PROTECTOR/CHECK CODE 21 COMES ON ONCE A WEEK OR SO.
STR-DA2000ES, STR-DA3000ES and STR-DA5000ES:
Doument Reference: E23914196
Subject/Description: "Protect 21" is displayed when connecting to speaker/powered subwoofer combo
Protect 21 is displayed when
connecting to speaker/powered subwoofer combination model such as the
SA-VA7000ED. The problem was also found to occur when connected to the
Definitive Technology POWER MONITOR 500 and POWER MONITOR 700 series
The DC detection circuit is triggered when the speakers are connected.
Add a 4.7k metal oxide film resistor across capacitors C1319 and C1329 located on the D-AMP board.
Hope this helps. =)
