Recently picked up an AES system I was told was a US version. Asked the seller if he was sure it put out an NTSC signal and he said yes. I hooked it up to my small CRT via composite and I get a B&W picture. Upon examining the system board (revision 1 board), I noticed the CXA1145P chip has pin 7 lifted and grounded to the neighboring clock crystal. From my understanding, this pin should be getting 5V for an NTSC signal. Unfortunately, this is about as much as I understand so far.
From my Google searches, some people have mentioned a PAL jumper, but I think this is something only present on newer board revisions. I can't find any such thing on this one.
So I'm wondering what my options are here. If it's relatively simple, say applying 5V to pin 7, to get an NTSC signal, then I may be comfortable with that. If there's much more to it, such as replacing oscillators, etc., then I'll probably try to find someone to send it to.
Any advice is appreciated.
