Question about Samsung SyncMaster 175V 17" LCD Monitor

2 Answers

Dim Monitor I have a Samsung SyncMaster 175V monitor. The LCD is dark, I can see my extended desktop, but barely.  Changing the contrast and brightness does nothing.The problem is not with the cord because, I have tried the cable with other monitors, and it works just fine.  When I unplug the video cable from the monitor, a "signal loss" message appears and moves around the screen, but it is not dim at all. I have absolutely no clue what's wrong, my only thought is that maybe the bulb is out.  I hope you guys can tell me what's wrong.

Re: Dim Monitor

I had the same problem, took it all apart and pushed on the socketed chip, it made a click noise and it works now. I also pushed on everything including the variable resistors. First time it's worked since it quit working!!

Re: Dim Monitor

The problem that appears is located in PSU or inverter or CCFL(backlight lamps). If the problem is caused by CCFL O do not suggest you to change them by yourself but you can inspect if the electrolytic capacitors on PSU board at 12V line (or inverter board) are OK. If capacitors are with blown top you can easily replace them.
Good luck.

My samsung lcd monitor have a dim light.. i cant see most of pictures or any thing that has a dark part on it... like pictures, videos

It is possible that the monitor settings have changed. There should be a menu or settings button on the monitor. Try to increase brightness and decrease contrast.
Unfortunately, it is much more likely that your monitor is failing and needs to be serviced or replaced. Given the price of monitors replacement is probably the least expensive solution.

I hope this helps. Good luck!

Dim display problem

Hi there,

Have you tried adjusting the LCD's bright and contrast using the buttons on the monitor. Instructions can be found on page 12 of this manual:

If the lcd monitor is dim even upon booting up, then the backlights of the lcd itself is starting to fail and it needs to be replaced.

Please let me know if you need further assistance. Thank you for using FixYa. Merry Christmas!

I rebooted my PC and now screen is darker and my colors are off

Check the contrast (darkness/lightness) on your Samsung LCD. There's a menu button on the monitor, press that and select contrast setting from the Menu.

SyncMaster 191t Screen is to dark. Brightness is set to 100%.

make sure you have the latest video driver.

Some video drivers you can configure/enhance your desktop settings.. ie. brightness, gamma, contrast..

If you're using windows, right click on your desktop, click Properties, choose the tab Settings, then click on the Advanced button. Choose your video card tab, and continue accordingly.

Dark scree

I too have the same problem with the same monitor.. tv looks great OSD looks great.. pc is dim.. This has nothing to do with the inverter board or the backlight.. I believe that there is an issue with the components that render the Computer video.

Samsung syncmaster 175v

This is most probably cause by one or more Faulty Electrolytic Capacitors, I find these are the MOST commonest form of "Fault" in these LCD's TFT's units. I ususally simply replace "On Spec" all High Value Electros, in fact ALL Electro's are suspect and often I just "Shotgun" and replace 'em all. Usually fixes all problems. Always use High Temperature Caps.

I had a similar problem with this monitor, mine was dim all the time to the point you cant use it, but the MENU icon was bright as new... also if cable was unplugged the box would float around as normal.... anyway I fixed it by taking it all apart and pushing in the socketed chip.. it clicked like it moved, I also pushed on the variable resistors on the power supply... now it works!!! First time since it quite working long time ago
