Horizontal lines on 42" vizio LCD

Hi:
Yes this can be fixed, it is probably caused by a some faulty capacitors either on the power supply board or the inverter board. Have a technician come out and check the capacitors in both of these circuits.

You are having a power issue

I would try to look on the power supply first for popped capacitors that supply the 24v rail for the backlight inverter.

Having sound is a positive when it comes to repair. This means that only your screen is not lighting.

If you repair the 24v line and check the 5v feed also going to the BN_on (on) the backlight inverter and you still have no picture...you will need a new backlight inverter.

Remove the TV cabinet to expose the circuit boards and plug and unplug the connectors the main circuit board, that many times will fix the issue.

Hello! I have a 32" Vizio LCD...within 30 minutes of the tv being turned on, black lines start running through the bottom half of the screen and eventually blacking out the bottom half of the tv screen. It also doesn't have anything to do with the ratio as I have tried that. HELP!

you might have an overheating problem- make sure you have adequate ventilation around your tv

If under warrenty then call vizio!
I believe its sound board but I could be wrong.
No easy fix, the part is 220$ service is 210 a used LIKE NEW 42-50 inch is 500$ shipped !
Sorry to say this but it happened to my 50 inch just before I heard a pop then it would not show a picture and had no sound.
Call them up if your tv is less then 1 yr old!

Is the unit still under warranty? If it is i would go that route first if not, Maybe consider purchasing an extended warranty and then go from there. I hope this was helpful ... Sincerely Jay
