You have a defective LCD optical block which is very common on this model of Hitachi and usually shows up as a red halo. The parts wif available will cost more in parts and labor to fix than what the set is worth.

Hitachi rear projection LCD with yellow blobs on screen


I have the same tv and the same problem, but my yellow is a cloud around the outside of the screen. My tv was recently moved, and a repair shop told me that sometimes in a move these tvs light engine takes a shock and causes a yellow "band" on the screen. I am hearing that these light engines are not cheap either. Hope this helps you.

My Hitachi lcd rear projection 50v500 television


THIS IS A VERY COMMON PROBLEM IN BOTH THE 50V500 AND 60V500---IT IS A BAD OPTICAL LIGHT ENGINE---MAJOR PART---WHOLESALES FOR OVER 600 DOLLARS!

IF YOU HAVE AN EXTENDED WARRANTY---GET IT IN FOR REPAIR!

There are already several class action lawsuits in several states concerning this problem in this model.

What happens is the lamp the set uses damages lens etc inside the light engine--the engines are now being sold on an exchange basis and are all rebuilt units---that are supposed to not have the same kind of problem as the early ones.

Hitachi 50V500 Red Spot


Deb,
Unfortunately if you're not a technician Hitachi won't even consider sending you a LE for install... They will confirm your status and have you fill-out several documents.
As to the other part of the question, the service manual won't help - there is a procedure for memory re-initializing and after performing that you still have the spot then LE is called for.. But again, unless you're a tech with those letters behind your name Hitachi won't accept the results.
That said, we have done several of these and Hitachi has been exceptional to deal with pre and post install.
Hope this helps!
