Title: GBS-8220 from Gonbes ( cga to rgb convertor ) pink problem
Post by: extreme on January 18, 2009, 06:01:52 AM
We do have 2 sega rally deluxe machine ( 50 inch screens ) wich are bad. I connect a GBS8220 converter board directeley from the sega machine to a RGB input of tree different monitors.
After 2,3 minuts , the screen glows very slow to pink color background
( Not the graphics ) . I tried a 15 inch CRT , a 22 inch CRT and a LG
42inch LCD TV with RGB input. Disconnect the converter or pressing the auto button , reset the pink
screen back to black background. then 2,3 minuts later , it starts all over. Any Idea what is wrong ?
Thx
