Hi, I have a KV-X2531A Sony TV (chassis AE-1C) which is recently
showing a lighter horizontal area on the top of the screen, a line
placed more or less 1/4 of the total screen size from the top.
It appears after 10 minutes or so, when the TV gets hot.

Actually, the area seems to be slightly distorted, as if the lighter
line is indeed the result of an "accumulation" of horizontal lines.

BTW, the TV is the same where I had the disappearing color problem,
see my old thread "Intermittent color/bw on Sony TV".
Some time ago I swapped the two variable capacitors near the
oscillators to work around the color problem, and everthing went
perfect for a while. Recently, the strange line appeared.

Today I tried swapping the capacitors back to their original
positions, but the situation is exactly the same: the color is ok, but
the line is still there.

What might be causing this? I didn't touch the capacitor values... can
their swapping be related to the new problem? Or is it a new and
totally unrelated problem?

Thanks in advance.

Ciao,

Sounds like bad caps in the vertical output stage.
