|
Hi all,
Any idea what would cause this fault? The manual states it's a POW03(70) but don't know what that means.
The projector seems to have reset the memory as I have to do the conversion all over again for both HDMI and RGBHV inputs. Nice...
Anyhow, it this anything to worry about?
Thanks,
Gary

Do you still have this problem?

Only once. So far, so good. I have heard that if it came in once, it will likely happen again.

Sounds like your Dallas chip is going. Do you still have your serial number as well as tube and chassis hour counters in the service mode? When the Dallas chip goes these will be lost.
You can use the same chip as in the G90. If you want to retain the above data you need to copy the old chip to the new if the data has not already been lost. Or you can hex edit the info back into the new chip.

Not sure why you would think that Craig. When an error code is triggered it can clear all previous data.

You will NOT loose your serial # by replacing the Dallas chip (actually an ST Micro part, if factory original), as this number is stored in the configuration PROM. You will, however, have to do an "initial" factory reset to initialize the new Dallas chip with the PROM data (otherwise, you'll have an all-zero serial).
If you loose your serial number after replacing the Dallas chip, you have not performed a proper reset of the PJ.

Thanks Craig but you guys are talking a foreign language to me. The serial number and tube hours (didn't see chassis hour count) are still there.
You know, I'm not a betting man but I'd place $ on this happening again throughout the Christmas holidays with a room full of people...

I have honestly never heard of an error code clearing geometry data. Do you have some other links or info on this.
I could see some reason for this happening, but I have never seen a set do this before from an error code.

Yeah, you're correct. On the G70 you don't loose your serial or hour counters, that's just on the G90. If you want to keep all your geometry and greyscae data you should copy the old Dallas chip though. Though you can write down greyscale data easily enough.

See bottom of page, first note.
It is somewhat vague however the possibility is there. I have never seen it myself either but I also dont believe the memory chip would cause a code 23, but we all know how these devices can create very strange outputs, so I guess I really cant say the chip definitely cant cause it either.
However I do agree that the chip should be upgraded to the Dallas one though. 
Also note that code 23 is POW3(50)....50v line.
Gary, where did you see that code means POW03(70)?

I found it on the outside of the aluminum access cover - the one that provides access to the tubes etc., it has a factory printout of error codes 20 through 40 with error code 23 listed as P03(50).
Maybe I should shoot Curt a pm. He sold me the set which I think is an awesome projector. I'm not too worried, but don't really want any surprises with a room full of friends.

I think they're talking about the YA/YB boards which are the back of the PJ, right behind the Blue tube, and act as the control module for the PJ . There's some chips on there which are known problems with the G-series.

I'm pretty sure that's a safe bet

A fault on the 50V line means there's either a fault with the power supply that drives the 50V circuit's in the PJ OR one the devices on that line is drawing an incorrect voltage. The power supply boards are behind the red tube, under the metal cover. Take a careful look at the GB board, I had one of these fail and I was getting either a error 23 or error 33? can't remember.
