Re: picture not centered and not stable

I suggest you take your TV to a repairman. The TV will need to be opened up and some adjustments made to the board.

Is there a focus for my F19251GY TV

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

1st off the convergence is digital on these units when it takes a major change it means there is a hard ware failure
there are a two ics and some resistors that usualy need replacing
adjustments there made through the consumer menu.
adjustments in the service menus are for touch up or a corrupt DCU thats failed and needs to be reset up and the centering magnets on yokes are set for sharpest ctr point of focus .

Focus and Screen. The focus control may help, just like focusing a set of binoculars or an old camera. Watch the picture on the TV, using a mirror can help and make an adjustment until the picture is as clear as you can get it. If it still is not clear it may mean that your picture tube is weak.
If you can avoid it, don't touch the Screen control. If you have, let me know and I can advise you on the proper way to adjust it.

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

When you have the back off, look for the flyback (high voltage) transformer. This is the part that has the thick red wire protruding from its top which attaches to the top of the picture tube with a suction cup. On the flyback there are 2 controls, the bottom one is screen and the top one is focus. Turn the bottom control (screen) down (counterclockwise) until the white lines go away and the brightness looks normal. Then turn the top control (focus) until the picture is nice and sharp. If the F connector has been pulled out and the TV has RCA (red, white, yellow) jacks, use those jacks and set the TV to INPUT.

This RCA set uses the CTC187BD chassis. Look on the back of the set and to the right of the cable connector you will see 2 controls sticking out, one on top of the other. The top control is for focus and the bottom one is screen, or overall brightness. If these controls have been turned clockwise then you will have a bright, fuzzy picture with white lines (retrace lines) through it. Tune in a channel with white letters on the screen and turn the top (focus) control until the letters are crisp and sharp. Go into the menu and turn the contrast and brightness all the way down, and then turn the bottom control (screen) until you can just see the picture, just above the point where the picture is too dark to see. Go back into the menu and reset the contrast and brightness and the picture will be back to perfect.
