SOURCE: Monitor dark only when display PC, normal TV

hi have you checked your PC output? check it with another screen (whichever) and see if the output signal is good if soo check the cable and connections to your LCD check your PC for software configuraitions: 1) TV output 2) good resoulotion 3) media borad is strong enough to handle this LCD if all is good then maybe the TV borad is sending a low voltage/current then the LCD can see good luck

Click the top button on the side of the monitor to open the monitor's settings. In the "Picture" Settings, scroll down to "MagicBright" and open those settings. Chances are you have it set to "Dynamic Contrast". Switch that up to any of the other settings and then it won't try to adjust the gamma based on what is on the screen.

Hope this helps, I struggled with the same problem for quite a while until I found this setting.

SOURCE: Backlight going bad?

Hello,

This is not the backlight its the power supply board. We have a repair guide posted on our web site at: http://www.ccl-la.com/blog/index.php/samsung-204b-lcd-monitor-repair/ The repair consists of replacing 5 capacitors on the power supply board. If you can solder then you can do this repair. If you don't want to do the repair we do offer a repair service, you can get this information here: http://www.ccl-la.com/blog/index.php/service-request-form/

I hope this helps, If so please rate our solution.

Testimonial: "I know this has been quite some time ago, lol. I did since replace the capacitors and still had an issue. There was another component that went bad (can't remember what) which was too expensive to replace given the price reductions on newer bigger monitors. Thanks for your help!"

I have samsung syncmaster 933 monitor. It keeps blinking on and off. We have rebooted, unplugged and replugged all connects from pc to monitor and still it keeps blinking on and off. Not able to...


It may have unstable DC voltages due to failing DC filter caps which is very common problem to all LCD monitors as shown in my albums.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Sounds like your resolution is not set correctly.

Try going to Start-->Control Panel-->Display and choose the Settings Tab

Under there change the resolution slider bar to 1280x1024

Should do the trick!
