Question about Konka K2386U 23" TV
Which circuit is responsible for these problem
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.
