...and then back on again a few seconds later.
In fact you can't actually put in standby now.
So if it's been off at the wall, it will switch on, detect the source, but then about 5 or so seconds later it restarts itself. Then is just stays in this cycle.
It's a Samsung 47" LCD, about 7 years old now. Never had any issues before
I've left it switched off at the wall for 24hrs + but still the same, so assuming is some kind of hardware issue.
Is this fixable? Worth getting someone out to have a look or are they not really repairable without replacing everything?
our old panasonic kept doing this, google said many things to fix. ended up buying a new "modern" TV
This should be in the ghost stories thread.
Ghosts?
Any footprints left behind by a sasquatch?
I wouldn't mind if the ghost just stuck to one channel, but this is just annoying.
Probably either the memory is fubarred or there's a broken connection somewhere (maybe a dry solder joint) so when the main chip does its initial checks it sees the fault and reboots, endlessly.
PM tjagain, see if you can breed yours and his
OP, are you me???
I was literally going to ask the same thing about our Panasonic plasma thingy which is about 8 yr old. It keeps switching off to standby but needs to be switched on again via the remote. Also the sound keeps 'dipping' for a couple of seconds now & again & the sound control seems to be delayed in it's reaction.
A few weeks ago It had green lines running down the screen but they have miraculously disappeared.
Try a different power cable?
Ours kept doing this and it was a dodgy connection between cable/power socket.
Snap here too.
Our 8 or 9 yr old Samsung is doing exactly the same. Started a month or so back and would settle after a couple of minutes. Now it takes me about 15 mins to get it on and then it's fine, even if you turn it back on and on in a short period of time... just doesn't like overnight off's no matter if it's standby or mains.
Will try a power cable swap.
With any faults on a Samsung tv the first thing to try is a full engineers re set, not the one you can access through the normal menu on your tv though.
Try this, with the tv turned on but in stand by mode press the following buttons in quick succession. Info, menu, mute, power.
If you’ve done it right the tv will turn on and you will have a screen full of tiny text settings. You may have to do it a couple of times as it can be a bit tricky to get into this menu,
One of the options given will be factory reset or something similar ( its a while since I’ve done one) select this and press ok. The tv will turn off then on again and restore itself to shipping condition.
Retune the tv as from new.
Hopefully that should sort your issues, if not get in touch with a decent tv engineer who should be able to give you a quote for fixing it.
I've got an 8yo Samsung that does this. Mainly a problem that it will not go into standby but also just started cycling through standby/on whilst watching.
Watching thread with interest to see if others follow the reset advice above..
What is the model number Essel?
It is telling you to go do something better instead...
I don't know of anyone who will even try and repair plasma TV's. The big issue with plasma TV's (and to a lesser extent all modern TV's) is they run very hot and its the thermal cycling that kills components and exposes dry joints. They also tend to use cheap capacitors especially in the power supply, heat kills those so any "old" TV's would benefit from a re-cap as a matter of course.
A Samsung TV I had did exactly this. Richer Sounds tried to fix it 3 times under warranty but in the end they replaced it.
The internet says it might be fixable by replacing one or two capacitors on the power board. As mine was under warranty I didn't try this.
Our LG telly did similar, it also started to take longer and longer to turn on after being in standby.
Some googling says it is an issue with the board that deals with incoming power and power management. The boards are available online, some are a plug and play swap and some need soldering.
We took it as a chance to upgrade the telly but I have kept the old one to see if I can fix it for the kids gaming.
Same here. Our Samsung will occasionally switch itself to standby for no reason. PIA but it's modern technology so all we can do is put up with it or get a new one. A new one is just as likely to do the same!
very likely the power supply board capacitors - fixed my Samsung with a second hand board for £20

Yep, ours too - 5 years old or so. It would turn itself off now and again, you'd assume someone had sat on the remote or something, became progressively worse.
Seems 5 years is really old for a TV now and not worth fixing.
Used it as an excuse for a new 4k, which is bigger, Smart and better in every way, also cost half as much so they're probably not worth fixing any more.

