Hisense Roku 50R7E boot loop fix when reset button doesn't work. 

I did this myself without any knowledge, followed the steps. You saved me from buying a new TV, thank you sir

I have a 55R6040G Hisense Roku TV that had the LED Backlight go dim all of a sudden. The backlight was evenly lit so i suspected something on the main board was the issue. I scanned the board and saw the two capacitors in this video swollen. This happened last week and I'm waiting on the capacitors to arrive in a couple of days. But this video confirmed my suspicions were correct and was hoping this would be the fix. Your video definitely made me confident in knowing that was the issue. This video randomly popped up on my home page and I'm so grateful. Thank You for taking the time to post this repair. Cheers!

Haven’t done the repairs yet but you’ve already earned a subscription. It feels like I’m back in trade school. Awesome step by step procedure and well explained.

I am not electronically advanced but you just helped me fix my tv. I’m amazed. Thank you so much.

Thank you. You helped much more than customer service did.

Thanks for showing us that DMM (I missed your Agilent) but it's nice to rotate your measuring rig and also your welding rig when there's a chance, like in this case, I loved seeing you use the hoof tip or horse helmet (9:28) .. Thus we learn more (comparing). It's always good to have a beginner's curiosity (5:49) ... thank you so much for your time and sharing. I learned something -a lot- new today. An affectionate greeting from Mexico.

Thank you for this video!!!! This is exactly what my problem was, except that only one of the two capacitors was actually bad. Now I did not have the correct value on hand, so I ended up “creating” a 10uF, 350V+ (actually 550 volts) capacitor by putting a total of ELEVEN caps in series, all of varying capacitance values but all were rated at only 50 volts each. It worked perfectly!!! I am ordering the correct capacitors for this TV from Digikey, and I will replace both capacitors, but at least I have a working TV while I wait for them to arrive. Again, thank you, thank you, thank you for making this video!

This is exactly my problem. Really appreciate you showing what the device is actually doing! Most only tell and show when its off, not re-creating the problem. Thanks for the "Boot Loop" term, I couldn't think the best description to search.

Big dog I didn’t know what the hell I was doing but I followed the video 8 times and replaced the capacitors and it worked. Thanks because I couldn’t afford a new TV

Got me a soldering kit for $ 12 and 2 capacitors on eBay for $ 7. No more loop problem. You are the man, bro. This was much easier than I thought it was going to be !

Great video. After trying soft reset and hard reset on my 50RGE1 I found this video. Didn't bother checking just went a head and ordered the parts. After opening it up sure enough the 2 capacitors were bad and I replaced them. It only took a few minutes and fixed the problem right up.

You saved me a tv. Followed your instructions. Great video. Thank you.

Dude! You’re a life saver!! Thanks for this info. Hisense is of no help when you call, I tried the reset button numerous times with the same issue (screen bounces between on and off constantly), and sure enough.. have these swollen capacitors. Local computer repair place charged me $5 to replace them and now my TV works like new

Damn this actually fixed my TV. Couldn’t have asked for a better tutorial

Man! Thanks for saving me from buying a new tv!! I followed your directions to the T and only spent $4 on repair vs a new tv👊🏽👊🏽

Great video! Watched it once, was able to clearly understand the fix and replaced my capacitors in less than an hour! Thank you!

Thank You! I have this same model TV with the same problem. You saved me a big repair bill.

Thank you! Fixed mines watching you❣️

Having the same problem with a Hisense 55U6K from Best Buy. This is the model with the mini leds. The back of the TV shows May 17, 2023. Purchased on 10/5/2023. It failed in mid-December 2023 and was not used daily. Only now just getting around to trying to troubleshoot it. THANK YOU so much for making and posting this well-done video! 😎👍👍

Another nice fix. Thanks for the tips Big Dog!!!

Bro thank you so much you saved me from buying a new tv, this worked for my tv. Thank you

Thank you so much! I searched for months for an answer to this. I could not find 350v 10mf capacitors on ebay on Amazon that were reasonably priced or in the US, so I bought 400v 10mf and it worked just fine. I had a little trouble heating the old solder to remove and pushing in the new capacitors, but I kept at it.

My exact problem. I did the capacitors. My T.V. works now. Good how to video. 😊

I was also a victim of this problem with my Hisense Roku 43 inch TV. And guess what I saw when I opened the back cover? THE 2 SWOLLEN CAPACITORS!! So I replaced them and WALA! FIXED and RUNNING! Thank you my brother I have my 2 year old TV back.

Thank you so much. My husband and son wanted to throw our tv away, but I knew someone had a solution. I don't have the items I need to fix it, but maybe someone I know does so I can do it. Thanks again!

