Question about Sanyo PLV-Z2 Multimedia Projector

2 Answers

Blue haze/fog all over screen

As can be seen from the pics, my PLV-Z2 has acquired a blue haze/fog all over the display area. It started out a few weeks back and gradually grew and shifted position until it has got to the size it is today. My lamp has an astonishing 5027(!) hours on it (all in Eco mode). I was initially quick to condemn the lamp but it is still very bright (not dimmed one bit!), and aside from the haze, the image is fine.

On close inspection, some areas have lots of little grouped blue 'pixels' as well...







Does anyone know what the problem is? Does it need to be serviced to have the panels cleaned...?

Thank you

    If any of the panels need to be cleaned only, how much would a service engineer charge?

    If, as a worst case scenario, all the panels need to be replaced, how much, also?

    Thanks

As far as the blue haze and focus goes, look into the blue lens . If the coolant is cloudy or has debris floating in it, the coolant will have to be changed and the lenses and crt face will need to be cleaned. Coolant can be ordered from any electronic distributer

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 diust specs constellation like!


If you are seeing the "spots" when a black screen is projected, the problem is likely to be scattering caused by dust on the lens. If you can get at both ends of the lens assembly, clean both sides using lens tissue. If the spots are seen at all times, there may be damage to one or more of the LCD panels.

Please update this with your results of the cleaning.

Thanks,
Dan

Hey there, my Sanyo PLV-Z2 was starting to have blue dust on the image, so i decided to clean the lens and remove the lamp for inspection ,everything fine , but when i reinstalled my lamp the blue had went...


( hope this doesn't sound too simplistic, but go back and check all your connections.
Take the cover off again and make sure that the main circuit board on top is pressed on tightly in the area over the right-hand back side because there are two connectors there. Also, there are several other connectors that should be checked--two on the left side, and one just underneath the left side. Those are all the kind where several wires enter a small, hard, plastic rectangle that then plugs into a little socket.

I have the same model projector, but my blue lcd panel is burned out. The other solution I can offer is for me to buy yours from you and use it for parts in mine. Good luck.

DVI will not recognise now ?


Presumably, you're going directly from DVI port on computer to DVI port on Z2?. Here is a Q&A list based on all the possible sceanrios for this hook-up...

Q1: Is it DVI-D or DVI-I (with unencrypted DIGITAL output from graphics card)?
A1: Choose 'Input 2', then 'RGB(PC Digital)' on Z2.

Q2: Is it DVI-D or DVI-I (with HDCP-encrypted DIGITAL output from graphics card)?
A2: Choose 'Input 2', then 'RGB(AV HDCP)' on Z2.

Q3: Is it DVI-I or DVI-A (with ANALOGUE output from graphics card)?
A3: Choose 'Input 2', then select 'RGB(Analog)' on Z2.

After making sure the correct 'Input 2' is chosen to match the signal coming from the card's DVI port, make sure your card is outputting a suitable screen resolution that the PLV-Z2 can display correctly, e.g... 1280x720 (native, and preferable!); 640x480; 800x600; 1024x768 (choose this if you don't have 1280x720); 1280x1024, etc. Also, if you have multiple refresh rates availble for the resolutions, choose 60Hz.

You should end up with an image.

VT45 Projector: Blue pixels throughout screen


If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

So, the problem is in the cable - solution is replace cable.
