Color is off with double image?


Is the image bow-tie shaped, with red, green or blue fringing effects? If so, one of your convergence amplifiers has gone bad. (Bow-tie: at least one of the three primary colors in the picture goes out to the corners, but the top, bottom and sides are bowed in at the center.)

If it is simple color fringing, with no color grossly misplaced, something has messed up the convergence. This may be caused by a strong magnet near the set (for example, a poorly shielded audio speaker), moving the set so its orientation in the geomagnetic field is altered or its components mechanically shifted (rough handling).

If a convergence amplifier is bad, replace it before doing anything else. If you just have minor fringing, see your owner's manual for instructions on using the remote control to adjust convergence. If it isn't in the owner's manual, you'll need the service manual. Caution: if you try to adjust convergence with a failed convergence amplifier, not only will it not help, but you will have a lot of extra work trying to get it back to normal after you replace the amplifier. Try a small adjustment along one edge of the picture. If one or more of the selected color dots in the convergence pattern won't move, and you are sure you are following adjustment directions, stop immediately and proceed with hardware repair.

Convergence amplifiers are usually marked STK392-nnn where nnn is a specific variant number. Two are used; I usually change both because quite a few people have changed one and had the other die not long afterwards. Sometimes there is a fuse in the power feed to these modules that is also blown. If you change the fuse without replacing the amplifiers, you'll probably waste a new fuse.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

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