    Ah, I have so much nostalgia of watching TV on of these Samsungs that my grandparents owned. Looks exactly like this one but I'm not sure of the screen size. I used to stay up all night and watch TV on it in one of the rooms all by myself, the powerup sound at 17:19 takes me right back.

    i have a LN40A550P3F samsung lcd tv and it was given to me dead. so for the cost of about 6 bucks i replaced all but the mass storage caps and it has been working fine. this was the 2nd time the power supply went bad, the 1st one was replaced under warranty this one only lasted 3 years so i got a tv for 6 bucks and my time. i only use panasonic, rubycon, nichicon and united-cemicom caps so this will last a good long time. samsung has been using cheep caps in there monitors and tv's since the early 90s late 80s so I don't believe they were miss-labeled. just trying to make a few more bucks! great video!

    I had a similiar samsung but 32" one, it broke just beyond the warranty period. I had ordered a bunch of 1000uF caps from China and they were branded: VENT, what a lucky shot since the old caps vented too lol!

      SOLDer ic the correct pronunciation, one will notice that the first four letters of the first syllable is SOLD.
      Aluminium is also the correct pronunciation.
      the same as Uranium, Sodium, Germanium, Plutonium. Magnesium.
      Originally It was Aluminum, and names in the manner of Platinum,
      Aluminum became preferred in the United States and Canada, while aluminium became favored throughout the rest of the English-speaking world.

    Great job as always. How in the hell do you get 27 thumbs down for fixing your neighbors TV for free. Was it the off brand iron, solder type, or maybe lack of flux. What is wrong with people now days. Few hours ago I watched his air show he recorded back in the 80s .Surprise surprise someone gave a thumbs down to that video. I wish I could really type out the obscene words going threw my head at this very moment. How about everyone who gave this video a thumbs down explain why. Maybe I am missing something because iam so stupid.

    I had to repair my LN40A530 years ago, 7 years ago now. Those caps are simply so cheap and horrible. No wonder Samsung got a class action lawsuit on these sets. Sadly since I fixed it myself I was ineligible to be refunded the money for the parts. This being after the tech they sent wanted to charge me money.

      That one came from crappy tire. The bulb burned out after a few months. Went and bought another to get the bulb out if because they did not stock the bulb. New bulb lasted only a few months. Nobody carries it. I tossed it behind the monitor on the bench but don't hold my breath that I will find another bulb.

I jsut dont have any video on panel and sound , for the moment , ill donate some for the advice

    Hi 12voltxids. Thanks for taking the time to make this video, I find them very helpful, what I have seen a lot is caps on lines that are more than 10, 16 and 25 volts have the wrong voltage, usually far too low a voltage caps in them, I think it so as they go bad sooner and you if you didn't know might either by a new board or another TV set, so as you do always replace them with a higher voltage cap and it works for longer, but why do you think they are using the incorrect voltage caps, I would like your take on it, it was you that inspired me to start fixing mainly TV's and your videos are truly great, love watching you fixing them, keep up the great work as it's always good information. 👍

    I have one of those ONKYO receivers. Tx-nr818. Had it fixed with the extended warranty. Had a power surge last week and completely fried a surge protector. Now the receiver has no audio or hdmi video again. Also took out my JVC DLA-rs1 projector. So they said that was a one time deal and that I can take it to a onkyo repair center or Best Buy. Guess that is not free?

  • @1959Berre
    @1959Berre 6 лет назад

    Caps can fail in many different ways. Obviously, capacitance may drift. Elco's tend to rise capacitance as they age and dry. Another parameter is ESR. A cap reading fine on ESR may still be bad when operating under load. Leakage (not stuff dripping out but electric leakage) should be tested with a leakage meter. ESR test is just one test.

    • @12voltvids
      @12voltvids  6 лет назад

      1959Berre
      Duh. If you watch the video for the technics tuner that had no display you will find that the fault was a cap that went electrical leaky. They need to be tested for capacity, shorts and esr, however esr going up is the most common fault and it will show bad long before the capacitor shows any other signs of fault.

    @fulwell1 7 лет назад

    Here's a daft question for you - the LED backlights on these modern sets, what sort of voltage/current do they run at, just purely to light the LEDs? I have a scrapper sitting next to me at the moment (kids destroyed the main board by hauling on HDMI plugs, which in turn hauled the sockets off the board and tore traces off the board with them - and it is a crappy Vestel thing, so BER), and I am toying with the idea of gutting the chassis out, and building a suitable power supply to run just the LED's as a light box?

