Hi,


I have been reading the forum for a while and decided to import a sharp 10k into the UK.


I have wired up my DVD via component video, no problems but my sky satellite box has a scart with RGB and composite outputs. I have tried taking the RGB signals (live/earth) to three RCA connectors but the PJ will not show a picture. Someone said I nead a sync signal also. My question is how can I get the syc signal onto the green feed. I don't want to use 4 cables. Is there a method for wiring the 3 cable RGB into the scart that provides sync for the PJ.

Roger,


The advice you got on sync is right - per Video Demystified, the RGB signals in SCART carry no sync. The composite video signal carries the sync for RGB. So you need to separate the sync and video of the composite signal (I believe National Semiconductor makes the LM1881 to do this) and then sum the sync only back into G. This is obviously not a trivial undertaking if you have to design a circuit from scratch. Since SCART is common in Europe, maybe somebody there makes a box to do this. I'm not that familiar with the 10K. Does it have separate sync inputs or only sync on G?

Thanks for your help which does confirm my thoughts, the projector does have a composite sync connection but i have plenty of 3 wire cable which i wanted to use.


I will see if i can find a box somewhere.


Thanks again


Roger
