Question blue vertical line

I have started seeing a blue vertical line all the way from top to bottom.. just a single one just to the right of mid-screen, I'd say.. It comes and goes.. so far it is pretty infrequent. It happens on any input from my pre-amp, so it's either introduced by the pre-amp, the hdmi booster, the hdmi cable, or the PJ.. Any ideas, folks?

I'm still on my original lamp, as well.. not sure if a blue line would be a sign of a failing lamp.. I imagine not..

How does one know that it's time to change the lamp? Do these bulbs get dimmer over time, start to flicker, or simply die out?

If the 3D is so dim that it's hard to watch, is it time to change the bulb? I need to check the hours on this unit. Is there an estimated window on number of hours to replace the bulb?

My AE7000 started flickering at the 800 hour mark. Tried leaving it in Eco for a few days and switching back, better for a bit, now still flickering. Bought it Jan 2014 so still under warranty, anyone have experience getting this resolved? Do I just call Pano or drive it my local service center?

I think I would just take it to the warranty service center. There is nothing they can do over the phone.

I am hoping that one of the experts has an answer for this relatively small issue:
On the Panasonic AE-7000:
Sometimes - I would say around every 2-3 hours - the pciture on the screen vanishes for about 3 seconds and then returns. The sound is unaffected.
Has anyone ever experienced this issue?

I'm getting sick and tired of my 7000. Crosstalk in 3D is getting worse, bulb at 800 hours start to flicker and never goes away (I'm on my 4th bulb, 800 hours, flickering again).

Does it happen with all sources? I have had similar issues happen due to a poor connection somewhere in your HDMI signal path.. try reseating and/or swapping your cables and see if that changes anything.

Thanks for the reply. Is it possible that it might be the projector or does your intuition tell you that it is HDMI based?

I also see these lines on occasion.. but generally have a blank WHITE screen whenever I start up... I then have to shut down and restart and then it works fine. Weird thing is that it did this since I bought it but moved from Asia back to the States and didn't get the chance to repair. Sat in storage for a year and then didn't do that any longer. Now after using it around 10 times, it's starting to do that again.

Must be some glitch in the projector...?

Well, anything is possible... but your symptom more likely seems to indicate a drop in the video signal somewhere along the way to your projector and thus the resulting blue screen ( is this what it does, or does it just go black?) while it syncs back up....

Screen turns gray/black NOT blue. Clue?

Not necessarily...could be dependant on what component is directly hooked to your projector...For example: when I switch channels on my Directv receiver, and i tune to a channel that is using a different resolution, there is a black screen pause of a couple seconds. When switching on my bluray player, I have a blue screen for a few seconds....I would also maybe try using the other HDMI input on your projector just to compare...

I red light comes on the projector and doesn't go off at the 3800 hour mark. You also get a warning when you turn it on. I had 4006 hours on my bulb when I replaced it. I never watch 3D. Anybody want to buy some glasses cheap?

Thanks Deano for the reply. I think I should be a lttle clearer about my issue. The dropout of the picture actually occurs while I am watching a movie. So, for example, say I am watching Netflix; the screen goes gray for about 3 seconds and then returns to normal. Sound is unaffected.
your thoughts?

Same thing....switch inputs , cables , etc just to see if there is any change... Only does it with Blu ray player?... Or cable/satellite too?... If it doesn't do it for all sources, sure seems like connection/cable issue...

Is anyone able to provide feedback on the reliability of the ae7000 when compared to the ae4000? Both similar or is one more reliable than the other?

Question

My unit started showing these blue splotches on the lower part of the projection a few months ago.

I tried cleaning the lens, replacing the lamp with a new one and cleaning the inside parts I could reach without having to use a screwdriver, but no luck... still very visible blue splotches on both sides of the lower part of the projection:



Please excuse the ****** mobile pic quality, but even at this blurred quality the colored splotches are very noticeable.

I don't know, it is like my 4 lamp on this unit and I recognize I've been using it a lot. Maybe it burnt something?

Any ideas to approach this problem besides sending the unit to repair? (a pain in the ass)

I can't say I can see the issue on the picture, but something similar was happening on AE2000 series. There was something wrong with the glue that held color filters, so they would become slightly skewed/offset from metal frame, usually just on one side. I think in my case, it was bottom side of the red filter. Do you see only splotches on random places, or is the entire bottom side also blue?

LCD modulators could theoretically get destroyed by intense heat or light, but I doubt a modern projector would be so inadequately constructed.

So, I take it that it isn't dust blobs? Or I assume that you have taken it apart enough to blow canned air on the LCD panels at least?
