Could be the c-sync thing, but just to let you know, sometimes my screen did the same thing. Finally I got a decent video card, instead of my Matrox cheapie card. Problem went away.
i managed to get it working, however there is one tiny problem left to be solved.
my screen would move down when i perform certain task in windows. say when i try to configurate powerstrip, the screen would go down a lil, when i "apply" a setting in powerstrip, the screen would go down farther than before. is it because i didnt have c-sync enabled? or some otehr problems? btw, my card doesnt support c-sync. and im considering building the csync combiner or the sync on green trick. but im kinda noob in circuit stuff hence its really confusing in building the box, intead of just wiring a resistor
i jsut got all the components neccessary to build a c-sync combiner. i did m-pro's resistor trick and the redness hack. forgot to get a resistor for the brightness hack but after getting rid of the redness, the screen seems bright enough already
anyway, ive got the resistor trick working right now, which is one of the c-sync solution i believe, but it seems like the problem is still there. the screen would move down once in a while. im trying with different timing noiw.
Yeah your timings are probably a little off.
Something I came to find out though, is every card has a little different timing, so if you are trying to use m-pro's, or starfox's or anybody else's, it's going to be different. My timings for my geforce card aren't the same as for my matrox card. Hopefully that helps some too.
ah guess what, it wasnt the timing actually. ive got no idea what was the cause but this is what i did to fix it.
i followed everything in the pic "pic"(the attatched file), except for that i added a wire at #12 at the vga connector and tied it with #13. then I connected it to #5 on the psone header. its basically just like mpro's resistor trick, but without the resistor. after doing that. the screen seem to be fixed and color is pretty good.
another question though,
looking at the psone header wiring part, we can see that the multi-out is on the left and the audio + video-in is on the right. can I cut off the multi-out and video/audio-in part? (look at "pic 2")
You can get rid of that completely if you want to. Look at my how-to and see what I did. I don't have that little input board anymore. http://tidder.rudyatek.com/lcd/
I guess it's just up to you. If you're still wanting to plug into a playstation, you probably want to keep it all together just in case.
oo lala thats an even better wayOriginally Posted by Tidder
how about the 7.5v power header. when u look at the header, there is another one beside it thats suppose to power the psone, i guess i can cut off the pcb of that part as well?
gotta cut off as many useless compinents as possible.
what about grounding the wires? i only grounded it at pin 5. any advantage if i ground it at pin 6,7,8 as well?(the vga header)
