Mortal Kombat 2 PCB - No Video, but ROM test screen *ding* is heard
Hey all,
Ok so, I had bought my MK2 board over 6 months ago, had it for a while and then decided to sell it cause I wanted to build myself a Hyperspin/Mame Machine and only keep a few original PCB's (X-men obviously lol). This game *was* 100% perfect with no scratches, etc, working perfectly sounding perfectly.
So the buyer had received it, way overseas, and the video wasn't working. He would hear the first *ding* and that's it, no video, nothing. I decided to purchase it back by refunding and just keeping the game (regretted selling it).
Now I have the game back. I looked all over the PCB and I noticed a couple pins bent (which I've straightened), a couple traces even had a very small scratch that I noticed (which I have to test and repair if needed).
I'm going to straight up blame the customs and whoever IN customs for tampering with the board when it was received overseas. I had included a kick harness meant for this game and the buyer didn't even receive that, so I'm more than sure there was a serious human error in customs..
Anyway, I noticed the same symptoms -- ROM check screen ding, and that's it. No video. However there is one thing - the LED's are both lit up, but one of the LED's (one furthest from the jamma edge) blinks every 2 seconds like it's resetting. I remember both LED's blinking when the game is working.
The sound board LED is lit up. That's about it, oh and I forgot to mention that when I boot the game - if I have the ribbon cable connected from the sound board to the PCB (the power cable is connected) -- you do NOT hear the ROM screen ding. Only when it is disconnected do you hear it
This is the best description I can give - I will make a youtube video showing what I'm describing. If anybody has any idea of what the issue could be (should the trace "damage" not be the problem), please provide input.
So far everything else looks pretty good, so I'm a little stumped
