KD55X8509C Keeps Resetting Itself

[edcoomber]

Hi, I've just taken delivery of a KD55X8509C and it's reset itself three times in the last hour.

It has the latest firmware installed, it'll work for about 10 mins then turn itself off and the led will flash red three times in succession.

Is there anything I can do to fix it, or do I need to return it?

Hi, thanks for your replies.

Would they not bring a spare motherboard out with them? When I had a faulty Samsung tv a few years ago they replaced the panel in my living room rather than taking it away with them.
