Hi

I purchased a MB micro last year from WOS. It had a few issues at the start with a black screen but i thought nothing of it. Now the HDMI port comes up no signal sometimes on a reboot and the screen will go purple. I have tried various cables, tvs and it will work for half an hour or so then itll freeze and on reboot it will say no signal. I have reflashed with just the basic openvix latest and tried older images too and the same thing happens. I have read this could be a faulty CPU as this will usually effect the HDMI port. Anyone know how i go about getting this replaced as it says the MB come with 2 year warranty from WOS?

Thanks
