Hi, I'm having a random issue with my q930b soundbar. I've only had it a couple of weeks. The issue is randomly it will lose all functionality - remote doesn't work, nothing on the display, and I have to remove the power plug for 10 seconds and reinsert to get it working again.

I'm using the HDMI port in the soundbar connected to a HDMI switch, (running an Amazon cube, TiVo and BD), and the TV/arc port is connected to my TV port. When it's working it's really good but this issue is very annoying. Is there anything I can try to fix this please?

Thanks
