2 COMMON WAYS TO FIX SAMSUNG TV CLICKING ON OFF TUTORIAL GUIDE

Note: act at your own risk working on electronics, shock hazards even when unplugged..

4+ year old video and you're still helping fellas like me out! ordered the capacitors off Amazon, followed your instruction and fixed my TV for $6.03. Thanks very much Tampatc!

These how to videos are awesome!!! Now, as an electronics engineer with over 30 years experience in several industries including consumer video electronics, I’ll point out a very key missing point regarding the caps. The failure mode is outgassing due to overheating hence the swelling and bulging - no surprise as most know. And, true, replacement caps are easily available. But here’s what I want everyone to know and it is not being mentioned on these how to sites. The problem with the caps as you might imagine are that they are cheap, Chinese supplier go figure. The reason these caps overheat is they are as this video explains, are used to filter fluctuations on switching power supplies. so what occurs is what we call ripple currents. I will simplify Ohm’s Law by restating that voltage equals current times resistance, but what is that play in these failures is the fact that there are time varying currents i.e., the ripple currents flowing continuously through the capacitors
due to the switching mode operation of the power supplies. so, now the problem with this. no electrical component has ideal properties in the real world. let’s keep it to the discussion of capacitors. capacitors have what’s called equivalent series resistance. as with the operation of space heaters we know that resistance with current flooring through it will result in heat. so overtime this ripple current flowing through the parasitic ESR of the capacitors will continuously generate heat which in turn causes the electrolytic material to outgas and eventually bulges the capacitor and it loses its capacitance characteristics. in the complement industry for electro lytic capacitors there are specialize capacitors they cost a bit more but they have very low ESR. in safety critical applications Mike automotive and dustrial and avionics it is absolutely important to select low ESR electrolytic capacitors.

so, after seeing these how to saying go out and get replacement capacitors I have waited long enough to hear someone mention that the selection should be to get low ESR electrolytic capacitors. to put it in real terms I repaired our Sam song back in 2009 with low ESR electrolytic capacitors and have not had a problem since. A friend of mine did he is independent of consulting me and he had to go back in and replace them after about three years. by that time I got wind of his reoccurrence and got him some low ESR electrolytic capacitors. so my suggestion to the creators of all how to videos for this problem is to please guide people toward low ESR electrolytic capacitors and not just a garden-variety replacement. good luck off.

You saved me 1, 000 bucks. My better half was all set to buy a 60 inch Sony before I fixed our 52" for $5 in capacitors. Well done, good job.

Awesome set of videos- Very easy to follow and I sorted my 44" TV that had been sat in my garage for a year. Cost me 59 pence for a new 1000uF capacitor and 40 minutes work. Awesome. Cannot thank you enough.Just awesome.

Sub'd..great video. I have electronic s tech degree that I never get to use and live in an upper scale apartment complex where people just leave their TV's by the dumpster if they either move or have an issue with them. I think I'm up to around 4 TV's so far this year. The latest has this same issue.

Your video is the BOMB. I bought a small kit that had a plethora of capacitors.I replaced 2 defective capacitors. Put TV back cover on, works perfect.Thank you for the very informative video.

excellent job showing what your doing and what the problems can be. And please don't be mad about Samsung and capacitors, most do not have this problem, and many don't have it for a very long time. Plus its easy to fix. I've had my current tv for a good 5+ years, and only recently has it had this problem, and currently its an easy problem because without even replacing stuff you can simply blow a hair dryer in the vent of the tv to heat up the capacitors fast for the tv to work fine, The more capacitors that fail the longer the tv clicks/to warm up and come on. If you know of a local repair shop you can just take the board to them they can soder in/out new capacitors for cheap.

Hi mate it's good to see your videos again, it's a while since I repaired plasma tvs and it's great to get a refresh on doing it again, so thanks a million for your videos and great work and help. 👍

[chrissyusa]

Really great and informative video! I woke up to my tv clicking on and off. I was able to sort it out, at least for now, by unplugging it for a couple minutes. Still, I wanted to see if this is a common issue and plan ahead just in case. Thanks so much for a how-to that isn’t obnoxious, overly technical or boring.

[DizzzyKipper]

I love all your repair stuff.I archive you and a couple of others.It is a great reference for trouble shooting.
Thank you.

Thank you for this very helpful video. I’m not very handy when it comes to things like this. But I’m going to give it a try. I just had one question that I’m hoping you could answer that may narrow down the cause of my on/off issue. My set does not click on/off immediately. I’ve been timing it and it seems to turn off than back on every 4-5 minutes. In your experience does that lead you to think it’s one issue over another? Thanks again for your helpful video!

THANK Your video helped me fix my Samsung Plasma TV after a power surge. Your instructions - especially testing the standby voltage - helped me isolate the problem to the main logic board with all the inputs. Found part for $80 on ebay, installed it, and our television is now working like before! GREAT VIDEO!

Thank you for this helpful tutorial. I'm having this exact problem with a Samsung TV right now. I'll try changing the capacitors first.

[davidsonmg]

Great video! No drinks near the electronics!!

[Unlockingparadoxes]

Thank you for what you do and everything you have done and your contribution to YouTube and thank you for sharing your knowledge.

[rayfrancis]

Love your videos Sir all information with no bull

[xaviermartin]

video was great so I have 1 question you know sometimes you can go back with a capacitor that is larger than the one that comes out. how do you decide what is to large for that capacitor before it starts to damage the board?thanks

[OneLoveRecordings]

I found a quick fix that helps for a short period and thats to hold down the power on button on the tv for about 12-15 seconds and it will boot into shop mode.

[CSSIandAssociate]

Tampatec very much enjoy your vids. I have a Samsung TV 50" I think it is 50". I will not be using it as a tv. The black screen was broken. The tv was left here when we bought the house. I took out the black screen and will be using it as a light for my electronics bench in the garage. It turns on and in about 15 seconds it will turn off. Would this be the same issue you described in the video?

Any help would be great.

Oh it does not power on and off. When I turn it on in 15 seconds it turns off.

the IC your looking at arround @4:10 is the flash storage. that shouldnt be hot, if so, some datalines or the powerplanes are bad. what might be misleading is that commonly with these board is that they will have had a sticker on the flashrom, nand or eeproms to note wich version they istalled. due to age and surrounding heat, the glue will nolonger work and the actual paper will seperate from the glue. leaving a nasty looking nand/flash chip, but maybe perfectly working

Yeah, if the boards dead, replacing it would be the quickest and easiest way. if the cpu/SoC is dead, yeah then the nand wont be read and nothing apears on the screen ;)
