Having some glitches with this set, that I acquired from Curt two months back:

1. Can't ever get it set to automatically go to the last input (Eg Input C for the Moome card in it). I always have to fire it up, choose Operate , then select input, then do the manual scroll which is PITA. Its like it loses the setting when i power it off !

2. Last night when i fed it output from my newly acquired DVDO VP-30, which was feeding an HDMI splitter (Rocketfish) the set was completely erratic trying to display an image (1080i-60 coming in on the Moome card) - relays clicking, brief image flashing, more relays clicking, mnore flashing then multiple times the set actually shut down ! It would power back on again automatically, more relays clicking, etc...more shut downs. Finally I thought I better put a stop to this lest it be possibly risk of damage. When i took the Splitter out of the equation it worked fed direct from the VP30 ... which I totally don't understand because it worked with the splitter alone just fine before (eg fed from Blue ray/HD-DVD player)... possibly something it didn't like out of the VP30 / Splitter combo ???

3. Last night when it is locking onto an image at least once i briefly get a raster that looked a heck of a lot like the "Scrambled Mess" ...very squiggly twisted sphaghetti like raster lines / bands on the bottom portion of the raster. Scared the crap out of me ! Shocked

4. Have had an issue with the geometry gettting messed up between usages ... the other night powered it up and the upper half of the raster was badly pincushioned upwards, and I had a portion of the top of the raster had been cut off and was sitting below the BOTTOM of the raster...like some weird foldover vertically. I managed to correct it using the adjustments, raster shift I think...

Could it be the battery backup chip on the system board needs replacing ?

Any thoughts / advice appreciated !

...Dave

Which version of the 85 is it?

Pressing 4 on the remote should get you straight to the MOOME card.

What code was on the rear when it shut down?

Have you tried plugging the bluray player set to 1080i straight to the projector?

There was only one version of the 85 AFAIK.

Only if the moome card is in the slot B, for slot C the '7' is the button to push, but see below.

For problem #1: there is a menu option in the setting menu called"Default input select" I bet yours at "default" now, set it to "last" instead.
#2: by the sound of it that was a sync problem (missing H sync, or twisted sync, but not sure how could that happen through HDMI / moome card)
#3-4: I guess your signal timings are on the verge, like zero proch or very minimal; so the projector has problem to identify the timings, once I had a resolution that needed +75% raster shift on one day, but needed -25% on the other day (on a NEC).

No, there is 851 and 852, if not also 850...

And no, if its an 852 the pressing 4 gets you slot C input, or certainly does in my case, as my DTV991 is indeed an 852

I did not know about the button on that machine.

The 851 is not listed in my manual for the 1351, only 751 and 1101, but that's not relevant anyway, the difference between ...1 and ...2 mostly lies in the software.

Thanks Guys,

For the auto Input select, i already tried having it set to "Last" which doesn't work either...never has even before i transferred the Moome card into it. I also tried setting it to "Default" then changing what the "Default" was to always go to Input C for the Moome, which doesn't work either.

Also, on the remote, pushing the Input select numbered key does work once in awhile, but never to select Input 4 to go to the Moome card HDMI0. That function worked perfectly on my old XG1351.... I miss that.

As for model, from the sounds of the previous posts its an 851 ?

Here is a screencap of the hardware versions

Posted: Wed Dec 24, 2014 9:14 pm    Post subject: Error code

Ok I just recreated the VP-30 ---> Rocketfish HDMI splitter ---> DTV991 connection and used my iphone to capture the rear panel code when it shut down:

It goes from 00 to FF briefly, then to 88 then back to 00.

So the error code is "FF" or is it "88" ?

I looked through all my NEC manuals and I can't find any error code reference...maybe its in the service manual (which i don't have).

...Dave

Hardware version 3.00 designates a ...2, so yours is a 852.
Error 88 is unknown, error FF is a system board error (the error code list can be found in the NEC XG section of this page, link

Abit more to it than just software,the neckboards are different, and a couple other boards are incompatible too.

I have a ...1 machine and you have a ...2 machine a we have the exactly same neckboards (except for the performance issue of course Sad), other boards might be incompatible, but actualy they are built 100% from the same components too. Smile

Which one, and which two? The HV board is different on my 852 to the 1351, and the neckboards in mine require a mod to use the same tubes as the G70, where as the older versios apparently dont.

I've had this happen on XG's and it seemed to be the system board. What would happen in my case was that some resolutions worked ok but others were flakey. So I could run 1080i with no issues but maybe 720p would be scrambled and wouldn't save the entry. Sometimes it would work temporarily so I could setup the input but even if the entry saved it acted as if it was corrupt and wouldn't use it or allow you to default to it. That made it impossible to have the pj return to it when you powered off and back ON.

Since this pj was a backup to my main one, I didn't bother to fix it but if I remember correctly, if I could get the desired resolution to run, I could save it as the default so that even though it wouldn't be able to use the normal ENTRY for that resolution, it would at least use the default settings so it could run. So I think one workaround is to be sure you save a working ENTRY as default. A friend of mine has an 1100 that has had this problem for years so it doesn't seem to necessarily be something that declines rapidly. He just always runs 1080i.

I know I could swap system boards with my main projector and it would eliminate the problem entirely. So if you can find a spare system board or if Curt can fix yours, that would be the ultimate solution. A lot of the times these issues are due to aging capacitors so it could be a matter of replacing them but I bet there's a lot of them on the system board. I don't think the system board are compatible between the 3 models. I would check with Curt as to which are swapable.
