Words at top and bottom of the screen on my Sony rear projection tv are arched. Also some ghosting of images?

SOURCE: Blue dots on screen plus ghosting on screen

The optical block is defective. Contact Sony support. Sometimes they will warranty these even after the 1yr warranty has expired. Have your model and serial numbers handy.

I strongly urge you to save the web page locally on your hard drive or print it out and place with the tv manual....

Good Luck..

sounds like bad convergence IC---not uncommon on this set-both convergence IC"s need to be replaced and the set adjusted

Thats caused by a convergence failure. The Sony type 1 convergence repair kit from www.tvrepairworld.com will usually correct that issue the kit contains the components and the CD with repair instructions so you can repair yourself.

Testimonial: "This is by far the best response I have ever gotten on any question. Clear, concise and directed me to the source I needed to fix the problem."
