| Posted: Sun Jun 01, 2008 5:48 am Post subject: G70 will not enter 'Service Control' mode |
|
|
I have little experience and even less knowledge.
The unit has the control panel that is 'attached' and a second 'remote' that has the command switch I can switch the unit on and off with either control.
I cannot get the unit to go into 'Service Control' mode, and it powers up when I switch the AC switch to the on position.
I presumed from some of the text in the manual that the unit wouldn't power up until you pressed the 'on' button on the control panel, so I had the thought that these two things may be related.
" Enter - Enter - up - down - Enter" isn't doing a thing for me.
Any advice ?

Is the menu showing when you tried this. If so, try it with no menu items showing...should work.

Zebu had the right answer, when I pressed the Status "ON" button, I was able to enter the "Service Control" mode.
THEN, when I started trying to reset the registration to factory default, it displayed "NOT APPLICABLE" across the bottom of the screen.
More help...???
Thanks to all,
Alan

I'm still wondering about the whole "powers on with the main power switch" issue. That still the case? That's not right.
As for the other issue, are you pressing "zone" for instance, then pressing reset?

|

Mr. Crabb,
This evening, after I read Zebu's reply, I went to the unit and it powered up normally, so I'm thinking that the fans came on last night, because the unit was warm, had been operating for a while.
Restated, tonight, when it was cold, I started it with the "ON" button on the remote.
Thanks so much for the "ZONE" tip, I'm going to go try it right now.
Alan

Mr. Crabb,
I Power the unit.
Press the Status "ON" button
Enter, Enter, Up, Down, Enter, then select "YES" and press enter again.
THEN if I press "R", "G", or "B" at the bottom of the remote I get "Not Applicable"
I pressed "Zone" and got the same message.
I pressed "Reset" and got the same...
I appreciate all help.
Alan

Weird. It sounds like you're really not in service man mode. If you press "MENU" after you should be in service man mode, is there a small "S" at the top/left of the screen, above the "menu bar"?
If you're really in service man mode, any of the buttons along the bottom of the remote (size, lin, key, pin, bow, zone) should bring up that mode with an internal test pattern on the screen. Is that not happening? You just keep getting "not applicable"?

It means the PJ turns on as soon as it senses AC power. i'm not 100% sure but I thoguht I saw the same option in the G70 menu's?
AFA the "not applicable" thing I believe the first time I treid to set-up a G70 i only saw that mesage about a thousand times

|
|
I entered "Service Cotrol" mode, then pressed the menu button, and there it is, an "S" in the upper left corner of the screeen.
So, I turned off the menu and when I pressed the reset button, or anything else that would be a service function, I get the "Not Applicable" message.
If I have to see it a thousand time, I have about 985 to go....
.....My aim here is to reset registration to factory default. Any ideas ?
Alan

Dragan, you're right. I didn't even remember the G70 having that option, but it does indeed. It's in the "SERVICE SETTING" submenu, and is called "DIRECT POWER". Obviously, this machine is set to "ON".
OK, Alan. Try this for me - because, this isn't adding up. After you've done the "enter enter up down enter" thing and answered yes. Press the menu key and make sure the "s" is there. If it is, then press "MENU" again to exit the menu. Then, before you press anything else, press the "CENT" key and see if get a pattern on the screen. If that works, try pressing the SIZE, LIN, or SKEW buttons.
SC
PS - I'd turn that "direct power" setting off, since I think a power interruption would force a power-on condition when service was restored. Not a good thing, eh?

Mr. Crabb,
The 'S' was there when the menu was displayed. I did as you suggested, and pressed the centering button next after the menu was closed, and a centering pattern was displayed, and I was able to use the Lin, Skew and indeed Reset.
Now I think I have to read the manual some more, before I become smart enough to ask another question.
In the mean time, I will ask a question anyway.
Before I learned this much, and I was just trying to center the pattern of the Red and Blue tubes to the pattern of the Green tube, I could get a fair alignment of the Red to the Green, and the vertical alignment of the Blue to the other two was not bad, but the horizontal aspect of the pattern from the blue tube was "wide right" and I could not move it far enough to the left .
That's why I started trying to work my way through the set-up in the manual.
My question: Does any of this suggest to you that there is a large problem that cannot be resolved with the set-up process ?
Thanks again,
Alan

Alan | Alan the problem is that you haven't read the manual. You don't start by trying to line up the grids to each other electronically. You center each grid on the tube face, turn contrast down and look right into the lens to do this. Then, loosen the screws on top and physically pivot the entire tube for red and blue to line up on green.
The way your doing it can run the grid of the side of the tube face and possibly crack the tube if it get;s hot enough

Alan,
Where in GA are you?
If you are close to me, I would be willing to come by and help you out.
I'm sure there are a few others who could as well.
Let me know,
C.

Good one!

