A Professional Manufacturer of Smart Interactive Screens For More Than 10 Years

So this is the first time in more than a year that I 've looked at on Instructure, and to be honest, you'll think I don't need to be able to realize that Gmail filters notifications as spam for so long. Anyhow;
When writing in the UK, I was told that this is not covered by the warranty and that I had to pay 150 to replace the motherboard.
In other countries, Samsung seems to be more benevolent, and since writing some legal proceedings, there have been subtle design flaws that have performed after your warranty expires.
So if you have some kind of psychological argument about the options you can choose, don't turn on the TV first.
Phonesamador, check to see if your model is on this list and get to know the legal situation no matter where you live.
At the time of writing, I also seem to be marginal illiterate, so at some point I will write this article in a way that should be understood.
If you watch this then you may have a broken Samsung TV.
This note is about how to fix one of the most common faults in samsungLCDtvs.
This appliestopretty widerangeof model, but in short, models with piano black borders are all affected (
This is something that can be fixed in this way by those who have problems).
It should click once when you turn on the TV.
The problem is to click more than once.
First two, then 5, then 10, then 50, etc, it actually takes about 10 minutes to open.
Here is how to solve this problem, you need something
Soldering iron (
30 watts or above)2)solder3)
Some corners 4)
Some stitches.
2 screwdriver (
Big and Small)
First of all, unplug all the plugs, especially the power cord.
Turn on the TV once you do.
I haven't forgotten yet, I just said it would help to unplug it and drain some energy from these capacitors. Next step: Wait.
Let it sit for a few minutes and there are some fairly large capacitors in it and once you do that you will not forget that you need to put the TV on a duvet or something soft.
It's better not to put it on the carpet, even if it's soft, because Static electricity is not good for any type of semiconductor, you need to open the case whether it's the screen or the inside of the IC.
Remove all the screws on the back of the case and lift them up.
Be careful when lifting it, if there's anything that feels like it won't go away, check it out and it's easy to miss a screw or two.
Now that it is open, you should see a picture similar to the one below.
If your TV is over 50 inch, then it may not have a metal case on the motherboard, so just screw these cases off.
The beige board is the piece we are looking for. Samsung easily drew a large black line in the middle, indicating which side is alive and which side is slightly less alive.
If you can't distinguish the dangerous side from the non-touching side, the dangerous death sign is on it.
What we want is a cluster of electrolytic capacitors in the corner (
Look at the second picture).
You can tell which ones are dead because the top is bulging and may leak a small amount of black electrolytic fluid.
Four dead on my mine are 10 v, 1000 uf, 108 degree working temperature capacitors.
But other models may be different, so it's worth checking.
Don't try to find the same capacitor online, it's a bit silly. (
Is it smart to replace an already undervalued part with the same underrated part? )
I replaced them with 25 v, 1000 uf, 105 degree capacitors, the capacitors should be the same as the original, but the voltage should be a little higher.
Once you know what they are, you can go out and buy them right away and move on to the next step.
Or you can do what I do, that is buy them online, put the TV back together and click until they arrive.
I bought mine from mappers online store, about 70 p each.
I'm not sure if there are mappers in the US, so I can't really help you there.
Edit: I 've been told since then that radioshack is not the place to wear a hat.
So far you should have shiny new capacitors, whether you buy them from the Internet or from somewhere else.
If, like me, you buy their network and put your TV back together, you need to take it apart again.
Just go back to a few steps and follow these instructions.
Or you can start.
First, we need to remove the Power board, so unplug all the cables and connectors from the Power board (
Take notes if necessary)
Take out all the screws carefully and do not touch the hot side.
Now remove the unreliable ones.
When you melt the solder on the other side, gently pull out the capacitor and once it comes out, put the new solder slot in.
It is important to remember the polarity, and the short legs are on one side marked with a black line.
If you are not sure, then there is a small, marked positive number on the weld side (longer leg)lead.
Weld your new hat and trim the lead sand voila!
Repeat this to all the dead and regroup them together.
Try it once everything comes back together and plugged in.
If it doesn't work then you have a problem. (
You signed a disclaimer, right? ).
Open it and check all the work you do.
Check the polarity of the cap, check the bad joint or solder joint to ensure that each connector is firmly placed back in place.
However, if it does work then: HOORAY it works!
Celebrate by watching TV.
You can go now, you can go. GOHOME! ! ! ! ! ! AAAAAARGH! ! ! ! !
