Question about Hitachi 55VS69 55" Projection HDTV
55VS69 is a LCD rear projection set---if you have blue or some other
color discoloration in some part of the picture most likely you have a
damaged optical light engine.
This model used two different ones--It is an expensive part as one wholesales for about 550 and the other about 600 not counting major labor to replace.
If you have an extended warranty--get it in and fixed.
The reason this happens in some sets is the Lamp used for the light source creates a lot of heat and can damage the lens/baffles inside the sealed light engine.
Blue is the most common as that part of the engine is usually closest to the lamp.
The set shines the light from the lamp into the engine and signal etc is injected and at the top of the engine is a 3 inch lens that projects the picture into a mirror which puts it on the screen.
Some of Hitachi's earlier sets are now involved in class action lawsuits as they had a red oval in the middle of the screen--red was first in those models--some Sony and other sets have had the same problems.
