20 Most Recent Dell UltraSharp 1900FP 19" Flat Panel LCD Monitor Questions & Answers

Eve, To get the lock to go off the screen you can press and hold the monitor Menu button for about 10-15 seconds. Thank You, Dell-Jesse L Dell Social Media and Communites

Is there a save in the menu? Unplug monitor from power for 5 minutes.

Try to remove the power lead for a minute. That should help

try to remove power lead for a minute or two and put it back in. Should be better.

Sure. There are many CCTV cameras that can be connected by RCA cables.

Go to GOOGLE and type DRIVERS for your exact product and model of monitor, which will hopefully give you the correct drivers to download. Softonic would be one place to look. CNET would be another.

Open and look at the tops of the capacitors. I bet there are at least 2-3 "bulging" tops. Replace them and the problem WILL be solved;.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series. Please leave rating if it helps.

Hey,

the problem is either the powersupply, the inverter, lamps or the mainboard.

It could be as simple as few bad electrolyte capacitors on the powerboard or it might be as bad as a faulty mainboard, or the inverter for the backlights is not working anymore.

If you want to fix this yourself you really would need previous experience, replacing both the mainboard and powersupply yourself is going to cost around the price of a used monitor or a new monitor, you would need to know your way around these things to repair them.

to make sure the backlight lamps work you would have to test them on a laptop inverter or another working display.

if they are all OK and light up, then the issue is either the powerboard or mainboard, you would need to measure the voltages going to the mainboard and that they are up to specifications.

If the voltages are steady and look good (12, 5, 3 most likely) then the issue is either with the inverter circuitry on the powersupply its unable to power up the backlight inverters or its not geting proper feedback signal from the backlights telling the board that theres something wrong and it won't stay powered on (blinks on and off)

in that case you would probably have to replace the powerboard.

But now back to the blinking amber if you disconnect the vga cable or dvi cable does that change to change signal cable?

if it keeps blinking then the problem is what I've already posted.

if it stops blinking and you get no signal picture on the screen and it stays on the screen, that tells us that the powersupply, inverter, backlights are OK.

the mainboard of the display might be malfunctioning, it looks like its unable to read the signal from the computer, try another pc if possible or another way of connecting it to a pc.

the mainboards components are too small for us to get into at home, the most likely issue is the MCU chip that would need to be replaced to a new one (or a working one from another same model display not sold separately) or then the bigger chip that processes the signal is faulty or has lost its programming.

For you as a home user you can only replace the mcu or the whole mainboard to solve that problem. it just gets way too complicated after that.


I hope that you credit me with the 2$ for my time and effort on this solution, surely I've atleast saved you some time, and definitely the above is worth more than 2 $.

i connected hp laptop to toshiba tv, no picture , but sound is there

CLick start/run then type in dxdiag. Go to the display tab and click test dirext3d. There should be an 3d cube that comes up and spins around. After the cube leave cancel everything else and close dxdiag, Your problem should be solved for a pretty long time. If it happens again just follow the steps again.

1. turn off your computer
2. turn off your monitor
3. Unhook the power and video cable from both
4. Reseat them both on both ends.
5. Turn on your monitor
6. Turn on your computer

If its still doesnt work after all 6 steps, your monitor is bad, sorry.

Bad video card? Substitute another to see.

From where I sit, understanding LCD's and all thier quirks I would buy it.

From where you are with your technical terms you can go 2 ways.. both good.

If you can get this cheap and have no expectation of getting it to work, it could be a valuable learning tool for you in future screens.
Secondly, you could open it up and find a few dead capacitors that have been messing with the power supply to the panel and causing the issue, correct it for a few dollars and get it running again.

Like I said, it's really a win win as long as you accept before you do it that it may just end up being something to help you later on.

you can push every lamp from 19inch monitor who have same jack for conector{i work that, i have dell1900fp}!!!sorry for eng.good luck
