hi,

bought my c716 in feb this year.  Running great. but in July, suddenly no video.  difficult to get to their service team. I tried method found in web resetting the tv.

Ok for a day and happen again.  when i powered on, it will load android, and few second later no video. the 4 amber leds light on.

when finally got to their service, they gave me firmware file.  so i done the update and it was running well until last week (4 months later).

now it happen again, and their service just unrsponsive….
