The manual says this is "Abnormal in the 115 V Line". I just moved it to a new location, mounted the projector on the ceiling and was playing with the picture shift, etc, all was well. I came back home to complete the set up for sound on my system and replace a bad HDMI cable. When I was done, I powered the G90 up and turned it on and started getting this error code. This happens with the HDMI in or not, the Fury board in or not, etc. I just immediately displays the code and shuts down.

Does anyone know anything about this?

Thanks,
Rick

I remember a while back some had a shutdown/error code on their G90 after making adjustments and it was an extreme setting causing it. Is shift the only adjustment you made? Why did you have to shift it?

I adjusted shift and size. The reason I did that is I had this installed in another home, moved and wanted to set it up here. Problem was the ceilings were a little lower here so I installed the drop down screen into the ceiling and also sunk the projector lift into the ceiling to get it up as much as possible. When I did that, the image was low for the screen so I adjusted it up, it is at Vertical Max on the shift adjustment but that's all the changes I made. As I said, it was working so that I could do that adjustment and actually put a DVD in to check the picture before I got the cables for sound, etc. That all worked fine, got a good picture, stable, etc.

When I came home to hook everything else up, I started getting this problem.

This morning I fired it up and the error code changed to 63 which is "Abnormal in the 50 V line"

Thanks,

Did you try reseating the YA board?

No, I am just starting to try to get the unit open. I downloaded the service manuals and am trying to figure out how to get the thing opened. I'll work on that.

I just turned it on again and it went through the 5 minute warm-up without failure, then I turned on the DVD and got a picture for about 3-4 minutes and then got the 63 code again.

As soon as I figure out to get the covers off I'll locate the diagram for the YA board and try that as well as inspect the other boards reseating what I can. I'll know more about the guts after I poke around.

Thanks.

OK, I'll try that now (assuming it will stay running long enough, I'll get back to you.

Worst case you can send me some boards to test and repair. I have a working G90 chassis here.

I just did what you said and reset the vertical to mid range (125), it ran for about 2-3 minutes after that and then kicked out with the 63 error. Let me get into it and check the boards for seating. This unit was crated and shipped with my furniture when I moved from the west coast to the east coast so it's possible it dealt with some vibrations, etc on the cross country trip. Got my fingers crossed and if that fails I may take you up on your offer.

Jeez, I am having trouble getting the box opened. I seems like the back panel where the mesh is covering the fans should just open but I can't find a release and don't want to force it. Do the side covers need to come off to get at the back cover or am I missing something obvious?

Update, I got the box open, vacuumed and reseated every board I could get at, well most, some I didn't want to venture into because of location. I turned it on and this time it lasted ALOT longer. After the 5 minute warm up we watched it for about 10 minutes before it coded with 63. Coincidently, my girlfriend turned on the jets on the hot tub around the same time it failed. So I wonder if I may have a line voltage problem? We're going to experiment with that and if that seems to be the issue I'll get an electrician in here to take a look at my service. I've only been in this house about 6 month and we did see some unexplained electrical anomalies so I wonder....

I'll keep you posted but would be interested in what you thought about this possible cause.

Thanks,
Rick

I'm back (unfortunately).

The projector had been working great, watched alot of movies but my new installation needed some tweaking so I realigned the projector and began reconverging everything.

In the middle of doing some focus work, it just shut down with the 89 Error code, from the service manual this says:

"This error code comes from the EBH board. Failures around OUT/Mg might be considered. Refer to protect items for POW3"

Looking at protect items for POW3 they say:

"This protect works when the 50V line of the power source has dropped. This line is used on DC/EBR/EBG/EBB boards. There are two possible modes for which this protect works. One is the case of a failure on the OUT circuit of one of these boards. The case can be readily found out because the error code of each board is displayed simultaneously. Another case is caused by excessive Reg/Mg compensation. In this case it is necessay to look at whether the Reg/Mg compensation wave forms are normal. If they are abnormal look into DA/DB/DD/DE board or the YA board."

Interestingly the POW3 (63 code) was one I was getting awhile back and it just went away.

I've been doing alot of adjusting but don't think I am at any excessive settings, however it's possible. But I cannot even check them since the projector only comes on briefly before failing with the 89 error.

Any help available for this from anyone?

Thanks,
Rick

On the EBH, disconnect CN137, CN138 and CN139 and try power on and see if you still get the code.

If it stays running reset you focus to neutral and shut down. Then reconnect the wire harnesses and see if it stays running.

Thank you! I did just what you said and now it stays powered up.

So am I to surmise that I had some extreme adjustments that the box didn't like?

I'll go ahead and run through the focus process again to see if it recurs.

As I do the focus (and most others), it's not always obvious that I am set (depends on other focus settings to get it close) so I tend to run it up and down from min to max to ensure I am seeing what occurs as I run through the scale.

Is that not a good thing to do? I guess I'm asking could the extreme I hit when doing that actually cause the error to occur?

Thanks again, I'll let you know if it happens again or not.

It just kicked off again as I was adjusting the MG green focus using the ME pattern. I was adjusting the middle screen (ALL) when it occurred.

When you say set to neutral, what I did was go in, set to MG focus, hold the reset down for 5 seconds and say yes to resetting the service data and then again to the factory data.

Is this the way to get back to neutral or are you saying for me to reset all the values for each focus item to 128?

Thanks,
Rick

(1) I would not run the adjustments up and down to the extremes but up and down to get a feel for focus is fine.

(2) I meant setting your focus adjustments to mid range, which ever way you usually accomplish.

(3) Are you following the focus adjustment procedure in the manual?

(4) What is the focus number when you are adjusting it that it shuts down?

RickNa · Joined: 04 Mar 2010 Posts: 45 Location: Rome, NY

I was able to run through the process without it shutting down, I reset every value manually to 128, adjusted the lens focus manually by turning the focus yoke, got it as close as I could and then went in and programmatically completed the work.

It stayed up all through the process but I have two problems left:

1) I can get red and green very crisply focussed but cannot get the blue good, especially at the edges, the controls don't see to affect it as well as it does the other colors. With that I get some character shading on the lower screen and the sides mainly because the blue focus isn't as pinpoint as the others. Any ideas?

2) I save all the changes to memory by holding down the memory button for 5 seconds and save to either registration or focus data but it seems when I switch inputs it comes back a little off, covergence-wise. I believe I am doing the right process.

I have a 5 BNC hook up through a scaler on Input A and a Moome HD card on Input B that I run my Blu-Ray directly to.

I'll keep reading the manual but I don't understand why it seems to "forget" some of the convergence setting I put in when I switch between inputs or also when I power down and back up.

In any case, thanks for your help, you got me back up and running at least.
