Adjustment to size of picture frame - model ws6680

I have just replaced the lopt on my tv but the vertical and horizontal frame size now requires adjusting. Do I need to enter service mode via the remote ( if applicable ) or do I need to tweak components. I would be grateful if you could give instruction. Many thanks

Re: adjustment to size of picture frame - model ws6680

To get into the service menu using the remote turn the volume down with the button on the front of the tv ( do not release). Whilst holdind tv vol- button press the button on the remote with a circle and three text lines for a few secs. This should let you enter the mode.

I have 2 lg repair the same trouble vertical horizontal rolling

Vertical or frame rolling indicates adjustment of the frame hold is required or perhaps there is a synchronisation fault.

Breaking of the picture in the horizontal plane is caused by the line hold requiring adjustment though the symptom can be connected with interior or exterior signal problems or perhaps a power supply fault, especially where both the line and frame are affected together.
It is probably a task for an engineer or at least someone with access to the servicing instructions.

Adjust vertical picture

Without remote control you can't. You have to enter its service mode option to adjust picture size, both vertically and horizontally. If you wish to get some details, check this link. Selecting the view option, either to Mosaic / Timeslide / Flipcard, can be selected by the drop-down list, at the top left of the display window, will make surf easy. You can also do a search, by type in the brand name / model number / IC used, in the search box at the top right of the display window.

Which service manual setting controls horizontal size?

You're discussing about the factory mode adjustments. The horizontal width adjustments will not be there. You have to adjust it by replacing certain capacitors at the horizontal output stage.

27 inch Zenith TV Vertical too big

If you are using a DTV coverter box, you may have changed the aspect ratio with your remote control. look for a button marked "aspect" or "picture size" use that to change size.
If you have a cable box, you may have a similar button.
Or you may find a picture size adjustment on your TV remote.
If you do not have "aspect" button on your remote try going to set up menu and look for picture size.
Older TVs used to have a vertical size adjustment at the back. look in the manual.
If none of the above, you have a biiger problem with the TV internal parts needing attention

Zenith tv picture is larger than screen

There are Horizontal and Vertical size controls behind the back cover that need to be adjusted using a hand held tool. This adjustment requires a trained tech. High Voltage from the set is dangerous.
However, there maybe some limited controls that may help through the on screen menu.
To get into the setup menu, you need the original Remote that came with the TV.
Hold the Menu Key down until a box appears in the corner of the screen, then press 9,8,7,6 Enter. this takes you to the service menu. Just scroll through the items to find Horiz Size and Vert Size.
Good luck

TV dropped

That's still repairable here some tips need to consider as follow:

1) Intermittent loss of syncronisation, both horizontal and vertical
The surface mounted power transistor on the teletext module requires resoldering. As there is evidence of scorching on the board the use of a more substantial component would be indicated perhaps with small heatsink
2) Picture displaced vertically, picture too high or low
This problem was cured by entering the service mode (menu then 4,7,2,5), then pressing the green fastext button to access geometry settings, selecting VP1 (vertical position) and adjusting as necessary
3) Vertical line at the left of the picture
Replace L506 on A board, replacement part number 1-407-366-00
4) Problems with screen size
Look out for 2 x 2.2uF electrolytics (sometimes red in color)
5) Vertical height oversize
The eprom was found to be faulty (nvm)

Please let me know any update.

Horizontal line in my TV.

"Guest" obviously has no idea what he is talking about. There is no such thing as "frame section" and if the vertical IC, ramp generator or vertical hold circuits were bad, you would have no vertical at all. If you mean that there are thin white lines at the top 3 inches of the picture, and the top of the picture seems folded back on itself, it means that the pump-up capacitor is going bad in the vertical output circuit. This is a very easy thing to correct but should be done by a qualified tech.

Screen Size is Too Big

There should be a vertical height adjustment control potentiometer near the vertical output IC on the right side of the PC board near the front section of the TV that can be adjusted to shrink the picture vertically. Be careful not to short anything out or getting yourself shocked in the process if you decide to try to adjust it yourself. Good luck. This chassis has also been known to have bad solder connections in that area also, so don't man-handle the printed circuit board roughly.
