I have a magnavox 25 inch color tv (model 25P615-00AA), and in the
past couple of days it's started having picture trouble. Basically
the picture looks scrambled, after a few minutes it clears up (seems
to take longer to unscramble each time we turn it on). It's like it
has to warm up or something. Audio is fine. We haven't moved it or
anything, it just started happening.

Any help will be appreciated on what part may be causing this.

thanks
Randy
