Hisense TV 40A5600F Dead - Wan't start

[sandrabrnelic]

When powered on LED goes red indicating standby.
After pressing the power button LED blinks 6 or 7 times, i don't know do i need to count last led blinking because it's faster then previous 6 and remain's lit and in standby again. Nothing is visible on the screen, backlight is off all the time. All caps on board are looking visualy OK. 12V is present. Anyone has service manual or schematic for this TV or any ideas what could 6 blinks code mean.

Main board is RSAG7.820.9867, power supply is on same board.

Update: I think backlight is dead because voltage on backlight connector rises to 140V and there is no light and no current through LED's

I was going to suggest testing the backlights. I had some Hisense do this same code and my problem was backlights. One went out. I use LED tester on mine and it reads as open if they don't light up on my tester. Plus, I've only had Hisense have bad backlights lol

On Hisense if you bet on backlights or capacitors, you'd win more than you'd lose
