If it works I wouldn't bother it as there isn't much chance of that becoming an electrical problem. More likely it'll fall apart completely later and become unusable long before it'd be capable of a fire I'd wager.
FWIW X'EYEs are a huge PITA. The switch that detects the lid is cheap and the motors seem ready to fail (despite being identical to those in the SegaCD 2). Modding them for S-Video, overclock (10mhz is a sweet spot that works very well) and a region free BIOS are fairly easy due to being virtually identical to the Genesis 2. Extremely temperamental on the CD side of things sadly.
