Purchased this TV just over a year ago from Ebuyer. Got 1yr warranty from them & registered with Elonex for their 1 yr warranty. Sent it back to Ebuyer because HDMI input isn't working, but they say we need to deal with Elonex. I have emailed them but they don't reply. Has anyone else made this purchase, and how can I prove I registered with Elonex for their warranty. Any suggestions?
