    I used my DELL monitor in place of the SAMSUG 931 and the DELL worked just fine. I am concerned about the flashing SAMSUNG power botton. The SAMSUNG gets power and I can hear the CPU recognizing the SAMSUNG monitor (you can hear the "da-dunk" recognition sound on the speakers), but no picture.

Try it on another PC, if it still does not work and you want to DIY repair, please read below and look at pictures.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 SAMSUNG 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.

    Well, you will need to open up the monitor, the 5vdc for the logic is working but the 12~18vdc for the inverter circutis may not be working, or the inverter circuits, lamps assemblies amy have failed.

My computer is not showing when my camera is plugged in


Make sure the camera is turned on, plug the USB cable into your PC first, then into the camera, wait for a beep from your PC to show it has recognized the hookup, then go to "My Computer" and look for the Fuji icon. Don't unplug the camera anytime the lights are flashing on it.

No sound from monitor speakers. Worked fine for 5 years. Can hear sounds when using headphones plugged into CPU. Hope you can help even if only to tell me I need a new monitor. Sincerely Dizzyme.


Hi...there,
First of all, check if your audio cable are still plugged into the monitor and pc output (light green) audio jack. If not just plugged it back in... Still still got no sound... Then turned off the monitor and pc. Unplugged all the cables from the monitor and pc, wait for 10 second till all the surged built up are cleared out. Then you can plugged all the cables back Monitor should have 3 cables, a audio cable, a VGA or DVI cables, and a power cord... OK! now you got all the cables plugged back in...
Turned on the monitor and PC....and a few seconds....you should hear window started. Still... had a problems....just get a external speakers. Have nice day!

DCLCD 19" flatscreen won't turn on correctly


Same problem here, but after using the plugging/unplugging method it eventually stopped all together. So, I took it to a local monitor repair shop (AM Stereo, Seattle). The problem is a power supply issue where the capasitors go bad. They fixed the monitor by replacing the capacitors for $70. In there experience, all monitors, regardless of brand, tend to use the same cheap capacitors which fail. He replaced them with better quality capacitors which may make this monitor better than it ever was. I'm back in business with a great monitor!
