The TV works ok, with exception of the HDMI ports and the Digital Tuner. The Component, AV, Computer Monitor ports all work fine. During powering up, it does take longer for the TV to be ready to operate for about 30 sec (volume control, changing inputs, powering down, etc.) I took the TV to a technician and they told me it was board that was fried, and it needed to be reprogramed too after the install. That didn't sound right. Please help.

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.

Is the HDMI port 2 work? Try to turn it off and turn it back on. If it is still not working then the HDMI ports have gone bad. You will need to replace the main board.

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 protected]. thanks, keith
SOURCE: Vizio L32 32 in. HDTV LCD HDMI input not working
I recently had the same problem with my vizeo hdmi port # 1 going bad. Tried everything to fix and called vizeo. There solution for a master reset was turn off tv and unplug from the wall. then hold down the power button for 30 secs and let go. plug the tv back in and hold down the volume down and input select buttons down on side of the tv for 15 secs. release the buttons and turn the tv on after powering down all the components connectd to the tv. If this does not work they told me you need to have it sericed for a bad hdmi input. Hope this info helps anyone out there. It didn't work for me. Its a bummer cause the tv is well taken care of and only 18 months old. Best of luck to all others.
You have several options for connecting your DVD player to your GV42L FHDTV10A - HDMI,
Component, S-Video and Composite (AV) inputs. Based on your home theater configuration, you can
decide which option is the right one for you.
connected to the HDMI input of the VIZIO GV42L FHDTV10A for optimal results.
To maintain the display quality, use a VIZIO certified HDMI cable available up to 10 meters or less.
1. Turn off the power to the LCD HDTV and DVD player.
2. Connect a HDMI cable to the HDMI output of your DVD player and the other end to the HDMI
