I have a G07 that won't quite take the v-hold, and it changes some depending on what is being displayed, scrolling one way or another, very slowly. Is this just a bad IC501?
 
Check Resistors R314 and R317
Some came from the factory with the incorrect resistors.

they should be 390Ohm

I will double check the resistors, but the monitor used to work fine.

The header pins are good as I reflowed everything when I capped it.
 
Would like to see suggestions for this as well. Have a G07 with sync mod gets a slow roll (can be tuned out) on Chase HQ and Double Dragon II. others work fine, like Atomic Punk; rock solid on power up.
