Vertical IC TDA8174 was bad, half a pix, & lots of lines, & missing
parts of the pix on top half, all vertical caps measure ok, new IC
gets hot quickly, & set goes to a line. The vertical wouldn't get
worse,
but now quickly it drops right to a line. Yoke measures 5.7 ohm. Ideas?

Dani.

Replace those filter caps, especially the one of the fly supply see how that
goes.
Oh make sure the new IC is not a fake cheap China shit one.

You likely did not find all of the caps. Look to the one in the supply from
the FBT secondary.
