Huh, just found this thread. You guys should let me know when your having these problems. I dont check every thread here.

You didn't get those IFB12A manual images from me, did you? LOL Mine look much clearer.

Anyways, I grabbed the service manual (this is an X2000, right) and it does appear to take a 480P signal. When you select your input B or C, are you then selecting component or YPbPr? you need YPbPr for a HD signal.

Hi macgyver655

Embarassed

you could be right...will fire it up tomorrow night (much past everyones bedtime at the moment.)

As usual I have 6 projects running at once...well least thats my excuse if its just in the wrong card Smile

I did have trouble getting a picture from the beginning as you can see from the start of this thread...however anything is possible.

It is indeed the X2000 and indeed does have IF12A.

I will still buy the VGA to RGBVH cable be nice to have more options...and compare...and if it still dont work

Cheers

Will post back tomorrow.

I was going to say that I think your best option will be a PC or (HTPC) with a decent video card that will scale everything to the native resolution of your projector. Scaling has come a long long long long.... way in the last ten years. Almost any PC will scale better than what is integrated inside the projector. So any time you can send the projector native resolution to it you will get a cleaner picture.

It's a shame you have to use analog for the input though. You would get the best image without a D/A/D conversion, but that was the state of the technology in 2000. Is there any direct digital video input on the projector at all? SDI maybe?

No Other inputs unfortunately...

Just tried once more...but 'no show' using YPbPr input option..on both Imputs A & B Sad

Would watching a DVD thru PC/Laptop VGA --> RGBHV Projector..(at native res ) look noticiably better than DVD Component/interlaced do you think ?
IM going to get a VGA --> RGBHV cable tomorrow and try it anyway...pity I had to do this..as it means I gotta start from scratch with sound.

I guess there is no Add on card for the G70/G90's that would give some kind of Digital input ?

Either that or Im back to that scaler from ebay...at least I could still then use my existing Sound Setup and DVD Player.

have you checked these settings?

How to enable progressive scan component on an IFB12 optional input card:
On the dip switches located on the input plate turn on switch 2 and 3 and
leave all others off. Jumpers 3 and 4 are labeled Sync on one side and
Video on the other. The default is Sync but you want to move these to Video.
Jumper 5 is labeled HD on one side and GS on the other. HD is the default
and you want to move this to GS. Then just install the board and hook up
the cables according to the labels on the rear of the IFB12 (Y, Pr, Pb).
You don't need to adjust anything in the on screen menus. This will allow
your older Sony 125x/127x set to accept 1080i and 720p over component.

Thanks to all for the suggestions.

Got me a HD 15-->RGBHV cable from Jaycar (Im in Australia case)... (glad I didnt watch the cup match with Germany last night though arrghhh !)
Will have a play with the projector tonight..with some of the ideas and will see what results we end up getting.

So in about 3-4 hours should know whats possible with IF12 input card or not (thanks for the options to try macgyver) ..and will compare output results from a laptop at 1024 X 768 thru the new Cable.

Cheers

When you said Jaycar mate i figured you must be in Australia, im in QLD, about 1 hour north of brissy.

Did your cable have "Low smoke, zero halogen" written on the packet too? Wink

Yep same cable light/mid grey.

Ive just tested the cable and laptop ...looks OK..but noise lines on movement/fast scene transitions...Im thinking its probably the laptop..not the greatest graphics card.

Im now just about to test macgyvers IF12 config option...Ive set the jumpers and DIP switches..just giving the projector a quick rest and then will try again the DVD Player with Progressive Scan.

I tried but no go...
Thanks for trying to help though...its appreciated Smile

Looks like a scan converter or a good PC graphics card.

Cheers

Something is just not right. It should be able to easily lock onto a 480p signal. But if your not worried about it then I wont either, lol. Very Happy

Im extremely worried Smile

is there anything else I could try ?

Which bit in the Sony manual (attachment) makes you believe it should work with PSCAN

Playing around ..with PSCAN set ..when you select S-Video on the projector you get two versions of the DVD being played sided by side on the screen but quite sharp (in black and white)
Also when RGB is selected you get a picture but its green.

Everytime you go from S-Video to YPrPb it seems to try and lock on for a sec then fails(check input message)

Its not something I would worry about. I just find it hard to believe the timings are causing it not to lock on. It should still lock but would be shifted. But this display is capable of 1600X1200. 640X480 should be nothing. I'm thinking its a setting either on the IFB card or the projector. To bad you couldn't test that IFB in another device to make sure its not that.

If I have some time later I'm going to check something here and if it provides me with something I'll post it here.

Thanks for your time macgyver Smile

My Default settings (as came with the box) IFB 12 setting is DIP switch1 ON rest OFF

I get the feeling perhaps that the projector is overriding the settings from the IFB12...but thats just a hunch.

If you think the IFB card is bad, I have a pile of them here and could send you one if you pay the shipping.

Hi Craigr

Thankyou for that generous offer Smile

Im going to do a bit more playing around...but Im thinking its not the card...but I cant be sure Shocked

lol

Id gladly pay the postage though..let me go back to another projector I have..same DOM(1999) a Sanyo PLC9000..another old heavywieght and see if it behaves the same way with the same DVD Player and Progessive Scan.

If it works with the Sanyo..then it could be the Sony IF12A input card.

Cheers
