Question about Samsung SyncMaster 193P 19" LCD Monitor

1 Answer

Black Out After 2 years of usage, 4 days ago, my monitor went down. Description: If the monitor is connected to the computer, the whole screen appears with vertical stripes, varying from approximate 1/4" to 3" and moving randomly along the monitor. The color of the stripes changes all the time depends on the program window open on the computer(Tested with another monitor). If the monitor is not connected to the computer, a vertical ~3" white stripe appear in the middle of the screen. After approximate 30 sec. the white stripe changes in 3 other small stripes(red, green, blue) at ~1/4" each, remaining on the same vertical position, and then static. In my opinion I need another monitor, or?? Thank You Detrix

    Definitely I will try to clean the circuits ASAP and see the result. If not, I will try another supplier power . I will get back after these tests.

  • Detrix Oct 12, 2007

    So, I opened the back panel. There are 3 Circuit Boards with 3 different sizes.
     I need to know which one is "LCD controller, the GUI interface circuit or the circuit
    supplying power" in order to communicate the electronics language.
    Now in my description:
    The big board has 2 inputs from the monitor leg support.
    From this board splits another 2 outputs. One goes to the small board having 30 linear pins.
     The other output goes to the medium board having 12 linear pins. From the medium board
    splits another 2 inputs and 2 outputs for the LCD screen. After this description I've seen something
    weird on the big board. After I took it out and cleaning the dust, and rotating the board in my hand, a small "clink" noise was
    there somewhere .I started gently to shake the board and after few guessing parts, I located the noise.
    It's coming  from inside of a (square  1/2 " resistor??) I believe. I can provide pictures
    to show the exact location.  The noise is like a small bearing ball into a bottle if rotated.
    My experience with electronics is not the best, I'm with mechanical stuff but as
    long as I remember touching other circuits, none of them were doing like this.
    So, I'm guessing this might by the problem so far, something burned inside that resistor, or whatever it is. My email at mechassembly@rogers.com
    See picture bellow.
    Thank you

    Hi Cerfer 39

    First of all, I want to thank you for your support and your time offered.
    Second of all, in previous discusion, I forgot to mention: After I cleaned all sockets I tried the monitor with everything open as is now, but still the same problem.
    I checked all components only visually, because I don't understand the measuring procedure
    with ohms??. Is it a measuring device?

    (Yellow) are the fuses, the (red) are the same but smaller. (Blue) are the ones at 1/4", but
    no holes. I checked again the noise, and I think it comes from the nut attached to
    the board(see Orange). Maybe a lost extra tin after factory soldering from underneath. So
    I don't think It's coming from the Eprom, as previously.
    I know the parts number, I searched on "http://www.partstore.com" but I will confirm with
    you again:

    1. ASSY CHASSIS-E25;DE1,  Samsung Part Number: BN9100836U
    2. INVERTER;RL17,SIC842,  Samsung Part Number: BN4400103B
    3. I did not remove the 3rd part yet. Should I ?
    See more pictures.




    I think I will do this:
    I will order both parts 1,2 and see which one is god or bad. And I will return back the one that I don't need.

    P.S. Latter I realized that the estimating procedure has to be done at the end.
    I'm new at this forum. I'm sorry, but we will fix it some how.
    I can send you better pictures. I need an email
    Thank you

Hi Detrix, Check with www.lcdrepair.net if you want a repair. Something is wrong with your LCD controller and or GUI interface circuit or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. These circuits take the Signal from the computer and controls the 2.5 million pixels on the LCD screen. Dsut can cause major problems with handling all that data. Give it a shot, what do you have to loose, its not dangerous if the monitor is unplugged.

    Hi Detix,



     



    Way to go man, on opening your monitor.  I want you to write down all the information that identifies each board.  We may need to use this information later, to order another circuit board.  That is not normal to have a clink noise. I never heard a chip clink before. That is not a resistor, it is an Eprom or processor.  The sticker indicates that a program is loaded on this chip.  They rarely ever go bad.  Now that you have the boards out and cleaned, inpsect them closely for burn holes in the square black chips that are bigger than 1/4" by 1/4" inch.   If you have a meter, and know how to check ohms, you can find the small black  surface mounted fuses with soldered ends. They are about 1/16" wide, 1/16" tall, and up to 1/8" long.  May have a number like 50 imprinted on top.   When measuring ohms and placing your meter leads on the solder ends, you should read less than 1 ohm across these.  If it does not read one way and you switch leads and it does read, your checking a Diode, and that is not going to help our situation. The easy way out, is to put it back together, and see if your cleaning did the trick. If not we need to investigate which board is the likely candidate to replace and put a call into www.lcdrepair.net.   It is awesome you have got htis far.  Way to go man.

