The screen seems like its fixing to go out! The picture starts off normal size then gets smaller and almost goes completely away!

Hau do i move the picture sidles


Not enough information...
What type of tv and model etc.

One thing you should be aware of.
If you do not have HD tv...say direct tv
then you maybe stuck with a smaller picture.

Example:
If I run my direct tv HD I get a full picture but, if
I am running it in a non HD channel...the picture
is alot smaller with the black sides and top.

The other option is on your remote you should
have buttons to control stretch etc.

Use those and see if they help.

As far as dvd"s go...make sure your not using
the letterbox versions...full screen versions should
give you ...well...Full Screen.

good luck

When I turn on my Vizio P42hd I get lines of different colors down the left side of the unit from top to bottom. Is this something that can be fixed? My email is mdrye@holtville.k12.ca.us


This problems is not causes by a person or some objects by hitting ur LCD tv picture screen panel?If,yes,by a person or an objects by hitting the picture screen panel.This tv is not repairable only can be by replaced the whole entire LCD picture screen panel only,sorry than this tv is not worth repairing.Because by replacing the tv LCD picture screen panel itself,will cost the same as a new tv.If these colors strips show up by itself,yes,tv it is repairable.The board call the T-Con decoders board is dead.This board sit right at the bottom right in the middle of the LCD picture screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-Con decoders board for the replacement.
