Hisense Roku 50R7E boot loop fix when reset button doesn't work.
HTML-код
- Опубликовано: 31 май 2024
- This Hisense led TV model 50R7E keeps turning on and off and never gets past the "Hisense - Roku TV" Logo. If the reset button on the back of the TV does not work, replace the backlight filter capacitors on the circuit board. They are usually swollen and are not supplying enough voltage to the backlight strips, therefore preventing the board from keeping the television ON and TV goes into a boot loop.

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.
I did this myself without any knowledge, followed the steps. You saved me from buying a new TV, thank you sir
Where did you get the capacitors? Part number?
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.
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 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!
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 !
What size of capacitor?
Damn this actually fixed my TV. Couldn’t have asked for a better tutorial
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! 😎👍👍
I pulled the cover off and all the caps look good. I have no idea now what could be wrong with it. :-(
Its still under warranty, take it back or call Best Buy with model and serial #.
@@frankcanha You say they "look" good. Did you test them to be sure? I've had too many times of buying something and relying on the fact that it's new, and turn around and test it and it's garbage. This seems to happen more often than it should these days. Anyway, if you decide to test them bitches, there IS a right way and a wrong way. From what I gather, (yeah, I ain't got a clue) they can explode if you don't drain a used capacitor because they can still hold a charge even after removing them. Good luck to you. I'm gonna see if I blow up once my capacitors are delivered.
@@cornfusedatbest3980 Thanks for your reply! Well, all the tops were flat when comparing to all the capacitors everywhere in there. All were not lifted from the board and all did not look swollen. Anyway, after three visits to Best Buy the manager did me a favor and returned it for store credit. I got a TCL Q7 and love it. Way better.
@@bigdog8882 Hey can you please tell me the size of the capacitors if you remember.
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👊🏽👊🏽
Excellent work David!
I am not electronically advanced but you just helped me fix my tv. I’m amazed. Thank you so much.
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.
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
Mi television esta asiendo eso y no tiene un rest bottom
You reset with the power button@@chiquitasleep
@@MissSweeTSmarT1983My 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?
Thank you. You helped much more than customer service did.
Same issue with a 55R6090G5. Replaced with 400v's instead of 350v's and all is well. Thanks for the video.
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!
You saved me a tv. Followed your instructions. Great video. Thank you.
Thank you! Fixed mines watching you❣️
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.
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
Where did you get the kit?
Thank You! I have this same model TV with the same problem. You saved me a big repair bill.
Great video! Watched it once, was able to clearly understand the fix and replaced my capacitors in less than an hour! Thank you!
Great to hear!
@@bigdog8882 Hey at Minute @4:50 The plastic power button My TV has the same one I tried everything but can't get it off you got any tips on how to remove it without breaking it?
Greetings BigDogg, I’ve been away for awhile, now I’m back
Thanks for the great knowledge as usual
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!
Bro thank you so much you saved me from buying a new tv, this worked for my tv. Thank you
My exact problem. I did the capacitors. My T.V. works now. Good how to video. 😊
Another nice fix. Thanks for the tips Big Dog!!!
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.
Do you happen to have the link to the capacitor I need to order 2
Same
Thank you for the information on this Hisense fault
I tried the button and it did NOT work. I will NEVER buy Hisense ever again. Thanks for what you do and the information.
Thanks for watching. Check the capacitors, there's another video on it.
Thank you for sharing! I went to eBay & ordered the capacitors for $8…my brother followed your tutorial and 20 mins later my tv is working again lol
Thanks again much appreciation 🙏🏽
Oh and my brother said my old capacitors had burst like overheated batteries 😕
Excellent. U and your brother did a great job together. Thanks for watching.
Thanks, my parents where going to just buy a new one, i saw your video, bought 2 for 16$, got them then realized i got axles instead of radial, but they fit even though there 2x bigger lol and it works again
Thank you 🙏🏼 bigdogg for the perfect help I just replaced both of them they were both gone
it works great now 😊
Great to hear!
Awesome thanks! I believe this should fix my TV!
Thank you for this video. You save me money.
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 sir. Your method work for us as well…!!!
EXCELLENT VIDEO!!!!
Great detailed tutorial sir 👍🏽!!
Saved my Hisense TV by replacing two 10uF, 350V, 109 deg capacitors
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😅
Thanks BigDog, this got me fixed up with a similar model, a 50R6E1.
Good to hear
Good fix haven’t come across bad caps for ages
Their still around, lol.
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.
Thank U.
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.
Thank you for this video sir!!!!! Can't wait to try this
Thank you ...the Best video
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!
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!
Good tutoring brother thanks
Taking from a donor board😅. When I was working in the industry, we called it canabalizing! LOL. Nice Job! Well done👍
Thanks! 👍
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
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
An other great fix ! you're the boss man...very interesting, as always !
