460DXn screens with check cooling system message
« on: September 11, 2012, 11:58:23 AM »
Hello all

a few of our screens have begun showing an error message floating on the screen "Check cooling system".

We have removed them from the wall and as they are out of warranty had a look inside.

After blowing out all the dust the message remains.

We have replaced the three 60cm fans but the message still comes up after 5 mins or so.

Temperature in the server diagnostic is around 65 degrees max.

Anyone any ideas please?

Thanks :-)

We've had two of our three 460s serviced because of that problem. They replaced the power board for the overheating and a small board for some discoloration problem in both lcds. The tech said it was mainly the power board for the error message. We luckily had them still under warranty. We are now experiencing the error on our third lcd, which unfortunately has passed the warranty period. You also might be able to make the error disappear by pressing the menu button on the monitor itself, but it'll come back if monitors are turned and off.
