I have a Hisense. 60DU6070 smart tv The power LED is blinking in a series of two. Then turning off. Then repeating.
Unfortunately, you're getting a lot of bad and not helpful information like replace capacitors, power supply ect without doing any testing to determine what the actual issue is. Where you need to start is by testing the main board to see if it's doing what it's supposed to do to "wake up" the power supply. Put your multimeter ground lead on the frame ground and find the terminal marked PS_On on the connector going from the power to main board (there will be a legond on the board to tell what pin is what) once you have your meter hooked to that connector turn the TV on and see if you see around 3.3 VDC, this is the signal that tells the power supply to turn on. If you don't see that voltage replace the main board if you see it you need to do some testing of the power board to see if its working, I'm going to have you run this test before going any farther.

I have a Hisense 55" that won't turn on.
Hi try to use a power module if you can (it's a risky situation "high voltage" or get a qualified personel) on the power issue turn it to 5 volts up to 7 volts while checking the functionality.

Hisense LTDN46V86US. Television won't turn on with the remote or buttons on the front of it and the red light is on in the bottom corner. What's wrong with it please?
Most likely you have a main board issue, this model set had a really high failure rate for the main board and for that reason finding one is not easy and if you find one plan on spending around ($100) on a replacement board. What gives issues is the EEPROM gets corrupt data stored in it and it doesn't send the boot sequence to the CPU to power the set up, without that information the set can't come on. You can order a new IC from shopjimmy.com for around $15.00 but installing it isn't something most can do as it takes advanced soldering skills as it's a SMD but if you have the equipment and are ok changing it it's a cheap fix...The part location is N10 if that helps. Good luck
