Hi Adrian I believe you said that your power supply was set to 9 volts, If so you should not test individual bulbs with it set to 9 volts. This would explain why led's were blowing up as you went along during your testing. You can supply 3 volts max per bulb times the number of bulbs in series and find quite quickly which row is the problem, then when you find the faulty row reset your power supply to 3 volts max and go looking for the problem , one led at a time. I don't think I heard you explain to viewers for them to dial back their power supplies. I am a technician of 45 years. Hope this helps people out. W

Hello, Adrian, good to know your channel. I've worked in Samsung's Customer Service for years, here in Brazil, and I've seen thousands of defective TV sets like these, from series E, EH, F and FH. Just to your knowledge, series EH and FH (and all series with xH mark) are refurbished and "testing" models. You can notice that just by looking into EH and FH, some models (at least in Brazil) are exactly the same, with few modifications on PSU and main board. This problem with LED bars happens because the PSU always have a bigger voltage than expected, when the client changes the parameter "Backlight" in the menu to the maximum, the voltage in this particular model goes up to 140VDC at some point, with peaks between 100~125VDC. What I usually did is changing some resistors in the PSU to put down the voltage to maximum 100VDC on the inverter, because this LED bars gets REALLY hot when in use, and often the client comes back with the same problem. It happened four times with a client, who used to connect to an Xbox 360 and gaming for hours, and I have to modify the PSU to not destroy more LED bars. And, please, be careful with the live cell (the LCD display, it's the name that they give to it, don't ask me why :P ). The good way to mount it back is the opposite way that you dismounted in the video, putting the live cell for last, allign it, because or break it when you are moving, or break it when try to close the outer frame. My personal experience when I started to work on this repairs. Congratulations, and thanks. P.S.: I've forgot to mention: the SamyGo projetc have lots of documentation about hacking Samsung TV's, BD players and home-theaters, how to access the TV through serial port and more. Good Luck!

Lower voltage is the key. Things lasted longer when we had 110 or 115 volts ac. Now days line voltages are 125 and even higher, I had issues with my led Christmas light strings, I would lose at least 4 in one months time. I bought a voltage reducer by apc the ones that make ups for compters. Now nothing burns out I haven't changed a bulb in at least 3 years. When I go solar I will keep in mind to get a Prue sine wave inverter that only puts out 110 volts I think there is an inverter that has a 105 volt setting I won't use that for motors or or motor driven appliances. Well enough on this.

I actually repaired this same set for my neighbor. One of the led strips was bad. Went to harbor freight and purchased a cheap pair of glass removal suction cups for about $6 to safely remove the led panel as not to bend it. It is very thin and will break easily. Ordered the pair of led strips for about $25 and replaced them. That was all that was wrong with the tv. Neighbor was happy. Only charged him for the parts.

I encourage you complete the repair. I enjoy watching your adventures in repair electronics and your solutions to issues that arise during the process. I learn a lot about electronics and how electronic gadgets work from watching your videos.

I think it's worth trying to fix. If the new LED strips bring the TV back to life, you have yourself a $20 TV. Worst case is that you're out $20. The fact that it's a 1080p TV makes it more worth it, since most 32" sets seem to be 720p these days.

At that moment I was 100% sure was back Light LEDs issue, ordered the LEDs stripes replaced them and problem solved 💜 Also I used 3 9V Batteries to test the complete stripes from the (+ -) test area at the beginning of the stripes and showed me some LEDs were dead, it was a quicker and easier way to do it without his tools (Tester).

Loved the video. Please do this more.

Hours cut so I dug an almost identical one out of the attic. Was told it was probably the backlight. Gives me hope I can get it back working. Thanks for taking the time

This was really, really interesting! Keep up the good work!

This was a fun memory trip. I say if $20 gets you both strips, fix it, then you have two TVs and one spare backlight. You can give the working trash TV away or put in to use elsewhere. Our big Samsung lost a few of the 8 backlight strips and after researching, the best deal I found was a set of '100% good' salvage parts. 37.5% were bad, but it was enough to fix, and have spares. TV is still working great!

I found this hilarious; "I'm sorry for the glare, but this is where I had the remote."

You can replace the individual LEDs instead of the whole strip and it would be cheaper, also if you get to fix it, set the backlight to 80/85% to preserve them. People tend to have the backlight at 100% but 100% drives them hard and will kill them in a short time.

