<!-- from fixya rte -->Tv out of focus not focused - Sony KDS-60A2000 60" HDTV

Focus or convergence, the two get mixed up a lot-focus on the model listed here almost never needs adjustment at all.

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

Remove unshielded speakers or other metallic objects near the TV. It can cause picture distortion.

1. Tune the TV to channel or cable program.
   
2. Run the TV for at least 30 minutes.
3. Press FLASH FOCUS on the front panel of the TV.
4. A cross pattern appears and FLASH FOCUS begins to
   work. The adjustment is completed when the cross pattern becomes white and you are returned to the program you were watching.

You cannot perform any other functions until FLASH FOCUS has
completed its cycle. If you perform any other operation while FLASH FOCUS is in progress, FLASH FOCUS operation is canceled.

Does anybody know how to fix this?

Replace the convergence Ic's with a kit that is available through your local parts distributor

You must replace all resistors in the kit
If you are not good at soldering and de- soldering have a local tv shop do it for you

Good luck

Focus adjust is located on the neck board or on the Flyback transformer, another fault is dirty spark gap inside the CRT socket

if that doesn't work it will need new convergence IC's put in as well as a resistor or two

electech

Focus control is on the Flyback there is 2 adjustments one is screen drive other is focus turn it untill you have clear picture.

What is the set doing or not doing?.....Why do you say the focusing coil ?............What is a focusing coil..........?
Please provide the service # off back of TV........T.
