Question about Dell UltraSharp 1800FP 18.1" LCD Flat Panel Monitor

1 Answer

My Dell 1800FP monitor is dead. There are no lights and no image on the screen when plugged in. I replaced the power module already and checked it with another known good power supply but no luck. What do I check next?

    I already replaced the entire power module (which includes this chip) and tested the new one in a working monitor. I need to know what the next most likely problem would be.



    Thanks

Check the switch mode power supply IC for shorts. This is very common problem for this model, you can get the repair kit for it on EBAY.

Video on 1800FP flashes on and off.


You need to check the output voltage of the power supply module to see if the 12vdc output is swtiching on and off, it can be power supply failure or it is sensing short circuits, it can also be the inverter board.

May lcd monitor dell not power


Hi,


If there is no power or "Led" indicator on the power button, try plugging the power cable to a different power point. If still won't turn-on, try changing the power cable. If still no power. It only means the LCD is already deffective.

Hope this helps.

My Dell 1800FP monitor went black


Confirm your cables did not work themselves loose. Try using a different power cable to confirm that it was not the cable. Finally try a lamp in the socket you are using for the monitor power cable, if you are not using a power bar but even then just to rule that out. If the only thing left is that your monitor is dead, you will need to recycle that one and purchase yourself another one. Sorry