This. Happened to mine about 6/7 years ago I’d had the TV 5 years at that point. Samsung sent 2 blokes out to fix it FOC and it’s still working now (albeit on its last legs...)

Were the capacitors visibly damaged?
The capacitors were very slightly bulged , a power supply board was cheaply available on ebay .
I would have replaced the capacitors but its a pain to have a TV in bits waiting for the capacitors on order as I did not know the values .
On ebay capacitor kits are sold for various TV models/brands if you want to diy - take note of precautions when working with capacitors and if possible get somebody who is handy with a soldering iron .
Its 3 years since I replaced that board and TV is fine.
Just checking on ebay there is a seller who will replace the caps on your board for £28 by return service - seller electronicavenue - I have absolutely no connection with seller I just looked on ebay.
So as long as you are prepared to take the back off the TV and take reasonable precautions you can DIY
My old Samsung did the same. I looked into fixes at the time but it was basically just two things you could replace without getting a soldering iron out. Power board or main motherboard.
The cost of the replacement boards and difficulty of getting them made it not worth it and I'm not a whizz with a soldering iron.
New TV.
I hate disposable stuff like this but the industry is set up like this now. I've had similar with previous TVs too. Advice from manufacturer (always out of warranty of course) was to just bin it and buy a new one.
My latest Samsung doesn't have quite the same fault but it does do a reset sometimes around 5 mins after initial power up. Often pops up that the Smart TV has been updated just after (I never use it). I think that's a software issue. The old TV seemed intermittent and more of a hardware fault.
Other annoyance of my current one is it will also switch itself on doing some kind of update and then turn off. It causes the backlight to come on when it does that.
I found out it was that perchypather chappie messing with my TV and my head - so I suspect this one is the same

Less boring, no?
What is the model number Essel?
It's a TX-P42G20B
Our LG telly did similar, it also started to take longer and longer to turn on after being in standby.
Back in the day when I was a Sky engineer the Sky Plus boxes and some of the 1st generation HD boxes used to have the exact same issue, it was down to piss poor capacitors in the PSU failing.
Could be fixed by having the PSU rebuilt with new/good quality capacitors or swapping out for a working PSU(which would inevitable fail at some later point).
Sounds like a similar issue.
I used to repair crt Tv's back in the day.
Op, your tv is "pumping". That's what it was called back then anyway. It's trying to start, detecting a fault, shutting down again.... Then repeating.
BITD it could be caused by anything pretty much but back then you had to fault find to a component level. Spending a whole day sometimes to find one knackered component. The good old days. Kind of.
None of this helps you mind but if it's a capacitor it might well look fine visually. A few years back there was a rash of PC motherboards going pop as they had cheap/nasty Chinese made caps on them. Suddenly you started seeing mobos being sold with "Japanese made capacitors" emblazoned on the box.
Bitd tv's had some big old caps fitted in them and they did explode occasionally. They went off like small bombs.lol
Anyway, good luck op. Hate to say it but I'd be inclined to get a tv on 0% interest or such.
Thanks for all the suggestions. There are a few things I
lol try now, but it looks like it’s time for a new tv.
A few years back there was a rash of PC motherboards going pop as they had cheap/nasty Chinese made caps on them.
It wasn't that they were cheap, exactly. It's a rather curious tale of industrial espionage.
An employee from a company in Japan stole the formula for an electrolyte and took it to a Chinese firm. This went on to be copied all over the place. Except, it was incomplete and unstable. This was used, largely innocently, in loads of caps coming out of China and Taiwan. Hence, a massive long-term reliability problem with many electronics products produced throughout most of the 00s.
^^ Interesting tale there mate. Never knew that. I love that sort of back ground story.👍
Its why I have to be careful on Wiki.... Go on there for "10 minutes".... And 2 hours later I'm still on it! Lol

Just spoke to my tv repair man and he says that’s more than likely the main board that’s gone. You would be better off putting the money towards a new one rather than repair it.
