Hi,
Since nobody seems to have a Service manual on this model, perhaps I can go
a different route to find the correct value of this zener. I'm 99% sure it
will fix my problem, but, I don't want to put the wrong value in the ckt.
If someone has a similar service manual for a Mitsubishi big screen TV, that
uses a TA8739P for a deflection bus IC (in my case it's designated as
IC501),......please check off pin # 13, and see if there is a zener to
ground.  That should be the same zener which I desperatly need the value of.

I spent some time on a Google search for a data sheet on this IC, but, had
no luck getting into a Jap site, without signing up for a password. I don't
care about joining that site.

TIA
LLW

>Hi members,
>I need a part number, or the value of D-442 (it tests leaky).
>It is a zener diode. The only numbers on the part are: 3-0B1.
>Also a scan of the vertical output ckt. would be helpful, or if someone
