Hi, looking for some advice. I recently got a PPI pcb boardset fully working but still have a few issues. As you will see in the photos, the left and right sides of the track are garbled and the entire left side of the track is red and white stripes rather than grass. Lastly, there are boxes around some of the alphanumeric fields. Any suggestions would be appreciated. Thanks!
 
Can't see pics but my first instinct is to carefully remove and re-insert game ROMs, checking the legs for corrosion or damage.

Voltages good? PP is one of the most infamous nonworking games ever. We should perhaps all be praying for you. :D

Thanks, Jawhn, I just uploaded the photos. Yes, already took all proms out and cleaned/replaced. Voltages are good as well.

what about the customs?

the manual has a list of failure symptoms and their accompanying chips.
