All sounds like a clear case of 'send him another' dosent it.
They have got me to restart it, reset it to factory settings, said it is my HDMI cable at fault despite the fact I was not using a HDMI cable when the problem first occured.
All this was via very slow replies to Email to the support Email address. They then stopped replying to my Emails and even when I sent an Email requesting a read receipt I got nothing back
So I phoned the helpdesk today(normal wait for ages with annoying messages interrupting the overly loud Xmas music), they got me to unplug all devices except the power and composite connection and the problem is still there.
Now you would think it is a clear case of 'send him another'.
NO, it now has to be sent to the manager for his consideration and he may not get back to me before Christmas as he is rather busy at the moment.
