Title: Sync Problem with Lcd's and older consoles pc engine,genesis, snes
Post by: nevarna on May 08, 2010, 07:56:28 PM
I cant get a proper picture with my lcd tv using scart on my pc engine duo.
i get half a screen with a stable picture and the other half is wobbly. is this a sync problem ? i have tried using pin 44 component sync from pc engine graphics chip and ive tried composite sync from the av port to sync the picture but i cant get rgb mode to work stable.
my psx works fine in rgb mode ive even rewired my psx scart cable to work with pc engine but still unstable.

Hi

Did you manage to resolve this issue?

I have the same problem with a converted PC engine Core Grafx console taking the outputs form the EXT Bus connector.

My TV set is a Samsung LCD and the console is connected to the RGB port. (UK based)


Thanks in advance.

Try running it through an LM1881.

Sounds like you're SoL...  Others have had similar problems with UK HDTVs and had to switch to a different model to solve this type of problem... or get a XRGB-3.... :P

Hmm... sounds like a XRGB-3 is your next best option to SCART RGB inputs on your TV.  ;)
