These Hisense H8G series (or Q8G if you are in Canada) tv appears to have a common failure of the main board. Many posts on Reddit without a solution. Mine is a 55" tv hence the 55H8G model (TV comes in 50, 55, 65 and 75". Corresponding models are 50H8G, 55H8G, 65H8G and 75H8G). Symptom is that the tv will not turn on, only a slow blinking white LED near the on button on the tv. Has anyone found a repair for the main board? I can buy a replacement main board, but would prefer to repair my main board. Thanks.
