[Solved] Samsung TV Screen Stains & Dim Spots: Service, Repair Costs, Dust Issues (Photos Included)

Hello, I'm going to call the TV service tomorrow, but I don't know if it makes sense. I want to call because on my samsung TV there were stains on the right and left sides of the screen and from the bottom and top in the center of the screen there is a small, poorly lit space and it looks different than the stains that appeared. Give this TV to the service? How much would a possible repair cost?

I am attaching photos which, however, do not fully reflect the actual condition of the TV because these stripes and rainbow on the screen are not present. I took pictures with my phone and camera and these stripes always appear when taking a picture. I mean whether these stains can be cleaned because I read that it could be dust collecting on the TV. The TV is no longer under warranty. I cleaned the screen and it cannot be cleaned from the outside.

Stains can be the result of dust. Unfortunately, today's dies are not tight. Unfortunately, these may be so-called "pressure marks", which come from external pressure or internal stresses in the housing. In the second case, I do not see a chance for repair (unless by replacing the matrix), in the first I dare to doubt whether a service will undertake this cleaning. This dust is very difficult to remove from certain layers of the matrix unit.

2 or 3 days ago there was an identical topic. And there are dozens of similar ones, and nobody reads them, they just start a new one right away ... Sad that that work and advice are wasted.

The screen is dusty on the inside, but that's not all. The backlight is already worn out, which is manifested by blue spots.
As for the costs, it depends on what price the service will get a complete LED backlight. I know from my own experience that the original set from the official source is ridiculously expensive.

There are no blue spots, this TV set is just like that in the pictures. Only in the upper right corner almost invisible purple color.
I will call you tomorrow, I will ask if the repair of all this does not cost me more than PLN 200-300, I think it is worth fixing.
I was going to turn this TV on myself and try to clean it, but I'd rather have it serviced than break it even more.
I wanted to do this cleaning as it is shown in the video:

How old is the TV set?

The TV is 5 years old.

How to switch TV to analog TV? I do not have a TV antenna connected and a decoder. I use the TV only via a computer, connected to the graphics card with the HDMI cable.

Press the "Source" button on the remote control and select TV. The antenna may not be there, so a friend wrote "post a picture of the screen with snow" ...

I chose TV and it says in the frame: Weak or no signal: Check the antenna cable connection and saved channels.

I have looked through the settings and I can't find anything like analog TV in them.

When you enter the channel search option, you will have the choice of analog. ; terrestrial and probably cable - put it on analog and turn on start. The TV will find nothing and you will have a glowing screen with the so-called snow.

There is no such thing as searching and blue screen all the time.

Each TV has an option to search for programs, unless it's a tube TV with a mechanical channel switch. But this is not the case here.
After all, somehow the TV must find TV programs when you connect it to the antenna ... It will not do it by itself, it is done by a human by selecting the appropriate command from the menu on the screen.

It is in the options in the menu that should be blue screen on-off.

You had to set up a manual search, not an automatic one. Anyway, this snow does not look like the picture. It is black and white and in the photo it turned out blue.

You did not write what the screen size is, because the price will also depend on it, the smaller the cheaper. Cleaning will improve the image, but it is not always perfect. After disassembling the panel, you can assess the quality of LED lighting (not to be confused with their durability).

I gave the TV to the service and I was told that 3 LEDs are burnt and the others are in bad condition, which is why these stains are present. For cleaning and replacing all the LEDs, they asked for PLN 200 along with the labor.

If over 32 "is inexpensive, but it is best if they put new slats on you, then you have peace of mind for a longer time.

40 inches has a TV: https://mediamarkt.pl/rtv-i-telewizory/telewizor-samsung-ue40h5000aw

I don't know, as long as there are no stains after replacing the LEDs, cleaning and that the TV works as it should.

If they clean you and give you new LEDs, the TV will of course work, there may be some delicate spots because the TV is a few years old but they will be acceptable, while the LEDs are connected in series-parallel and it may turn out that the old ones, not replaced, will fall in some time / you just don't know when/.

All diodes will be replaced, not only the burnt ones, because the unburned ones are also of poor quality.

If as you write, you have a chance for a reliable repair.

That's good

Something is suspiciously not enough (PLN 200) for new strips to be installed. The new set of LED strips for 40-inch TV costs more.

That's what they told me that PLN 200 for cleaning the TV and replacing all LEDs. How much does a new set of LED strips for a 40 inch TV cost?

Very little, replacement of all LEDs (soldering) takes a few hours, and not everyone can do it well. Replacing them with new strips means the cost of the parts will be higher.

Recently, I was buying a new set for a 32-inch TV and I paid about PLN 150, for a 40-inch TV the price is definitely higher. All the time it is about NEW straps, not the demolition of several-year-old TV sets.

I picked up the TV and it turns out that only 1 stain was from dust in the lower left corner and the rest appeared through burnt LEDs. The LEDs have all been replaced and the dust stain has been cleaned. I paid 200 zlotys and after connecting the TV I find it was worth it because there is no trace of the stains. Regards and thanks for your help.
