LCD TV's have a known problem with capacitors going bad. If your Samsung LCD TV won't turn on, or makes repeated clicking sounds, there is a very good chance that you can save hundreds of dollars doing this simple repair yourself.
I know, I know. Are you crazy? This is a repair almost anyone can do. You sit down and get comfortable, ready to watch your favorite TV show or movie. You turn on your TV and Unsure if you hit the power button, you try again But you do notice a clicking sound emanating from your TV. HDTV's aren't cheap. Heck, I'm sure many of you don't savor the idea of spending a few hundred on repairs.
Well, I have bad news and good news. The good news is this repair is actually quite simple, and with only a few basic tools and about 20 bucks, you can have your TV working in less than an hour.
Don't have a Samsung? Read anyway, this guide will help you with any brand of LCD as bad capacitors are very prevalent in modern electronics. It's about 20 bucks. After unplugging everything on the TV, you will need to remove the stand. If your TV was wall mounted you will need to remove the TV from the wall, and remove the mounting bracket from the back of the TV. The TV sits on top and inside the stand, so it wont just flop over when you remove the stand screws, but it's always safer to have a friend hold the TV upright as you remove the screws from the stand.
Then each of you grab a side and carefully lay it flat on a carpeted surface. When handling your TV always keep it straight up like your watching it or laid flat. Any force applied at odd angles can damage the fragile glass front. Remove the 7 different wiring harness located on the circuit board. A simple tug on the connector clip not the wiring should be sufficient to remove them.
Remove the 6 screws shown on the picture above and remove the circuit board from the TV chassis. This board is a power supply board and not particularly sensitive, but it is always a good habit to handle these boards carefully and by the edges.
Usually, but not always, capacitors will show visible signs of failure. There are two main types of visible failure. When it fails, the chemical reaction inside the capacitor can produce hydrogen gas, so capacitors have vents cut into the tops of their aluminum cans.
These are intended to break and release the gas that has built up inside the capacitor. So, a capacitor which has failed can show bulging at the top. Below is an example.
How to Fix a Samsung Smart TV Clicking When Powered
Another sign of a failed capacitor is leaking fluid electrolyte. This can be an orange or brownish discharge from either the top or bottom of the capacitor. Usually, with leaking the capacitor will also be bulging.
But a capacitor can bulge but not leak. Again, we want to emphasize that capacitors do not always show visible signs of failure.Menu Menu. Search Everywhere Threads This forum This thread.

Question of the Week: What's your best advice for someone shopping for a laptop? Click here to ask away!
We we're convinced it was coming from the wall but last night, it seems it maybe from the Sound Bar. We have a Samsung TV and sound bar. We turned the bar off and are going to leave for the weekend. Any idea as to what is happening, we thought we were going mad!! Mar 25, 17, 886, First figure out if it's from the sound bar or not.Visit our Blog to catch up on the latest Community news, tips for your Samsung products and much more!
The Future changes shape! Meet the new Samsung smartphone! Yes we've tried everything Re: cables and sound settings. The issue IS resolved with moving the aerial further away Got a freeview box today to test - sound issues were resolved BUT the picture was compromised and defeats the point of buying the tv on the first place. But only sometimes.
Sometimes turning tv off and on helps, and sometimes cleaning with Smart Manager do the trick. This community forum is great. I had been plagued by the randomness of this problem coming and going and have learnt on here that the source of the problem is perhaps related to the TV aerial input and specifically when the Digital TV source is set to an HD channel.
I have tested by doing both - i removing the Aerial Mine goes through a BT YouView box first before connecting to the onebox - noise goes away and 2 Selecting on Digital TV source a standard channel not HD - noise goes away.
This is a strange fault - but if others can test this to see if we have a consistent reproducable fault, we may have more luck getting Samsung to do something about it. I will continue my testing to see if there is a way to resolve - ie ferrite beads, attenuators, splitters etc. Thanks everyone. Selecting a standard definition channel before using HDMI works for me too. I have reported this issue to Samsung but they are saying that they don't have any known issues relating to this even though I provide them a link to this discussion!
We can probably rule out low quality HDMI cables being the cause, because 2 out of 3 of my HDMI devices don't have cables one's a Chromecast, the other's a FireTV Stick, and both are plugged in directly without the need for extra cables.
For sound I'm using the optical audio output which is connected to an amp via a splitter so that I can also send the sound signal to a separate BlueTooth transmitter. But I've tested it with standard TV Speaker output as well. In both cases I'm getting popping, and if anything it's worse through the TV Speaker.
The sound is flawless when watching standard TV, any of the built-in apps, or anything on an external HDD plugged in to one of the USB ports so far at least. When you notice popping sound try to reset TV without changing TV source: Just press and keep remote power key till Samsung Logo appears. It will last for few seconds, not more. So, Samsung should implement a fast internal reset every time you switch to HDMI source and it will be solved.
I can confirm this is correct. I have ALWAYS had this issue since purchase and have tried multiple resets, viewed so many forums in search of an answer. This fix above has completely sorted my issue!

What kind of tv is it. Brand, model, LCD, etc. Most popping is caused by either a short in the wiring to the speaker system or thermal expansion from the heat generated by the display. In rare circumstances it could be hardware related as with faulty caps or an intermittent short on the PC board somewhere.

It seems to happen in HDR only, meaning the backlight is maxed, combined with the extremely hot weather, I am leaning towards this combination being the cause.
What you're saying makes sense, but sad to say, the sound is still happening which means the new version update isn't working, which means to me that there is a defect with the TV or one of its components. Next step?
Back to Samsung customer service; not looking forward to that interaction. Not sure what software version your tv is on my popping sound was solved with firmware version with QLED. I have the un75mu with the pop and lowered volume. My version is Says it is the current version. Sign In. Turn on suggestions.

Re: Sound pops while watching tv. Reply Loading Thanks, Joe. Version Hopefully a Samsung engineer will read your post and contact you. Fingers crossed Have a good 4th!
SamsungCole Honored Contributor. Did you look up your model on the Samsung site; it'll tell you what's out there for ur set. Related content.It makes no difference weather the volume is higher or lower it still pops, but the intensity of the pop does change with the volume.
Go to Solution. View solution in original post. I searched out here to see if anyone else had the issue and if there was any resolution. I only have the built in TV speaker. One HDMI cord from tv to box. It does not seem to do it all the time. It happened some a couple days ago, I don't remember it happening at all yesterday lots of football all daybut tonight it's doing it on NBC football game; didn't seem to do it all day earlier on other non- NBC channels.
It happens during broadcast and commercials. I will be watching this thread for answers. Sorry that I can not help but i was coming here to ask the exact same question.
Samsung TV Makes Clicking Sound and Won't Turn On
The bose system has never had a popping issue before the new TV. I have a new optical cable coming tomorrow but i sincerly doubt that will fix anything. If Samsung or other users could chime in with possible soltions it would be helpful.
I hope that we all find resolution soon. Did the new optical cable fix the popping issue? I'm wondering if that's the issue. Same issue here. Very random. I would guess a decoder problem which should be easy to fix with software.
