I am a not so mechanically inclined person. Thanks for the GREAT instructions. Others thought I was crazy when they saw me open the back of the TV and try to fix it with Scotch Tape. IT REALLY WORKED! It took time and patience, but I found the problem pin. You rock!
nice
@@NewsonsElectronics instead of using tape, i saw somebody else using paper , to roll sigarets with .......
This was the best video I found to diagnose my TV after I replaced both boards. I’m glad I already replaced it 😢 Thank you!!
I am having the Exact Same problem! Thank you for this, ill try it now and will get back to you later
This video Great, isolated the problem with the tape and have picture back on. color a little off due to bad circuit but it is watchable. I was close to ordering replacement board which would not have fixed problem, thanks again for great video
Hi , I fixed that problem. Underneath the left speaker, there is a ground tape that was not properly installed. It was over a few circuit line. I removed it and reinstalled properly and Bingo Tv worked again. My guess is with speaker vibration over time it made a short circui, it was after 4 year in my situation. Good luck!
What ground tape look like. What size tv u have. .
Will a resistance check on the traces help identify any shorts?
So I have the 55" version (same model). It was doing EXACTLY what yours was doing; power cycle every few seconds, then come back on with no video, but had audio.
Finally, I unplugged everything connected to the back of the TV and held down the power button for about a minute. When it came back on, it no longer cycled, HOWEVER, now I have a ~2" wide Black vertical line. I tried the cable connection giggle, and switched HDMI input port, but the line stays no matter what. I used an ESD safe orange-stick to apply slight pressure across those amber ribbon-type cable and noticed a very slight flickering of the Black band, but that's all I could get it to do.
Any thoughts?
I used the tape method and got it to work. One side is perfect the bad side the tint is way off. Could this be a firmware issue or the panel is SOL? Also why does Samsung locked down the firmware so you can try the previous version?
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.
I tore one of the COF ribbons under the right speaker when opening it with the butter knife. Any way this can be replaced without special tools, and where would I find that part? Only videos I find on this are in Hindi.
Fixed my TV following these instructions. Thank you. The colour on the left is strange now. Is there a way to buy a replacement strip?
I am having the same issue with color. Did you find a way to solve it? Thanks
Hi. 1st sorry I am from Slovakia. I have similar tv but exactly same issue and lcd panel. Soooooo Whats the issue?
So with Samsung TV's sometimes the boot loop is due to a faulty EEPROM.. As for the tape method in general, It should be noted that this is not 100% full proof method. I am not in a big city, but I see a dozen or so TV's a month at my shop and this method works better on some tv's than others. It's generally a driver ic issue and unless you have a fancy hot bar press like in china factories - you not be replacing those ribbons by hand. As Newson stated, it is almost never the capacitors (Ive never seen this either, although some videos on youtube say otherwise). I have never had 100% success with the tape method either, it's super time consuming to narrow down 1 or 2 pins on the ribbon that are at fault and not cost effective for a repair shop. (atleast for myself). At best it is a bandaid fix , I tell customers it is similar to patching an exhaust verses replacing. It buys the customer some time with the tv if it works. Best case when it works you generally end up with horizontal lines of some sort that you do not see when 5ft away from the tv.
Long story short, if buying a new / used tv is not in the budget. This buys you sometime. However, generally you are just using these tv's for parts as painful as it is to see a tv go to waste.
Thanks for sharing good advice
I have Samsung UN65MU7600F ( VA, Edge LED, 3840 x 2160 pixels )
It all of a sudden started re-boot like in subject video
I traced the issue all the way to the Panel drivers boards
TV has 4 Driver boards ( each of them have 4 chips on ribbon )
Disconnecting ANY of 4 driver board gets the TV going ( w/o picture of course )
So essentially ANY 3 boards are fine, adding Random 4th one will cause boot cycle !
Any ideas?
Power supply issues?
Its funny i have a Samsung UN50TU8000FXZA and it suddenly started to auto reboot I literally left the TV on to go make breakfast came back and saw it like that tried to identify the short circuit and put some tape on it saw horizontal lines across my tv and knew it was done for.
hello ...... question my tv goes in the reboot after half our ue40es7000, i found it on the street, and use it maybe 20 min in the week ....... tilll now he had be okay some small picture problem but not irritating. when i ope the back side i don t see strange things ...... only on the connector cable comes from maniboard is see on the connector (on powerboard ) braun spots ( grey cable side, the others are black) i gonna try now this tric with tape , when that not works witch board i must change the powerboard or the mainboard?
thanks for your time and answer
This helped me get out of the loop finally but now theres no image only sound. Lights are on and everything
Same
I see that you're located in Canada, would you consider fixing mine?
Thanks for the video.
However what do you do if you find out that the issue is from the left side LCD panel?
I current have that issue with two of my TVS and seeing that they is whether the white ribbon cable is connected it, I can’t simply use the tape method.
Await your feedback. Thanks
Maybe Cof IC is shorted. Wonder how long it will last with tape method
I disabled one half (the tv is the same as in the video) it stopped booting but still no image on either side, it doesnt matter what side i disable does the same
My tv didn’t even last a year. I will never buy another one like this.
Most TVs are not great, Samsung are just junk now, best to buy Sony OLED tv
@@ImranAli-rp4kdahahah OLED Sony. Stupid
This method only works with double belt panels....its very frustrating dealing with one belt
Would you say this is a widescale problem in these TVs and will I have ANY luck trying to get Samsung to replace this? It's so frustrating because I have this EXACT problem and I've only had the TV for about 2.5 years!
Feel your pain
Me too exactly 2,9 year
@@RichardmpayiTnway had to throw mine out was a problem with a short circuit
so, tv finally is turning on and i have narrowed down the pin, but no image on display still. just backlights and sound
Same here, any suggestions from someone, appreciate.
