Blue haze at top of screen

I have a vlp hs20 front projector. When I turn it on there is a blue haze that appears on the top edge of the screen. The haze does not go away with time. The lamp does need to be replaced but I have not done that yet. I bought this projector new when firswt releaed. I will be on my third lamp.

    Replaced lamp, did nothing. Anyone heard of Blue filters? UV filters? Two filters need replacement?

Without seeing the contamination directly, it is difficult to determine what the problem exactly is. Since the problem clears itself up over time, it suggests that it is condensation rather than contamination. Have you seen more haze when the unit is cooler? How about a test. Let hte unit run enough to clear, shut it down for a while and restart it. Does the hazee re-appear? If so, then it suggests a potential problem with one of the LCD panels. If it is the panel, then the cost will not be cheap, but that is not likely.

Try that experiment and let me know what happens.

Thanks,
Dan

    Can you respond to the questions I posed? Is there a difference in the behavior based upon usage?



    Thanks,

A lamp replacement is needed here in order for you to resolve that problem since that is being cause by a lamp that is going bad already....

Blue haze/fog all over screen


As it appears from the images that the images are fine. The sanyo PLV-Z2 is a LCD projector. So basically it projects 3 R G and B lights to make the screen. Yes it is definately not a LAMP issue. Either dust could have accumulated on the R and G panels thus leading to these prominent BLUE patches or if the LCD panels are damaged, u have to get the G or R replaced.. try running a application like Displaymate from "http://www.majorgeeks.com/DisplayMate_d4189.html" and see which of the panels is exactly responsible for the problem. I think this should sort it out.

Blue haze in top right of screen from NEC mt1075 projector


the light filter on the blue lcd panel is fried due to excessive dust and heat. clean out the projector with canned air. unfortunately, you cannot buy individual parts of the optical engine- you'll have to replace the whole thing. or live with it.

Images has a blue color across the center


Wow, 3 in a row. As described on 2 other projector issues this is very similar to those others. I'll repeat the info here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the blue color has gone out. The image is made up of red, green and blue images layered upon the screen. If the blue panel has gone out then there is nothing filtering out the red light in the image.

It looks like yours has just a secone of the panel dying or comming loose from it's connector.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

Blue splonge on screen


If this is an LCD, it could be a torn ribbon cable on the red Opitical filter. It's a pain to get to and replace. It could also be a burnt Polarized glass filter on the red channel which is a little easier to replace. Check out www.pacparts.com for parts and prices. It may not be worth repairing.

Blue "Haze" at top of screen


My VPL-HS51 just started doing the same thing. There's a lot of similar reports out there and they all end up at the same bottom line - the problem is due to a design defect in the 'prism block' (LCD panel) and the only option, other than to throw it away or sell it for parts, is to pay Sony about $2300.00 to fix it. Good luck!
