TV turns on fine, but the picture is black along both the right and left sides. Sometimes hour glassed shaped and sometimes aprox. 3 to 4 inches wide. Is there an adjustment that can be made? Need help please...

Your symptom sounds like a damaged component in the pincushion circuit.
If your colors line up in the middle of the set and at the top but the picture is concave then you may have a faulty component in the pincushion circuit. When this circuit fails the picture will have an hourglass shape to it with black in the middle on the sides, or you will see square objects as hourglass shapes.
I would recommend that you have a local service center diagnose the set for you and give you an estimate of the repair.
I have seen this type of repair run from $250.00 - $350.00.
I hope this information allows you to resolve this issue.

If the picture is in an hourglass shape this has nothing to do with vertical hold. Besides, on all these sets, the hold and parameters are all uPC controled through a firmware routine that is burned in to an EPROM.
It is obvious that there is a failed component somewhere because of the hour glass shape. The area of failure is most likely in the pin amp section. If the hourglass is from the sides, it would be horizontal pin. If it is top and bottom, the fault is in the vertical pin section.
A common cause is from a capacitor that has failed in the mentioned area. Sometimes it can be an IC or other type of component in the pin amp area, but not as often as failed capacitors.
You can take the set in to service the fault. I don't think you can fix this yourself unless you are trained in TV service and have the experience and setup to troubleshoot for the bad parts, and do this type of service.
picture is starting to curve in from the sides like the shape of an hour glass.
Is the tube shot?
is it something less costly?
YOUR PROBLEM is in pincushion correction circuit.call skilled tech to fix it.
it will not take much time.
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.
