Re: audiovox lcd tv
First easy thing to try is unplug the TV from the power for about half an hour and try it again.
If no luck;
Do you get the same effect if you unplug the cable box from the tv completely? what about if you are watching something from another source - DVD player or VHS or PC or similar. Do you get the same?
Could you post back a photo of the green dots etc? may help us to diagnose the problem.
Do you have a model number for your set - it doesn't seem to have posted?

Faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.
New cable box recently? If not, your cable provider has probably pushed a firmware update to your cable box. Green screens are very common with HDMI connection. From your symptom, I am going to take a guess that you are connected via HDMI. If so, switch to Component cables and your problem is solved. It's not the TVs fault... cable boxes seem to be the single largest problem child for HDMI compatibility. I hope this was of some assistance.
You have to option in LCD Source In-Put.All LCD Have this In-Put Com posit-Yellow/Red/White (AV) In LCD Select AV Mode After That Connect Yellow /Red/White as per color pin given in your LCD. Component-Green/Blue/Red If you have Component in put in your LCD than select from source component mode for Red/Blue/Green.
That would be my solution. The trouble is either in the box or your connecting cables. Verify this by connecting the cable directly to the set. Then try a new set of connecting cables, or call the cable provider to replace the box.
I'm sure you all thought of this but if someone does not state the easy fix then the easy fix doesn't get done.
I had the same thing happen to my Sam46inch1081, it just started doing it, no slow fade in over time.
I have cable with the HD box, all I did to fix it was unplug the power from the back of the hdbox, wait a few seconds plug power back in and have it reboot. Problem was solved.
Like I said, easy fix for me, don't know if this will help you, but ya never know.
Just thinking out loud here but maybe its not your tv but some other equipment you have added to it other than the hdbox.
