Faint Blue Line Follow-up Question for Maddogmic

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....

how it looks. Is ther any text?

The water line is broken somewhere from the water dispencer all the way down to the water valve. I usually find that it is broken next to the water valve. Hint: Water valve is blue and located behind the fridge in the compressor department. Water line is 1/4inch clear tube that is probaly now a "yellowish" color. Easy to spot, easy to fix, especially if located next to water valve...

I have a toshiba plasma 1080p thats all I know, I see the line the clearest on the blue screen, you know when you change to an imput that has nothing using it, and when watching tv or games a very faint yellow line you gotta really focus on to see. But I wanna make sure this is not gonna get worse. Thanks for your response let me know.

Try re-installing the printer driver it might be caused by a virus... if not then you need somebody to clean your printers head mechanism.. the blue cartridge might have messed an ink to its circuit.

I had the same problem with my sony KP-57ws500 rear projection tv. To solve this problem all you need is a flat and phillips screwdriver. Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up. I'm not a technician but i read up on it in a repair manual and it worked perfectly and saved me a $100.00 for a service call. It took about 10 minutes to do. I also have a friend who expiernced the same problem with a different model sony projection tv and it worked for his also. Apparently this is a common adjustment that needs to be made espicially if the tv is moved.
