Question about Dell E171FPb 17" TFT LCD Flat Panel Monitor

2 Answers

White screen. Faint vertical lines

Occasianally goes to completely White screen w/ soft faint vertical lines.
Usually happens after computer goes into power save, but still happens now that I disabled power save.
Powering off and on only rarely corrects it.
Leaving monitor off for an hour helps more often.

    Screen goes white at random times during start up, when it remains white no matter which buttons I press (except off/on, when it goes black, then back to white). The Windows desktop image can sometimes be seen when viewed from the side but is incredibly faint. These "white outs" happen about one in five start ups. Occasionally I can get it to work by pulling out the power cord from the back and reinserting it.



    Only once has it failed during use, at which point, having nothing to lose, I threw it onto the carpetted floor, whereup on started working again. Since then I can sometimes get it to work by whacking it VERY hard on the frame edge. I have dismantled it several times to look for loose connections but everything seems ok inside at a macro level.

Check capacitors that filter the signal from de character generator ic. Unsolder it or them if there are more than one (usually are of 220 micro and test it with an analog tester. If ok, look for the datasheet fo the IC and check if the vcc pin keeps energized when the monitor is on save mode.

Dell 1905FP powers up but screen goes black after a few minutes


The monitors inverter seems to be failing. If you look up close, can you see a very faint image of the desktop?

You should think about getting a new monitor it might be cheaper than repairing.

Panasonic ctp2780sf no picture faint line going vertical across screen


There are two reasons for this fault. A fault smoothing capacitor at the video output voltage rail, or excess of screen voltage. These lines are called 'vertical retrace lines' technically. Check this link for more details. It has a post, which have information regarding this fault. Go to older posts there.

My LTV-32w6 westinghouse powers on & has sound but displays black screen with very faint colored vertical lines. It shows like this for about 1min before it goes into standby mode & the blue power...


Depends on what is causing it...

Vertical bands of faint black are generally caused by filtering capacitors and can be found in the power supply or the 5 volt supply or even the Video processing circuit...it is not an easy task to identify the source of Video hum bars.....we also call them Jailbars.

Another problem seen is faint black lines caused by the TV set being in 4:3 mode all the time....right at the edge of where the picture ends and the black pillars begin, we see a faint black line that never goes away and is normally seen with a full screen....

That is actually image retention, but it's caused by the crystals that create the picture becoming polarized or ionized over a very long period of time....and it's not easy to DE-Polarize them !

But there are some theories out on how to do that....
Certain people suggest running the TV overnight with an ALL-WHITE picture and some suggest an ALL BLACK PICTURE...and some suggest alternating between both !!

Now, a black picture is easy to make, you just deactivate the Video Mute (blue screen) and set it to an unused Video INPUT overnight....

About the only way to make a white screen is to use the USB port for pictures and take a very bright outdoor shot of a piece of white paper that hopefully is out of focus too....That would create an all-white picture that you can plug into your TV set overnight....

Now if you decide to try this, deactivate any displays on your TV set...all you do is press the display button until the Video and/or USB input numbers disappear....

Next day , set it back to normal TV and see if it's gone or if it's REDUCED....try it again if needed, or try the exact opposite if you see NO RESULTS....

Your correct, LCD's don't burn. This sounds like a defective main control module. I would take it in as soon as possible to have it looked at.

Faint blue vertical bars on screen


What you see on your screen are retrace lines, it can happen for various reasons. Jut lower the screen voltage by adjusting the knob specified as "screen" on the LOT, this will disappear.

The faint white lines at the top of the screen is the warning that the pump-up capacitor in the vertical output circuit is going bad and the output itself is about to short out. When the TV stops working, the vertical output IC has finally shorted out. Replacing the vertical output IC, the pump-up capacitor and possibly a small value resistor next to the flyback (B+ for the v-out) should bring the set back to life.
