Question about JVC AV-27D104 27" TV
Colors are a little red, but even with bright all the way up, dark scenes, such as night scene, unable to see picture, all other settings seen normal even hues and color tones. Cannot get copy of service manual from JVC.
If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.
