The 5vdc standby is workingbut the 12 and 24vdc power supply are noty running, it can be due to not getting the turn on command from the main board, or the fault is in the power supply itself, or it sensing shorted circuits in the backlights inverter board so it will not come on.
So look for PSON signal (3.3~5vdc = ON), or disconnec the cable to the backlights inverter board to see if the 12/24vdc will come back on.
You did not provide the model number so I cannot look up the power supply information.

LCD tv Vizio 42 inch has vertical colored lines completely across (vertically) the entire screen. Here's the picture: [IMG]http://i22.photobucket.com/albums/b320/Relicario/lcdtvverticallines.jpg[/IMG]...


hello imvega7, as i know, 42 inch is a plasma display TV.
Refer to your image, and my experience that symptomp because of connection between buffer PCB and panel. Some cases, dirty conection may cause this symptomp.
Un plug power cord, open rear cover, fine pcb on upper or lower panel.
unplug flat cables from pcb buffer, clean soket using a brush. And also clean flat cables using celaner or alcohol.
Wait untill that conection dry. reassembly and try it.
i hope that help you.
