Audio amplifier thermal protection
 

Can anyone please offer advice on this? The unit is a Genexxa
STAV-3150 Tuner Receiver belonging to a friend. The thermal protection
has always been too sensitive; then the sleep timer was accidentally
switched on whilst the speakers were being disconnected (my friend is
academically bright but sometimes manually inept). Now "the protection
circuit won't switch out".

Can the protection be reset? Has further damage occurred? He wants a
circuit diagram; I've tried Google, Yahoo, Jeeves, Alltheweb,
AltaVista:- no joy. Can anyone help?

in some units there are reset sequences you need to perform if it has a
digital system in it.
commonly you hold in one or 2 buttons on as you power up the unit to
reset it.
i would go to the websight and check that.