Nope, it means the toe-in (mechanical aim) on the red and blue is set for a larger screen than you're using, and you're trying to move the pattern electronically - which won't work. The projector is probably skewed a few degrees off orthagonal (perpendicular to the screen/wall), and is allowing you to "get there" with red, but not with blue.
Like dragan says, you need to cozy up to the manual for a couple evenings and get familiar with the process before you even start playing with the projector (I know it's hard!). Make a few notes for yourself as you read through. Highlight the important stuff. As a newbie, you have a long road ahead of you to learn to get the most out of that machine. I've been playing with CRT's off and on for years, but only this spring moved to a G70. It's a MUCH more complicated machine than lower-end entry-level air-coupled machines. In capable hands, however - it's an incredible machine. To get to that point requires lots of learning, experimentation, and probably a bunch of help along the way.
So, read the manual. Read Curt's CRT primer. Search and read all the G70 threads you can find. Doing this will help if you run into problems, since if/when you recognize a problem you're having, you'll already know the remedy or will at least know where to look for it. You'll also find tips and tricks. For instance, you'll have trouble if you do your setup based on an external signal. You'll have trouble if you try to fit the internal test patterns exactly to the screen - you have adjust it for a larger area than you'll actually be using - ESPECIALLY if you intend to try 1080p.
Basically, your first setup will go about like this:
1. Mechanical alignment (make sure projector is square to screen and perfectly centered and level)
2. Do a quick optical focus
3. Center rasters and adjust toe-in for your screen size using cross pattern
4. Do super-quick geometry just to enlarge test pattern
5. Bring up dot or EM pattern and do a fine optical focus - center and edges. They interact, so it's iterative.
6. Adjust Scheimpflug focus (also called flapping). This adjust plane of focus in both vertical and horizontal directions. These also interact a little with each other. Iterate to find optimum.
7. You'll also back and forth a little between Schemipflug and optical focus - they're interactive. Nail both.
8. Mark screen center both horiz and vert with tape and string
9. Make sure all convergence and geometry controls zones are set to midpoint - 127/128. If you don't do this crucial step, you will chase your tail for hours. Release blanking completely (0 in all 4 directions)
10. Start working geometry on green. Follow the manual. It's iterative, and the controls work in pairs: size/lin, skew/bow, key/pin. Go back and forth in each pair to nail.
11. At the end, as a last resort, if anything is amiss with geometry, use small amounts of zone to adjust
12. Converge red to green. Same set of iterations.
13. Converge blue to red (or green - whichever you can see best)
Step 1 is a big deal and I've reduced it to nothing here. See Curt's primer about maximizing rasters, but don't go too far on the G70 - you could end up with geometric distortion or focus problems in the corners. I'll have to double-check, but I think my G70 is somewhere around 8-10" closer to the screen than Sony spec.

Mr. Crabb,
Many thanks, and thanks to Dragen, Zebu and CBE for the cooperative spirit. Clearly my knowledge bucket is closer to empty than full. My career has been in controls, without a lot of opportunity to embrace this kind of technology.
My first and only other machine was an old 1040, and there weren't a lot of options for setting the thing up.
As far as 1080P, won't that take a significant modification, or some external hardware ?

Douglas MacArthur said " I shall return"
I'm saying, " I know I ain't done, yet"

Not necessarily. You'll need a source that will output 1080p (HTPC, Blu-ray, etc.), and depending on the source, possibly an HDMI-to-analog RGB interface such as the HD Fury or Moome IFB card.
I'm running 1080p from a PlayStation 3 through the HD Fury, and it's incredible. I sit very close to my screen, so 1080i scan lines are pretty obnoxious. Going from 1080i to 1080p was almost as big of a change as back in the old days, going from 480i to progressive scan. It's amazingly gorgeous. The title sequence from Casino Royale is breathtaking. The subtle background graphics are so sharp - it's really amazing.
To do 1080p, you do really have to nail your setup, though. Mine's still not there. I need to do another setup or two I think before it'll be where I want it. If you search, you can find a G70 thread or two with some of my trials and tribulations learning a new machine. I went from being very knowledgeable on my old Sony 12xx, to being surprised about how much I DIDN'T know when it came to the G70. It's a learning process, that's for sure. There's a lot of general knowledge that's excellent to known and learn and is useful regardless of the projector, but then there's also a bunch of quirks, tricks, and things that are good to know about each brand of machine, and even each model within a brand.
Georgia, eh? Atlanta area? There's some guys around here from there. Where'd you pick up your G70?
Oh, and welcome to the forum!

Mr. Crabb,
Bought it 3rd hand from a guy outside of Asheville, He was a software guy, and ( by his own admission) had no chance of making it work.
He was going to 'give up' buy an LCD projector. It had the issue with the blue not lining up, from the beginning, and I've been concerned that this was a $ 500 mistake. Your comments, along with the others have encouraged me to expect that it is just a $ 500 CHALLENGE.
Best regards,
Alan

I thought the Sony was pretty hard to set-up. Reading the manual goes something like this. Start on page one, read a few sentences that tell you to jump to page 87 which then tells you to do something but if you don't know how to do that then thumb back to page 54, etc. Unless you can memorize the whole thing then you will need to just hold a pen-light between your teeth and try to read the manual while your working on it. Definitely a challenging process even with previous CRT experience.