I have 2 TV's over 10 years old I set at 60-80% still going and never had a problem. I just trash picked a 4 year old Samsung 50" from an old lady neighbor of mine that had a bad backlight diode. Just fixed it real cheap. Reak nice clean TV. One thing I noticed is the 2 Samsung's that I have, both 2018 TVs, one is a 50" UHD 4K and the other a 50" 5 series, both default the backlight brightness to 100%. So if you don't know to check it you'll be getting a new TV or a repair in a few years. (2-4).

I'm the curious type that loves this type of challenge. I've saved a ton of money over the years just by investigating. An example: A very expensive Wagner Paint Sprayer. Bought at a home resources center that sells used building supplies. Paid $8.00 Appeared to have been used once and not cleaned properly. I soaked a rag in laquer thinner, wrapped around parts to soften enough to remove. Then soaked and wire and toothbrush cleaned. Sprayed cleaned parts with silicone. Put back together and used it for approximately 5 years. Painted house, fence, bi fold doors, garage overhead door, decks etc. Wagner is known to readily give out if not given pristine cleaning and re silicone moving parts. Idk. Some might have the money to buy for 1x use and toss but not me. I was widowed at a young age and proud, as a female, to have learned so many money saving skills. My uncle taught me many and after he passed I turned to you tube. So, thank you so so much for taking your time to video this great presentation. I will be subscribing and tuning in again.

Interesting video that gives a lot of insight into how modern TVs and led panels work. You can see how these things are designed to be modular and repair usually just involves replacement of larger, but still relatively cheap components. Also, seeing how these are made compared to the price the markup on them seems like it's pretty huge.

@Dutch3DMaster

Жыл бұрын

They are modular, yes, but that's due to the nature of how these panels work. They are not made to be repaired: manufacturers do not like to hand out information on what to look for when troubleshooting them down at part-level. For regular consumers, those relatively cheap components are usually hard to get, and some brands actively discourage consumers from being able to replace parts by not making them available to them, and sometimes have a price-point that is deliberately designed to put people off from buying the replacement part to sway them to buy a new set...

Aw common just fix it already. 😀 You couldn't replace it for 20 bucks but if you don't need another TV them just scrap it for parts. As far as content it's still digital and it did end up in the basement so all good stuff. Thanks for bringing us more diverse videos!

I'm not particularly good with electronics... but after watching some KZread videos on similar TVs... and two hours of fiddling later... I had the new LEDs fitted and nervously switched it on. Nothing. Quick check. I'd forgotten to plug one of the two ribbon connectors from the TCON module to the panel. So that's good news... tried again... and BINGO! It worked. Great sense of achievement. Even if it is a simple fix to experienced types.

It doesn't have a TV receiver built in, so a display with a tv receiver would be worth maybe a little more than $5, say $10. Only thing wrong with it: 2 or 3 pixels don't function.

@Scott Lichtsinn I live in Asheville NC and I bought my $5.00 19 inch diagonal monitor here. 16 inches by 10 inches. It is 1440 x 900 pixels. I'm using it now so I can look up the model number easily. Branded "Envision." Model G918w1. I think it was manufactured around 2008 or so. I seem to recall being able to download the owners manual. I bought it at not-for-profit second-hand shop. Before buying it I was allowed to plug it in to a 120vac outlet to see if the "no signal" legend came on the screen, but not allowed to plug a signal into it to see if the signal got carried all the way through. I knew at least that the backlight was working and some of the pixels were functioning. So I was taking a small risk with my $5. The not for profit company claims that people donate their used stuff to them, they sell the stuff to other people and they use the revenue from those sales to operate a no-kill animal shelter. Yes I was surprised it was only $5. I think Goodwill and Salvation Army are selling similar ones for $20 or $25 leading me to believe I might find one at a yard sale for around $10. I have picked up 2 other flat-screen monitors for free. One from a friend who bought a newer, bigger one, and one from an estate sale.

As he mentions, the aluminium backing is essentially a giant heatsink. Ive tried this before and even flooding with lots of heat it's very very difficult to remove the LED's from the strip. You would also want to source the correct matching LED's because different types will draw different currents and have different voltage drops across them. This could possibly confuse the controller or might end up with different brightness LED's etc. Having said that, I personally would fix the set. $20 isn't too bad.

Fix it by replacing the dead LEDs, it's a common type failure that I've seen a lot and I really would like to find a trick to repair these cheaper.

When I was younger before all these smart TV's came out I used to drink around with fixing transistor radios this was around the 70's When I was no more then 8 or 9 years old. I thought it was kind of fun to Get them working & selling a few in my mom's garage sale.

Thank you it was very interesting and a learning experience for me thanks

Fix it, you can do it!

