Hi,
I don't know what happened to my panasonic lcd projector, I was watching movie, when green vertical lines gradually appeared in the picture. They are like shadows accompanies the moving subjects. I disconnected the dvd player and tried adjust the setup but no effect whatsoever. It looks something to be done inside. Anyone knows the technical side of the lcd projector please help. Thanks.

well, I hope someone with knowledge on lcd projector can give me some insights on these. The projector was working well until green vertical lines started appear on the picture.These might be the scan lines. I was using the progressive scan on my dvd player but I have no way to know whether the lcd projector accepts the signals or not.Although previously there wasn't any problem at all.I changed to interlace and did not see any difference.
sorry KCC, can't realy help you. Try and contact Panasonic themselves and state your problem. Even if it isn't new or doesnt have a warranty, they will still help. They'll have an email address on their site, www.panasonic.com or.co.uk.
I had a panasonic projector (L592) and it started having the same problem. Unfortunately this is a problem that many of the 3-5 year old panasonic LCD projectors seem to have ... especially the model that I had. It is a defect in the controller for the green LCD or perhaps the green LCD panel itself. An semi-difficult way to test would be to switch the green and red LCD panels and see if you get red shadows or still green ones (this would help to see if it is the LCD panel or the chip). If it is a bad chip, then you're out of luck, but the LCD panel could be replaced from another unit. I think that the LCD panels are actually identical but just have different color filters in front of them, so you could probably rip any color of panel from another unit that was busted (search eBay for "parts projector" frequently and you might find one).
Hopefully it will end up being something simple, but I fear that you have the same problem that I and others have had with panasonic projectors. It's a damn shame because I really really liked my L592 - it has such a great image despite not being high def or even high contrast.

Well,you know what,I have the L592 too. Looks like this model indeed have some problems. So,Why is that if the controller chip is defective then I am out of luck? Is that it is not available no more or that it is impossible to replace? And how do you get to where the lcd panels are? I wonder if I should buy a service manual on this.
If it is the controller chip that is bad, then you are out of luck because it is soldered directly to the main board for the projector. If you take the top cover off (make sure you disconnect both the power and video inputs when you do so) then you'll have access to the three LCD panels near the back of the projection lens. You'll probably be able to tell by using a flashlight which one of them is which color. Note that it is extremely time consuming to adjust any of the panels, so switching them out is going to take some patience when you go back in to calibrate them later on.
That's all I can think of for now. Good luck! Feel free to email me if you need anything else.
