Hi either the power is plugged to the display wrong, or then the power adapter can no longer provide the required voltage, the powersupply would either need repairs or to be replaced. The light dimming is the key sign of failure here. the powersupply is most likely unable to provide the required power the light dims out when its under too much load that it can't handle anymore. either take the powersupply to a electronics repairer or replace the powersupply.

    Only if the voltage rating and the polarity of the adapter are the same.

    if the voltage is higher than the original power supply, you will ruin the display. Very small voltage differences possibly 0.5 volt difference might not cause any problems.

    next the more important thing, you need to make sure that the polarity of the plug that goes into the display is the same on both power adapters.





    You will find this kind of small set of symbols in the label of the power adapter, both adapters must have the same polarity or you risk ruining the display in a way that will require further repairs or replacements inside the lcd monitor.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, 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 PRINCETON monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Need cable and power supply


Power Adapter Input AC 100-240V, 50-60Hz, Output DC 12V/4.0A

This may help. Just make sure you have the right dc output mentioned on the back of your monitor (12v4a or 12v5a) if any lower your monitor will shut off after displaying for few seconds then electrical smell will come out from your ac/dc adapter. When it overheats it shuts off.