A warning about power supply current limiting. There's a capacitor across the line after the limiter. This means the LED will get far more current for a split second. You need to be aware of this. The capacitor value can be pretty high in some supplies.

I had this exact experience 2 months ago with a trashpicked Samsung TV that I think looked exactly like this one, even the additional screws for the stand. After determining that it was something blown in the power supply, I just abandoned it and let someone else pick it off my own lawn. Fortunately, they did; more power to them. 💪

Nice troubleshooting, thanks

Assuming the only thing it needs is new LED strips to be functional I think it would be worth the $20 to fix it if you want to use it. As far as content for your channel it is definitely worth fixing.

I think you should fix it.

This is the first time I watch you and I liked.

My colleague used an angle grinder to salvage parts of other strips with the same problem and soldered working LED strip pieces in pace of the broken ones in the TV I use now. Works perfectly.

Looks like $20 worth of satisfaction if it works. I’d give it a try.

Your power supply surely has a capacitor across its output (you see the LEDs flash very brightly at first) This might kill them with the high current

Need some videos dedicated for analog-to-HDMI video output devices designed to facilitate hooking up retro computes to modern digital monitors. There are a number of products on eBay but really no good way for consumers to know what they're getting (and they're not cheap) because amazingly there are no retro computing channels that will bother to take the time to survey these things and review their efficacy and value proposition. This channel, given the technical expertise, is probably the most qualified to actually do such a survey.

Could you not cross connect the leds? I forgot the correct term but they do it with Christmas leds so if one goes it stays on

Great video 👍I fixed few LED TVs with same issue, even though LED should last a long time kinda doesn't because people like bright backlight causing early failure. If customers turn off the lights in the room and keep the backlight to 50% it'll help prolong the backlights. Just my logical guess why it fails.

Fix it. Would love to see it come back from the dead.

Those TVs are great for using as a monitor, those old LCD Samsungs haven't almost any lag on game mode.

That brings me in memory, that i found also a trash-TV (it was a HD-ready Telefunken that also could be Hitachi-labeled) that needed new backlight-LED-Stripes. I've got them from UK, i live in Germany. Flawlessly it has worked and i give it to somebody, that could use it for his holiday-home at the coast of northsea. I prefer good old LOEWE, especially the later models with 1xx and 3xx-Boards.

Usually if it's the leds they will flash but I've never seen one that didn't have a bunch of strips and a few of the leds on some of the strips will go bad so this is a first to me but I've never bothered to repair a small TV. Only reason I know this is because at least the ones I've repaired has had that issue. I'm no professional by far so I am constantly learning new things and this has definitely taught me something. I have learned my lesson on repairing leds though lol. The first few times I replaced just the blown leds and not long after a few more blew. I also had an issue with the first 2 that the globes would fall off and caused spots in and had to take back apart again to fix. Regular superglue doesn't seem to hold them very well lol. I do find it fun to repair them and maybe I'll repair smaller ones now I've watched your video and I'm glad I did because I'd probably just replaced the boards thinking because it didn't flash that leds where fine. Good video thanks. Oh you can replace the leds with either a heat gun or a heating iron. They're actually really easy to replace but I suggest the heating iron which I can't remember name. The strips themselves actually take heat well and it doesn't seem to effect them. You can buy hundreds of leds really cheap but make sure they match. Also I'd use 2 part epoxy for globes and be very careful to place exactly in the correct position because they matter lol. Anyway good luck. I'd like to see you fix it myself.

NEVER REALISED THE BACKLIGHT WAS SO PRIMITIVE

It's shot!part it.

A friend of mine gave me his broken 50 inch Toshiba. It was only 4 years old but off warranty already. After carefully opening it up, I replaced the LED strips (turns out I only needed one) with a kit I got online shipped to me for about $120. Best $120 50 inch TV I bought ;)

@@KaosZ007 Yeah? What brand? Also, how will that help me to learn how to fix something I never got my hands into? Sometimes saving only a little (or outright purchasing spares for more than the book value of what's being fixed) is beneficial in other ways than just the perceived value. The difference here is consumerism vs. tinkering. I would not otherwise buy a 50 inch TV because I use it like, 2 hrs a week, mostly to play Wii with my family. The plasma 42 inch I as a result gave to my dad would have just kept being used by me. The end result is that the TV did not end up in the trash piles in Africa, getting open-fire burned for the traces of precious metals within. My whole channel is about repairing old stuff and selling it. Simply purchasing a new TV would not add value to what I do for fun :P

You're a trooper!!!

This pretty cool. I have a Samsung Tv that isn't working and this as been a good lesson in troubleshooting
