PICTURE TO BIG AT THE SCREEN.CAN NOT SEE THE PICTERS MARGIN AT THE SCREEN.HOW TO ADJUST(REDUCING PICTURE SIZE ON SCREEN)?


1) Power your wide-screen TV on and turn to a channel that is displayed with bars on the side. You need to leave this channel on to ensure you have properly adjusted your wide-screen TV.

2)
Find in your TVs settings where you can "stretch" the picture. Refer to your wide-screen TVs owner's manual for specific instructions. Some TVs may not refer to this adjustment as "stretch." You will be able to find all the information your looking for in the owners manual.

3) Adjust settings back to normal if you want to watch a program shown in 16:9 format. Keeping the screen "stretched" will cause programs shown in 16:9 format appear zoomed in, making the picture look really different.

Wide black area top of the screen.


More than likely it's not the crt. If the picture has "foldover" at the top of where the picture is currently, then more than likely there are bad caps. in the vertical scan circuit. If not, the vertical sizing probably just needs to be adjusted. You will have to get in to the service menu to do that.

Poor picture, raster & sounds ok


If the picture is fuzzy (out of focus) it may have a focus adjustment on the flyback transformer. Possibly an adjustment available from the outside, through the back. Look for any markings on the plastic housing indicating Focus, Brightness etc.. You can use a small screwdriver through the labeled holes in the case to make adjustments.
If the picture is crisp, but faint or the colors seem washed out it may be the tube is at it's end of life or needs to be rejuvenated. TV shops can rejuvenate tubes but it's not cheap.

You probably have a component breaking down on one of the circuit boards. It would have to be checked out to find out which one. Stargazer

Tv showing blue screen with flyback lines sound ok


Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket

Slanted picture


Your deflection yoke (a coil around the neck of the picture tube) must have gotten turned. Your can turn the picture upside down by rotating this coil. If your set is in warranty, you should return it. When this "yoke" is adjusted the color is affected too. If you try this yourself you'd void the warranty and mess up your color. Stargazer
