Does anyone know if the y/c delay is adjustable on a 40WH08B.
Hi again, Steve;
I thought some more about this, and
would like to emphasize some basics
that you need to be sure of before
looking for exotic options such as
Y/C delay adjustment.
Your problem was green haloes, as in
the first image on http://nl.ijs.si/~damjan/calibrate.html
What you need to make sure first is
that the set is converged as nearly
as possible, in service convergence.
On my set, a different one, I noticed
haloes only after I made the convergence
as tight as possible - only then did
they become apparent, and only later
did I find out that Y/C delay could
And, of course, leave the set on for
about an hour before doing any sort
If I remember correctly, Delta was
knowledgable about convergence on
Toshibas, and Gordon from http://www.convergent-av.co.uk/
should also be able to help.
Definately converged ok in service mode on all screen sizes for pal and ntsc.
Have orderd a DVD with component outputs to see if that helps.

yup, sounds reasonable to me: if the
problem is not spatial (convergence),
it might be temporal - timing of the
(component) signals, which connects
with the solution that worked for me
(adjusting Y/C delay).
Component output from a DVD should
also have more precise timing, and
suffer less processing inside the TV.
Let me know how it works!
I should have asked you before: how
does the problem depend on the form
of the signal? (composite, Y/C, RGB
- which one is worst?)
On my set, I noticed that RGB was
actually worse than S-video (more
color ringing around edges), so i
looked at the schematics, and saw
that RGB is immediately turned to
YUV and is then further processed
(for 100 Hz, zooms, etc.)
all sorted, new dvd with component outputs.
Picture is superb !!!!!!!!!!!!! )))))))))))
Greeeat - enjoy!!
