The link you posted has been deleted, so I cannot see the picture you posted. If the sides bow in like an hourglass and the red, green and blue colors are still aligned then there is a horizontal width or pincussion problem, but if the sides bow in and the 3 colors have separated and are no longer anywhere near aligned then you have a convergence problem, both of which should be serviced by someone with experience in servicing projection TV's.

The picture on my Sony is shaped like an hour glass

There is an apparatus on the back of your picture tube called a yoke.This distributes your picture on your pic tube uniformly.If this or the circuits enabling it malfunction,then you will get distortion-namely an hour glass shape.Tv has to be trouble shooted.

Picture looks like hour glass.

You're probably talking about bad convergence. Probably Convergence power board. Only $20-$30 from encompassparts. com, if still available.

My 27 inch orion tv picture looks like hour glass

you have to make sure that if you are using external/additional speakers that you keep them away from console. I had a similar problem when I install a surround sound system in by bar and one of the speakers was very close to the TV. A good friend of mine walked in and said "if you want to get rid of that picture problem and save the life of the TV you had better move that speaker." It has to do with the magnets in the speakers.
