Gary,

Use the size control at the bottom of the remote. It will allow you to adjust the size of each tube separately. The size control at the top will not. Push size, then push the color you want to work on.

The controls at the top are for basic adjustments you can make without entering the setup menu. The controls at the bottom (under the cover) are for setup. Use the controls on the bottom for everything except shift and blanking (if I remember correctly).

Oh, and read the setup manual again, then start over from scratch. You really have to read the manual thoroughly to properly setup a G70. I read it in it's entirety before I ever touched mine, then referred to it the whole time I was setting it up. Follow the sequence as outlined in the manual. Once you get a feel for it you probably will come up with your own methods, but follow the manual to a T for now.

PS: You already understand pin balance and key balance, so you're already 90% of the way there. I struggled with pin balance and key balance more than everything else combined.

Gary--

I feel your calibration pain.

One of the best documents I found for setting up my G70 was this one attached. Although it is for a G50, it is nearly identical for the G70.

It gives what I think is the best sequential step by step adjustment for the convergence process-- it starts on page 11 and following. I found that if this sequence was not adhered to, I could never get things to come into line and adjustment. But following this guys sequence and simple illustrations gave me a BIG help. and dialed it in.

I also think if you have not fully reset the PJ to the 120" factory settings to clear out all previous hacking and tweaking, you will always be fighting an uphill battle as well. That seems like you will be loosing progress and ground already spent, but I found it was really the fastest way to get it right from the top and going forward on this convergence sequence. You can do a full system reset by going through the advanced service mode.

Phil, I'm using the service buttons (under the cover) for this. But I can't get the green and red to line up, as explained my previous post.

Maybe I really do need to try a full back-to-zero reset... maybe there's some gremlin in there that is messing up my G/R registration, and maybe a reset might clear it up. That's a lotta maybe's but maybe it's worth a try. Smile

Gary,

I was responding to:

Hm. When I hit SIZE, ADJ G, the display says it's adjusting R G B. And in fact it does. That's common in some other projectors: you adjust G to adjust the overall geometry of the screen, and the other colors follow along. That way you can tweak the geometry without messing up your convergence. Your G70 doesn't do that??

In any case, even if I adjust G size separately, that doesn't help with the "edges out of whack" problem.

Gary,

Yes it does, but if you depress the RED or BLUE buttons, it will adjust that color only. This is true for all adjustments. Linear, skew, pin, etc.

This is why you need to start over from scratch. I'm sure it's a bit of a mess at the moment.

FWIW: I decided to do a full reset on it, so I reset it to factory settings. Which did NOT set everything to 128 -- not sure how they decide what to reset to. But I went ahead and did a setup on it. The "green nonlinearity at L & R edges" was still there, but whether due to the reset or to my improving skillz, I managed to work around it. I have a pretty good convergence and I only used zone for the 4 "super-zones" (22-25) to fix up the nonlinearity. With a bit more zone I could tweak the last few little bits but this is just a temp on-floor setup, so it's good enough for now.

BTW I tried to save the setup into all memories by holding MEMORY for 5 seconds, and nothing happened. Am I missing something?

Um, don't you HAVE to be in Service Mode to do these adjustments? I think you just get "Not Applicable!" if you aren't in service mode.

Yes, I pulled the lenses, centered the rasters, and did mechanical toe-in with those centered rasters. I also levelled the rasters by rotating the DY coils so the V SKEW is at 128, set the magnetic 4-pole to 128 and adjusted the 4-pole rings, did a rough magnetic focus, did a rough optical focus (but not flapping), and misc other mechanical setup. This is just a temporary on-the-floor setup and the mech setup (projector placement vs. the screen, etc) is not perfect, but other than that I tried to do it right.

So, back to memory: how come it's not extrapolating my settings to the other memory blocks when I hold down MEMORY for 5 seconds? (Tried it with the remote and the built-in "remote.") The manual says that's supposed to work but it doesn't.

