Monitor is blinking and then went blank


Open it up and look at the capacitors. The round "tin can" looking components. If the tops appear bulged, then replacing them may help. Check out the YouTube video... and web site...

Emprex monitor lm 1905 - blacks out after a


If this has an internal power supply (no external brick) then you probably have failure of the capacitors inside. The problems exhibited by these failures are usually summed up as "works for a short while and quits" or "will not come on". Yours is probably similar to some Gateway monitors that I have repaired, The parts required for the repair should be under $10.00 and should take under an hour. Now you need to find a shop that can and will do the work unless you have soldering skills.

My emprex monitor has power but the image wont stay on. the screen somes on, shows an image for about 2 seconds then goes black.


This sounds like a backlight problem. I've had this with an acer laptop before and it needed a new backlight replacment under warranty.

Also check things like the connection cable, try it with a different pc, try a different (lower) screen resolution in case it's not compatible.

Monitor light: green yellow green yellow etc.


Cycling of the power LED (about once per second) is typical of a switchmode PSU shutting down and trying to restart. Often this is accompanied by a tick each time, from the main switcher transformer.

Assuming you can open the monitor up (with the power OFF of course) check all the capacitors in the PSU for signs of leakage or bulging. Ideally you would check them with an ESR meter, but they are usually visibly failed when the monitor acts like this.

Replace any defective caps found and try it again while you have the case off, keeping your fingers well out of the way.

Reverse KVM problems


If you are sure the left monitor?s power is not the source of the problem it does sound like a shielding or excessive signal loss in a device/cable. If it?s always the left monitor I would try unplugging the video cable that goes from the left monitor and plug it into the right monitor; do the same with the other monitor. If the problem moves to the right monitor then that eliminates the monitors and we move on. If the problem goes away then probably one monitor had more signal degradation than the other. If the problem stays then the monitor is the source of the problem. If the problem followed the cable then I would exchange the cables that run from the switch to the monitors; if nothing changes exchange the cables that run from the switch to the PCs. If exchanging any of these cables results in the problem moving then you have a damaged cable or a bad connection. If the problem is still on the left monitor unplug the cables from the left PC that run from it to the switch and plug them into the right PC; do the same to the right PC. If the problem moves then you might have a damaged switch OR perhaps the video card output on one of the PCs is weaker than the other. All cables and devices weaken the video signal to some degree but the amounts can differ wildly. Over the years I?ve had this problem caused by cables, switchboxes, video cards, radio transmitters, bent connector pins, poor connections, excessive cable lengths, monitors and accumulative signal loss from several devices. The last is the hardest to diagnose. Good luck and let us know what happens.
