I have a UE32D5520R with the same issue. The paper clip reset trick worked about 6 months ago but now it’s happened again. Must be the chip. Time to find a new chip as the TV is otherwise fine. Cheers for the video!
Paperclip, freeze spray, did nothing for me. Neither did the cheapie Chinese chips, so make sure you get one that's properly programmed. Costs a bit more, but saves sitting thinking "Did I blow something up with the soldering iron?"
My beloved Samsung UE37D5520RK has just decided to join the rebellion against the human race and go into boot loop mode 😡 I’m perplexed but fortunately found your video and after hours off scrolling google and the tech forums your video has filled me with hope. Very much appreciated hope it works for me too👍
Thank you! A refreshing change to have a positive comment instead of narrowly focused personal abuse (sorry, just so damned sick of the bottom feeders that love to infest this place). I've not managed to be completely sure of the underlying cause of bootloop If it's a dodgy update, or failing memory hardware, but I've fixed two or three of these now by replacing the NAND. Only issue I had was a cheap "Chinese" chip just didn't work, but the European sourced ones have been perfect. Hope, as you commented a while ago, you had success!
Sure. I really need to spend some time going through and dopping timecodes and seller links and stuff in my descriptions on the FoP vids. Takes a few days to arrive, but not an eternity. www.ebay.co.uk/itm/142618310138 I think I mention in the vid I've had two from the same seller, both have worked perfectly.

@@superniokas Fingers crossed for you! I know nothing about programming nands, but assume either the cheap Chinese ones aren't actually programmed at all, or they're done in a way that is incompatible with the TV mainboard. Hope that Slovakian one came through for you!
Unfortunately the guy I bought mine from seems to have stopped doing them. And the cheaper Chinese ones I tried were useless. Best bet is probably to look on Ebay for people in Czech Republic (for some reason they seem to have the right firmware files), although I think a Spanish seller was also offering good programmed chips. Good luck!
My UA32D5900 which I was using as a computer monitor has same problem and gathering dust for around 2 years. Whenever some one posts a potential fix for this Samsung Boot loop I try it. I have not done desoldering/soldering or programming, remaining most I have tried. The problem started when one fine day, I tried to hook up an older Panasonic Handycam/Video Camera. Both TV and Camera were powered and I tried to hook up the TV Component Cable. Moment the cable from Video Camera touched the connector on TV there was a reboot. Possible voltage difference between two non grounded devices (both Camera and Samsung TV are two pin AC powered) caused a problem moment they connected.
Sorry, not been checking messages recently. Hmmm, I hadn't really thought about shorts or power surges causing these issues - The two sets I've done were both allegedly "working fine, nothing plugged/ unplugged, just started doing this". Maybes yours was just coincidence? Although it does sound like electrons going where they shouldn't! As mentioned in other replies, I tried all the "easy" fixes, and all they got me was an expensive empty tin of freeze spray and collection of no longer paperclips. Soldering's been a sure fire fix, and I surprised myself with how easy it was!
So that chip is the RAM? Or with memory you mean storage? Is it a RAM problem which causes the loop? In my case the remote controller works, but for the rest the TV has the loop exactly as yours.
Seems to be, from the two I've done and what I've read, the storage memory - The flash memory/ "hard drive/ operating system" chip. Must admit, I'd have to pop open one of my TVs (which I'm using, so prefer not to!) to see if there's a separate RAM chip on there. Some people have said the loop starts after an update, others seem to think it's just that the chip goes bad. Think of it like a computer where the hard drive's had it - It might try to load, but then just gives up and restarts. Forever.
It seems the seller I bought my repair chips from doesn't do them any more, which is a shame as they've worked perfectly. This www.ebay.co.uk/itm/164439142100 looks like it ought to be OK. I'd avoid the $5 ones, I tried one once and it was a total fail. Good luck!
I honestly don't know the best way, as this is more an entertainment channel and I just like dicking about with broken stuff as a hobby. But I guess the easiest way would be sourcing a known good replacement mainboard, if you can find a sensibly priced one.
Hi mate I've got the exact same problem, alot of people I've asked say its the back light and others say its software, is the software chip most likely the problem, mine reboots the exact same as this one
I've fixed 2 D5500 TVs with this symptom now, a 32" and this one, both times it's been the Nand. I don't know enough about TV repair to say it *can't* be the backlight on yours though, but from everything I've read backlight doesn't cause bootlooping does it? I'd tried the "reset it with a paperclip" advice I found on youtube, as well as the "freeze spray it then run an update", and neither did anything. Buying a cheap allegedly programmed nand was also useless. Paying that bit more for the properly prepared nand fixed both TVs, even with my terrible soldering!
Seeing the comment below (which I missed because RUclips's beta studio sucks, hard), the seller I got my nands from isn't selling them any more. But seems a few others are. I'd really recomment going with those over the cheap Chinese ones, after the cheapie I first tried didn't work and left me wondering if I'd misdiagnosed, or worse killed the mainboard when soldering.
