I'm seeing an uneven darker blue or a haze along the bottom after I changed the bulb. Looks like a blue cloud along the bottom darker, very noticable when I first shut the TV off and it blue screens during power down. I can also see it while watching shows. WHen i first installed the bulb, there was no issue. What could be the cause?

    " Disassembled, inspected, cleaned lens and tried again. Appears to be some improvement. What makes me curious though, is the streak, or imperfection intensity varies rather than staying constant. Again, it's only along the bottom 15% of the tv screen. "

You have something on the lens. If the lens was producing excessive heat it could be the melting around the lens itself, or it could be grease from your finger that was clear until it got hot enough to cook onto the glass. Either way, remove and clean the bulb lens (the one on the bulb you change out when the bulb blows) and then re-clean the focus lens on the front of the projector (the one you turn to focus).

If this doesn't clear it up, look for damage on the focus lens or the bulb lens.

It is light engine that is going bad and causing blue haze/ clouds etc.
It is an expensive part, and I would recommend a new TV instead of its repair.
Thanks.

Take you bulb out to see if the bulb is defective in any way. If its darker then there might be a chance there might have a dark cloud toward the bell of the bulb.

Dark band on left side, Samsung HL-R5668W


the reflecting mirror is likely loose and falling down inside the light reflecting tube. you should have seen the band getting darker and larger,
the small mirror is in front of the lamp and bends the light,
remove the lamp and look down the tube (light path)

Blue area near center of screen


Uh Oh! blue screen of death. Your light engine has warped a little from overheating and is distorting the picture.

My suggestion to you is to get on the phone with hitachi and start complaining, then keep complaining until they agree to pay for it. You may have to get the problem diagnosed by a pro before they agree to pay for it though.
