What would cause my tv to have a 'shrunken' image just in the center top and bottom..looks like the Budwieser/Chevy bowtie??

go to settings you are set on 3 D.

This is a bad vertical section. Probably just capacitor(s), but it will require repair.

SMPS fault. Check and replace damaged component/s at it main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts. Do a search by type in the brand name of your device at its search box.

Check all the electrolytic capacitors.

It is between the grille and the radaitor directly behind the chevy bowtie (chevy emblem) in the center of the grille.You will need to remove the grille to access it.


hope this helps!

HI!
can you take a picture to your tv to see exactly what happen to your vertical problem!? then you can post here thanks!

Hello
You can set the picture size by remote control itself.

You can vide 480i format programmes in three picture sizes. 4:3, 16:9, and ZOOM
You can change the picture size by pressing the PICTURE SIZE button on the remote control.
4:3 Picutre size
To fill the screen, the top and bottom edges are extedted more widely, although the center of the picture remains near the former ratio.
If receiving a 4:3 programme, the image size is displayed in its originally formatted proportion.
16:9 picure size
This image displays the size of standard 16:9 with black bars at the top and bottom.
If receiving a 4:3 programme, the image is displayed with black bars at the top and bottom and stretched wider.

NOTE: If a fixed bar remains on the screen for a long period of time, the image can become parmanantly engrained in the screen and cause subtle but permanent ghost images. Never leave your TV for long periods of time while it is displaying these images.

Zoom picture size [for 16:9 formats]
The entire picture is uniformly enlarged --it is stretched the same amount both wider and taller (retains its original proportion). The right and left edges of the picture may be hidden.
OK.

Replace STK730-010 it will be located above bottom chassis on small board, will have Part number on it.
Mats has them for $5.95 1-800-628-1118 let me know if you need anymore help.

hi

reduce the resolution to a bit lower and the refresh rate to a nominal 60hz and things should get back to normal

my hunch is u r using a slightly high resolution and refresh rates

but before that try the buttons on the monitor to see if expanding the image sideways or top and bottom would help initially

cheers
pls rate if this was any help
