Jap Genny blank screen

Hello!

after all the problems i got with my DPF, it's my jap genny's turn to give up...

When i connect it, i have nothing to screen (but hear sounds 5sec before it loops)

To find the bug, i tested the connection between the ym7101 and the CXA1145...

when i test RED signal, the playing screen (the game in action!) in red, samething with the BLUE and the GREEN....

since these connections are direct connections (no capacitor, etc..) and since there is no cut, i wonder what it is....

since i have game in action, and sound (bug after 5sec) i assume all is ok (even the CXA-1145)...so WHAT BUG?!

if any hint, be free to reply! :)
