Samsung TV won't turn on + blinking red light (explained fix) #18

WARNING! Televisions contain high voltage electricity! For safety reasons, only qualified individuals should attempt the procedure shown!
(CC) (HD) A step-by-step repair video, showing the replacement of swollen/shorted electrolytic capacitors in my Samsung LCD TV. "Sped-up" sequences show relevant information to you, while at the same time providing detailed information.
Note! When I say I "zero" the high voltage capacitors, I'm saying I physically "short-out" the 2 metal legs that come out of each high voltage capacitor (labeled as 50 volts or greater) using the metal blade of a screw driver with hands ONLY touching the insulated screwdriver handle, and not the television chassis. This step brings the potential hazard of any possible residual high voltage being present down to a safe value of zero volts. This step removes the threat of receiving an electric shock from those capacitors if human skin makes contact across the capacitor legs, or connected associated circuits.

My Samsung TV would not turn on. It would just make a continuous clicking sound until I unplugged it.

UPDATE : As of now ( March 27th 2023), over 8 1/2 years after this video was made, this tv in the video is still used daily, and still working perfectly!

My TV is a Samsung 46" 120 hz LCD.
Model # LN46A650A1FXZC

The power supply electrolytic capacitors that were blown up in mine were
10 volt 1000 microfarad (blown)
25 volt 1000 microfarad (possibly ok)

I purchased all 4 capacitors at "Sayal Electronics" for $3 TOTAL cost!

Today is August 12th 2018. (Almost 4 years since I did this video). My Samsung television that I repaired in this video is still working absolutely perfectly. I just wanted to update you guys.

Found your video 2 weeks ago. I thought, "What the heck" & gave it a try as the TV was pretty old. Well, the only problem I had was finding a supplier BUT, , the results were the same. Spent $7 on a used soldering iron 80 cents for the capacitors. Only two glitches..1. Lost some fastener screws 2. $11 for shipping. Other then that Im back in business!! THANK YOU

[viperord]

Thanks for the great video.... I was able to repair for $5. Fry's electronics had the capacitors I needed. Special Kudos for pointing out the Zeroing of the high voltage capacitors. Several other videos show the process, but your tips on marking the board and wicking the solder are the fine points needed for success.

Thanks for this, I fixed my tv using your excellent tutorial (which is much clearer and easier to follow then many others I might add). I had newer done anything like this before and I have like soldered once 15 years ago in school ;)

I was this close to buying a new tv for like 800$, but then I thought "screw it, if I brake it even more, it will still be as broken as before". Cost me 2$ in spares + a roll of soldering stuff.

Samsung and other electronic manufacturers just want us to buy more expensive stuff from them, so they put in shit that brakes after a few years.

Thanks again for doing what you do, keep up the good work!

THANK YOU SO MUCH FOR THIS VIDEO!!!! I had to buy 2 25v capacitors which totaled $5! I already had the Solder Wick and the Solder gun. I bought this TV for $30 from someone who said it worked, but upon investigation found out that was not true. Anyway it works PERFECT now! $35 TV for me!!! Whhhoooo So Happy!!

[trinitodebone]

This is absolutely the most sensible and productive video, I have watched on YouTube regarding fixing Samsung TV issues. The info surpasses all help websites and with that I thank you with all of my heart. Well done,

[r.l.]

Hi Mr. Simple Fix. At the beginning of the pandemic, my TV experienced this issue and wouldn’t turn back on. My spouse purchased the right capacitors last weekend and fixed it just this evening. It worked perfectly!

I wanted to let you know that your video saved us a ton of money and we truly thank you for your time. Happy holidays!

[josephvelasco]

Thanks "Mysimplefix" I followed your clear and detailed instructions and in no time Samsung 55" LED TV is back to life. I spent a total cost of $13.61 and saves a ton for a simple fix. Thanks again for uploading this video.

[christinaarmada]

Seriously... This happened to my tv- the hubs went to radio shack and bought $7 worth of capacitors and we fixed our TV. Saved us a ton of money. Thanks for posting!

