Making the RGB signal stronger? - Page 7

That is an excellent build I love it. Well done Fusion-One

Fusion-one. Your build looks great!! After seeing that, I might just have to make myself get 4 or 5 screens. So much stuff to do... so little money

Well, I think I kinda understand what you mean by the NTSC signal, and I made a little diagram (I hope MPro doesn't mind as I kinda borrowed his). I would appreciate it if you could tell me whether or not I am understanding this. Also, how is the quality of your video? Is it comparable to a VGA signal? Here is my rendition of your design... and I can almost guarantee that I have it all wrong

Thanks again!!

That diagram is exactly how I connected mine, and it works great.. I just lopped the end off of my rca cable, and soldered the wires directly.. insted of leaving the fat connector on.

When I was running VGA (in black and white) on the screen, I found it to be slightly clearer.. fonts seemed a little crisper.. but were still too difficult to read. For everything else, though. I noticed no difference between the vga and ntsc.. I dunno how anyone could on such a small screen.. :P

M-Pro-
So do you output a sompletely different signal to your 5" lcd? if so, how?

Fusion:
How do you invert the picture?? Did you somehow turn the whole lcd upside-down inside the case?

Bingo, it was very easy to do. took me less than 5 minutes. no modding at all.. just undo screws, flip screen 180 degrees, screw back in place.

Hi Fusion. I'm using a 5.6" Interact screen, exactly the same as yours. Trying to get it to work using a Ati Rage Fury pro video card, which seems to support that 480i arcade mode. I've used exactly the same wiring as in M Pro's tutorial, and i can't get it to work. Can u explain exactly what u mean by using the ntsc signals on the composite cable ? I'm confused.

U keep that original wiring from the VGA to the LCD, and u connect the Composite on your video card's TV-Out, and on the Sync and Ground on the board ? I'm lost, please help

Thanks in advance.

Cheebster, Fusion is not using the VGA mod. He originally did it so that he could use the AV switch in the back, but found out that he could just use the composite signal and ground from a normal AV cable. There is a picture that I posted 2 or 3 posts above that shows what he did. I also was confused and made the pic so that it could be clarified. Hope it helps.

cheebster · 08-09-2003, 03:28 PM

Alright, thanks for the quick reply. But i'm still hoping to be able to make that interact screen to work with vga input... If anyone managed to get it work, please let me know, thanks !

Has anyone gotten Powerstrip (or something similar) to work on a VIA ITX w/ CLE266 graphics chip?

Hard to drive with the screen down though, I suppose.

You should just build the screen directly in to EACH of your visors.

What's the antennae sticking out over your read view mirror?

Managed to get my Interact screen working, this time with a Matrox G200 Millenium Card. I get a not-so-bright but readable screen, only black and white. I've tried connecting the sync to r,g, and b channels, and i get the same result. Anyone got a clue on what could be the problem ? Thanks in advance.

This is the exact problem I had, and I tried.. oh god did I try to get it to work.. and it didn't. =| I ended up giving up on vga, and went the ntsc route.

Paul, thx.. it was really easy to do.

At first it made it a little difficult to drive, as I was a heavy user of the rear-view.. but ive adjusted to using my side mirrors nicely.. I intend on sticking a large alpha-numeric lcd in the dash, so i can still change music and stuff without having the screen flipped down. The antena is for my remote starter

PS:
If you meant its hard to drive with it down because of having the picture right in my face.. it isnt, when im looking forward, i cannot see the screen at all.. doesnt draw my attention one bit. If i lean back in my seat, though.. I have a perfectly clear view.. very safe! very practical!

TrunksGoku · 08-12-2003, 02:10 AM

could someone post some more details on wiring and connections and some more detailed images on this mod? Its really hard to look at a drawing and try to figure out how to properly wire it via a picture. It would seem more helpful toeveryone is sumone stepped up with some more detailed pics and a step by step guide

I've been beating myself senseless for days trying to understand this mod properly, but its so hard to do without some detailed images of the wiring and connections.

anyone willing to help?

It seems like I'm not the only one who cant seem to get this mod done correctly and maybe if we didnt have to guess about pins and proper connections it would really be a whole lot easier. For one thing is the psone lcd pinouts the same as the thrustmaster one? from mpros pics on his site it seems as though he's upgraded his lcd to a sony psone lcd. Mpro does that lcd still follow the same pins as ur scematic pic? or is it different...starfox said that the 5 and 6 pins on the psone are actually reversed from online resorces of the psone pinouts. It's really hard to do this mod while having to compare the 2 different psone lcd mods on this forum. It's also hard to to decide which one to follow as well and which one has the proper pinouts on the psone, and exacttly which one overs the better image quality???

PLEASE HELP SOMEONE~!!!

Hi. After doing a little research, i've found that the Interact LCD is actually, a TFD50W-32B Toshiba. I've not been able to get the datasheet from toshiba, but i've found a page with some diags from the TFD50W-32B2 screen, which seems similar... it's located at
http://www.hct.zaq.ne.jp/kyotani/pachilcd/boukenoh1.htm . Ok, it's in japanese, but it could be helpfull to someone in here.

I just can't figure out where is the following on the lcd... anyone can help ?

It's not on the board directly in the back of the lcd... maybe i gotta completely dismount the lcd to get access to those components ?

Thanks in advance to anyone who can help.
