RE: Technics SL-PJ27 CD player Help needed please?

Our Technics SL-PJ27 CD player hasn't worked since the new son-in-law fiddled with it, previously in perfect working order. The screen lights up and when you press play, it shows Track 1 but then the CD ejects itself. We close the CD drawer put still nothing. We have tried with numerous CD's to no avail. We are not tech-heads so just wanting some direction as to what the problem could be, please. The son-in-law has not been able to fix it and just says it's old and we need to update.
Possibly, he has pressed something we have never known about.
