    Exactly the same problem with my 204t. Tried it on numerous computers, different video cables. I've opened it up, found nothing obviously loose on pcb, put it back together and it might work for a couple of days and then back to the 1/2 second picture. Errr!

I had the same problem and fixed it replacing 2 820uF capacitors. Check-out the website recommended by Buddy. I purchase the parts at my local electronics parts supplier for $3.

Sounds like it might be getting too hot and/or going bad. Not sure how to diagnose this without seeing it myself. That is the best that I can do. Your video card could be going bad. Try another video card on that monitor. This will be the only way to decide if it is the card or monitor. Try it on another machine and see what it does.

Screens shows but then gos black


Confirm that all the input cables at the back are securely plugged at the rear of the screen and PC/output source and that the image source is switched on and displaying an image. This can be done by switching your PC on and waiting five mins. Then check that the power for the screen is on. If this does not work, then let me know

Tmy monitor shows the images only for 20 seconds, then it turns black.


Hi hope your monitor issue has resolved. I would suspect the problem is a hardware issue then a software setting. Since the monitor is over three and half years old, if your monitor is a LCD with CCFL back light and had been used almost every day, there may be 3 possible hardware issues. First is the internal power supply, that can go wrong due to heating problem within the monitor, this problem usually cause the monitor to display poor quality picture and may show interference lines on screen prior failure. Secondly, it may be the inverter that drives the back light, which may fail due to the safety circuit kicks in, because it involves with high voltages. Thirdly it may be the backlight itself, which is like most compact CCFL energy saving lamps that flickers or turn itself off when it reaches the end of its service life. This problem usually caused the monitor to show redness or yellowness images prior failure.

All of these can be resolved by qualified electronic repairers, all the best.

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

Monitor blacking out intermittently


Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.

Monitor only stays on for 3 seconds


There is probably a bad capacitor within the monitor that will not allow the picture to "hold" in the on configuration. This will need to be replaced. You can send it back to Phillips, or 17" monitors are pretty cheap these days. I would suggest a Samsung or BenQ. They both carry 3yr warranties.
