I purchased a used Crystalio II VPS3300 on ebay that was listed to be fully functional. After a two week shipping time, it arrived and had a several issues.
First issue was no audio over HDMI. After looking deep within the settings, it seems that by default, HDMI is set to "Force DVI" which means audio was getting removed. Changing the settings from "Force DVI" to "Auto" fixed this issue. However, there are still popping sounds sometimes with the audio.
Second issue was that the unit powered off and would not re-power back on. It was not in standby mode and the power cord was plugged in. The manufacture recommend I unplug power cord from unit for one hour and replug it back in. This fixed that issue (for now).
Third issue is that unit will sometimes will no longer output any image at all (seems to happen like 10 to 30 minutes of use). The only way to fix this issue seems to be to put unit into stand by mode and then turn back on.
Now the forth issue is the major one. On sources like PlayStation 3 and Xbox 360 the VPS3300 will display the source image and then loose the source image (screen goes black) and then source image returns quickly, but then again screen goes black over and over. While this is happening, the VPS3300 keeps saying "No Source" and the input resolution. In most cases I have the sources set to output 720p over HDMI and the VPS3300 to upscale to 1080p59.94 over HDMI. The odd thing is that some screens and games have the problem while others do not.
For issue #4 the seller is saying this is normal and is due "the signitures from the HDMI devices". Now I call shenanigans on this as I have owned other video processors like DVDO Edge and Optoma HD3000 and I have never encountered this issue. I really need help here from other Crystalio II VPS3300 owners to know if you have ever encountered any of these four issues and if so are they part of the "normal" function of a VPS3300 (or a defective unit) and how to troubleshoot/fix these issues. Like I said, issue #1 and #2 seems to be okay at the moment, it is just issue #3 and #4 I have trouble with at this time.
