Thank you very much. My 50" Hisense H50B7100 had the same exact problem, so I tossed the coin and took the chance. The most difficult part was removing the white back light reflector, I had to use an hairdryer to let it loose, but it was quite a mess... Anyway, the work needed a lot of patience and care, but now my TV is back on 😊 on the kitchen wall. Changed all four led stripes with pullovers from a damaged donor TV, that's all I could find here. It's been only 30€, repair shop asked 180€ which was not worth it against the 300€ I paid the TV. Thank you again.

[@roderickho4281]

That’s great to hear. I’m glad you gave it a go yourself and managed to fix your TV!

[@warclan5429]

No TV should have a lifetime of 3 years or less. My sharp lcd TV has 20 years no issue. Even if you repair it. The LEDs will last 3 years. Or capacitors will dry up. Basically bad design with 3rd level components.

[@ceoa]

I'll NEVER buy a Hisense again. 🤨 This must happen often for so many videos to be made about the same problem. My TV's not even 3 years old!

[@roderickho4281]

Not always the same problem, sometimes it’s capacitor issues. Sometimes main board goes bad. If you still have a Hisense tv, I think not using 100 brightness in settings would extend the tv life

[@ericaneomia8709]

Same. I bought 2 on sale 2 years ago. One for my room and one for my living room. The one in my room randomly stopped working and it’s annoying looking at all of these videos . Never again 🤦🏾‍♀️

[@MohammedAneek]

Good video. So here's what I did: 1. Had LED blink issue, no display 2. Tried taping part of the right side ribbon. TV got on and sound worked fine but no display. Tried taping different parts on right side ribbon, same result = no display but TV works (sound on menu etc) 3. Then tried taping left side ribbon (left part of display main cable), no display again. Eventually when taping different pins, display finally worked. There's a dim horizontal dark grey lines which is not visible from 5 feet apart. So I think this is the only possible solution to get the TV to work somehow. In my country it's almost impossible to repair or have to pay a hefty price. TLDR: Try taping the ribbon cable pins on both side (left ribbon and right ribbon too) 4-5 pins at a time. Eventually display works. This is for all those guys who say they fixed the blinking issue, but no display. This could work. Worked for me.

[@roderickho4281]

Thanks for sharing this!

[@FounderOf4]

I'm researching all of the possible issues with my Hisense 65H6570F, not seeing any puffed caps, discoloration around any parts or on the board. So I found this video and your comment.. so you literally took electrical tape and applied to the ribbon cables until it was operating normal?

[@MohammedAneek]

@@FounderOf4Yes, but the catch is that you will see black faint lines horizontally. You could see those lines from a feet or 2 in front easily, but the screen will look normal from 5 feet away since the lines are more like transparent black lines. Apparently covering those pins will block horizontal display lines, so I guess the specific led which is causing the issue (current short probably), is ignored so the system runs fine without the error detection.

[@FounderOf4]

@@MohammedAneek thank you for the reply. My wife was not wanting to wait for a fix, so we bought another TV. I'm going to fix this one for my hobby room. Faint gray or black lines are mot a problem for me! Thanks again!!

[@michaelhitz7312]

Great video sir, someone set their 55 inch tv out to the trash, i took it and replaced an led strip via your video. This was a banger of tutroial.

[@roderickho4281]

Amazing to hear you’ve saved a tv from being trashed!

[@user-vo9qf9mx8u]

Thank you so much, my wife found out about my affair and trashed my TV, luckily your video helped me to repair it!

[@d.l7198]

The les replacement was the most important part

[@roderickho4281]

Yes this was missed in this video. Check out the LG videos with part 1 and part 2. This shows replacing the LEDs

[@WONDAWOMAAAN]

Is this a joke?! I am not putting myself down when I say…This is waaaaay to much for a tone thats trying to express how “easy peezy” this is. This is high level repair sir. 🙄

[@roderickho4281]

This is definitely a high level repair however I couldn’t find any tutorials when starting out so I’ve finally decided to record the process. Following the steps is at your own risk and not easy peezy!

