Confuzzled by Component

[Steve B]

Hey chaps, i got myself a 5" screen that takes component input. Its a bit of a techie-job with soldering and wires and stuff (all credit to Rack!) only problem is, when i hook up my component cable to it, the screen stays white. it switches on and stuff, and the contrast controls work, but when i adjust the brightness nothing happens, just stays white.

Can anyone shed any light on this? i can hook up RGB and Sync to it, although i dont know what the Sync port is for, if it needs to be connected or whatnot.

Cheers,
Steve B

Steve,

I don't know the answer to your question, but I think you must mean Composite - Component is the high end 3 x phono connection you get on the Dell widescreens, amongst others

[5lab]

component on pc monitors is and old connection using 5x bnc connectors - do you mean that?

[Steve B]

the connections are already marked on. its got blue, red, green and sync. its the same as my dell but only my dell doesn't have a sync port, does anybody know what is does?

[Funkstar]

Sounds like you have PC style RGB on there as opposed the AV RGP. I believe the Sync is reguired as it basically needs a regular PC VGA signal fed into it.

[Steve B]

is there any way of wiring up a VGA connection to it instead then? anyone got a VGA pinout diagram for me?

[herulach]

probably not, but its easy enough to convert from pc rgb to av rgb by putting a (iirc) 10k resistor on the sync cable, google homemade vga to scart cable
