Hisense 75 inch ROKU TV, red light flashes but screen is still black; Full Repair!

Hisense models 75r6e3, 75r7070e2, etc. This 75 inch ROKU model will power on, the red light at the bottom flashes, but we have a totally black screen. In some cases you can see a very dim picture. If you hit a button on the remote you can probably still hear the clicking sound through the TV. So if your TV is on an Input you will have sound but no picture.
So what is happening in 99% of the case is these 75 inch hisense TV's need backlight replacements. How to tell for sure is if you put a flashlight up to the screen you can see the Home Screen or a picture.
This is a step by step TV repair tutorial on how to replace the backlight's on this model which is the Hisense 75R7070E2 model.

We had our Hisense TV for under 2 years when the backlight went out. After watching your video, I have the confidence to fix our 75R6E3 Hisense 75" TV. I ordered the parts (14 LED strips) and tools needed which all came in and I plan to do it this Saturday. Thank you for the great instructional video @BigDog8882...I'll post again after I finish on Saturday..fingers crossed!

All the videos I’ve seen about how to fix this… have inspired me to get a new one.

By backlight went out on my tv and I bought a new one thinking I’d have to go to a repair show for the old tv. But found out what the issue was because of your videos, going to attempt to repair the tv next week. Thanks again!

Damn, u don't miss. Kept telling myself no way it's faulty backlight. Replaced main board twice, replaced power supply. Turns out I wasn't shining my flashlight in the middle where the Roku shows up when TV powers on.

I can't believe I watched and UNDERSTOOD that entire video! Great instruction technique. Thank you.

I have the exact tv with exact issues. Wow! I followed every step and own TV. First time attempted

Hello sir. Just wanted to comment on how informative this video was. Unfortunately it was a fail for me because i cracked the screen on my 75”. Too big for one man. Note to everyone. Use two maybe four ppl for this job. Keep up the good work. And thank you.

[TallyTechandTroubleshooting]

Much appreciation and respect for this repair! Fantastic job, Big Dog!! You ARE the man!! God bless...

Hey BigDog, I used this video to fix my 75h6570G, went ahead and just replaced all LED strips instead of replacing a single LED like you did, but wanted to say thank you for making this video you are amazing

[gemzentaurus]

Would jumping the individual defective LED with a blob of solder work on this model?

[josephperez]

Hi BigDog nice to see you in action again and share your great wisdom.

[domenic]

You sir are a master, thank you for putting out videos like this. I have enjoyed watching your videos and when I have watched them all I may order your repair course.

I´m never buying an Hisense tv ever again.

[joelgillooly]

You have a lot of patience! Surprised you didn't swap out the strip but went to board level repair. Most of us don't have the equipment.

[wise_professor_beats]

Great tutorial🫡 Can you show me where to buy a screen replacement for that TV??

[whizzo]

Looks like BD is gonna need a bigger work shop for these bigger TV's along with a helper. lol At 72 yrs old a 65" is as big as I want to go and that is a chore for me. Give me a 55" all day long. We will see. Love your channel!

[SagittariusWoman]

Can I just buy the entire strip and replace it? I’m not trying the whole soldering thing. My eyesight won’t allow it and I don’t know how.

[pedrobalbuena]

Okay bro my first time i attempt this repair and it worked! 75 inch hisense but different model than yours. Only one question I completely destroyed the white backlight white sheet thats glued with the led strips. Is there anywhere i can buy this?

[ralters]

My tv had the exact symptoms you described and I took it apart and put the meter on the terminals as you did and I got no voltage and no lights lit up. I did it plugged in of course.

What replacement LEDs do you use to replace individual LEDs?
