Guy selling one of these says the projected image is yellow tinted. Says it's
the bulb.

Is this right? Or is it more complex, like an issue with the LCD display or
other more expensive stuff?

Model XG-NV6XU.

Thanks,

I've heard this is usually caused by an aged polarizing filter....

Take the lamp out and look straight down into the reflector. If you see a
discoloration on one side of the reflector or spherical part at the bottom,
it could be the lamp. Regardless, a polarizing filter is suspect, and it
could be going bad because of the above described problem with the lamp. If
you buy it get a service manual and verify that the filter and the blue
panel are available and at what price. And buy it cheap. Very cheap.

The lamp ( not bulb ) *is* more expensive stuff, as is any other part in the
optical path. Also, service manual needed for optical alignment issues for
filters, LCD panels etc after dismantling / replacement. Needs to be very
cheap ...

It could be, but it could also be something else and even a new bulb is
close to the value of some of the older projectors. Personally I
wouldn't pay more for it than I was willing to spend on the parts it
contains for experimentation, which is not much.

i bet the LCD itself is going bad, at least what I seen in the several I
have worked on it. the LCD panel replacement would probably cost more than
what that thing is worth.

Take the panasonic PT-L592 for example.

I've had a similar case where the cause was the lamp. Replaced it and
the dull yellow image bightened and white showed as white. The seller
or his technician may have reset lamp timer without replacing the lamp.
Don't believe the "remaining hours" reported and expect an implosion
soon if u continue to use the old lamp.

Not necessarily. The lamps with the yellowing in the Sharp projectors can
last a long time in that state. The problem is that it may have hot spots
that will eat the polarizing filter and the blue panel if it has not
already.

Is this something that is simple to diagnose? I mean, upon examination with
the naked eye would the lamp, or the LCD, or the polarizer filter show in an
obvious way that it is the culprit?

The lamp is simple. The optical path requires significant disassembly then
it is simple. The problems are easily visible once you can see the parts.

Thanks, Leonard. This was the determination I was looking for. It will make
evaluating the potential purchase easier.

Enjoy,
