Smart TV continually restarting

Jimm — Thu, 13 Apr 2017 09:25:32 GMT

Hopefully someone can help/advise on the problem I've got with my Smart TV (UE40D5520RKXXU).

A few days ago the remote was used to power the TV up but it wouldn't get passed the start-up screen switching itself off then trying to restart reaching the same point and shutting down and restarting again, this just goes on and on.

Now the power is switched off as it won't start but when the power is switched on it automatically tries to start but fails every time as above.

The TV is about 6 years old, in perfect condition, I'd like to keep it but only if it's going to cost a reasonable amount to sort out.

Last year this same thing happend and I opened the back up to have a look around to see if anything obvious was wrong and with a many power on/offs it started up, much to my surprise, so the back was re-attached and we had been using it without any problems for the last 8 months.

Could the problem be in the software or is it a power supply problem? Hopefully someone can come up with a suggestion or two.

Thanks in advance.

Hi @Jimm,

Have you checked to see if there are any updates available for your TV?

Menu > Support > Software Update

You can also check your software version here: Menu > Support > Contact Samsung.

Check out this LINK for downloadable software and this LINK for installing the software.

Hi TracyR

Thanks for your reply and advice, I was due to update the forum on my post.

The TV, after a week or more of testing with power on/off etc came up with a screen of 'no input source', i.e. it finally started up and only needed an aerial or other input to work. This is what happend last year where it eventually started up also after quite a while of power on/off testing and periods of no power to the TV.

I wonder whether there is a software issue though the firmware is up-to-date. I have turned off the auto power off setting in case that may be part of the problem.

Anyway, at the moment, with fingers crossed it's working normally,

Thanks again.

Regards Jim

Just to add for you and anyone else who read the OP, I wasn't able to control the TV at all when it was trying to start, I only saw the Smart TV splash screen for a brief moment before it shut itself down to try again to start, this was continually repeated. I've read on the internet something similar and was termed 'boot loop'.

For some reason, in my case, twice the TV has come out of this 'boot loop' and managed start successfully.

I have a Model UN55D6420UF from the 2007 time frame which has the same problem. After searching the internet, there are people with the same issue going back to the 90s. I paid a service tech $500 to replace the board that was causing the problem and within a year the problem came back. Clearly a design flaw.

Hi Jim,

I have the same problem! You said you did more testing etc before it came right. Do you think anything you did had anything to do with it starting to work again?

Thanks,

Pops

Hi guys,

Same problem on my Samsung UE40D5520. Identically with the description given by Jim, the TV can not be controlled from remote or from the digital buttons.

It is clear that this is a SW issue. I take a look under backcover to see if the capacitors from power supply board are damaged but everything seems to be ok. Both boards(PS board and Main board) are in perfect condition.

Could one of the moderators from Samsung advice us how we can fix this issue?

Thank you in advance for your quick feedback,

This boot loop problem has happend to me twice and both times it luckily came out of it. I was ready to throw it away as I thought it wouldn't be worth repairing though it was in perfect condition.

The things I tried to do to get it to start was to unplug all cables, it was left unpowered for a while. I opened the back cover to check the capacitors etc but I couldn't see anything wrong with it. I continually tried to restart it using just the power cable but it seemed hopeless. However, eventually it did start and I plugged in a powered aerial and selected the correct source and, luckily for me, it came back to life.

I don't know what the explaination is for it coming back to life, having tried a few minor, simple, things (as above), perhaps one of those things jolted it back to life. Is it a software problem? I don't know but I'm glad it's back to working normally and it has been since my original post.

Good luck to those that are having this frustrating problem.

Hi there, I have the same problem, as you can see in all our comments, there is no way to control the tv to search for any tv sw upgrade, we are not talking about cheap tvs, so please, help us Samsung.

Re: Smart TV continually restarting

Lucian11 — Wed, 13 Jun 2018 01:35:54 GMT

Hi Bluethug,

as you can see any of us did not received information about this issue from Samsung, but, in my case the solution was like this:

- I removed the main board from TV and send it to an electrician near Bucharest (Romania) via courier, he changed on the board an microcontroller that should be reflashed or something like this. The problem was solved and my TV is working just fine now.

The cost was 50€ including transportation ( I am from Romania).

In this instance we wouldn't be able to resolve the issue through troubleshooting.

If your TV's out of warranty, we'd recommend contacting your nearest Service Centre. If it's still in warranty, please contact our Support Team for assistance.

Hi all,

An update for those that are following this post.

My TV went into the boot-loop problem for the third time and it would not come out of it so I contacted a TV repair man and he said this was a known problem with a failed 'NAND-IC' chip. The TV is currently with him and he has confirmed that my TV does have this problem, he's fixing it now.

Ironicly when dropping the TV off to him the exact same Samsung TV as mine was being picked up by another customer who also had the same problem.

I had considered sending the main board off to Europe for a fix but when my TV repair man said he wanted the whole TV as it would also need to be reprogrammed I opted to use his service.

In conclusion it would seem that there's no lucky or magical fix to this, no software issue but a hardware failure that needs a TV repair service to resolve. My repair cost will be about £84, I didn't want to throw the TV away, I thought that would be wasteful and besides the chip failure the TV is in good condition. I'm looking forward to getting in back.

Regards

Jim

Buna Lucian

am si eu in Samsung smart de 55 care de tot restarteaza si mi mai recunoaste ordinea de conectare Hdmi si nu mai recunoaste nimic din ce conectez la TV ajutama te rog ***** Info

Hi, our 55” has been doing this intermittently for around 6 weeks, maybe once a week until today when it has just got stuck in the loop. It is just in warranty the repair guy came out last week and tried to blame it on our Sky Q box, but it has been doing it when we watch Netflix via the tv App and sky was disconnected, they are now saying it’s the WiFi adaptor even though the tv is hardwired. Just wondered if you new which board or part was changed on yours, this does seem to be quite a common problem with Samsung TVs.

So why do you not fix them?? ?

Lots of people seem to have this issue including my Nephew. He has got no where with Samsung support. He has given up and now turns off at the mains. Not good.

Paul.

Hey @paul1277. If the TV is still in warranty, the TV can be repaired by one of our engineers (free of charge if there is no physical damage). If it's out of the warranty period, it will be a chargeable repair. If the TV has been tampered with or has had an unauthorised repair, the engineer won't repair it. If your nephew sends me a message on here, I will happily take a look into his case and see what has been said. Alternatively, contact us on Facebook or Twitter and we can take it from there too.

It was only when I saw him a few months back. He told me it started about 6 months after purchase, but due to him being in the army he could not sort the issue. He did contact support and got the usual reset, and it did not work. He was never offered any actual resolution but try reset, or switch everything off to power down. He just got fed up and turned off at the mains. Thing is it does not matter if it is out of warranty if it is a known fault which considering the posters here it is then under the consumer law the retailer is still responsible upto 6 years after sale to repair.

Well my Samsung tv is supposed to be coming back this afternoon from the service centre, they reckon the reason mine was stuck in a boot loop was because of a faulty WiFi module, we’ll see how it goes when I get it back!

Placing the main board in the freezer works for my UA40J5200AKXZN problem of Boot Loop however the WIFI problem still not solved which i think because of hardware fail so the 2 issues are separate.