Great video!!! Good information
Can I use the 50R6E motherboard as a replacement for the 50R7E since must of the ones I find are out of stock.
Thank you a lot man. It worked on my unit, however, it's not receiving signal from my remote.
Excellent video.
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?
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 ..
Thanks for the help
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?
Having trouble finding this 50r7e motherboard is the 50r6e motherhood compatible to use on this hisense model?
Do you do repairs? I have a black screen with a constant bootloop and dont trust myself to do it myself.
It worked thanks
great work bd
where is your shop. I've hisense TV 43 Inches horizontal lines dribbling..and
sometimes won't light up. but
there are heard..
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?
Thank you Sir!
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.
probably bad board. or backlights. you have to have a shop take a look at it.
@@bigdog8882 hey, wow! Thank you for responding. I got given the TV, and thought I’d have a crack at fixing it. It’s only worth about $150 repaired in my market. I have checked the LEDs they all appear to be working. However, this is not verified with a multimeter-the strips are glued down, with the terminals underneath, and I was concerned I wouldn’t be able to put them back in.
I’m thinking this is a dead end project for me at my current level of ability. Would you agree?
Wow!! Thank you!!
What is that you used to keep the capacitor in place
Not bad & they are cheaper to replace than getting a board.
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)
Thank you! I’ll never buy a Hisense ever again.
I only found 400v 10mf capacitors. Will those work?
where do i buy or order them? and how do i make sure they’re the right ones?
Great video…You saved my TV! I watched your first video and it reset did not work. I opened up the tv and found the swollen capacitors. Replaced them and problem solved…. Thank you again for great video.
Can I do thi for my 58 inch model 58RGE3?? IT WENT BLACK AND WONT START OR NOTHING?
I got tv issue with pictures itself .led seems working.its seris 6 hisense tv.any suggestions what should i look for ?
I have a Roku 65" TV 65R617 with the same problem. I'm reading online and some people are recommending to change the main board. Is there potentially a problem with the backlight filter capacitors on the circuit board for the TCLs as well? Thanks
Most likely Mainboard..
@@bigdog8882 I have this same issue replaced all boards and still having the issue
About to find out with my less than 2 year old Hisense ROKU 65" 4K that is doing the same thing, if I can actually find the caps anywhere. No luck on Amazon so far.
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.
replace the board.
@@bigdog8882 I replaced the main board and no change….. so I guess I shoulda replaced the power board huh? I got the main from tv parts today so I can return it. Ill order a power board. Thanks for the reply. Your channel is great!
@@bigdog8882 my saying something storage n doesn't let sign in too google but my youtube works
I changed the LED strips and fixed the problem
@@missiletm thank u. How do I go bout getting parts I discounted everything. Everytime power up volume at 25
Nice.
Thanks!
Thank you for your great tutorial!!
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??
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.
I got the Hisense 65H10G, facing the issue. How do I fix it?
hey, rob I've fixed a couple tvs thanks to you and your vids but I got a hisense android tv model 55h9f that has an led driver board and it's new to me since im a beginner
would an led driver board make the tv turn off after about 40 seconds?
i get 16v instead of 18v on the power board but i get the 12v standby
main board, power board? thanks in advance
How much do yo think this will cost to get replace for a 50inch Onn roku tv?
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
Same happened to me with the black bar did you have any hope?
@@marvintolbert2409 I had the same black bar issue when resetting and replacing the capacitors worked for me. I just fixed my TV 15 minutes back, hope it helps.
@@waqasahsan thanks I'll try it
I came back here to say thanks, I fixed it
Your very Welcome Hoang
Thank you
You're welcome
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
Big dog I’m 8/9/82 from Chicago
Great job well done thank you for the excellent video
Bro, do you sell Mainboards? Hisense 273265.. also is the reboot loop a mainboard issue, or a powerboard issue?
Model 75H6510G Variation G2021JB
From my experience its the backlight or most likely main board.
@@bigdog8882 I opened it up, none of the capacitors are bulging ... Main board says it's 27365 per Hisense. But after opening it up it's actually 272945. I wanted to avoid buying both boards if it's not necessary. Regarding my other question, do you sell main/power boards?
I have a 75 inch Roku Hense doing the same. Do I use a 10 far capacitor it well?
probably NOT, 75 inch backlight circuit is made different.
Great vid, but gosh I would never use 2nd hand electrolytic caps in a repair for a customer, they don't age gracefully when they run hot on a buck converter like that. I don't know what the weather is like there but in Oz where it gets hot as hell in summer that thing would probably bounce inside of 12 months.
Probably best to find a higher voltage rating greater than 350 volts.
I give up. I don't dare take the back off.
I don't have any of the tools I see you using.
I'm known for breaking things especially electronics. I don't have to do anything but show up.
I guess I'ma g🎉et a new tv 😢
Thanks i have 55 inch
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?
Probably bad backlights.
Thank you
