Question about Samsung 172X (Silver) 17" LCD Monitor

Open Question

172x switches off during operation

Hello ptkent
comming back to the Samsung 172x problems, which all seamed to appear about 4 years after purchase (in 2008 for most users).
My LCD also switches off during operation after about one to two hours. The green status LED switches off and the screen switches off too.
When switching the screen off and then on again the status LED is on for 2 seconds and the goes off again without the screen showing anything.
If you remove power you can use the LCD again after about one hour.
I love my LCD and would be thankful for directions.

Thank you for your answer to tim-fuss@gmx.net

looks like you have a DRY SOLDER or COLD solder , if your handy with tools , you have to open monitor and check the PC BOARD, specially where some transformer is located look around that area for some burnt spot , re solder it , and try it again , should be working properly , hope this helps AJ

Simplest solution may be the screen resolution settings are set higher than the monitor's capabilities. Try lowering the screen resolution and refresh rate in the display properties or try booting to safe mode (press F8 when the Windows splash screen first appears) and see if the LCD will display the windows desktop. It that works, check your video drivers and the screen resolution and refresh rate settings.
If the monitor has the problem in safe mode and/or if lowering the screen resolution and refresh rate don't help then I suspect the a problem similar to one some Dell 17inch LCDs have. On the Dells It is usually caused by a defective voltage regulator transistor in the backlight inverter circuit. Troubleshooting that problem should only be attempted if you have experience at repairing electronic circuitry since it will involve testing individual components and soldering.

Do you have the video set to a range that this display cannot handle? Try rebooting into Safe Mode and set the resolution down to 800x600 or 1024x768 and see if it that will get you back. If so, then look up the specs of the display and set it no higher than it's max.

If it physicaly powers OFF, then you probably have a power issue.

Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors will blow a power supply. The problem is caused by parts called capacitors overheating in the confined space of the monitor. If you are good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work fine. The capacitors do need to be installed with the correct + and - connections, note the stripe on the old one and insert the new one the same way. Look in our monitor repair section for step by step repair guide for this model it should be the same power supply as the 930. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

I hope this helps, if so please rate my solution.

Hello,

This problem usually indicates a failure of the power supply board that runs the video control board. You can fix it but if your unit is only 1.5 years old then its still under warranty, 3 years parts and labor. Go to www.samsung.com and go to the service section to start a warranty claim. It takes about 2 weeks to go out and back to you.

I would follow the self-test below. If you see the same issue in the test screen then your monitor has lost it's sync and would need a board replaced.

If it dosn't appear during the test, then you might want to test it on another PC.

Self-Test Feature Check
1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on the monitor.
If the monitor is functioning properly, you will see a box in the illustration below.

This box appears during normal operation if the video cable becomes disconnected or damaged.
4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.

If your monitor screen remains blank after using the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Get rid of volume bar in middle of screen


I had this same problem a while ago. It was because the top "touch" button on the side was being triggered at a rapid rate. I took mine back to the retailer because it was within the Westinghouse 1 yr warranty. After getting a replacement display (same Westinghouse 22 in), I have had to take it apart because of a bad video processing board. In doing so I have seen that the side buttons are very easy to get to and fiddle with. If you are out of your warranty period, perhaps try taking off the case of the display and fiddling with the button board and connections

Samsung monitor 970p triple hinge.. hinge collapsed how to restore


From doing a good amount of internet research I have found that this problem is "fixable". Inside the top portion of the arm there is a spring. That spring was made to support the weight of the screen, but after readjusting the screen so many times, the spring loses its ability to hold the weight. If you take apart the top part of the arm (the top part, not the sides, pop it off with a flathead, be careful) you can fix it a number of ways. I used a zip tie. Go right through the middle. and tighten it until you get the screen where you like it (forever). thats just want i did. Do some googleing people!

it has nothing to do with your computer, if you put the monitor on a different computer it will do the same thing. the message comes directly from the monitor itself. you have to keep your screen resolution at 1280 x 1024

Brown horizontal lines sporadically appearing on monitor


I have exactly the same problem with the identical monitor, but I have not found any solution. It seems to be the monitor causing it because I can't see the lines, when I make a screen dump.