    • @12voltvids
      @12voltvids  7 лет назад +1

      The LED lights are all connected in series.
      I did scrap a set with a broken panel a few years ago. The panel had LED strips that had a plug in the middle so basically 2 strips joined together for the width of the panel. Each strip ran on 24 volts, so 2 of them together was 48 volts. The TV had 2 main strips connected in series, and the power supply was feeding 96 volts in. There was a total of 4 full width rows of LEDs so 8 24 volt strips. I believe I did a video showing where I rewired the 24 volt strips to 12 volt strips, and I have 3 of them in my stereo cabinet to light my turn table up.
      Some TVs they have 192 volt supplies now. All the LEDS are in series, so if 1 LED fails the entire backlight goes out.

    • @fulwell1
      @fulwell1 7 лет назад +1

      Oooh, interesting! I might be best to use the separate modules to make four separate, switchable lights - might be interesting in our gazebo..... thanks :). I will have to wait until the owner decides on its ultimate fate.

    As for power consumption. Exactly. Of my five TVs two of which are Plasma, The Yamaha, branded 42' [Hitachi Chassis] is only consuming 180 Watts ... and the 65" 4K LCD is consuming 200 Watts.
    Thus Plasma TVs are not necessarily more expensive to operate, as you stated.

    • @12voltvids
      @12voltvids  7 лет назад

      That circuit glue can cause many problems. It is horrible stuff, and needs to go. I just did a video on an NAD preamp where circuit glue was causing terrible audio bleed through on the tape monitor mode.
      Not only does it become conductive, it also becomes corrosive and will eat through the solder mask, and attack the copper under it eventually causing an open just like leaking capacitors do.

    Same way as goes to Samsung's Computer LCD Monitor that had a notorious cheap capacitors from China that never last long, and we all know that Samsung will continue to repair customer's LCD HDTV and LCD computer monitor as long it's cover with warranty, but there's no guarantee where it can be service to change to a new one.
    For me, I really don't really have to take it down to the official manufacture and change to a new parts for the electronics and get it going again because, I think they are still stick with the either a generic or knock-off Electrolytic caps where they can't afford to replace with the genuine Electrolytic caps for the electronics to hold much longer.
    I do replace with the actual Electrolytic caps like the genuine products from USA and from Japan which it's real adequate quality to keep it going again.
    I am not sure the circuit glue is similar to wood glue where they place on each components where it doesn't allow to get damage while shipping its product. And we know the circuit glue should NEVER be used in the first place ever.

    I took the back off everything seems to be normal I don't see any Burns or any bulges I do hear a faint humming sound coming from the power board I think it's normal
    It has an error code 2 long blinks 5 short

      @12voltvids  5 лет назад +1

      If you are connected by HDMI, try connecting it using a component cable.
      There were many compatibility problems with Samsung, Panasonic and Sony on their pre 2012 that caused loss of sound over HDMI. Also check to see if the port you are plugged into is marked HDMI/DVI. If so try moving it to an HDMI only port. Those early ports that supported HDMI and DVI sometimes flip to DVI mode. DVI was a computer video interface (digital visual interface) and did not support sound HDMI on the other hand Hybrid Digital Multimedia Interface.
      Some people think HDMI stands for High Definition Multimedia Interface, but that is incorrect, because it supports multiple formats.

    Ah yes: another masterpiece from the 'Land of the Burritos'. So if that glue breaks down and goes conductive, why even use it? Even hot glue can go onto printed circuit boards; why not just use that?

    • @12voltvids
      @12voltvids  5 лет назад

      Certain types of adhesives have broken down and become problematic over the years. As to the type of glue used, they have to use approved types. Has to have specific properties such as low VOC, fire resistant ECT. Just like for cabling. There are specific types for different applications such as plenium wire which has insulation and jackets that does not burn or if it is in a flame condition, does not off gas toxic fines ECT. Since this glue took years to break down, by the time it did there were millions of units in use.

    • @12voltvids
      @12voltvids  6 лет назад

      They did not use it expecting this to happen. Remember that it took years for it to break down and start causing problem. By the time units started failing in numbers millions of units had been made. There were several companies that made circuit glue and many were affected. Remember that companies were limited to what then can put in. It all has to be fire rated for safety and many of these problems were caused by compounds to make them fire resistant. Moat of the time it was a rubber based adhesive and well rubber decomposes over time.
