Why won't my television power on
My Hisensense 5020DUS blacked out botht sound and picture without warning. When attempting to power the unit on by either the remote or power button. the red indicator light blinks 6 times and the blinking light disappears and the screen remains dark with no sound.
ANSWERS:
@circle77 Hisense is still an off-brand and there are no error codes. A Flashing red indicates that there is a possible short in your TV. The first possibility is a bad Power Board or a bad LED (backlight array?)Start by taking off the back cover and inspect the boards. Check for any obvious damage. Post some good pictures of the individual boards as well as how they interconnect, with your question. Use this guideAdding images to an existing question for that. You will need to have access to a multimeter just so we can have you check some things once we can see more.
Yes so after a few days of waiting for wrong parts to get here since I called hisense support they said it was the main or power board…bought both then replaced them still had the blinking light and tv wouldn't come on… so grabbed some 9v batteries and went through testing the led strip lights there was a bad one… haven't ordered the strips to fix correctly yet but I did cut the led node off and Sauder a blob where it was to resume connection for all other led lights and it worked… so put the whole TV back together and it works perfectly can't even tell there is a light out but will still be ordering replacement strip. Hope this helps!!! My email is if further questions are needed!

Im not sure whether this is the issue, see this fix for hisense tv not power on : https://youtu.be/g4G3ocxkDlk
You can generally reset your television for such sort of issues. Nonetheless, most presumably that won't work for your case as you expressed that the LED squinted like multiple times. The issue is I was unable to discover numerous assets on the web for Hisense TV mistake codes. I discovered one where it is composed that the LED flickering multiple times implies breaking down mainboard or inverter. Also, for the great case, just breaking down LED. You can check the topspraymop found on the off chance that you need more data.
