|
|
Hello everyone
Well, now I have a RUNCO IDP990A => NEC 6PG+. Therefore American model 110V, I modify the power supply (cut JP02 and JP03) for 220V (I am French).
And I have a problem with geometry on my image.
- Horizontal lines are not right (left line goes down and right line going upwards).
-The setting TILT / PHASE has no influence and is not as described in the manual (see here).
So I would like to know from where the problem may lie?
I think the horizontal amplitude is poorly adjusted(too large)
In anticipation of an answer thank you

The 990 is a 10PG I believe, not a 6 PG+.
I'm guessing that you might have a bad system board or deflection board? I can test/repair them for you.

CAREFUL:
this info is for the 6/9 PG Plus.
Runco's version of the 6PG Plus was the IDP-900A
So, if your projector is in fact an IDP-990A then the following info is not applicable to your PJ (you would need the PG6000/9000 settings then).
I have never heard of a 990A btw
Make sure the scan reversal plugs are set properly, and also make sure that projection type in the menu matches your installation (i.e. either Ceiling Front or Floor Front).
See attachment for scan reversal plug instructions.

Btw, the images you linked to look just fine.
You may simply have to rotate the deflection yokes a bit.

Was this running ok before or what?
Phase isnt out but it needs to be converged. Are you sure you have a signal entry done for the signal or did it say unregistered signal? If you cant store then its not entered. Might be time to read manuals and learn what the functions do to converge. Manuals are on this site as well as some photos in the PG section. The service passcode is 2580 for this model. Doug
Pretty sure its a 900A (Plus) . There was no 990A that I know of just the 990 that is a 10PG

Thanks for the answers
It is a IDP900A sorry for the error.

Thank you, but that's a little far france; canada.

I am sure for scan reversal plug and the set-up.

For the deflection yokes I know, but I do this for an image relatively straight runs.
| dbaisey wrote: | | Was this running ok before or what? |
no I buy the unit and make the modification on the power supply and try to adjust
Ok I post a new photo with comments see here.
What do you think? (It is not easy to take the default)
thank you

That is keystone balance if the cross hair is level and plumb. If not use tilt. Look in the manuals but you hold the ctl button down then hit keystone to be in keystone balance then use up and down arrows when the green color is being used. You will need to look at the pictures in the manuals so you can see what they do to the test patterns. Doug

I do not think, because I have the same defect on the CROSS-HAIR
see you

I guess I'm missing something. Can you put up just the green. Doug
Looking at it again it may need a click or two of tilt phase. Left and right arrows if you have a signal entered for it.
To shut off the red and blue hit the R and B button.
You might try to even up linearity left to right and top to bottom

Just for the heck of it and if Runco still has it in the menus try degaussing it twice. The later models had center and edge line distortion for corrections so you will need to work with what you have. It could also be how the screen hangs if it has a wave in it. When fine tuning tilt phase turn up brightness to see the back raster then watch the outside corners for curve swings. Linearity will need to be done first then go back and check. Doug

Hello,
So here's a photo of the green cross-coarse with a string to see the default
And another of the green cross-hair
have a good day
see you

Do you have the signal registered for this signal? Does it allow you to store?
Can you do the corrections mentioned above starting with phase then see what you have. They will all have some affect.
The linearity on the left side is bigger then the right side, look at the outside box size as well as the top to bottom.
The way it is now you would use tilt to match the line then a bit of bow followed by keystone balance but this is using the internal test pattern, you would want to use external test patterns for more accuracy but that is part of learning it. Have you sized the actual image to the screen yet?
If you make the corrections I think you will find you don't have a problem. It may or may not be exactly perfect but I wouldn't suggest using point to try make make it that way. Learn all the geometry corrections the right way. Doug
Phase is shown (with picture) on page 58 of the install manual if you use the link above.

OK, I will repeat all the settings from zero on a new entry, using external test pattern (philips testpatterns).
What is the best resolution for that?
800 * 600; 1024 * 768; 1280 * 768; 1280 * 1024

On page 58 of the manual, the first drawing (upper right) shows the dotted lines. Is what I must see (as the dotted lines) on my screen?
see you

This all depends on what you will be using the projector for. If 16:9 screen you would want to use a 16:9 format resolution or what ever the source will be putting out for that. If DVD playback you can use the Avia test disc for widescreen 16:9.
The others can help you with that but the projector will look good using 1080I or 720P.
The dotted line is uncorrected and it will be tilted but disregard the tilt and make the lines running across as straight as possible then raise the brightness and take a look at the corners. Store when done. Doug
You can use the internal patterns to practice and see what things do

Hello,
Some new, from France.
Then, I managed to get a nearly perfect rectangle. There is just a slight wave at the bottom of my screen (but it is acceptable).
But, I think my DEF BOARD needs a good check(just to be sure because I don't now the historic of the PJ), which knows somebody who is capable of doing that?
A big thank you to all, especially to Doug
see you
