Question about Samsung HP-S4233 42 in. Plasma Television

1 Answer

Pixel Problem I looks as though the pixels are messed up. We had a diagnostic done on it and they said it looks like we have to replace the motherboard. The picture does not show although the t.v turns on. It's hard to explain. I was wondering if anyone knows where to find a motherboard for the t.v. Would you suggest I try to repair it myself?

Getting a black spot on one corner of picture. Any suggestions why this is happening?


It is not unusual for a camera's sensor to have a pixel fail this way. Most sensors consist of 100's of thousands or more pixels that make up the sensor. Each responds to the color and intensity of the light projected upon it by the lens. It sounds like a pixel on your sensor has failed and is "dead" or "stuck" in a dark state. Pixels can fail "hot" on a single color, too.

The bad news is that it is not possible to fix a stuck pixel. The sensor itself is the smallest replaceable part and is often times not worth the expense of replacing. Compare costs of replacing the part vs the cost of replacing the camera and decide which way to go to be sure.

I did see some Minolta specific info that you might want to look at first here.

The good news is that there is software that will allow you to mask the pixel. Google search for "stuck pixel software" for a list of results. The software analyzes the pixels around the non-functioning pixel, and makes it a color that is far less likely to be noticed. Other software may perform functions that restore functionality to the pixel and others still that do something else. I am unsure of how well the former methods work or how long they might work. Software that changes the output file is the type I used and it seemed to work well. Each file needed to be run thru the software to make the change however.

Good luck!

How to fix a dead or stuck pixel on an LCD screen


A dead or stuck pixel on an LCD screen or TFT can be incredibly annoying. You'll be staring at it for days on end, wondering for how long you'll be without your screen or maybe your entire laptop if you decided to turn it in for repair or replacement. All that grieve over something as unimportant, yet highly irritating as a malfunctioning pixel.<br /> Before you run the item back to the store though, you should try to see whether you can fix it yourself! This, if done carefully, will not hamper your warranty and might save you a lot of time and worries. So let's see what you can do yourself.<br /> Let me say that any new LCD or TFT monitor should be tested for pixel errors. This can be done simply by running it through a palette of basic colors and black and white in full screen mode. The software, which we'll get to in a second, can do that.<br /> First let me explain what you may be seeing. Is it just a stuck pixel or is it in fact dead? A stuck pixel will appear in any of the colors that its three subpixels (red, green and blue) can form, depending on their functionality and brightness. In a dead pixel all subpixels are permanently off, which will make the pixel appear black. This may result from a broken transistor, in rare cases however even a black pixel may just be stuck. So if you're seeing a colored or white pixel, your chances are pretty good and if it's black, there is still hope.<br /> Let's turn to the software now. If you're not on Windows, scroll down for some online tools!<br /> <b><a href="http://udpix.free.fr/">UDPixel</a> (Windows)</b> I recommend UDPixel to quickly identify and fix pixels using a single tool. The program requires .NET Framework 2.<br /> <p><img src="fixpixel02.png" /> With the dead pixel locator on the left you can easily detect any screen irregularity that may have escaped your vision until now. Should you have identified a suspicious pixel, switch to the undead pixel option, create sufficient amounts of flash windows (one per stuck pixel) and hit start. You can drag the tiny flashing windows to where you found the pixel in question. Let it run for a while and eventually change the flash interval.<br /> <b><a href="http://flexcode.org/lcd.html">LCD</a> (online)</b> This is one tool that lets you find and eventually fix stuck pixels. It packs many options into a singly tiny window, but once you have an overview it's straightforward and easy to use.<br /> <p><img src="fixpixel06.png" /> To test the screen click the small 'pick a color' box. The colors you should test are red, green and blue. Additionally you should test white and black. Follow the instructions in the box to gain the best results.<br /> <b><a href="http://tft.vanity.dk/">Online Monitor Test</a> (Online)</b> This is a very thorough test not only meant to identify bad pixels, but also powerful enough to test the quality of your monitor. You can choose between three different modes to test your monitor. This tool either requires flash (online version) or it can be installed in the executable mode.<br /> <p><img src="fixpixel03.png" /> What you will need to just test for stuck pixels is the HTML window. Toggle full screen by hitting F11. What you will see is displayed below.<br /> <p><img src="fixpixel04.png" /> Move the mouse to the top of the test window and a menu will appear. There is an info window that you can turn off with a button in the top right of the menu. Then click on the homogenity test point and move through the three colors as well as black and white. Fingers crossed you won't discover anything out of the ordinary. In the unfortunate case that you do, you may find the following online tool helpful.<br /> <b><a href="http://www.jscreenfix.com/basic.php">JScreenFix</a> (Online)</b> Alternatively, and if you're not using Windows XP, you can use the online tool JScreenFix which launches a Java applet to fix stuck pixel.<br /> <p><img src="fixpixel05.png" /> The tool launches a small applet in a separate browser window and you can drag the window to the respective spot or run it in full screen.<br /> Hands On (Offline) Should none of these tools resolve your pixel issue, there is one last chance. You can combine any of the tools and the magic power of your own hands. There is a very good description of all available techniques on <a href="http://www.wikihow.com/Fix-a-Stuck-Pixel-on-an-LCD-Monitor">wikiHow</a>. Another great step by step guide can be found on <a href="http://www.instructables.com/id/Fix-a-stuck-pixel-on-an-LCD-monitor/">instructables</a>.<br /> But let's go through one technique real quick:<br /> <ol> <li>Turn off your monitor.</li> <li>Get yourself a damp cloth, so that you won't scratch the screen.</li> <li>Apply pressure to the area where the stuck pixel is. Try not to put pressure anywhere else, as this may trigger the creation of more stuck pixels.</li> <li>While applying pressure, turn on your computer and screen.</li> <li>Remove pressure and the stuck pixel should be gone.</li></ol> This works because in a stuck pixel liquid in a subpixel has not spread equally. In combination with the backlight of your screen, this liquid is used to allow different amounts of light to pass through, which creates the different colors.<br /> Should all of these approaches fail to fix your pixel warrior, at least you'll now know it's not simple to fix and the LCD may indeed need to be replaced. But please do let us know if these tips helped you to fix your pixels. In any case, good luck!

