Re: SONY SL-HF100 patterning
Ben
Check all grounding areas, especially near the head amp and head drum shielding bracket and also all caps in the PSU ,Especially the smaller sized ones. This model and the C9 usually have the biggest amount that are going high ESR if it's been on for long periods of time.
The C20,30,40 don't suffer half as bad and usually only one ,that causes herring bone type diagonal patterning, as you have found.
Have seen a similar effect on a Sanyo M20 that eventually went away.
Also keep ALL modern technology OFF the top and well away from these vcr's They can and do cause picture effects to some models of TV, especially plasma and some lcd's.
