I own a g70 and it is converged right now for 1080i. I run my blu ray and games through my ps3. When I try and play a 720p game the projector is completely out of convergence. Do I copy the memory block of the 1080i converged set up to a different block, then put the game in and start converging? I am lost on how to get different resolutions set up on my projector. Could someone point me in a direction with instructions on how to do this or provide me instructions. I appreciate any help I can get.

Frustrated

I'm pretty sure every different resolution will use a different memory block basically with every input you start all over again.

I'll let the more experienced people confirm or deny this but afaik thats the way it is

The PJ will only load Preset memory #9 for YPbPr signals on input A. If you pull up the menu it will indicate which memory block is used. If you need to handle another resolution you need to use the Video memory or an outboard processor scaler of some sort.

If you are running RGBHV or a DVI/HDMI to RGB card then Preset memories 1-8 will load. If there are mulptiple signals a User block of memory 10-99 will load along with the Preset memory.

Ultimately Yes, you need to converge each unique input.

so how exactly is that done? Do I load the game so that the screen is totally out of convergence and then press menu on the remote control? What are the steps to setting this up? I can't find it in the manual. Please help.

Do you have the manual?

In brief, you first converge the PJ without an input signal. You need to be in service mode. You use the internal oscillator. Starting at oscillator setting P2, then P1, P3, P4, that should cover the most likely frequencies. I would do a simple convergence here.

Then you input a signal from your source. The PJ will automatically load a "Preset" and possibly "User" memory block. You then converge this memory block which is specific to your input signal. Here is where you do the best possible convergence.

so if I understand you correctly. Unplug the hdmi cable from the back of the moome card on the projector. Then turn on the projector, go into serviceman mode and begin convergence. The projector currently is converged for 1080i, how do I make sure I don't mess up that memory block. I appreciate all your help

How do you get to the different oscillator settings? Thanks

Yes, starting with P2

Run your 1080i signal in, hit menu and scroll down until you hit the memory page. Note the two numbers. Input your 720p signal and note the memory numbers. As long as the second numbers are different between 1080i and 720p they write to different memory blocks. If they both use #9 you will need to use Video memory for the second signal.

You need to be in service mode. I believe it is under Settings and should have a pull down list P1-P9 I think:rolleyes:

I really am not trying to sound like or even be a jerk here, but the best thing to do is search the forum here and the other site for any and all info you can find on the topic of g70 memory management issues. It is such a deep convoluted subject there is no way a simple answer in a single post will get you there let alone leave you with a lasting knowledge of how to set it up. There are tons of posts here in the forums, in the archives and over there that will get you up to speed. I personally found that after spending a few hundred hours searching and reading all the posts I could possibly find on G70 memory and just G70 stuff in general answered ALL of my questions. Sorry bro your setup is toast, which is no big deal because I am sure if you are asking these questions, you're not setup properly in the first place. That is NOT a dig, just a very real possibility. It wasn't until my fourth setup of my G70 (my first D50 I set up 4 times too) it wasn't until then that I finally got a pretty firm grip on this crazy great little machine. Do like afryia said and set up to the oscillators first. I personally only setup to P2 and then copy and paste the setup to 0-9 then feed a signal and re converge to that. Start with a good mechanical setup, do the focus, get the astig right (LOADS of fun there) then basic convergence to P2 and so on. It is the ONLY way to set these things up properly.

So short answer, there is no short answer. Start reading everything you can find, it'll take up a bunch of hours but it is so worth it in the end.

Have fun dude you're going to love it when you get it all setup right!

While I agree with most of what you write. What I find on this forum is you can get 10 different answers from 10 different people on ten different threads, so instead of wasting hundreds of hours reading conflicting answers, I post the question. I have already read many posts which start out great and then end up in foreign lands of discussion. What would cause a setup to be toast? Is it toast because I can't currently center the cross hairs when I try and converge the picture with the 720p signal being sent to the projector? Reading the manual of course is a path, but to be able to have interactive discussion with those who have done it provides more info than black and white words written on paper. Especially when you are adding input devices such as Moome into the equation. Again, I appreciate all the help that this forum gives, indeed isn't this why this was set up? To exchange information and help each other. Once I am dialed in with my projector, I will always look to help those who go through the similar frustrations that I am dealing with.

rabies, is right all these topics and more can be found doing a search.

I tend to find more G70 stuff in the CRT Forum archives than the CRT Forum.

That is where you will find excellent treads with professional answers from Terry (Chuchuf), Bruce (Techman707) just to name a few.

ABSOLUTELY!

Yep sorting the wheat from the chaff is always a little work. I think all of us would agree with that. But there is always something to be gleaned from meandering down the paths of wisdom you find here.

What I mean by your setup is toast is not meant to be disparaging although to you from your newbie (not a dig) standpoint it might feel like it is. I am just saying that if you want you projector to actually do what it was designed to do it needs the proper foundation, the proper base starting point to get there. It does not matter if someone had the thing setup for 1080i at their house and you then set it up at yours and moved it around until you got an acceptable picture. I am only guessing there because I think that is your circumstance from your postings.

Yes the sony manual is a DRY read, and then there's Guy's holy focus and Brian's take which at first are a wee bit much to wrap your head around - but only because its technically a foreign language until you are familiar with all of the things they say. There is no cheap AND simple solution to setting up a G70.

There is a simple way: pay one of the setup and calibrator people to come do it for you, but that aint cheap.

Then there is the cheap way: spend the next couple weeks enjoying your current setup whilest you read everything everywhere you can. Then commit to it and do a COMPLETE SETUP FROM SCRATCH.

The first one won't be easy or very much fun actually. If you're like me once you're set up and watching what you think is a very reasonably good picture, you'll realize you're not exactly sure what you did to get it to that point - but you're glad you did. Then you'll start noticing little things that bug you so you'll start reading again and something that was obtuse before will make sense and you'll double check your mechanical setup, reset all numbers to 128, redo the focus the astig and everything else and you'll be like OK I'm starting to get it and then a few months later something else will click and you'll redo it and then it will start making sense to you this new obsession with CRT nirvana you've found.

Or it will piss you off and you'll sell it and go digital

Yep, you opened a BIG can of worms when you lugged that 182 pound 3 eyed monster into your life. Bwahahahahah!!!!!

And oh yeah, Terry and Bruce and Curt and Brian and Guy and AFryia and all the other posters of G70 wisdom, THANKS. If it wasn't for y'all my wife would have shot me - all the time and money I put down the home cinema rabbit hole was for naught but for y'all I would have NEVER figured this thing out by myself in as short a time frame (3 years)HA!

I was following the manual and setting up with the 720p signal coming in to the projector. I was able to converge the green and red perfect, when it came for the blue it was off the screen. Why is that? Can I copy the current set up which is perfect for 1080i and save it under a memory block, send the 720p signal to the projector, open up the saved memory block and converge it to 720? Will that work? If yes, how do you copy the current settings into another block?

Yes you can, only if you have the later firmware. You need to be in the "extended service mode".

Did you calibrate P2, P1,P3, &P4 with no signal first? If not that is possibly why.
