I've got a Namco System 246b that when I connect it I hear the first two initial beep tones and then a wah,wah,wah sound that never stops. I've tried to read up and absorb as much information as possible from other post and other forums, but never quite found the answer to the problem.
Somewhere on the interwebs I read over a troubleshooting post that @l_oliveira commented on about the wah,wah,wah sound(” The "wah wah wah" sound os made by the PS2 BIOS when it can't load a bootfile from a dongle”). I deduced that the reason the dongle wouldn’t load was something on the Sony board (mines a GH-006) had gone bad and couldn't communicate with the Namco Board. So I got on Ebay ordered a ps2 GH-006 replacement board and thought eh $20 swap out the part was better than me trying to solder chips. Turns out there's a couple miner (might be major?) differences between the two boards. One specifically is in images below.
The replacement GH-006 board doesn’t have the connection highlighted by the red rectangle in the images. Also the PS2 service manual doesn’t even list the part.
First off is the Namco board even compatible with the replacement PS2 GH-006 board?
What information does that specific connection relay between the two boards?
Finally what steps can I take to isolate the problem because originally I would get the three beeps, but I wouldn’t get and image on the screen?
Any help would be greatly appreciated!
