AL1969W Vertical Rainbow

I to am seeing the same display on my AL1969W. White screen with vertical bands of colors as seen in your picture... i bought a new Main board and replaced it but this was not hte issue... I am guessing it is in the LCD circuitry itself. The Power supply appears to be good if the unit is powering up I assume. Did you ever figure out your issue??

Hi,

Did you try disconnecting it from the power for a few hours to hard reset the unit? Did you check the power connectors?

SOURCE: A big white vertical static band appears as soon a i turn on the power

Some of the transistors or the connection to the panel inside the monitor are damaged. There is no absolute fix for this problem.

You can try pushing on the bezel (NOT ON THE SCREEN) of the monitor at the edge of the screen directly at the lines and you may be able to push the connection back together well enough that the line goes away, but usually in desktop monitors the bezel is too rigid to allow you to put any pressure on the connections at the back of the LCD panel.

SOURCE: Vertical White Band on LCD Laptop

Your new LCD is faulty. The band on your old one is the end of it I am affraid.
Laptop LCD's although built to take a beating (or so it seems) are extremely fragile. It only take a very small drop to end their lives.

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....

The screen has colored vertical lines and becomes to a dark black band about 6 inches of width.The tv is exactly two years old by today.


My 3-year old 52-inch Toshiba flat panel TV (Model # 52RV53U, Serial # AM409000295) developed a display problem (purchased Aug. 2008, manufactured July 2008). Vertical multicolored lines appeared on the screen just left of center. The band of thin vertical bars is 5.5 inches wide. The lines are about 1/16-inch wide. They are stationary, always exactly in same place. They over-ride any other picture on the screen (no transparency). They are there all time even with no video inputs to the TV after the unit is turned on. See picture #1. The TV works well in every other respect, but, obviously, it is annoying to watch the picture with the color band blocking about 1/6 of the picture.

I already swapped out the TCON board with no improvement and replugged the TCON board cables with no improvement.

Most likely it is the flat panel tab bond failure (panel made by Samsung). Further solution updates will be on my Facebook page.

Inch wide vertical white band on my Imac screen?


If the white band appears right from start up, the display needs to be replaced, if it comes on after it starts, it is most likely a software problem.

The white screen tells me that the display cable (inside your monitor) may be unattached or broken.
The color bands if they are vertical or horizontal lines tell me that your display cable needs to be replaced.

So overall replace your display cable. If this doesn't entirely fix the problem your logic board (inside the monitor) needs to be replaced.

White screen with vertical bands


I have experienced the exact same thing. No dropping the Palm. No moisture. Just turned it on at work and it had the lines. Fortunately the data was still available for a synch. Now I am ordering a complete LCM and digitizer from PDA Smart.com. See http://www.pdasmart.com/palm-tx-repair-parts.htm for the pricing. It isn't cheap, but I believe it will fix the problem.  Let me know what solution you came up with and how the issue is now. Thanks, er
