Sega MS 2 RCA and Switchless 50/60Hz mod issues

Hi all,

Done a few of these now with no problems, however I finished one last night and after testing it the graphics are glitchy, this only started happening when I installed the PIC chip for the switchless half of the mod.

I removed it and it still does it, its with all games and not just the inbuilt one.

The console starts up and after about 15 seconds of it being on there are purple fuzzy lines over some of the image on the screen and the graphics glitch out a bit.

I have removed everything for now and I am going to start over to make sure all the correct connections have been made etc but have you any other ideas ?

Thanks in advance.

 

Double check the area you worked on and make sure every pin that you lifted is actually connected back to the board, and not just looking like it. Use a very fine tool to try and move the pin.
Also revert the 50/60Hz jumpers to a defined setting. Don't just leave them floating.
