Bruise to Samsung LCD screen

I recently moved my 52'' 1080P LCD screen into a new apartment 
Anyways, moving went fine (or so I thought) until I tuned my television on an saw multiple verticle lines on the right side of the screen. The lines are colored (red, blue and white). It also looks as though there is also a small section that was compressed or bruised. 
The rest of the screen is static except for one central area that is a darker gray than the rest. I assume this is a bad indication. 
Is this television beyond repair? I'm rather devastated over this. 
Thanks for any and all help.

    No there is no distinct spider webbing. The are that looks as though it may of received the pressure is gray and oval-shaped.

    My roommate, upon first looking at the screen, thought that something had hit it (which is not the case) if that gives you any indication of what it looks like.

SOURCE: Blue Convergence

Convergence problems are generally simple repairs, presuming you know how to solder and have a bit of brains about you. Eventually every projection set will have this problem - STKs are usually at fault (STK392-010/020/040, STK392-110/120/150/180, etc) and are easily aquired and replaced. Sometimes a fusible resistor is taken out in power supply circuit, sometimes a resistor will burn. Generally easy fix. Repalce STK and any fusible/blown resistor - you will need a multimeter, decent soldering equipment (NOT a 40watt iron or gun from Radio Shack, unless you're brave) and the replacement parts. But as everyone says - servicing TVs can be hazardous. Call a servicer if you're concerned, but in-shop repair should cost less than $250 - it would never exceed that at our location.

SOURCE: Zenith 60'' LCD TV a blue screen is not sky blue it looks dark blue to black

Go to zenith.com, look under the service icon at the top and then you should see a listing for "Class Action Lawsuit/Settlement". If you follow that link, they'll have specifics listed for this suit that was brought against them (including tv model #s included in the suit). There was an agreement reached to fix/replace affected t.v.s, court date was in Feb. I believe, and just waiting now until they post information on how to proceed.

Good luck and hope that helps.

SOURCE: Blue section (corner) and blue dots

This set has no internal manual adjustments for color. The Tracking or B&W balance is accessed via the service menu. I don't suggest you attempt to adjust without instrumentation. the trouble with your set is not an adjustment. Most likely the Optics are at fault. This model has had issues with filters in the optics being destroyed over time by the lamp. The blue haze will get worse and continue to grow over the whole picture. The only option is to remove the Optics (light engine) and sent it out to be rebuilt.

SOURCE: the Screen looks 3D & Colors don't line up on my big screen????

If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

Is it an LCD tv or CRT ?
If CRT try moving the TV to a different location as the magnetic field from another device or even the earth can effect it.
The power switch (full power on) would normally demagnetise the screen.
If its an LCD has any object hit the screen, it could be a child's toy or knocking the screen can bruise the panel.

Acer Travelmate LCD screen went dark


The same thing happened on my HP. I ended up buying a LCD screen off ebay. That corrected the problem. New screens cost $150+. You can get one off ebay for half the price.

Screen Problems with my Laptop


hi dear

1. That can be connection related problem. I check connection between the video cable and the LCD screen, try reconnecting the video cable. It’s necessary to take apart the display panel, unplug the video cable from the connector on the back side of the LCD screen and then plug it back in. In some cases reseating this connection helps. 2. If reconnecting the video cable doesn’t help, here’s what I do in this case. While the display panel is still disassembled, I turn on the laptop and wait until image appears on the screen. Then I move the video cable a little bit without touching the LCD screen. If moving/touching the video cable affects image on the screen, it’s possible that there is a problem with the cable. Apparently there’s a short somewhere inside the cable. In this case, replacing the video cable may fix the problem.
3. If reconnection the cable doesn’t help and moving/touching the cable doesn’t change image at all and the only way to get better picture is moving/touching the LCD screen itself, apparently there is a problem with the LCD and it has to be replaced.


oke

Screen goes blank when I move the mouse


Did it work properly using a VGA (analog) cable? If so, check your DVI (digital) cable against the pictures at the bottom of http://www.datapro.net/techinfo/dvi_info.html.
You probably have one of the two at the left. Each has a different bandwidth, translating to a maximum resolution. The native resolution for your monitor might be marginal if you have a single-link DVI-D cable.
My 204B seems very picky about signal-level. It blinks when connected by DVI, even though it should be fine with a single-link cable, and complains about the settings even though the settings are optimal. Maybe yours is similar. I have ordered a dual-link cable and will try that myself.

LCD screen has fine pink lines and is changing colors


The LCD might have developed a fault. First try and ensure that the flexible film kind of connector is firmly in place and not damaged. As a final resort the LCD is to be replaced. For spares requirement you can write to me. If it is under warranty pl.try the nearest Sony service center. Sivaram videolabs@gmail.com
