch it on until you have replaced the TED as it can take the CPU out at the very same time when the TED dies, not always the case but both chips can die at the same time...
If you have joystick adapters, keep away from auto fire and any stick with flashy lights as the ports are not shielded. Only use basic joysticks like the Zip Stick, Competition Pro, Cheetah ect types.
Do not use Sega Megadrive pads on the 264 series as these can permanently damage the TED chip, joysticks may start printing random characters on screen, (other than what they should be printing) via Basic. This still continues when playing machine code games as it interrupts with what your doing with the joystick.