I got mine from a Slovakian Ebay seller, but apparently they don't have them now. I've seen a Spanish seller seeming to sell the same chips. I'd advise against getting a cheap (like, £5/ $5 one) from one of the Chinese sellers, as I tried one and it didn't work.
Hmmm, seemed this stupid thing ate my reply. I can't help with that, sorry. Don't have a programmer, and as there are sellers who offer fully working programmed chips for very good prices, I didn't investigate sourcing ROMs for these.
Hello people not to out do the effort on the video there is a slightly simpler way to sort this out. you can freeze the corrupt chip using freeze spray while the tv is connected to the internet update the software it worked for me. I had nothing to loose I got a freeze can from the plumbers merchants £10 sprayed it till there was ice on the actual chip and kept spraying it to keep cooling it while the software updates. Apparently the software Is corrupt not the chip. I figured repair shops wanted £70 plus post and used tv is cheaper I didn’t have much to loose
Tried that (can't seem to find the footage though) on my first D5500, and... It did nothing. I've seen it work for others, but I guess it's maybe a matter of luck, or down to the root cause of the problem. For me, no amount of paperclip, freezing, making a chicken wear a goat suit and recite the US pledge of allegiance backwards, worked. The only thing that has has been replacing the NAND. I have wondered why the freeze does, apparently, in some cases work. Does it cause the chip to lose its programming, or does it contract the tiny little circuity things inside enough to get it to boot?
Exasperant I was sceptical about it nothing to loose as such. Theory about freezing is that the chip is fine it’s the software that’s corrupt. Keeping it cool while putting updates seems to do the trick. ruclips.net/video/bJ8HSLlOwA8/видео.html He actually shows the freeze working
@@exasperated You asked why freezing sometimes helps. The answer is not easy, because there are several factors: As you expected, the chip will shrink briefly, but at the same time its conductivity will temporarily improve. Then some undecided data bits will temporarily acquire the correct value. This is due to the fact that every NAND but also NOR Flash, EEPROM and the grandpa of these EPROM and PROM chips suffer from the same problem. This problem is related to the fact that during writing, some cells are charged and some remain discharged. E.g. in the case of classical EPROMs, and it does not matter whether they were American, Taiwanese or Russian or Czechoslovak, all cells without charge have a binary value of 1 when read and cells written with a charge of 0. After a certain time, the charge from the written cells disappears and it happens that some of them cannot decide whether they are 0 or 1. This is related to how state 0 and state 1 are defined in digital devices. So if we take the old CMOS EPROM, the logic is as follows: 1 = minimum 3 volts and maximum 5V + -5% 0 = 0 volts and a maximum of 2.5V If the output value of the cell is in the indecisive range 2.5-3V then sometimes it is 0 and sometimes 1. Difference between old EPROM capacity e.g. 2kB and among NANDs with a capacity of 2000000kB is that in the EPROM the information disappears after 30-50 years and from the NAND this density of the MLC type already disappears gradually several months after writing. But why NAND content can work for 4-6 years without error is that the manufacturer is aware of this phenomenon and so the basic TV software, which is not in this memory contains an automatic algorithm that can correct up to 24 erroneous bits (3 bytes ) for every 1024 bytes of memory, which ensures that the recording is repairable for up to several years. It also follows that the NAND chip itself is not faulty at all, just that some parts of its contents have never been restored, because the recovery of the charge (erase and write) will ensure the disappearance of errors and the content is reusable for several more years. However, the creator of this TV operating system did not create a perfect solution in the sense that the software upgrade not erase the entire chip and re-write everything, but only some parts of it will be erased and write again. P.S. I am the seller from Slovakia that was discussed here :)
And how do I know all this? Because I already worked with it during the Iron Curtain and despite the reagan embargo we were at the world level, even though the propaganda in your country claimed that we live in ground holes or slams, everyone wants to escape to Austria and we have nothing to eat ... ruclips.net/video/_sWHG-8JVy4/видео.html
Freeze the nand instead of replacing the chip, download software from Samsung, freeze nand to -40 and keep doing it until loads of ice on it Turn tv on when it stays on it will for ages longer then the 5secs for example, now the tv will update via usb downloaded from Samsung
I wasted a whole can of freeze spray (I found the original vid files from when I did that, but ye gods they're low quality!) trying that, and... Nothing. I know it sometimes works for others, but a can of spray costs nearly as much as a working programmed chip - And if it doesn't work, you've still got to buy a chip anyway... I was quite annoyed by the whole thing the first time, I'd bought a broken set to fix as a present for someone, based on RUclips telling me "freeze or paperclip it", and neither did anything useful. Although the same went for the first chip I got, which was something like £5 delivered from a Chinese ebay seller...
