Got an older projection TV that quit working. Power switch turns set on
however that is it. No sound or picture. It is a NAP PTV300 chassis. I
checked the HOT on the deflection board and it is ok. At this point, I'm
thinking something on the power board is probably gone; perhaps the flyback.
The plastic looks a bit melted and it smelled like burning plastic when the
set quit. There are a number of areas that the manual describes as
*non-servicable*. Since replacement boards aren't readily available nor
cost effective, how can I determine the flyback number and once it is
replaced, adequately set the HV?

The crt coupling/cooling fluid also will probably require changing. How
difficult is it to realign the set? Any "tricks of the trade". The
deflection board is a later model and not covered in the service manual. It
is a B10326 and the service manual indicates that this version of the board
was used in the larger (56" vs 41") sets.

Thanks for any and all help offered...
