My Z2 seems to have entered a mode whereby the only choice available on the AV System Menu is 1080i, making it impossible to access the Image Select Menu. How do I restore the previous AV choice of "auto"?
If I understand your description correctly, when comparing it with my Z2, this is a function of the input type. If you have the input set to DVI and ANY digital source connected, the projector selects the mode that it is receiving and does not allow you to modify it. The options on this menu are only available when using an analog input. Try switching to any of the analog inputs and see if the option doesn't re-appear. It seemed strange to me too at first, but it makes sense because the digital input does not require "fine tuning" to convert it from analog to digital because it is already digital and therefore the signal itself skips this conversion step and the menu that goes with it.

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.
If I remember correctly, you hold down either the power or the menu button for 30 seconds... I believe it is the power button, and it will briefly display it on the screen, but this assumes it was reset at the time the lamp was installed. The counter counts up on this model, and the lamp replace light will come on at 3000 hours. I have 2 of these units, and I have gotten at least 5000 hours out of each lamp. Toward the end of the lamp life, it may start getting dim and/or have difficulty starting, but I probably wouldn't replace it until you either notice the dimming or the lamp fails, although I've heard some say they can damage the projector when they fail, I have not had any problems.
( 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.
is this original lamp or refurbished one or compatible some thing.
how was performance of previous lamp when you pull out it? if it is still working for few minutes, you can confirm projector by reinstalling it.
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.
