Default B&O VX5500 VCR, bad picture

Hi there,
I have to repair a VX5500, which has a bad playback-picture.
I replaced the headdrum, picture is far better, but still bad.
The picture has several horizontal noise-bars.
Tape path ist clean and correctly adjusted.
Checking the FM from tape I found packets of RF-oszillations
with a level that is twice the FM level.
Packet lenght ist about 4 milliseconds.

Is there something known for that?
