It sounds like my bulb might have prematurely died.
http://www.avsforum.com/avs-vb/showt...8#post16675958

Any thoughts on where to find the cheapest replacement?
I assume there are factory and aftermarket replacements, if so, how do they compare? Does the entire assembly have to be replaced, or can a lower cost bulb be fitted to the existing assembly (I haven't looked at the actual design used in this PJ yet)?

Just do a NexTag search of ET-LAE1000.

Try e-bay and do a search or try this URL. Can't vouch for any of these sources, but these are the lowest prices I've found so far.

I thought about that one, but it decided to pay the extra 20 bucks and get it from a trusted retailer.

Been reading the boards for a while, never posted until now.
Loving my AE2000 since 10/08 never had a problem until now. The bulb is due for replacement, around 2300hrs, had to reset at around 1900hrs.
Turned projector on, and it powers up, lamp comes on, and immediately shuts down. Any ideas what might be wrong? Any input appreciated.
post #3757 of 3926
It sounds like your lamp is bad. When it gets to that point it will shut down like that. I had issues like that for a while until i figured out it was the lamp. i replaced it and there were no problems. I have Relampit do my lamp, nice guy ask for John.

Can someone please explain how to use the waveform function properly, step by step? I did a simple calibration with DVE. Is it useful to use the waveform?
Thanks.

Found out the hard way this is a bare bulb.

Did you call relampit? What happened?

How do I reset the lamp hours on the unit?
post #3765 of 3926
its on the third or fourth to last page of the manual but I happen to know off the top of my head having just done it last night:

open the onscreen menu,
navigate to the very bottom option,
select lamp runtime
hold enter (the center button) for 3 seconds, until the unit powers off.

next time you turn it on, the runtime should be reset to 0.
post #3766 of 3926
Thanks for your help. I changed the lamp yesterday and it stayed with the old numbers.
post #3767 of 3926
Ok done, it's back to zero. Thank you.

PROBLEM:
From the 200 hours, my AE2000 had developed a persistent and visible lack of color uniformity. The problem was observed as a cyan color stripe in bright white picture and dark red stripe in a black image. It covered almost the whole width of the bottom of the screen, with a height of approximately 4” (10 cm).
Figs. 1 and 2 are drawings of the problem.

(fig.1) White screen with cyan stripe

(fig.2) Black screen with dark red stripe

I realized that:
• The problem didn’t get worse.
• There was no lack of uniformity in the rest of the screen.
• It was not an input problem (it happens in all entrances).
• It was not a cable problem.
• It was not a dust problem.
• It showed in all the image modes, although less in the brightest modes (light cyan on white pictures).
• It did not disappear using the stuck-on pixels fixer.

The conclusion was that the LCD with red polarizer was not “closing” and “opening” completely in that zone. For that reason, combining blue and green with defect of red, resulted in a cyan color (instead of white), and in dark red color when the blue and the green LCDs were off.

SOLUTION:
Because I took no photos, I am posting here some of Cine4home’s reviews.
I opened my projector using the disassemble guides of the Service Manual.
Removing first the upper case, I took off the lamp: 3 screws.
Then the top cover: 8 screws.
Then the main-board: 4 screws more and several connectors including the 3 LCDs ribbon connectors. Important: take note of the relative positions of all connectors.

(fig.3) Main-board

The optic block was now at sight (see fig. 4).

(fig. 5) Polarizers -inverted position-

I localized the red LCD and, according to the Service Manual, I found two “boards” in front of the red LCD panel: the “Incidence Polarizer” and the “Phase Difference Board”. This is very important: I marked with a fine marker their relative positions (see detail on fig. 4) and only then I removed the outer board (the Phase Difference Board).
And there it was the problem!
The crystal (or plastic) is fixed to the chassis with a metallic frame. This frame holds the crystal on 3 edges (lateral and lower sides) and, so that it does not slide upwards, there are two sticky white ribbons (see fig. 5). My PJ is ceiling-mounted. Combined with heat and some vibration (and perhaps a bump on the long trip?), the sticky ribbons had loosened and the crystal had descended several mm. It was the light (or the lack of) that passes through the white sticky ribbon what I was seeing in the screen.
I put the crystal in its normal position but the sticky ribbon had left a mark on the crystal. I cleaned it with alcohol, made sure not to leave marks and proceeded to mount the PJ.
Now the PJ works perfectly and there are no more color uniformity problems.
Although this may seem very difficult, it did not take me more than 1 hour to solve it.

Thank you for posting this important piece of information, I had the same problem with the projector and followed step by step what you did. At first it was a little scary but once you do it is a very simple thing to do, precautions must be taken as you said because we are dealing with some delicate parts but easy overall.

Again thank you for your findings and for taking your time to share it with all of us.

Does this projector accept 4:2:2 or 4:4:4 or both?
post #3770 of 3926
I'm using 4:2:2, works fine.

This is a source from servicemanuals.net for the service manual but it will cost you about $16US. I have a copy and it doesn't have the specific directions for dismantling the AE2000 but it shows exploded diagrams which help, and includes part numbers for all items you might need for repairs.

Where's the best place to sell a used projector these days? I've got to unload my AE2000 with 2 bulbs now that I've upgraded. Also, what's a fair price? I was thinking something in the $1000 range.
post #3778 of 3926
I tried my family and friends. Everyone is going to get back to me. I hate the idea of shipping it to someone. When my AE2000 arived last year a baseball size hole apeared on the box. I know why the shipper double boxed the unit!
post #3779 of 3926
I just sold my used AE2000 with 600 hours on it for $1000. I guess if I had sold it a few months ago I would have netted probably $200-$300 more.

I liked the fact that the unit came doubled-boxed to begin with.

If you do sell your unit on eBay be aware of the fact that many off-shore bidders are lurking out there. These units are quite a bit cheaper to begin with in the U.S., then add the fact that our currency is about 10-20% down. It is worth it to a potential foreign buyer to cover a $100-$200 shipping fee to get one of these units used for under $1K.

Do you want to sell one bulb?
