Question about Vizio GV42L 42 in. LCD Television
We have an almost two year old Vizio GV42L LCD TV with a green line running vertically down the left side of the display. It appears after the TV has been on a few minutes. HELP, I am going cross eyed!

If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on. If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

My 37" vizio I bought in Dec 2007 did this (green screen at start-up on all inputs). At first it went away by itself after you left the unit on for 15 minutes, but then 2 days later the whole thing DIED. Luckily Costco has a 90 day return policy on TVs.
Vizio tech support suggested this (before it died that is):
Please try to reset all setting and then to see if the problem is solved. 1. Press the Menu on your Remote Control;
2. choose Set up on the OSD;
3. then choose Reset All settings;
4. Press the Exit on your Remote Control to remove the OSD.

there are several possibilities. first if the unit comes on and the "VIZIO" light turns white, but no picture or sound, then the main control board is most likely the issue. could be the LCD control board(s) depending on model one or two. and ultimately could be the power supply on the upper side....if the "VIZIO" light does NOT turn white, the whole power supply unit is out. after that, would have to scope the circuits to find out. Seems that the control board is the most common and tends to happen on many different sizes. new board will be around $350.00. Might get lucky and find a used one, but it MUST be EXACT part or it wont work right. if you dont find one or want to sell yours for parts, id be interested in the screen. can reach me at email@example.com. thanks, keith

remove all the screws and start at the bottom and push in the tabs, and work around the edges, being careful not to pry too hard, the cover has clips all around the tv. after the bottom is free and one of the corners the cover will kind of pop off if you use the palm of your hand and lightly tap as you apply sum upward pressure.
