New POST TO AN OLD VIDEO (Oct 2019): These failures are super common and based on the failures I would replace the capacitors with the next higher voltage value (NOT A DIFFERENT UF VALUE) For example if 2200uf 10V failed replace with a 2200uf 16V. 16V=>25v 25V=>35V 35V=>50V you get the point These caps are known to be under rated for the purpose. which is why the problem is so wide spread. Most of these TVs can be fixed for under $20 There are a few power supplies with cracked solder joints on some components. A close inspection with a magnifying glass can help you find them. To fix just reheat and add some fresh solder. A guy could make a small fortune finding these TVs for free and fix and turn around and sell for a few bucks. ******WARNING******* There is 1 Capacitor rated at several hundred volts, this can cause injury if it is still holding a large charge. Test with a meter and discharge through a large resistor if need be. The capacitor is the huge one and very obvious. Take these precautions seriously. Cheers
Manufacturers of electrolytic capacitors specify the design lifetime at the maximum rated ambient temperature, usually 105°C. This design lifetime can vary from as little as one or two thousand hours, to ten thousand hours or more. So if your smart TV, or Electronic Controlled Refrigerator fails to turn on, then before replacing it, check the Electrolytic Capacitors. They are big enough to be checked and replaced easily. Make sure to replace with a top quality capacitor with identical specification.
I have this issue with my '07 Samsung 40'. Good tip. Not the best soldering job. Use solder flux and clean it off with rubbing alcohol after you solder the joints. Don't let the solder touch the other traces and use just enough solder to get the job done.
Thanks! This save me hundreds of dollars by avoiding buying a new TV! Cost was 1.99 from Radio Shack for 1 new capacitor (35V 1000uF). Although they only had Caps rated for 85°C instead of the 105°C that the old one was rated at. We will see if it holds up.
Just fixed my 42" tv amazingly easy fix....Almost cost me $600.for new tv 55" but the fix's was $17.95 for the Capacitor kit.....Had to change out 8 Capacitor.........
I have an lg and had to replace the power board, before putting on the back. I drilled numerous holes in the back panel to allow more air to circulate. I believed it helped. per tech folks the capacitors are under size
On the side of the capacitor it will tell you a voltage and capacitance. So, on my tv, 3 were blown. On the side of 1 was 35 V, 1500 μF (micro farad, be careful not to mix up nF with μF). So when looking for a replacement I look for one with 35 V and 1500 μF capacitance. Also take note of the height, diameter and lead pitch (how far apart the leads are). You don't want to get one that won't fit.
Tumatauenga what about diameter of the capacitor? from the pics on amazon the one I need looks shorter and thicker. The one on the main board looks skinnier and taller. Any advice? Does it not matter?
I have an old Sony TV and found a blown capacitor with amber goo flowing out of the top of it (now dry). I suppose that explains my problem! I will try to replace it and see how it goes. Part of your video is barely audible, fyi. Wish it was ... seems important.
I just fixed my Samsung Monitor this way thanks to this Vid. I hadnt soldered in 30 years, went to Radio shack and got the capacitors($2.00 apiece) and fixed it in minutes.
I'm using a 15v. soldering iron and it doesn't seem to be strong enough to melt the original solder. What voltage iron is the best to use without damaging the board?
is this still the same instructions on a 2012 mode? I have a PN64E7000 with this issue, the red light flashed about 6 times I the picture never comes up.
Could you explain please, I'm new to this and I need to fix my toes capacitors. I had no idea it was dangerous to replace them, you could send me a video too, are they lethal if the TV is still plugged in or are they lethal even without it plugged in? Thanks
Thank you for your video. While my Samsung has the symptoms of having a blown capacitor or two, visual inspection indicates no mushrooming. Could it actually be the power supply that is causing my tv to cycle on and off repeatedly upon first turning it on?
They can still be leaking even though they are not bulging, using stuff on Standbye shortens its working life as the Power supplies are in use even if it is on Standbye 24/7 for some people.
Ever hear of one of these capacitors healing themselves? I noticed one bulging in my Sammy Tv (a year ago) and I've been meaning to replace it. Opened the TV up today (was about to take the board out to take it to radio shack) and the bulge was gone. I even scratched/marked the capacitor a year ago so I wouldnt forget. Plugged TV in for the heck of it, it now works. Think it'll last? Strange.
You have to look at the board and see which ones are blown. Mine is the CM807 capacitor. I'm going to replace it this weekend and see if that is the problem. It's the only capacitor that's blown.
I was going to throw an old AIWA lcd tv but decided to play with it and got a TV for the room after changing a few capacitors. I think it's a common problem for lcd tv's and as inexpensive TV's nowadays not a lot of people fixes their own set. I look online for people who throws their tv's and try to fix them for people with no flat screens.
Martijn Rentema how do I know what to replace the capacitor with? There’s a number on the board and then the actual capacitor has some numbers on it. No luck in my search online. Any advice?
hi, after searching forever i saw that you have the same exact model that i do. if u ever get this can you walk me through a vid or email. My same exact model wont turn on, i tried unplugging it to a different outlet, still wouldnt work. I'm not sure if it's a short circuitage, shortage, main circuit board or some capacitors. just wont turn on at all. Now i think about it it was probably plugging to much cords to a power strip, but thought power strips were made for that exact reason, to avoid shortages/ circuitage. HELP PLEASE! i dont want to loose this TV!
That's what mine was too. It took a looong time time to melt that soldier. Just go to Amazon and get a bigger one if you're going to do much more of this stuff. They're pretty cheap.
Richard Dapice I haven't made a capacitor replacement tutorial yet... and what I was saying is that this video isn't really that helpful because he didn't cover esr, capacitance,voltage and quality ect !!
its 2019 and I just got one of these tvs for free and this is the problem. after hours online I found your video and I know I can do this myself. lol 80 minimum my ass tv repair place. subbed for sure. are the capacitors in this spot all the same? my tv is a 55" and not sure what caps to buy
i actually got into the habit of turning on my tv and then doing something else before watching. my tv takes 40 minutes of clicking to turn on. im in the process of replacing the capacitors. i opened the back and what do you know all 4 were blown.
I was having the same problem. It was getting up to 10 minutes - REALLY. Contacted Samsung and they had a contractor out the next day and fixed it for free. He replaced all of the capacitors. I have a LNT 4061 that I purchased in 2008. I believe their might be a class action lawsuit.
There's no fucking way i can get through doing that without fucking up my TV even worse... He lost me when he presumed that i should know how to use a soldering iron smh
Just buy a better iron than the one he shows at the beginning, check Ben Heck's tutorials (or any one of the thousands on RU-vid) and you can do this like a champ!
my samsung tv is out of warrenty so i got my tv to come on a much easier way i ran an hair dryer over the back of the tv for 5 minutes and hey guess what it came on