Greetings BigDogg, I’ve been away for awhile, now I’m back Thanks for the great knowledge as usual

Thanks, my parents where going to just buy a new one, i saw your video, bought 2 for 16$, got them then realized i got axles instead of radial, but they fit even though there 2x bigger lol and it works again

Awesome thanks! I believe this should fix my TV!

Good fix haven’t come across bad caps for ages

Thanks BigDog, this got me fixed up with a similar model, a 50R6E1.

Thank you for sharing! I went to eBay & ordered the capacitors for $8…my brother followed your tutorial and 20 mins later my tv is working again lol Thanks again much appreciation 🙏🏽 Oh and my brother said my old capacitors had burst like overheated batteries 😕

Thank you 🙏🏼 bigdogg for the perfect help I just replaced both of them they were both gone it works great now 😊

THANK YOUUUUUU, bruh. It didn't work at first after I changed the capacitors. Then i reset it. Still didn't work. About an hr later, it started working

Thank you for this video. You save me money.

I found you while Google why my TV keeps rebooting when I go into apps and now even when I watch roku it reboots. Ur 1st video showed me a reset button I'm hoping that works but if not hoping this video will help I love my hissense roku TV only 2yrs old. Now they don't have roku built in they have Google which I do not want lol fingers crossed I do not have 2 get a new t.v😅

Same issue with a 55R6090G5. Replaced with 400v's instead of 350v's and all is well. Thanks for the video.

Taking from a donor board😅. When I was working in the industry, we called it canabalizing! LOL. Nice Job! Well done👍

Thank you for great explanation. I just replaced a few Caps on my Commadore. Not as easy as it looks. I struggled on getting the iron hot enough. Me not the iron. Takes practice. Anyway thanks for the inspiration!

I did it!!!!! I fixed my grandkids tv!!!! Thank you !!!

Hey great video. I’m sure I have the same issue. My question is when you heated the capacitors to remove and put them in, what did you use? And what can I use if I don’t have the tool you have. Thanks.

EXCELLENT VIDEO!!!!

If you have an LG 4K 43", may have a backlight issue, turn the TV on, screen lights up - more around the edges, sort of dims, but looks like its on...my question has to do with when you turn it on, no incoming signal, should you hear white noise from the speakers? If the volume is (or has been) turned up, will it normally do that? Thanks bro!

Saved my Hisense TV by replacing two 10uF, 350V, 109 deg capacitors

Can I use the 50R6E motherboard as a replacement for the 50R7E since must of the ones I find are out of stock.

You're the man! your videos are awesome Just bought a cheap tv to practice, with the same issue. Started on mobiles when the guy tried to charge insane amounts, then said "or you could do it yourself" and started laughing back when Iphone 4 was released... So I fixed it with a baby blue screen and back. My friends were lining up for me to fix theirs with Baby blue, or baby pink, who laughed then :P Years added game consoles and now incorporating TV's, Thank you for your inspirational video. Any other tech avenues would be Boss? Also, awesome workshop.

Great detailed tutorial sir 👍🏽!!

Im having the same issue but i have the 2 mother boards in the back and my compositors seem to be fine can you think of anything else it might be?

Appreciate this video! Unfortunately my tv is doing the same as yours but worse. The backlights are not coming on at all, but if I shine a flashlight at the screen, the tv is behaving like yours. Last time I replaced my lights on another tv, I cracked the LCD, so not sure if I want to put myself through another light change

Thank you sir. Your method work for us as well…!!!

Do you do repairs? I have a black screen with a constant bootloop and dont trust myself to do it myself.

Great walkthrough! Subscribed 🤘🏽

An other great fix ! you're the boss man...very interesting, as always !

I have an element Roku e4sw5017rku and it's getting nothing but a backlight, ppl have told me it's the t-con board, is this accurate?

Hey BigDogg, I have a 70" Hisense that is doing this. The reset button didn't work so I took the back cover off and it's totally different than the one in the video and all the capacitors look good. What should I do now?

Thank you for this video sir!!!!! Can't wait to try this

Thank you for the information on this Hisense fault

Having trouble finding this 50r7e motherboard is the 50r6e motherhood compatible to use on this hisense model?

I tried the button and it did NOT work. I will NEVER buy Hisense ever again. Thanks for what you do and the information.

