By focus is the set looking 3d etc--called a convergence issue---if so go into the menu with the Mitsubishi remote and see if it will adjust---if off and will not adjust in some area of the screen the set needs the convergence chips replaced.

If convergence is good and not the issue describe the problem a bit more----these sets have 3 picture tubes with lens---from rear of set (safest way) the lens can be cleaned with a lens cloth---dust on them will make the picture look darker and dull looking and usually is done one time a year--do not try to adjust anything until you try this first.

Adjust headlights


the bulbs are pre-set in focus and if fitted correctly in the head light assembly they will be focused and adjusted correctly. Try adjusting the whole head light assembly by the 3 screws / adjusting knobs at the back of the assembly to aim the head lights correctly.

I have a Simmons Model ATV 4515 rifle scope. other


Your scope has 5 adjustments:
1. Eye piece focus - used to focus on the reticle.
2. windage adjustment - should be on the R side of the scope, adjusts lateral impact point.
3. Vertical adjustment - the top turret. Adjusts vertical point of impact.
4. Power ring - adjusts the magnification of the scope.
5. AO ring - Parralax adjustment - used to focus the scope at specific distances. Most markings are not exact, you should set it at the range you are shooting and fine tune focus when you look through the scope.

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

Have a Sony KP-51WS510 with red outlines


In replacing the CRTs, there are multiple focus adjustments. The basic one first is the Mechanical lens adjustment on the CRTs, (in this case red), the second one is the Electronic Focus on the Screen/Focus Block on the front of the unit behind the front panel. The third focus and on of the most important is the Beam Centering Focus. (In this case RED CTR) It is located on the neck of the CRTs. They are the first set of adjustment rings up from the CRT Boards. If any of these focus adjustments are off they will cause a symptom like yours to occur. Normally these adjustments are made before any convergence adjustments are made. I would double check to see if the repairman made these adjustments.
I hope this helps

How to focus my Zeiss 10x40B TP binoculars


Your binoculars are known as the Zeiss Classic or what was once known as the Dialyt. They focus differently from the usual binoculars like those mentioned. The rear wheel is to focus both binocular barrels while using them. The front focus wheel is adjust the right eyepiece to suit your right eye. Binocular manufacturers take into account each eye is slightly different. To focus the Dialyt...First close your right eye and turn the rear wheel until the image is sharp in the left barrel. Leave the focus wheel alone. Now close left eye and adjust the front wheel until the image is sharp for your right eye. The image should now be clear and in focus for both eyes. It should not be needed to use the front wheel from now on. The rear wheel is what you will use to change the focus from near to far objects.

Focus not sharp


Yes, you can adjust the focus of the CRTs without causing other issues if you exercise some care in the process. There are two types of focus adjustments in your TV, electrical and optical. The electrical focus is more likely to change over time than the optical focus. That's because the optical focus is mechanical and would likely only need adjusting in the event of a CRT replacement. The electrical focus controls are located behind the front speaker grill and the front access panel. Pioneer TVs will either have pop-on/off connectors where all you need do is grab and pull, or it may have a few philips screws securing the grill. The screws are generally hidden behind the plastic molding strips just above the grill assy. (they are snap on/ pull off) There will be a small, black control assembly located behind the access panel. There will be 3 focus controls and 3 screen controls. The screen controls adjust the intensity of each CRTs brightness.

Good luck!

Focus


On CRT projectors, there is a part called a focus block with adjustments for each picture tube. A sudden loss of focus is pointing to something else, a change in the high voltage. Poor high voltage regulation will cause a loss of focus. If your loss of focus has been gradual, you can try adjusting the controls on the focus block. The focus block is usually a square or rectangular block, usually mounted on the front behind a panel or on the rear behind a panel. it will have a series of red wires coming out of it. There usually are 6 adjustments on the block, 3 for screen voltages and 3 for focus. Be sure you adjusting the right ones, they are usually labeled.

Losing focus


Usually this is a back focus problem; also called a flange back adjustment.  If the back focus adjustment is possible on this camera, zoom out wide - open iris all the way - and adjust focus and lock position.
