Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---
Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.
Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.
Unfortunatley, they don't make TV sets as dependable as they used too because they don't want them to last. Your problem with this unit is that your panel is going out. Sharp does not supply panels because they are not cost effective to replace. I hope this helped your cause.
Its a Good Possibilty that its the New Color Wheel causing this,if the colors are not complete on the color wheel then that will be why you are seeing shadow on right hand side of screen.
I know I ordered color wheel for mine and had to send it back,it did the same thing.
I compared it to the old color wheel and the new one did not have Solid colors on it.
Can you see picture behind the shadow? or is it shadow and no picture?
turning off the main can be very harmful to rear projectors if you dont wait for the cooling off period, for instance when you turn off the tv from the remote, the fans inside are still on in order to dissipate the heat given out by the lamp. as a result some of the lens inside the engine may have burns-in caused by excess of heat.thus leading to shadows on the screen.
Try moving a medium powered magnet (not one for picking up heavy objects and not a refrigerator holding one) over the distorted area. If that doesn't work, try a more powerful one. This worked for my Toshiba LCD. Good luck!

This can be the sync wheel assy, failure in the drive circuit for the display chip, or an illumination fault. You will have to give the set out for service.
