A repeat of a few tips.
1) Service menu: In standby mode press, INFO, MENU, MUTE, POWER. If you must play then IMHO don't rely on your ability to memorise settings but take pictures of all the settings before "adjusting".
2) Digital signal information: Press INFO for 10 secs.
3) Internal Diagnosis and report: Press RETURN for 10 secs.
4)System reset: Press EXIT for 10 secs
