Samsung monitor 204b screen image is split in to two parts; the upper part OK but lower part is gibberish, ghosty?

The monitor shows split image, upper part looks OK, but the lower part is gibberish, streaking, funny meaningless images. But screen is stable. No power supply problem. It is bright.

Interference. Separate the wiring so it doesn't touch. Touching wires create cross-talk of signals and keeps from running normal.

SOURCE: Samsung 931B Monitor Screen will not stay

jane657, Hi there. Will you stop pushing the On/Off button on your lcd/fpd. It's Broke. Period. End. Finito!!! You will not fix it. However there is one test that you should do to determine hoe bad the problem is. You will need to reconnect the 931B to a known good pc that has been fully booted and has the WIN-DESKTOP or IE fixya web page showing. quickly connect the931B to the wall outlet and the PC. Turn on the monitor!!! Yes, I know it will only come on for a second..After the screen goes to BLACK, Shine a bright flashlight onto the screen at different angles, 1-2 inches from the screen. Let me know if you see something even though the screen is black. Anyway here are your options as a consumer/user. 1. Check if unit is under warranty. 2. Check withh Samsung to see if they have a SWAPOUT program. You send them your monitor+$40-$90 and they return a refurbished same model to you with a 30 day warranty. 3. Trade in for new monitor. 4. Check with local TV/Monitor repair guy who knows all there is to know about cold-cathode-fluorescent-tubes, their power-source(inverter type) and lcd monitor power supplys (SMPS) 5. Repair on your own. Not recommended for amatures with no solid state troubleshooting skills and no instrumentation for support. Bye for now. I'm louie12fix on fixya or lmistyrel@ aim.com

SOURCE: Samsung monitor has "streaks"

LaurieEm posted a solution which seems to work for me (in addition to some other stuff, read my problem description) for this here http://www.fixya.com/users/laurieem

Try re-plugging your LCD monitor's VGA connection. It may be a case of corrosion on the pins or bad puggin of the cable. The problem is also reduced by using compressed air to blow out the cicuitry in the back of the monitor to remove dust. Both of these seem to work, and if you can't solve the problem totally with one, try the other one as well.

SOURCE: Screen flashes - samsung 215tw LCD monitor

walkstex, I will answer the last ? first. All LCD monitors WILL NEED to have their "cold-cathode-fluorescent-tubes" replaced!!! As long as your display had a Bright, Crisp image displayed on it before this "FLASHING" symptom occured, then you don't need new CCF tubes. Your problem seems to be occuring in the electronic ballast circuit called an INVERTER. It Takes 12-15v DC and turns it into 800-1200v ac to light up the CCF tubes. This is the same technology used in the new style curlieQ screw-in light bulbs called CFL's. Only difference is they use what is known as a CONVERTER circuit----AC to AC!!!! And the tubes hung horizontally on the rear of your LCD panel are thin and straight. So, to answer your first ? Yes, it is an issue of getting the CCF tubes to light up. (backlighting) Now, I should also mention that there could possibly be a problem with the main power supply in the monitor. It is called a "switch-mode-power-supply" (smps) that supplies DC for the digital signal processing board (typ +5v) and 12-15v for the inverter. Well, This typical type of symptom could be as simple as a thermally fractured solder joint on the power supply board or some bad Filter capacitors could also need replacing. I suggest that you search web to find out more about the things I have mentioned in the above text. Do search for things like "swollen capacitors", "Bulging Capacitors" and checkout www.badcaps.net for some pictures of typical failures. Get back to me if you want to carry this any further on your own. Bye for now. I'm louie12fix on fixya or lmistyrel @aol.com

SOURCE: I have a Samsung SyncMaster 931c monitor (2.5 yrs

jcacolice, Most likely your 931c will need work done on it. When strange things start to occur with any LCD CCFL backlit display I would suspect the "switch-mode-power-supply" first thing!!! If unit is out of warranty you or someone will need to inspect and troubleshoot it. A good place to start will be to see some DIY videos on YOUTUBE. Try search of "lcd monitor disassembly" and "lcd monitor repair" and learn all you can about the TOP CAUSES of monitor failure. Then visit (FYI) www.ccl-la.com/badcaps.htm and www.badcaps.net for more info. Explore ALL your options before you do anything. Then get back to us here at fixya if you still need some asssistance. Read some of my other responses in my fixya profile and other those of other tech's on fixya.
Hope to see you back on fixya with a plan of action!! 12fixlouie

ONLY BLINKING POWER BUTTON ON THE DMONITOR. NOTHING ELSE IS THERE.


Hello,

This is a common problem with the Samsung 204B units that have been in service for a few years. Parts called capacitors in the power supply start failing and causing the board to not start correctly. The blinking power button is just the power supply restarting over and over. The monitor is easily repairable, you just need to replace the 5 capacitors that have failed. Here is a link to a page that shows how to open the monitor, get to the power supply board and what to replace.

How long have you had the monitor. It sounds like a defective backlight. Usually when the circuit driver for the backlight starts to go bad, the monitor will blink. If this is the case, eventually the monitor will not turn on at all.

Replace the screen with a known working one. If it shows display then it is the screen which is broken, if not, then it could be the port on which it is connected.

Only getting 1/2 screen upper half black


Try connecting the monitor to a different computer.
If you get the same symptoms, take the monitor to a qualified technician -- they probably will charge your $25, and then tell you that the electronics inside the LCD are damaged, and that you'll need to replace the monitor. Instead, exercise the "warranty" on the monitor, to get it replaced, or "invest" the $25 "inspection-fee" as part-payment of a new monitor.

I have a 204b moniter that the lower half of the screen faded to black then shows two half screens that are filled with so many vert lines that you can't see whats on the screen.


the screen is toast. if its black and not showing whats suppose to be on the other half.if you tried restarting the computer and unplugging the monitor and it is still happening then there is nothing to do. monitors are not built to last long, the cheap ones. it is good to get one with a good warranty because the pixels go out.
