What would cause the left half of a projection screen tv to look out of focus while the right side looks fine?
Answer:
You have something in the optical train causing a prismatic effect. Most likely some debris might be on the lens(es). Has the TV been moved abruptly? The optical assembly may have shifted and needs alignment. If anybody spilled a drink and it leaked into the assembly, a syrupy coating may be on part of the optics.
Remove the screen. Check the back of the screen for irregularities. Check the projection housing and fold path. There may be debris or film on a fold mirror. If so, clean the mirror(s). Clean the outer projection lenses with lens cleaner.
you need to have the light guns aligned
Possibly a problem with the convergence board. You need a tv tech. to check it out.
my name is michael. i work in the electroincs department at my local sears. when they trained me they pointed out that unless the rear projection is an lcd rear projection you cannot view it from an angle. angled viewing on anything else causes the sides of the screen distorted.
