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.

Try resetting the TV by holding down the "up" button on the remote (with the TV powered on) and then, while you hold down the up button on the remote, hit the power button on the TV. This should do a "factory reset" which will wipe all settings in the TV. There is no reason why the TV should not "remember the last input it was on when it was ;last turned off. Also be sure that the TV is not plugged into a switched AC outlet, like the outlet on the back of the cable bix. The TV should be plugged into an output that receives power at all times.

Had the same problem.
Fixed by unplugging everything from the power source, leaving for 2 minutes then plugging back in.
Works fine now.