No worries, it is a long and tough repair and very easy to break the Tv in doing so!

[@theonewhoknows1741]

The light you replaced is too bright

[@Mayorr1]

Thanks. Watched your video, disassembled my h55b7100. It was last led busted (you have to get plastic lens off to test last led on strip because there is no pin on pcb for last one). Now I've ordered all replacement strips from ali for 10$. Thanks.

[@kuttybangbang]

How much is a repair for something like this I have 2 tvs that have this issue

[@RichardNavarrete1]

Thanks for this video. How did you know it wasn't a blown power board? Another video said if the power button started blinking, it was the power board. Mine blinks. Model: 43R6090G5 Thanks!

[@roderickho4281]

There’s potential it could be the power board too but from experience with Hisense TVs it is 90% an issue with the LEDs most of the time

[@RichardNavarrete1]

@@roderickho4281 Good to know... I'll test them soon. Thanks!

[@brenex-ym2id]

Very unfortunate to not record the replacement of the LED light, kinda the whole point.

Can someone tell me what that electronic tool is called that he uses to see if there is anything faulty in the tv? It measures the volts...also thanks for the video you helped me figure out a few things wrong with my tv 👍👍

It’s a multimeter

[@lucanapolitano3587]

I have exact same tv it seems. My tv just flickerd and shut down all of a sudden as i was on the ps5 . Wont start back and does the same red light blink. I was hoping it was a board. Is there any soldering involved to replace the led strip?

[@roderickho4281]

Easier to just replace the entire led strip

[@EricBouchardMarketing]

I tested all the led backlights and I found one that doesn't work anymore, but if I saw that some led lights is is more weak than others, do you suggest to replace them all ? And do I have to replace all the stripe or just the light ? Thanks !

[@roderickho4281]

Next steps I would check continuity between the power supply cable to the led strips and if still don’t turn on I reckon faulty power supply

[@roderickho4281]

Replace the whole set of strips for uniform lighting and also you don’t want to be stripping it all down again to change a strip again in the future

[@hugostengard-green3250]

Silly question but where can I find big plastic sheets like the one you used to remove the screen?

[@roderickho4281]

I got this from dismantling a bigger TV. It’s a light diffusing sheet that sits behind the screen

[@Elvis-dw7ux]

Tried everything for Samsung LN26B360C5DXZC...no luck...the standby light flickering when I press the remote or TV buttons but NO picture at all. Got a new Rogers Netbox today but still no luck...cheers from Canada....

[@roderickho4281]

It sounds like it’s struggling to turn on. I’d recommend searching your tv model number followed by power supply repair kit or even see if replacement main board and power supply board is worth replacing

[@GalaxyCat001]

Good video, with the problem that this TV had, would there still be sound if it was connected to an antenna etc? Or does a bad diode also prevent sound?

[@roderickho4281]

Thank you, no there won’t be any sound. The bad diode prevents the Tv starting up at all so none of the TV’s functions are available.

[@tmho7091]

Is this only apply to this Hisense tv? I heard that other tv with backlight problem making no picture shown on the screen will have sound. Have you heard of this?@@roderickho4281

[@user-gf7vv8wk3h]

Nice

[@Unique77783]

This is a bit much for me personally. My will flash on with the blinking red light and i see the tv name come up and then it turns rt off with a flash of a line and the red light blinks

[@roderickho4281]

At a guess, I would think possibly an issue with the power supply or the main board is faulty

[@CozzaP1969]

My Samsung 50" QLED TV is doing the same thing.. it won't turn on. The screen goes blue momentarily and then back to black and the standby light keeps flickering on and off. I'm guessing it could be the same issue. I have replaced the TV with a Hisense, but would like to try and repair the Samsung or at least sell it for parts. I'm guessing it would be a similar repair although obviously the parts will look different inside.

[@mommyririadventures3938]

How do I take the old led lights off

[@GilinSC]

The flashing light tells you what is the problem. I fixed TVs but Sky Worth is a pain in the A**! I have a non-flashing ed light. I reset it and the remote with no luck/ success. Any suggestions? I love your accent. Australian?

