I own a 36" flat-face 400-series Sony WEGA IDTV
and, yes, I have the service manual.

Is that the same set you kept trying to give away
on rec.antique.radio+phono?

Are you kidding? That was an NAD MR-20A with a failing focus system.

It is a classic set, and worth restoring -- if you can find the parts needed
(most likely a no-longer-available HOT system). If someone wants it, it's
theirs for the cost of shipping.
