Im 25+ years an Audio Visual Installer and general fault finder (I also own the company ) . That does not mean I know everything, But it does mean I get daily faults to find, Some are common faults but many are still faults for the first time......You must be open minded about this.
Mad MR H, in your 25+ years have you ever seen a unit power up by itself? I was sitting in my recliner, hadn't powered up the cd player yet but rest of system was on. Then I actually saw the unit power up, I did not touch the remote or anything else.
About 2 weeks before I had placed a cd in the tray. Decided to go to washroom first before pressing play. While in the washroom the music started playing, WTF as I live alone.
