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

1 Answer

Dell 1800FP, no signal found (analog). Green LED on, get message

When I power on the monitor, it does not receive the video signal, I get the box that says no signal. This tells me that the backlight works. I checked the power supply and found all voltages present. (from top down, GND, GND, 5V, 5V, GND, GND, 12V, 12V). What could be causing the screen to remain black?

    Double checked power supply, replaced with a PC supply and still have same symptoms. I do not think it is the power supply, it has to do with the video card? The backlight works, so it isn't that section. Any ideas?

Led flashing no picture


disconnect the signal cable from the computer. if it shows color bars, it means your monitor is ok and your video card is faulty. if it still does the same thing. you need to reseat the video card if its not integrated.

hope this helps.

Self-Test Feature Check (STFC) Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
  1. Turn off both your computer and the monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
  3. Turn on the monitor. The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
  4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Thanks

Dell ultrasharp blinks on and off


It could be a setting problem, power saver setting, or a mode that the monitor does not really support - things like refresh rate - or actual hardware.

Easiest way is to borrow another like monitor, and say another video cord and see if the problem remains, or if a newer monitor says 'out of range' or similar.

Then, if you have a fancy video card,remove it and use something primitive. Not reading instructions is a big cause.

If its not a setting issue, and as the inverter board is ok; if the above description is correct, reseat the inner board connecting cables.(wood fires and seaside locations) If not that, a lucky guess might be the electros on the logic board.

Analog Dead/DVI OK


Sounds like the video controller board inside the monitor has blown a transistor. They are only about 3mm wide so not easy to spot even if you look closely.

It's a fairly rare fault, though not unknown to happen without reason.

Dell UltraSharp 1800FP - display leak - blue craziness


That one is going to take component level troubleshooting. It could be the power suply, but I might first suspect the video board.
