I have a diagonal narrow viewing on my screen. how do i get the full screen back. i must have hit something but i can't get it back.

If you mean the PC app, you have gone into full screen mode.
You should find a "< Back" link in the top left corner. Hitting that will restore your view to include a left side panel with Search, Messages and Active.

Could be a lens hood or some other attachment masking the field of view, but that would be obvious.
Otherwise, in a dust-free environment, detach the lens, use a bulb-type air-duster brush to blow the interior, as the CDS sensor may have something blocking its view.

FZ190: Faint Diagonal lines on screen? ' NotebookReview

forum.notebookreview.com > ... > VAIO / Sony

Hi,I think the reason for that is your tv is in auto mode in aspect ratio setting. If its in auto mode it automatically fits the screen. For instance the show that you were watching prolly was not shot in widescreen mode. Try playing something that was shot in HD like some HD channel. Good luck.

640 x 480-------------7.9"x5.9" (9.9" diagonal) 800 x 600-------------9.8"x7.4" (12.3" diagonal) 832 x 624------------10.3"x7.7" (12.9" diagonal) 1024 x 768-----------12.6"x9.5" (15.8" diagonal) 1152 x 870------------14.2"x10.7 (17.8" diagonal) 1280 x 960------------15.7"x11.8" (19.6" diagonal) hope this helps in setting up correctly

You will need a diagonal, eyepiece and a finder scope. The photo tripod is not the greatest for astronomy. Acceptable for the moon and quick views of the planets but with a SCTs narrow view, you will be constantly adjusting the tripod.
I would start with a 25mm plossl eyepiece which would provide 80x power. About as high as you can get with a photo tripod.

Be aware that the Bausch and Lomb telescopes had terrible reputation for bad optics.

Check your PC video setting, ti should be set to native resolution of this monitor for best picture and aspect ratio, 1280x1024 @60Hz

Remove the eyepiece, and look down the focuser tube. The small diagonal mirror should have the full main mirror visible. If not, then adjust the diagonal mirror until all the main mirror is viaible, and the diagonal is centered. Then the main mirror is aligned until all the images viewed are concentric, with your eye being in the middle. That should do it.

Seems there is something internally wrong in your mouse or you use the mouse on a very strange material base. I have heard that optical mouses can have strange behavior when used on glass tables or thick woolen carpets, a mouse pad would solve it. If that does not work and it's still under warranty, just ask for replacement or repair.

Hit menu go video screen settings, choose normal for 4:3 and Full 16:9 for full screen.
