I'm in the UK and have recently bought a Pioneer VSX-923. I'm not sure if this model is available in the US?
I've been having a few problems with it and have posted about these on our AVforums. I've received a reply from someone who has told me that Pioneer amps have lots of issues and told me to head over here and I'd probably find alot of information.
I guess I'm just after finding out if anyone has any of these problems, or similar?
1. I've noticed that the amp speaker display light array 'freezes' occasionally when using any of the standard surround modes. Normally, with 5.1 the six lights are lit to show a 5.1 signal being received. The LFE channel light also has the little '(( ))' indicators. Then when a stereo source is input the display will just show left and right speakers to indicate a stereo source. However, I'm finding the amp sometimes gets stuck with 5.1 speaker indicator lights lit and the LFE indicator lights not flashing. This happens mainly with Sky digital TV with sound via co-ax. The problem also happened on another input...my WDTV Live Hub via HDMI. I was watching a 5.1 Dolby Digital .mkv file. The speaker indicator lights were lit (FL/FR/CTR/SURR L/SURR R/LFE). For no apparent reason, the LFE indicator froze and was permanently on, regardless of whether an LFE signal was present. When pausing playback on say, Sky or the WDTV (and thus no audio present), the speaker indicators will stay lit whereas normally they will all go out when no audio is present. Also, when this happens with Sky digital TV, the 5.1 lights stay lit even when Sky switches to a stereo input signal. Normally, the speaker indicator lights will just show the L and R lights lit.
It could be easy to assume the display is fine unless you notice that the LFE indicator has frozen.
2. Many Sky digital TV broadcasts have DD 5.1 that have commercial breaks in stereo or intros in stereo that then switch to DD 5.1. When these broadcasts automatically switch to DD 5.1 from stereo or vice versa, my amp makes a loud 'pop' from the speakers. This only happens with NeoX selected. Any other setting is fine. I like NeoX as it seems the best at utilising my front-wide speakers.
3. When I select INTERNET RADIO using the 'NET' button, it will play the station already selected. However, when I press either the up or down arrow buttons to scroll through stations it often won't scroll. This also happens with the 'favourites' option in that it'll play the last selected station but won't let me scroll through the saved stations.
I'm just wondering if any of you guys over there have had any similar issues?
Thanks in advance for any help you can give me.
