I can't for the life of me get my G07 to sync. I am testing it on my Neo Geo 4 slot. I can hook my WG 4903 to it and get a perfect picture. But the G07 just will not sync. It was working great. It looks like it makes no difference if the sync is hooked up or not. What I have done so far is reflowed the pots and the J1,2, and 3 header. No change. The B+ is dialed into 119.9V. I have done a ton of reading, but not quite sure where to head next on this.
 
On what pins do you have your sync wires connected?

Also, some G07s had incorrect resistors installed in the negative sync section of the board. They should be 390 Ohm resistors. R314, R317, R303, R306

I have my sync is looped on the 3 pin header. H&V Neg. I have not checked those resistors but I will. This started acting up after I changed the voltage regulator. Thx.

OK, just checked these.
R303 - No reading
R306 - 387 ohm
R314 - 192 ohm
R317 - 385 ohm

Replace 303 and 314? And with what wattage?

I did find a few 390 ohm resistors, but I have no clue what watt they are. Any way to check this? orange white brown = 390 ohm with gold bands on the end = 5%
