The picture on my Sony is shaped like an hour glass

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

the sony service menu can be entered by pressing "display" "5" "vol+" also the diagnostic screen can be reached by vol- instead of + when you are in the service menu the number buttons navigate it its a little tricky at first but as long as you dont hit enter before you exit if you mess up it wont save just make sure if you fix it you save it by pressing enter

It more like the tuning capacitor(s) that is connected to the HOT that is defective or a cristalized/dry solder joint nearby the flyback transformer.

If you are not familiar with electronic repairs take it to an authorized repair shop.
To get a service manual and try by yourself see link

A common fault are some of the electrolytic capacitors failing in the pin cushoning amp section, and probably in part of the scan amplifiers.

To service this will require the proper training and set-up to troubleshoot the set.

Take the set to a service center for an estimate. The cost can be at least an hour or two for the labour, and then the cost of the parts on top.

can you put it other way i did not understand what you want to say & que is not complete.

picture is starting to curve in from the sides like the shape of an hour glass. Is the tube shot? NO. is it something less costly? YES YOUR PROBLEM is in pincushion correction circuit.call skilled tech to fix it. it will not take much time. good luck.

Big cap in the regulation ckt is bad. Depending on model could be various values, a shop could use their ESR meter to find and replace it.

You have a PIN CUSHION problem, is usually a bad capacitor or open resistor in the above cicuit. Check all the caps around the horizontal output transister for ESR leakage.

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.