Thank you ...the Best video

Bigdog i know this is an old video already but figured id ask just in case. If you have the time i'd really appreciate it. The tv had been booting fine every now and again, but decided to do a factory reset (thinking corrupt firmware maybe) and it got stuck in the same bootup loop. Tried measuring at 200V level with a multimeter at the output of the LED connection, but it doesnt seem particularly obvious that its doing something weird. The voltage drops by maybe 10 V (from 160 to 150 at the white wire but from 80 to 30 at the red wire). However, the caps look fine. Should I just change them regardless even if they dont look bloated? I dont have a multimeter to check capacitance so dont know what else to check. Transistors dont look burnt, capacitors look healthy (as far as I can tell). Are there any other checks you'd suggest? I'm relatively familiar with electronic equipment testing but dont know what type of voltage I should expect on the backlight to make sense of it. Any sort of help would be a blessing

where is your shop. I've hisense TV 43 Inches horizontal lines dribbling..and sometimes won't light up. but there are heard..

where do i buy or order them? and how do i make sure they’re the right ones?

Ok you the man ..!!! Ok what if your capacitors are not swollen and the back lights don't come up at all ..??? Are there ballast that can go bad or can the led's blow also ..

I only found 400v 10mf capacitors. Will those work?

What is that you used to keep the capacitor in place

Great video!!! Good information

I got tv issue with pictures itself .led seems working.its seris 6 hisense tv.any suggestions what should i look for ?

Can I do thi for my 58 inch model 58RGE3?? IT WENT BLACK AND WONT START OR NOTHING?

I got the Hisense 65H10G, facing the issue. How do I fix it?

good day sir. i got a question. is it posible that this solution fix a similar problem but with an off backlight? (same boot loop)

Excellent video.

Thank you a lot man. It worked on my unit, however, it's not receiving signal from my remote.

How much do yo think this will cost to get replace for a 50inch Onn roku tv?

I came back here to say thanks, I fixed it

Zero voltage here on the red to backlight with tv on 150-190 on white.

Just watched your first video,and it didn't work as I tried 4 times. But, I noticed that a black bar came across my screen after I let the re set button go. Hopefully trying this will help. Thanks for you help

I have a Sharp LC-65Q7370U, it's doing the exact same thing. I tried using the reset button to no avail. I opened it up looking for a swollen capacitor, but all of the capacitors look find. If I purchased a main board and just swapped out the boards, do you think that would solve the problem?

Hey, Bigdog I wish I had found this video before I replaced the motherboard. Yes, I put in a Nee motherboard and the screen still does not come on. What could possibly be the problem now??

Good tutoring brother thanks

Does it work on Hisense vidaa too? My just boot once and shows nothing. Just light blue screen with sound. Is it a capacitor problem. How do i reset when my power button only turn ON but not Off my TV? Please help. I just described the problem im having.

How do I fix my hisesnse model 65r5e3 that will not power up but has adequate power source? I've tried everything I can find online to troubleshoot. Backlight is not working or flashing off and on. XD

Hi mate, I have a Hisense 32" Smart TV (Hisense 32P4). I watched your earlier video about the reset button. Unfortunately, my model does not have a reset button. I’ve watched this video and have had a look at the circuit. There seems to be only one capacitor for the backlight LEDs. Also, visually it seems to be fine - it’s not swollen or discoloured. I don’t have a multimeter that can test capacitors. Would you suggest I replace this single capacitor, or would you suspect something else is at play.

Thanks for the help

My tv have the same problem. So how much is to fix the tv

Another great vid. I have a Hisense with a similar problem. No visible reset on the panel. Is there another way to reset it? My symptoms are similar with a weak logo on power with no boot. All caps look good on visual inspection.

I have a 75 inch Roku Hense doing the same. Do I use a 10 far capacitor it well?

Same problem here, where do you buy the capacitors?

Hi, what make and model is your multimeter?

Im not this savy w/ the tech and im annoyed because my tv isnt old. Can i buy the parts & get someone to fix it?

My tv power button used to turn off my tv but the problem of display started it wouldn't turn off except I use remote. How do I do the reset?

I have the Roku 50R6+ it loops but then it goes to the main screen where i choose an app it plays for a few seconds then reboots again

After I replacer the capacitors it actually allowed me to reset the tv and put it in recovery mode but after I gave it an update it said was necessary it was in the boot loop again, please help!!

It worked thanks

Would 400v work?

Not bad & they are cheaper to replace than getting a board.

I cant tell if my capacitors have gone bad but im having the same exact problem so im gonna replace them and hope for the best

Awesome videos, but what if the capacitors are fine? Have you run i to that? Thats what im dealing with, they look good, no swelling or anything. Also, arent the capacitors dangerous to touch? How can you tell of theyre charged and how do you discharge them safely?

Do you repair TV’s in Chicago? Having the same problem with my sons tv

Can anyone share where I can purchase the exact Capacitor?

I'm having this issue with my 58r6e and replaced the 3 capacitors it had. Unfortunately it didnt change anything and I dint see anything noticeably damaged. Any advice?
