Question about Dell E171FPb 17" TFT LCD Flat Panel Monitor

1 Answer

Wide vertical black and white bands

Came back from out of town and docked my laptop so I could use the monitor and an outboard keyboard and mouse. Dell monitor comes on when I tell it to clone to the laptop monitor but there are 2 wide white bands and 2 wide black bands across the screen. (vertical bands black, white, black white) I know the power had been out at some time while I was gone but everything else (keyboard, mouse, printer) is working. Is my monitor fried? Thanks for any help!

Hi, You may want to try and unplugging the power and video connectors of the Dell monitor. Check for anything out of the ordinary with the AC plug and the video connector. If none, plug them back in making sure that they are snug and fitted properly. If problem persist, see if it is possible to rotate the way the AC plug is connected to the mains (sometimes this works and can be done if you are not using 3-prong or the uneven 2-prong AC plug. Sometimes, this can also be done on the other end of the AC plug). Check your docking station (though unlikely but possibly). If still a no go and your laptop works ok, then your external monitor needs some looking at. This would involve circuit analysis and component level repair. Perhaps your best bet is to have a qualified professional take a look at it. Good luck and pls post back how things turn up or if you need further information. Kind regards.

USB Mouse works, keyboard does not


You will need to update the drivers on the computer for the docking station. It will be the windows seven drivers or lack of them that is causing a failure to remap the usb ports that the wireless dongle is plugged into.

I want to use a external monitor keyboard mouse and close the lid and keep working on the computer


I'm not sure if you'll be able to close the lid because you might need a laptop that is designed to work with a docking station to do that.

Anyway, you can hook an external monitor, usb keyboard, and usb mouse to the laptop and continue working as usual.

Panasonic TC-P42S2 .. Transparent 2 inch wide vertical discoloration on panasonic 42 inch plasma, very left of the screen.


Fixed mine, myself! Black 3 inch vertical band (stripe) appeared after a cros country move on our PC-T50G10. Occasionally we would see white band with multicolored pixel width stripes. Took the risk of taking off the back to see if I could see anything. Found places on sides and bottoms where plastic like 2" flat cables could be seen. Guesstimated where the band was and found that I could flip down a black cover on one end of the cable. Tried to pull it, gently. Mistake. Realized it wouldn't one out like computer hard drive cables, so I took out the screws holding the plate on the other end (it's only an inch long). That allowed me remove the cable. Took it out, cleared away dust, put t back and closed the black over. It worked! Put the screws back in, back on and... we are happy (although I do have four extra screws!). Just be gentle.

Monitor displays wide vertical stripes/bands


That is the symptom of failed T-CON board (part of the LCD panel assembly, new panel will be needed), you can try reseating the ribbon connector on the LCD panel first.
This what T-CON board looks like:

I have a 2inch wide band down middle of screen on


1) Have you installed new drivers or software or drivers? If so, remove them and restart the computer.
2) Try applying pressure with your fingers on top of the screen. If the band dissapears or dimishes, you may have a broken screen and it will need to be replaced.

Vertical white wide band - Shivering fonts


Unfortunately that sound like a defective LCD panel. You can verify this by plugging the system into an external monitor. As long as the shimmering band does not appear on external display then it is the LCD. If it is under warranty I would suggest taking it into Apple.

unplug everything from the docking station, and press and hold the power button for about 15 seconds. Afterwards, plug in only the power and the monitor to the docking station and dock the laptop (make sure the laptop is turned off before docking and turn on after docking). If you still have issues it could still be hardware or software at this point. If you do not have issues, plug in one thing at a time to the docking station (mouse, keyboard, ect.) and restart the laptop each time until the problem starts again. this is how you will know if a device in the DS is causing the issue. if your monitor is vga (port on back of docking station where monitor is plugged into is blue) try plugging it directly into the laptop. also try plugging in the keyboard and mouse directly into the laptop (if they are usb) and anything else you may have plugged into the DS. This will be a better way of testing your devices. If all devices work fine, i would say that it could be more of a hardware issue with your DS.