Change to resolution after picture taken


Sorry, can't be done. Those pixels weren't recorded, so there's no way to regenerate them.

Think of it this way. Suppose you look out the window and see a red car drive by. Look out the window an hour later and maybe a blue car drives by. Now, how many white cars drove by between those two cars? If you weren't looking (or had a surveillance camera), there's no way to tell. In your picture you've got a red pixel over here and a blue pixel over there. There's no way to tell what was in between.

There are some tricks that can be done to interpolate. If you have a bright red pixel and next to it a dark red pixel, then the pixel between them probably was a medium red. But maybe not: there could have been a blue object in between. Or the pixel in the middle might have been the same color as one of its neighbors. There's just no way to be certain.

I have a problem with the picture on my Infocus IN1501. It has small squares on it and I see every pixel. How do I remove this?


Generally the screen is full of pixels, and thats a good thing.
It's a problem when you see the pixels that should be off, and don't see them when they should be visible.

So I presume that your pixel problem may be the first type where they appear when they should be hidden.

Now it would be good to know if the bad pixels are all one colour, or if you have chromatic pixelation problems.

Monochrome pixel problems are better than chromatic pixel problems. But alas all pixel problems come back to the DMD or the colour wheel.

Either way your machine is basically compost material for the garbage shredder, unless you want to pay big money to replace the faulty bits.

Ask the local serviceman or servicewoman to give you a quote to look inside the unit and see where the pixels have gone astray.

Can i download pixel and vertex shader?


Pixel and vertex shaders are operations the video card may be capable of, sometimes the hardware is capable but the driver or directx are old and don't support this features. Check if your video card has pixel shading by looking at its specs in the manufacturer site, if it is update drivers if it is not you're out of luck. Though it is possible to do do shading by software, if this operation is not hardware accelerated makes the rendering very expensive time wise an thus slow.

Blue vertical line


The lines appearing on your LCD means it has a defect on the screen.

There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color

You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.

2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.

3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.


If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost

Pixel damage


Those small pixels are now damaged not much u can do with it. Some people say you can press on the screen the pixels affected and possiblilty get them to make contact and light back up ( I honestly highly doubt it) If u can live with and not very distracting keep watching it. But if you want to order a replacement, more than likely it will cost more than the TV did when u bought it. If its still under warranty get it replaced if possible.

Have a blue pixel that won't go away


One pixel is not repairable unless the plasma dislpay panel is replaced. That would be too expensive for that.
