Originally the product was designed that if the speakers short, the unit automatically detects the error and then turns the relay on. Now, in order to improve the safety of the protective operation, once a short occurs, the product goes into standby mode instead of turning on and can only be powered on again by Main power-OFF and ON. 2. When the unit is connected to the Sony PlayStation3 with HDMI and plays an SACD, there is no audio output. 3. When more than 6 channels are connected in HDMI M-PCM, there is no indication of or audio output from the 7th and 8th CHs. 4. When the unit receives the command XDP:1 to switch over the XS DISP mode, with the XM ANTENNA unplugged, it can respond with XDP:2, the next number up. 5. The product may not respond to the following RS232C commands: EX/ES SUR:0A, THX THX:3THX:9, THX ON THX:2. 6. While playing back a DTS 96/24 signal, it transmits a status reply at an RS232C sampling rate of 48KHz SFQ:3 instead of 96KHz SFQ:5, which it should be. 7. When the product is connected to a Marantz LC3701 a Marantz PD4201 or a Panasonic PT-AX100 with HDMI, the onscreen image can be tinged with pink. Solution: 1. The MAIN and HDMI microprocessors need to be updated.
