Phase 85%
Note that the phase control appears to function differently at the highest scan rate: it"s only apparent effect is to cause a white shadow on the screen. The edge of the shadow left to right is adjustable by changing the phase adjustment. I have the phase adjustment where it is to eliminate this effect.
Thanks

Try toggling the clamp position. 48 code. Generally you want back porch clamp with sync on green and sync tip clamp with 4 or 5 wire RGB.

I thought I'd sharpen the picture a little by going through the setup again , a little slower this time. After a few minutes of adjusting the scheimpflug screws the projector goes to sleep( standby). Is this adjustment really that boring or is there a code that I can use to tell it to stay awake.

It does that to save burning the tubes. I don' t think you can change that, but you could feed it an external test pattern from a DVD, then it won't know it's in test mode, and won't go into standby.

Look people, 123 posts about an Ampro. And some of you larf and larf at Ampro.. Wink

Thanks Curt, Sell me one of those DVD's if you would. A photographer friend of mine explained to me what sheimpflug means to him and it sort of makes sense.
I notice when adjusting the sheimpflug screws that the response to adjustment is subtle compared to the barrels; is this typical or does it suggest a problem? According to the manual the bottom screw balances top to bottom focus and the top left screw balances left to right focus. If left/right focus does not balance with top/bottom focus my temptation is to adjust the top right screw; the manual does not address this and I would prefer to have advice before jumping into something that isn't mentioned in the book.
I ran across an interesting rant on another site that suggested using binoculars for setting up mechanical focus, thought it might be interesting since staring at a pattern for any length of time turns my eyes fuzzy especially the blue and I assume I'm not the only one.
Just a quick rant: how the ..... did they expect anyone to do the setup in the time it takes for the PJ to go to sleep.
And as for the people you say larf and larf at Ampro's I'm sticking my tongue out at them and making a rude noise.
Thanks again.

I don't sell them, but punch up 'AVIA' on eBay.

Curt Posted a video on setting up an Ampro in this thread it's really good albeit a bit mundane at first.

This will be funny after watching it.

The video stops abruptly at 9 min 16 sec and I didn't see anything about focus. The manual appears to be vague on this subject as well:pg s2-3 gives the setting of the upper right lens screw at 1.5 turns, pg s2-6 gives the same setting as 0.75 turns . Neither gives any indication of adjustment of this screw and I have been advised on this site to set the upper right screw at the setting recommended in the manual .
I'm so confused.

It would be helpful to know how the lenses are mounted without removing one to look. In theory the farther from the screen the closer to the CRT that corner of the lens should be to focus so in a ceiling mount the lens should flap in at the bottom and if the PJ is mounted in the centre of the screen side to side should be equal. The lack of an adjustment on the top left confuses the issue. This will also affect keystone and of course this is extensively adjustable in the help menu.
It would be nice to hear from a few more who have made this adjustment.

Forget about using a external source for now. That will be useless without a working undertanding of the terminology and interaction of the different settings. All you need for now is to hook up a source to it and get the projector to show a image then press the "HELP" button. Just follow the instructions for a full set up. If it times out and the picture mutes, just press the standby button and it will come back. The help screens will walk you through every step of a complete setup in a logical order. It won't be perfect the first or eleventh time but will get better each time you do it. Only when you understand how electronic and optical focus is corrected and how to set up the projector will external test patterns be of use.

I was way to ADD to follow the help screen. I just went gung ho at it and got it right. AFTER I read the installers manual.

its great setting one of these up you come out feeling like a different person whose been exposed to radiation especially when you have to do the astig........................

Just thought I'd offer some pictures of the speakers that go with the Ampro

you contrast convergence and brightness are way off please send us some decent pics of the speakers!

Ok sure
I'll try again in the near future. The camera was borrowed from the girl in the picture and we probably should have used the flash. I was trying to get screen shots to go with the pics and flash doesn't help those.
In the meantime I have a question.
The picture is good but could be better I think going from what I read here. I've worked on the focus and I'm wondering : "Using the test patterns in the help, how thick should the lines be?" Setting the sheimflug the manual gives 2 different settings for the screw in the upper right corner : 3/4 turns and 1 + 1/2 turns. It seems that the setting of this screw adjusts the range of adjustment of the other two but the patterns just aren't that sharp regardless. The picture is a lot more clear than the test pattern and I aimed for the centre of the lines using the patterns.
There's probably something else that I should be looking at.

basically the AMpro internal test pattern generator sucks, its useful sometimes, I use it for astig, use the entire guided procedure to set up the pj, make sure it gets to its "resting temperature" thats basically where the temperature stays stable code 39 I think, it usually takes my pj about 25 minutes to warm to this point. If you are not using a HTPC use a external test pattern generator like chip does if you are using a htpc then I use Nokia test patterns after I have set it up to get it as perfect as I can. If your mechanical setup is not 100% there is no way you are going to get a good picture or good geometry, keep your code sheet nearby as well. Once you have set it up enjoy a movie, then when you are rested have a look at your setup and look to improve it. With the ampro remote the great thing is the wire is so long you can go right next to the screen to setup. I hope some of this helps.
