Working going into storage but when pulled found corrupt video in the form of two stripes from top to bottom (w/monitor oriented vertically) about 1" wide and no audio. Test pattern distinctly show missing areas corresponding to mentioned stripes. Any assistance with this is greatly appriciated. |
| Falken Hawke:
Finally able to start looking around and found a couple of open capacitors. Of course, being a weekend, the only source of passives is closed so dead in the water 'til Monday... I guess I'll start collecting datasheets for now. Can't reallly continue with open circuits. |

Wow, that IS really funky. Wish I could be of use but I am NOT that smart yet. Somebody here should know what is causing it though. And that is a test pattern generated by the board?! Never seen anything like it. |
| Falken Hawke:
Hey Bobby! This board has a test mode which has two screen test patterns, similar to the Neo Geo MVS ;D Figured out RAM Error address: 09 C0 10 0 I just cycled the Object Output Tests and compared their ID's with the error. Unfortunately, also found no objects display in test which is interesting because play is largely unaffected. |

Anyone familiar with Yamaha YM2203C and/or YM3014B? |
