There may be a virtually invisible polarity symbol on the case next to the connector.

SOURCE: Cornea Monitor Troubleshooting CT1700

it could be something as simple as your power settings in control panel> power options, then the first window called power schemes pops up and all monitor, harddisk and system standby should be set at never. Also check on you monitor menu for any power saving options and turn them off. If the monitors still turn off then there has to be a deeper fault with the monitors and not with the power options.

Apparently the monitor's power consumption is near or slightly exceeds the specified value.
My suggestion would be to purchase an adapter with higher rated output current - if for example your original adapter was rated 12V 4.5A, go for a 12V 6A rated adapter. A 30% safety overhead will hopefully contribute to higher reliability.

When I turn on my Cornea MP503 monitor on it has a message in a blue box saying Power Saving Mode and then goes blank and light flashes orange-green over and over.


Check the VGA/ DVI cable connection from your Monitor to PC, this also could be caused by VGA card on you PC that doesn't work properly, unfirmed connected to its slot etc, check also for unfirmed connected memory card/ RAM.

check out if the electric alimentator are fine, the cords and the conections, check the properties too, maybe a stand by settings are on and make you this "power saving mode" if none of the anteriors was... then could be that the monitor have done the limit of hours, if the monitor was new try on warranty, if the monitor doesnt have warranty you can explain more about this trouble so i can help you more given you specific intructions

Screen is black when turned on


You may have failure in the backlight inverter circuits (shorted transistors, failed inverter transformers), power supply (bad caps), bad lamp assemblies. If you are going to DIY repair, please look through my albums so you will know what to look for inside.

Need driver for Cornea MP704


Hi
I have the same monitor on one of my test benches. For a long time I tried to find drivers for this because I thought it would make a difference. Finally a year or so ago I found a drivers company which said they had it. For $20 I could download it and many others. I did so and didn't really see much improvement when I installed it. I finally got to thinking that maybe I should look closer at this code I purchased. Well as I suspected this code was actually the Microsoft generic LCD monitor code which had been relabeled. I turned it over to Microsoft. But to answer your question I have never found drivers that are specific for any Cornea monitor. Sorry

External Monitor


No. This is almost certainly a setting issue. Go in to the control panels and change the way the monitor is used. I.E. extension desktop, mirror, etc. Then check the settings for the second monitor and make sure it is not set to some huge size or resolution. This is a function of the MacBook and OSX. I had a similar issue when connecting it to a 71" DLP.
