I have a shadow on the screen in the bottom right hand corner what could the problem possibly be.

It sounds like something has fallen or crawled into your tv. Unplug unit and remove the panel on the rear bottom. Now remove the upper part of the rear cabinet if you cannot see the problem. You will probably find something on the lense blocking the light. This would be a good time to clean the lenses. Using a soft cloth and windex, spray the cloth then gently clean each lense using a circular motion. Do not wipe until dry as you may scratch the lense. Do not spray the lense as you will cover critical components with corrosive cleaner. Do not push hard or disturb any lense adjustments. Reassemble unit and your tv should look as good as new. Let me know how this works out. [email protected] .
