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.
I have the same problem. I have an LG lcd tv as well. I have my cable box connected to via hdmi into the reciever then from reciever to the tv via another hdmi cable. I can watch tv and like the problem above see the pink dots on boot-up but I can't get the home screen to display.
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.
Turn off the closed-captioning. If it's set for text mode, the screen will blank out an area for the text to be displayed. On channels or programs where captions aren't being used you won't see any problems, but other times you'll have the mysterious black box. Many TV remotes have a single button to control captions, so it's easy to get into text mode without knowing it.
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.
This is no solution but a point in a probable direction.
A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.
