Hi folks,
I am doing a 2nd consolised MV1C for a friend. I have checked the voltage after soldering, everything looks good. Followings are the connexions:
Ground: 1, 2, 27, 28, A, B, E
+5V: 3, 4, C, D
Green: N
Sync: P
Red: 12
Blue: 13
Sound: jamma nation stereo mod.
As a result, I have no image and no sound...
Note that:
- I used jamma nation tutorial and double (triple) checked (with a multimeter)... without finding the issue.
- video signals (except sync) are connected straight to a RGB to VGA connector.
- I have tested it with a MVS cart (which is working, tested on my other CMVS), and without.
- Before soldering the wires on the MOBO, I have tested it on my other CMVS installation, using a jamma adapter: it was working as well.
I don't want to unsolder my wires to test it back on my other installation, due to lack of time.
Does anyone have any clue to help me?
Thanks
