Come on Samsung.. 3 years old and a common problem ??

[@TorFoss300]

Nice fix. So Samsung admitted faulty firmware. Had a JVC LT-50E73 that was dead. Could not find the fault. By chance I got hold of more of the same model. Hoping to swap parts. Different fault on all of them. No luck. The "experts" all had different solutions to no help. Finally found firmware online that JVC said worked via USB. No luck. Last attempt was to connect the mainboard to PC via a CH341A. Flashed new firmware on all the mainboards. The result was 5 working TV´s. 😀

Love your videos, as a hobbyist vintage computer repairer (ZX Spectrum, Amiga etc,) your knowledge and walkthroughs are great and no doubt are a valuable source of reference for repair for years to come.

When I was a young lad, I worked weekends at a local TV repair shop doing whatever. Now I don't know if you folks in the UK ever had the Motorola "works in a drawer" TV. Anyway, Len (the shop owner) asked me to help him deliver one of these sets to a customer. We duly arrive with the TV, put it in it's place of honor, plug it in, turn it on for final adjustments, worked like it should. Then the customer asked to see "the works in a drawer", sure says Len (the drawer feature was for servicing and no need to turn the TV off), so Len removes the fastener holding the drawer in place, pulls it out for the customer"s viewing pleasure and the TV shuts down, that's odd says Len. So we took the TV back to the shop and next day had a go at repairing it. Seems there was a change in the design and a half watt resistor was soldered in place between the chassis and the drawer circuitry, there just wasn't enough wire to allow the drawer to be opened, when Len pulled open the drawer, the action pulled the resistor apart causing the TV to turn off till repaired. Shortly after the Works In a Drawer TV campaign finished, Motorola announced it was no longer going to make televisions, they were going to focus on their communications operations.

I remember those, not the best design I ever saw. Also, not the ugliest. Was quite reminiscent of the Zenith slap board design, which had occasional connection issues on the gigantic pin connectors to their modules. RCA having a modular offering, with the fewest modules possible and basically being a gimmick. I remember one Philco unit I worked on, used a gate turnoff SCR for the horizontal output, of course that one being a favor job for a close family friend, it had to turn into a science project. Carbonized sections in the horizontal output section, arcing, resulting in a blind spot that I return to this day as a new section of board failed. Managed to fix the infernal mess, damned damper diode had opened, resulting in the arcing mayhem. I'd never observed an open damper diode before or since. Then, there was the North American Phillips offering, infamous for a pair of 47k resistors in the vertical output circuit burning in half. I never could figure out that failure, common problem, no possibility for a half watt of power to be dissipated by those resistors, yet burn they did. Could only think that they'd bought a batch of bad resistors and over time, they'd just fail. Can't recall offhand, think it was NAP, but I'm probably off target, who had a vertical deflection issue that'd send the electron beam straight through the neck of the CRT... Ah, the good old days, back when the quality goes in before the name goes on, then they'd yank the quality out and stick it into the next unit on the production line... ;) Joking, everyone fouls up from time to time and the common problems were an excellent source of income. I ended up advancing to become our county's 'tough dog' guy, where other shops would send me units they couldn't figure out or my shop phone would ring with other techs that couldn't figure out what was wrong, that was fun though. The tougher the problem was, the more fun it was to fix it, the more satisfying it was to solve that particular puzzle. actually understanding what circuits did what and why made troubleshooting a lot easier, with ever so many techs out there just not having a clue on the circuit theory behind what they were trying to repair. Thinking in the algorithms needed to properly troubleshoot also prepared me for military service as an advanced medic and that career, from which I'm quite happily retired. Well, off to prepare for a medical appointment. Got an issue that's confounding my primary care physician, hence the specialist appointment. Oh well, there are worse things than getting older - such as not surviving to get older. I've yet to receive good reviews from friends long departed on the afterlife, so I suspect things are as dodgy there as they are here...

Well done on replacing SMT IC with soldering iron Allen, love the content. I've done main board swaps and power supply capacitors on some tvs myself. Need to tackle a backlight next😀.

Hi.. I have a Samsung tv and that’s only a couple of years old and doing the same thing.. so what was it you replaced and where would I order one from? What’s the cost of this.. will give it a go myself and see what happens.. thanks..

[@healeydave]

Personally, I wouldn’t touch Samsung with a barge pole. There was a class action lawsuit against Samsung in the United States for charging customers for known premature failures. I used to own a short term rental in Florida and had 5 Samsung TV”s in 4 bedrooms and one in the lounge. 3 out of the 5 tv”s failed within 3 years. They sell with high specifications but assembled with the cheapest components. I vowed then never to buy another Samsung product and 8 years on, I am still true to my word and telling everyone that will listen about my experience.

[@Dragunov1111]

Not all samsungs are the same... If its Turkish Vestel then you are right if not they might be good.

[@davidgapp1457]

The problem is... which TV manufacturer is any good? I bought a Hisense 65h9g back in Nov 2020. It's used only sporadically but failed in July 2024. The fault lies with cheap components on the motherboard and yes, it's a known failure that many customers have experienced (cheap memory). I couldn't find a new motherboard, probably because so many people had the same problem. I was able to get the board repaired with a much superior memory chip, but I despair of finding a manufacturer who I can trust.

