Question about Dell E173FP 17" LCD Monitor

1 Answer

MONITOR KEEPS GOING OFF.

THERE IS A LITTLE KNOB ON THE KEYBOARD TO THE RIGHT OF THE LOCK AND UNLOCK ICON ON THE MONITOR. The monitor keeps going off and pressing this knob brings it on however it is not working properly. The monitor stays on for a fraction of a second and goes off. If I keep pressing the button it eventually stays on for a short time. I had this trouble when I first got the machine and then it settled down and I had no more problems so I didnt report it but now it is doing it all the time. I can sometimes see the monitor for a few minutes like now and other times it goes dark although you can still type and see what you have typed when it lights up again. You can just about make out whats on the monitor in the dark so the actual computer is still on. What should I do. Can I stop this knob from going off?

Same as all else. I have a Dell 17" that keeps going off when first initiated. After about 12 to 18 times, turning off then on again, it seems to stay on but it takes longer and longer. Is this a problem with the monitor? or is it something with the computer? It has been suggested that it could be the back light....but I don't know how that works on an LCD flatscreen

Try your monitor with another computer. If it's still a problem. This is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After the monitor goes off, you check that you can see the image on the screen by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

My SAMTRON 56v monitor is having a problem. The Monitor's menu appears by itself. It was discussed in a previous description but not resolved. It shows the control lock window and will fluctuate between...


I'm not sure about the locked/unlocked bit, I assume that you use the menu button to cycle through the two.

I've had a similar problem on a IIyama 19" monitor. The menu kept flashing up randomly all the time. I discovered that it was due to the menu button being faulty, I removed it and it works perfectly again, still haven't gotten a new one for it yet.

it's under warranty then send it back to be fixed, although you'll probably have to pay for it to be sent back etc. If not then you have two options.

1. Pay a tv repairman or similar to fix it for you. Possibly the most expensive option.

2. You could remove/replace it yourself if you're handy with electronics, or know someone who is. The part itself is called a tactile switch and should cost around £1 if you live in the UK. Make sure you get the correct one as they come in different heights and orientations.

Should look something like this:

Tools
-------
1. Soldering iron - 40w+
2. Solder - not acid core
3. Phillips and flathead screwdrivers

Instructions
--------------
1. Unplug monitor and open case, you may need to carefully lever the case off with the flathead screwdriver.

2. Find the little board with the buttons on, and identify the menu button.

3. Very carefully heat up the contacts on one side with the soldering iron, you'll probably have to do the two contacts at the same time, and rock the switch the other way, then do the other side, keep doing this until the switch comes out.

4. Either test without switch first or just replace with new switch. Make sure it's securely seated, correctly, and soldered in. Make sure the solder is neat, tidy and doesn't contact anything else.

5. Replace casing and test. If it doesn't work then you'll have been a bit messy with the solder, tidy it up and try it again.

My F22 monitor had been appear OSD locked and i don't know how to solve it. Some buddy please help me!!!


important notes
1. what is displayed on the monitor comes from the system unit
2. possible features that could be displayed on the monitor are screen savers or splash screens
3. attempting to log on a computer with a screen saver passcode could lock the system by displaying the word locked requiring unlocking

procedure of unlocking a passcode
1.Once the system locks, would require to reset the password.
2. another function could be displayed on next to the lock icon prompting unlock or reset
3. in the absence of a display of unlocking the password, continue to enter the wrong password and hiting the logon button in a space provided next to the unlock icon prompt
4. severall attempts would prompt for a reset functionality.
5. at which instance would display a password hint of what has been locked.
6. the password hint provided must be guessed correctly to allow a reset functionality.
7. once hint provided allows for reset would prompt the user to create a new password
8. create a password with a hint as a key to reseting any future locked screens.
9. the screen could be operated without a password for an alternative, only made possible during after unlocking the locked screen. instead of creating a new password and hint, choose to disable screen savers altogether.

Here you go!
From Dell website:
'OSD Lock': Controls user access to adjustments. When 'Yes' (+) is selected, no user adjustments are allowed. All buttons are locked except the menu button.
All buttons can be locked or unlocked when the 'Menu' button is pushed and held for over 15 seconds. See more here:

When the icon is in the unlock position, hold down the Menu key (the far left button in the lower righht hand corner) on your monitor. This should bring up the menu. From there, you can reset the factory settings.

Monitor displays "Controls Locked"


This is a "feature" they include to prevent accidental changes to the screen setup. You should be able to unlock the OSD by pushing the Menu button and the right arrow button together for about three seconds. The message "controls unlocked" should appear. Let us know if you have any other questions and please don't forget to rate the posting.