    Wow, I am impressed with your effort Detrix.  My Email is Cerfer39@charter.net.  When I refer to Ohm's, I am talking about the resistance and the fuses ability to conduct current like water through a hose pipe. You will need to determine the resistance of fuses with a volt ohm meter, becuse these are not Glass Fuses like in an Automobile. In glass fuses you can see the filament that runs from one electrode to the other. The little surface mounted fuses do the same thing as glass fuses, but they are encased and you cannot see the filament.



    Alright I see that we need to stop working on Component level( Fuses and Chips), and go with PC board level.  This is a easier way, and faster than component level, but more expensive.   We will be more apt to succeed as well. I believe the one board that I posted is the one you should replace.  Since you can see lines, the backlight is working. Your getting a bad screen, and that is in the interface the reads the Signal from the computer.   if your going to get boards, and determine good and bad, get the ones that are between the Comuter connection and the gazillion trace ribbon that goes to the LCD screen.  The backlight part will only have two or three wires per light. I believe it is working.



    I will be around to help just make a post and I  get an amil every time. I am impressed with your effort and willing to stick with you on this adventure.

    Your doing the right thing by keep the LCD glass in the styrofoam .  That LCD glass is etched with Grooves, like a corn field.  It is easy to crack because it had thousands of score marks.   Alway treat the LCD screen with kid gloves. by the way I did not pay attetion to my typing.  Basically when you post a message, I get an email, not an amil.

    I have tried to find your parts at a better price and I believe the Partstore is the best choice, you done well in finding them.  SInce you do not have a black screen and getting some lines on your screen, that kind of rules out the Inverter BN4100103.  This leaves us with the LCD controller BN91-00836U, the connectors on the LCD , and the cables running from the controller to the LCD connectors.

Vertical black bars screen


Try connecting an external monitor to the 15 VGA (video) plug on the laptop and see if it displays properly on the monitor. You may have to direct the video from the laptop to the monitor by holding down the blue <FN> (key next to the space bar) and then press down the <F8> key.
If the display on the external monitor is correct, then you either have a problem with the laptop's LED display screen or cable that connects the LED to system board. Here is a link for the service manual:

I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.

Is the screen both BLACK and BLANK? or is screen just black and you can SEE win-desktop if you shine a bright flashlight 1 inch from screen at differnt angles? Can you use your Samsung warranty? Will monitor do same when connected to different KNOWN GOOD prebooted to desktop PC? Are you refering to the "power ON" indicator light on front BEZEL as the FLASHING thing?

2-3-4- years old benq FP19G = returned to office after lunch - burned out electronic smell in air - whole section of office electrically dead' - did reset = computer fired up ok - but screen blank...


Benqs have had some quality control issues but from your description the inverter board went on you. It needs to be replaced or repaired. Expect to spend about $100 for the repair so you may want to consider just replacing the monitor.

They can be fixed. The monitor I am using right now was one of those dead ones. It took a few hours to find as the rest checked out and it turned out to be a bad ground. Unfortunately when you smell burnt electronics you are not going to get off that easy.

Hp w2007 blank screen


we have here , like 1000s of black screens posted here now.
all the same all with CCFL lamps. that die. same solution.
older monitors have a power saver mode inside it,
push the front button called menu, then see OSD menu
then find and turn off power saver.
if the OSD fails to show up; the CCFL are dead.
this monitor was made in 2007, and 2010 is the starting year
for ending the usage of CCFL (starting on large screens working to small)

im reading your manual for you now, free.
page 4 tells you it has CCFT (T mean Tube, L means lamp)
same same.
https://www.manualslib.com/manual/1110533/Hp-W2007.html?page=4#manual

now lets look at the page on saver. power

page 7, (its on by default ) oops !
https://www.manualslib.com/manual/1110533/Hp-W2007.html?page=7#manual


turn saver OFF
see next page 8 and turn DDC ON.
see sleep timer and turn that all off.
if you push factory reset, it the problem begins again.
bad. for you.

https://www.manualslib.com/manual/1110533/Hp-https://www.manualslib.com/manual/1110533/Hp-W2007.html?page=8#manual

you can in fact download the whole manual.
for free. here. the site on the internet in this regard.

all old HP monitors are made for old PC 2000 year.
your PC is not 17 years old i bet.
so all this old saver stuff is now WRONG.
(all this is old school Energy Star , malarkey, )

Monitor goes blank less than a second after turning on.


I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.