[@healeydave]

@@davidgapp1457 Yes, its definitely a minefield, another thing to watch out for is who actually makes some of these brands because you could end up with the same manufacturer under a different name if they're making sets for another company. I am doing well with an aging 55" Panasonic. I bought it back in 2012, so it's 12 years old and operates for around 10 hours a day, day in day out, dare I say it, still going strong.

[@andythomas7931]

Thank you Allen very much indeed.

What's the odd 100uF capacitor with the metal clipped in base?

[@steveblanchard7293]

Same problem on my Samsung 4 years old, had a row of flickering pixels and a second row appeared, then the TV went off. It cycled on blink two blink and off. Put it outside for Scrap and the scrapman managed to get it working as he accessed my Prime Account.. Now running a June 24 LG nanao LED. Picture is fantastic, however the WebOS and Apps are sloathy (slow).

[@GordonHudson]

I have a 12 year old Samsung TV in the kitchen that was previously my main TV. The one I replaced it with has now been replaced twice. I'm not going to buy another Samsung but it's hard to know what to buy next time. I don't use the smart functions or the tuner.

[@fus149hammer5]

Agreed. Who really needs a smart tv when most of us get our content through Sky, Virgin, BT etc? It's all there, Netflix, Amazon, Iplayer, even games consoles have most content. Ours is basically just a monitor.

[@iBoR3D15]

I have a Samsung monitor with back light issues two years in and this monitor wasn’t cheap. 🤦🏽‍♂️

[@StephenLowe]

My Samsung TV half the backlight went to I replaced it but went with a different company as TV was just out of warranty

[@stevenhughes6282]

Surely a hot air gun would have been less detrimental to the heat you applied with your soldering iron. I was wincing all the way through your soldering although I will admit that I cut my teeth on germanium semiconductors. semiconductors.

[@AndrewAHayes]

I have a Samsung TV that I keep in my reception room and hardly gets used and the back light on the right hand side has gone, it was only 18 months old when it went, I would have changed the lights but as I say we hardly use it. I also bought a 70" Samsung TV for the lounge that had to be retuned every couple of days, initially we thought it was the antenna that was at fault but we had a new one fitted and the problem still continued, we don't watch broadcast TV any more, just streamed content and Blu Ray disks and they are just fine and so we haven't bothered replacing it. I will never buy a another Samsung TV, I bought Sony products prior to the Samsungs for decades and never had a fault with them, in fact the tube of the old Trinitron was converted to a monitor for my arcade game cabinet and still works to this day, I think I bought that in 1998. By the way that TV looks filthy!

[@GF-mf7ml]

Sony make the best TV, they're expensive.

[@fus149hammer5]

On my Samsung 50" you can't completely turn off the contrast enhancer setting. Bloody annoying when watching white end credits on a black backgrounds or something on Star Trek with scenes in space. You can actually see the image darken. I can only turn the effect down not off. I keep hoping for a software update to sort it but after four or five updates I've given up. My local branch of Richer Sounds ( not where I bought it from) know about the problem and say it is quite common. Next time I'm going for a Sony.

[@guruoo]

Your next video, 'The Great LED TV CON' has comments turned off, and I wanted to let you know that the animated symbols on the screen tells me the problem is most likely to be with the android OS it's using, rather than the TV itself. A simple Android system reset just might fix it! Google android tv reset and the part number.

[@Barbarapape]

Another example of why the recent models from most brands are made down to a price. My advice is buy a new TV from a retailer that includes a 5 or 6 year warranty, and if the set lasts that long, just keep your fingers crossed that it will last a few more years. How many of these entry level sets will go straight to recycling when they fail ?

[@fus149hammer5]

That'll be Costco then or John Lewis. No chance getting that length of warranty anywhere else.

[@fus149hammer5]

TBH we bought a 50" 4k Hisense around five years ago in Argos for a ridiculously low price of £250, far lower than anything comparable at the time. Trouble was it just kept on working and the missus flatly refused to upgrade when we had a perfectly serviceable telly. How strange that one day the picture got stuck on RGB mode.........😂

[@Barbarapape]

@@fus149hammer5 Here in the UK Richer sounds have a 6 year warranty and lower prices if you join their free VIP club.

[@Steve30x]

I had a Philips 58PUS8535 which the screen went completely blank after just 13 months. I was watching hung a 4K blu ray and when I turned off my blu ray player the screen went blank and no matter what I done it would not come back on. The screen just suddenly gave up wanting to live

Strange why they would recommend using a soldering iron to resolder the new chip unless techs are using very high heat to desolder lead free solder on that side of the world.

​@@dimitrismastergiven how common this issue is, have to wonder if it would be a good idea to take a copy of the firmware the second a TV goes out of warranty.

@jasejj the problem as well is the bga nand chip that contains the main firmware,the sop8 contains just the core bios/bootloader,the first one dies often as well.Good luck finding the main firmware and load it at a new chip.
