You probably will need to reload the firmware check with maker for any upgraded firmware
just as a computer has a cmos program that can have problems
so does a tv or Lcd monitor with a tuner card and speakers
reload the newest firmware . the resolution scaler is overlaping
unless the two images are different colors

After turning on the tv. The screen shows up and down lines across the screen. Can't see much of the picture.


Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER


Hoping this will help in solving the problem...

I've had my Toshiba 46RV530U less than 2 years,


Diana, did you ever find a solution? My Toshiba (same model) is about 2 years old and it started getting these 4 horizontal lines spaced pretty far apart and a double image at bottom. When I lightly tap the top of the TV, they went away. But now that is not working. Please let me know. Thanks.
