All the pictures are blurry the auto focus isn't working


You may have put the camera on manual focus. Two ways to do that.
1. There is a switch on the lens which allows you to select auto or manual focus. Be sure the switch is set on A or A/M. If it's on M, you are on manual focus.

2. In you menus, there might be a mode which is manual focus. Look in your manual index under Focus, manual. There might be a setting in the Focus Mode menu.

You can also try resetting your camera. This will put most things back to factory default mode, including the focus mode.

When playing around with controls, go step by step through the manual and try things out. Be sure to set the control you were playing with back to default unless you really understand that setting.

Is there a focus for my F19251GY TV


Hello
Yes, of course there it is in every TVs. The focus adjustment in TVs determine the clarity of the display. It is a service adjustement and if you want to adjust it you should open your TV. It can be located at the Line Output Transformer [LOT], and integrated to it.
There will be two adjustable controls can be seen on the LOT. Out of which one is Focus control, and other is Screen control. Both are marked. Normally Focus control is placed on the top side and Screen control to bottom. Both controls are interactive, that is adjusting one will effect the other a little.
If your TV is out of focus, you just open its back cover and locate the said control. It will be usually marked as focus. Adjust a little while looking at picture to get a well defined focus. For this adjustment, take its menu display as reference rather than a moving object. Adjust it to get a well defined display. Place a mirror in front of your TV, so that you can see the image on it from back side.
A defective CRT [picture tube base] "socket" may also be the cause out of focus picture. It can be located on the base card of your TV, and can be detached from it desodered. If the above said adjustments did not give any results, the CRT Base may be defective. If base socket is defective, you can hear a very slght "shhhh" noice from it as you advance the focus control. Try to find out and rectify the problem. Ok

4. If the screen still appears too bright after proper G-2 adjustment, you need to adjust the sub-bright adjustment in the service menu
control down until screen cut-off. (Service data Range is usually 21 to 25 in the Service menu, for Sony sets you first go to category "MCP2", & then adjustment item 01( "SBRT")= subright.
For electrical the focus, put on the screen a clear picture of your choice thru an input of the TV set from a DVD, then pause the playback of the DVD Look into each color and rock that color focus control back and forth (turn the control one way then the other way slowing down as the picture goes into the best focus. till the picture looks sharp do each color till they all look in focus. NOTE: it is best to look into each color tube to achieve the best electrical focus. For optical focus please follow the manual lens adjustment in the sets service manual

Focus the picture on a Model 27GT619 Television


The focus control is on the flyback transformer (Usuallly black or brown with three wires coming out of it. The bigger wire goes to the pix tube with a rubber cap at the end.) The focus control is on the side. There are two. The top is focus. Good Luck!

I have a Zenith C27A24T the picture is out of focus.


If there is no other problem, he probably touched the focus adjustment in the back of the set. Open up the back and locate the flyback transformer (part with large red wire coming out the top). There will be 2 adjustment controls on it. One should be labeled screen, the other focus. Adjust the focus until crisp.

Samsung 753S focus problem


Focus controls are on the back of the flyback transformer. You may have bumped one while the back was off. Due to dangers working on live circuits I recommend you have a service professional adjust the focus.
