So the green on this Vs. Super Mario I have is off. First I swapped monitors to see if that was the problem, but it didn't solve it.
I measured the green color voltage on the PCB (pin 10 I believe) and it measures a little over 8 volts, which for a Nintendo board means practically no green, correct?
After a few minutes, the voltage will suddenly drop to practically 0, and the screen is just filled with green. All the color pots on both the monitor and board have very little effect at this point.
Got a couple odd readings on some transistors in the green circuit, but I figured it was because I was testing them in circuit.
The roms all check out fine, so where should I start looking next?