I think I understand the basic memory model, with the working memory, the service memory, the factory memory, etc. But I am missing some very fundamental concepts. Such as: how can I select a memory block? The projector automatically selects a block that matches the scan frequency. I think if it doesn't find one in the >9 range, it picks one of the 1-9 memories as a template, copies it to 10 or above for a working copy, and then selects that. If I look in INPUT INFO I see the two lines that show the memory it picked, and the memory it's saving into. But how do I CHANGE those two memory selections to select a different working memory?

How can I copy or delete memory blocks?

What is PIC CTRL -> VIDEO MEMORY? You can select OFF or 1-10. This seems to be independent of the memory block you're using. It seems to be a stored set of the various settings (CONT BRIGHT BLKG etc), giving you several picture presets within a single memory block? Why would you want that, rather than just using a different memory block?

Sure would be nice if they actually wrote decent manuals for these things... but at least the G70 manual is MUCH MUCH better than the XG manuals!!! Smile

Anyone? Anyone?? Please help me figure out the memory on this thing!

Gary,

For my machine I have to hold the MEM key for >20 seconds before it asks to save service/registration data to all.

For memory block copy you need the newer firmware and the other service mode (enter, enter, left, right, enter). From here you can set memory load from "auto" to "manual" and command it to load from 10-99. It is quite cryptic i warn you!!

Sometimes two sources load the same user memory i.e. OTA HD tuner and XBox in my case. I use video memory to adjust the XBox signal (shift,center,size). Unfortunately you need to turn this off and on manually.

Hm. I thought I tried holding it a lot longer than 5sec but I'll try again.

I've tried to enter the "other" service mode with enter/enter/left/right/enter, but it doesn't seem to do anything. But this is a pretty recent machine so I'm guessing it has recent firmware. Do you know what rev offers the memory operations?

Still want to understand how to select a new active memory. Couldn't you select a different memory for the XBox -- hopefully simply, via the remote -- instead of using that weird video-memory feature buried down in the menu?

Thanks!

I believe the firmware required is V1.3 and above.

The XBox is the older one not the 360. I can set 480i/480p/720p/1080i through the HD component cable but apperently the output Hf and Vf doesn't change.

If I remember right...

If no memories have been saved you will see the Preset and User memories load with the same number say No 3 and No 3.

When you input another signal that loads Preset memory No 3 and it is different from the signal used during the initial convergence and registration, it should now load the next available User memory starting at 10 (assuming all user memories are clear)

The exception is No 9 which is reserved for HDTV YrPbPr through component. Only User memory No 9 loads. This is why I'm forced to load Video memory for XBox. I run HD and XBox as HDTV YrPbPr.

OK, then how do you get into the "other" mode? I thought it was ENTER ENTER LEFT RIGHT ENTER but that doesn't work for me.

Here's what I see:
Turn on.
MENU displays a single page of 5 main menu options.
Hit MENU to exit menu.
ENTER ENTER LEFT RIGHT ENTER does nothing.
ENTER ENTER UP DOWN ENTER prompts me to enter normal service mode.
Now MENU shows an "S" at the top of the menu, and a second page of 4 more menu options.
When I'm not in MENU mode, ENTER ENTER LEFT RIGHT ENTER still does nothing.
If I'm in MENU, then ENTER ENTER LEFT RIGHT ENTER doesn't work; the ENTER just selects whatever menu is selected.

How is this supposed to work??

Oh, and I tried holding down MEMORY on the internal pad for a full minute and nothing happened.

So if that's you'd use video memories for, is there at least a shortcut way to change video memories without having to step through the MENU structure? If I want to switch from device A to device B, I want the macro in my universal remote to do all the setup to do that. I don't want to have to go flashing through menus to do it. Especially since the menus remember the state you left them in, so programming an automated key sequence to dig down into the PIC CTRL menu would be ugly.

I used the internal control pad when I checked the sequence above, and when I held down the MEMORY key for a minute.