[@roderickho4281]

I’ve not come across Sky Worth before. What is the model number of the TV? It’s a British accent, I’m from the UK

[@martigustamante1230]

Where can I order LED strips for my TV ? It’s the same issue as that one.

[@roderickho4281]

If you google the part number after dismantling the tv the most convenient option to buy should be near the top search hit

[@playstationreloaded4046]

Keep it up dude!

[@user-ev5gc2ew2w]

Mine is like this but no blinking red light. Tried everything

[@Vindictus747]

My issue is that the LED's are super dim. I pulled my TV apart and I see at least 3 on the bottom strip that don't light up. But all 3 strips are super dim

[@roderickho4281]

Best to replace all the strips for peace of mind

[@TheSteyrguy]

mine was working and then i heard a fizzle and now my tv is doing this exact thing with the red light, would that suggest it being the same issue? same model tv btw

[@roderickho4281]

It seems quite likely especially with the fizzle sound

[@TommyDominguez-kh6ce]

It flash 10 times and a phus and start again

[@tajindersingh6998]

Hi, my Tv wont turn on. When i try turning thr tv on, the red light flashes for five times then the light is solid. Any suggestions on what i can try to repair my tv?

[@roderickho4281]

I’ve never checked what the number of flashes correspond to but being a Hisense tv more than likely an LED along the backlights have gone bad

[@Knappinsc]

I have the same issue with my hisence andriid 65". Do you need an entire led strip or just one led from the donor?

[@roderickho4281]

It would be simpler to change the entire led strip

My tv keeps turning on says Hisense Android and shuts off. Then will try to start up and power's off. Can't put the firmware on it because it doesn't stay on. I bought the circuit board kit and changed all the boards and it still does the same thing.

[@roderickho4281]

That’s strange with everything changed. When it’s turning on, take a video of the screen in a dark room. See if there are any dimmer dark patches on the screen. This could indicate the LED chips being burnt out

You need to take the tv apart before knowing what the part number for the led strips are

Can you use a LG tv backlight to replace the Hisense tv backlight with, will this work

No they are different backlights

Hey so I got a big hisense tv that when I got it I have no information about it and I had no remote or power cable. If I had to guess its a 65 or 70 inch tv. I bought a power cables and remote for it off of amazon and now the red standby light is on and when I press the power button the splash screen will come on for a few seconds then the standby light will flash a few times and the tv will turn off. I'm wondering if anyone might be able to help diagnose the problem and suggest a solution.

[@roderickho4281]

Record it starting in a pitch black room to see if there is a dark spot. That would indicate a blown led along an led strip

[@jaredh2341]

@@roderickho4281 Thanks for the reply, when I attempt to turn the tv on in a dark room it looks like the right side of the screen is definitely darker than the left side. As if only 1/2 of backlights are being lit.

I think this would suggest an issue with the backlights but so bad just yet that the tv is completely unable to start yet

When you test the lights to see if they light up . Is the power on or does the multimeter doing the powering for the each led light

Power is off from the mains. The multimeter injects a little bit of current through the led to light it up

... and this is why the first thing you do when you buy a new LED back lit set is to turn the LEDs down as far as you can tolerate!

Yes that would definitely prolong the life of the Tv. However, a bright screen is also more enjoyable!

[@adrianhernandez7197]

Same TV, same problem; I'm having a tough time believen it is a faulty LED, considering you did not show nor the faulr or the replacement itself. Hisense ppl say the 2 blink code indicates a board issue, but OC, thats the default answer from their side. However, since you didnt show the process as a whole, can't agree on its legitimacy.

[@roderickho4281]

It was LEDs however that section wasn’t recorded very well. Feel free to try changing the main board if you want to, all TVs develop different faults

[@MrBandwagon24]

I don’t know if you’re trying to help us or just want to show your expertise, this isn’t worth to do for a cheap TV like hisense, but I guess the word cheap means disposable. Nice work anyway. Mine is not even 2 years
