Thanks for the reply, it's just over two years old so may cost more to repair than it's worth? Screen keeps glowing very bright, then dims to green, then comes on as normal but with flickering. Very odd?
It's never too late to send away to Samsung. They are often very helpful and might just tell you how much it might cost to fix it outside warranty. You don't have to pay to fix it at the end but its worth knowing what the problem is. Thanks
