I finally sorted out the black and white screen issue. It was either the ceramic capacitor or the resistor connected to the chroma output pin of the MC1377P that was broken, probably when I removed the MC1377P. I changed both and I got color again.

Still have to figure out why the 738 is crashing when it warms up.

check if the ULA get very warm, if so try put some metal to chill it down, also take them out and clean legs gentle on them
I have a bad 738 that have issues with oxi on legs for the ULAs, worked fine after cleanup
