SOURCE: Verticle line down the middle of lcd monitor.

This is a common problem with LCD screens. It is pixel line damage and the screen is permanently damaged and is not repairable. It will probably get worse. The only answer is to replace it

Press the Menu Key on your remote. If your menu shows clearly on the screen, then there is a problem with your source.

try you contrast and brightness levels, if that doesnt work maybe your AV jacks arent all the way connected, check your connections on the back of the tv

Paul,
If both cylinders appear to fire when the pistons are at the bottom, could you possibly have the wires on the wrong cylinders?

Hello..Toshiba 51HC85, 2005 model. Turn on TV and verticle wavy lines appear until TV is warmed up completely. After warm up the picture is great again. Any ideas?


I've had the same problem for about the last 6 months. My workaround which was to leave the tv on 24 7 and just turn off the TWC service box. But now the symptoms are vertical dark lines going all the way across screen. My guess is that it will cost more to fix than worth it. I paid @$2000 for it new in 2004. Technology has gotten better so I may just go out and get a Samsumg for considerably less and be way better off. None of Toshiba's products had done well for me. 2 laptops, 3 tvs, etc. have taught me this.

Dark horizontal line scrolling up from bottom of screen


if you are using a cable box .. then disconnect everything that is feeding signals into the tv ... then get a signal from some other source (like off the air antenna or video camera) ... if the tv still has the dark lines then you have a bad primary filter capacitor in its power supply .. if it works ok off the air and only does it when the cable box is hooked up .. then the cable box has an open primary filter capacitor . ... the dark horizontal bars you see is ripple from the rectified AC power that is not properly filtered ... if the TVs verticle scan rate is 60 hz and the full wave rectified AC amounts to 120 hz ripple then you will see two dark bars across the picture ... since the two signals are not syncronized then they will slip in phase with respect to each other .. thus the constantly moving pattern ..

Verticle lines on screen


This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg

Sylvania 6427FF TV displays wavy verticle lines at top of the screen.


I would suspect defective filter capacitors in the sweep circuits as well as the power supply source voltages.