Same here. If you found out why I would be happy to know
I believe bad capasitor mines did the same thing sound and everything
Did you ever fix the issue on this TV? I tried the tape method and moving the tape but with no luck. It fixed the rebooting issue and screen does light up but still has no image.
yes need to find the short on lcd panel then cut some traces
That makes 2 of us
Would a new ribbon solve the problem?
Thermal camera or alcohol to show what's getting hot?
good to know
I hoped this would be something other than the tape method.
For me I have a 70in. Tape method does work but there are horizontal lines disabled. Looks halfway decent from a distance away.
So mine is 8 pins. I am still trying to figure out if I can let up 1 pin. But having trouble finding which one I can uncover to lessen the problem.
So for those trying to figure out the tape method. Just like he shows you have to disconnect a ribbon cable on the panel boards, turn it on, see if you get a picture. Because the board is disconnected, you will see nothing but white on that panel board.
After that, cover up half the pins on one side put the ribbon cable back in and see if it boot loops. If it doesn't boot loop, you know you have the right pins covered. Cut that piece of tape in half and cover half of those pins. You can narrow it down to isolate the right pins. But because pins are covered, the image will not be the same as before.
si esque esto más bien lo tiene que hacer un técnico en tvs calificado .
2 small détails: My SAMSUNG UE58TU6905 TV works again as original, without tape.
To remove the feet: simply give a light punch to the axis of the foot to disengage it (No screws)
I pulled the wire from the power supply to the main board and back lights stayed on. I disconnected the small ribbon cables one at a time on each side at the bottom and nothing changed the tv continued to power cycle. I'm thinking one of the boards. Any thoughts??
I would use an led test to test the voltage going to the backlight see if they are the same
@@NewsonsElectronics possible bad power board? Someone mentioned he thought it would be the main board. I have a stand by light.
Have both boards available for this model unxxTu7000
Hi , I fixed the same problem… now blue screen and sound working…how to solve this problems… can you explain me and your support please…
Had one try tape all over never worked end up scrapping it for part's
I had the same problem, with my 55" Samsung Qled, the fault was as shown in this video on the small cable on the right, I found the exact place by moving a small piece of tape, then I cleaned it first with tape and then with tuner 600 contact cleaner, and now my TV works again
this happened to me. I got the screen to light up and fixed the reboot by detaching the lcd bridge ribbon cable, but there is no image.
So I’m guessing my screen is a dud.
I saw replacement screen online and it cost almost the same as new tv 😢
Same problem here. Found any fix?
I used the tape method and it work, but the left side of the tv not showing real colours, right side colour is very clear, if I buy new panel cable will it fix my issue?
Thanks
no
There is pink layer on the left side of the screen, is there a way to fix it?
Fucking samsung tv i have the same problem
The fix only lasts like a day and then I have the same recurring issue. I tried moving the tape again and managed to fix it, but the power cycle comes back again the next day. Did you also have the same issue ?
no try moving the tape making it thiner
I have the same tv and the same exact problem. I followed all your steps but afterwards the screen is the blue blank screen. Did you find any solutions?
move the tape a bit
@@NewsonsElectronics We’re you able to get yours to work after moving the tape?
los displays están siendo fabricados para que duren menos y la cosa es que no es nada más poner la cinta en el conector y estar probando a la suerte de que funcione, porque este procedimiento se tiene que hacer con información precisa de los datos que maneja la tv , y aunque llegara a funcionar se tienen que hacer ajustes de voltajes necesarios para alargar la vida útil del display. les digo esto porque me dedico a reparar pantallas y aprecio que las personas intenten reparar las tvs, solo es investigar un poco más porque el intento es bueno solo tienes que ampliar tus conocimientos. un fuerte abrazo !!
Hi how can I fix my samsung ua70tu7000u ? Its turns off and on
Hi Newson, did you find the bad capacitor? I have the same issue and am on the hunt for the bad guy :-)
Same here tape just led to black screen... so as he says in this video even if you find a bad capacitor - it is easier to buy a new TV unfortunately...
Worked !!!! They threw out this TV at work because it got wet . . .as it was in the trash bin
nice
If anyone needs the new panels for this model I have both of them available !! As this trick was frustrating to do and I almost gave up...but it's a $700.00 smart tv ..so I had to at least try it ! Surprised myself seriously here . . . Free tv
@@markaylynndormire3341 i had the same situation but One side color is pink is that fixable
On mine it was 17 to 21 pin on the left side of the ribbon
Never pry up from the bottom. You will wreck the ribbon connectors to the screen.
I have the same TV that is only 2 yo. It 's doing the same thing and i did do the tape method that worked on an older Insignia 50" TV. but not on this one. I am pissed that it's a Samsung 2 year old and is junk now. Very disappointing.
Im in the middle of the same exact issue! Im so pissed. 2 years old and its garbage - wont be buying samsung tv again, thats for sure
I was right there. I cut a super thin strip of tape and used tweezers. Started at one end and moved one pin at a time across both the ribbons on the bottom. It took nearly an hour, but IDK about you, I can't earn enough in an hour to replace a 50" TV. It was worth my time. But I do agree... will never buy this brand TV again. Mine is only 2 years old too.
Mind died exactly after 1yr 6 months. When the warranty expired
@@nancybracy9649 Hey Nancy! Was the problem only on one the ribbons for you? Or maybe both (left and right)?
omg
my tt same model just stopped working
the tape method didnt work for me... do anybody have any manual or schematic for this peoblem
I found a way to make it get out of the power on/off cycle too bad I can't post pics here
TU model sucks I have a panel here with a dead short that also blows the main board, junk
Это не решение проблемы
this model wont work, same goes with 49,55 inch all is plague with this problem, dont buy samsung stuff