VERY GOOD explanation of the repair. I am doing this very soon to my 50 inch Samsung. Samsung has been had a BIG problem with these capacitors...it could be a quality control issue or a controlled replacement issue that got away from them. They do not want to spend the additional 35 cents it would cost to install the correct capacitors because the tv would last you a long time. They want to build in a breakdown so you replace it with a new one but looking at how many there have been and the court cases they have lost, it might have been a poor decision. You can now buy a 70 inch tv cheaper than I paid for this 50 inch in 2009 so many do not have the time or skills or patience to repair the unit so they buy a new one. The only problem this creates for Samsung is that the consumer might not want to buy another SAMSUNG that they spent $1200.00 on when they bought it. I still have some tv's that are 25 years old that work fine...only paid $300 for those when a purchased those new. Anyway...this is my opinion on the whole issue...awesome video...thanks for your time.

Excellent video and very clear explanation. I had the blinking red light of doom on my Samsung 40" LCD television, and it turned out to be both 25V 1000uF capacitors that had blown. £1.50 and a trip to Maplin later, and it's all working perfectly again now, and saved me well over a £100 in a repair bill. It's just my wife I've got to placate now as she fancied a new TV for the New Year !!! Thanks once again for the info.

[Skracken]

One of my coworkers was gonna throw one of these away because it wouldn't start up, just like this one. I asked if I could have it instead, which he agreed to. I had a strong feeling it would be faulty caps. As soon as I got it home I took it apart before even trying to plug it in, and found those exact same two capacitors bulging. I didn't have any exact replacements, so I put the closest ones I had at home in there, and that fixed it. It's like it's engineered to fail.... But at least I got a nice big bedroom TV now, for free. :)

Dear MSF, a few days ago I got the same problem with my Samsung 46"-TV, so I started searching for solutions on the web and at a certain point I found your video. What you describe helped to solve my problem 100%. So thank you very much for sharing your instructions.
I wish you all the best for the upcoming 2017 and best regards from Italy!!! ANdrea

[regiechen]

Man its been 5 years since u post this, but it really is helpful i was able to fix our samsung tv today. Im from philippines, salute to u man million thanks! 😁

[Ocullan]

Thanks! Your video saved me a lot of money & trouble, just replaced 4 capacitors and no more startup problems. Had to make second run to Microcenter for a higher temp soldering iron in order to remove old solder.

[dashcamdad]

Thank you so much for this video! Our Samsung TV that we bought in 2008 suddenly stopped switching on, flashing the red light like you showed. Took it apart and the inside of my TV was exactly the same as yours and the same 2 capacitors had blown! Replaced them as per your instructions for a very small nominal amount and the TV is working perfectly again. Again, thank you so much as I wasn't willing to spend hundreds of £££'s buying a new one. 👍

[kkalahiki]

Thanks so much for this video. I hadn't touched a soldering iron since high school but after a little bit of work I managed to get the busted capacitors out and get the new ones in. I had a functional TV again in about an hour. Everything I needed to know was right here in this video. So thanks again. You rock.

[MrVgrao]

My Samsung TV model: LA26A450C1 had the similar problem. I replaced the swollen capacitors and the TV started working. Thanks a lot for posting this Video. It's very helpful.

[jependergrast]

Excellent job! I watched the video twice then made the repair for a friend of mine. Next time, my son get's to do the repair - great teaching tool.

[greenhalghrobert]

thank you so much. Mines been doing the same thing for a yr now. I have a Samsung model #ln-t5271f. I didn't want to just throw it away as its the first tv I didn't get buyers remorse over. For a price tag of just a little over three thousand you would think they would use better parts. Funny, but every repair shop I called and described what was happening, EVERY SINGLE ONE told me they would look at it but it was most likely the main board and the tv probably wasn't worth fixing. With how common this problem seems to be you would think at least one would have heard of it... Very professional video-Great job!
