    Screen jitters since moving TV to new house. Used to settle down after 10-15 minutes of warming up, but now it just keeps being all jumpy. The menu options display perfectly, so convergence circuit seem to be ok. Could this be a problem with the input board? Please help!

    I am also having the same problem. Other than when first turned on when the picture is completely scrambled, the flutter seems to be dependant on the image (color / brightness / both) the TV is trying to reproduce. Also, the Auto Focus feature has reported a failure every time it is used for years now.

Screen too large for pc

Right-click on an empty area of your desktop screen.
Left-click on Properties at the bottom of the drop down list.
Left-click on the Settings tab.

Under the subheading Screen resolution in the middle, does it state
1400 x 1050?
That is the native screen resolution.

If not;

1) The down arrow with the green tip, and green 'cap', is a Slider.
Left-click on it, and hold the left mouse button down.
Now slide it to the left, or right, until 1400 x 1050 appears.

2) Also;
The Color quality to the right is supposed to state -
Highest (32-bit)

If not click on the blue down arrow to the right, and in the drop down list click on -> Highest (32-bit)

Go to the bottom right, and click on Apply.
Now go to the bottom right, and click on OK.
A small window may come up, and state that these settings will take effect, unless you do not want them to.

You want them to. Do nothing, allow the countdown.

My iphone wont respond to my touch in the bottem halk

Have you tried doing a hard shut down? Hold the silver button down on the upper right corner and also the home button (center,bottom indented button) together for about 10 seconds. the phone will completly shut off. then wait about 10 seconds and hold down the upper right hand button until the apple appears on the phone then release the button and wait (20-30seconds) . Doing this usually solves all my issues with my iphone when it gets locked up like this.
