I just got a MV1B board from a seller on Ebay, and the graphics and sound are all messed up. The sound at first was only coming out of one speaker, and then no sound at all. The graphics are all scrambled and blocky.
My video and power equipment is probably not the problem. Here is the following of what I am currently using in my setup -
Behar Bros. Shogun Ultra Supergun (brand new, just got it last week)
Suzo Happ 15 AMP Switching Power Supply Arcade Multicade (https://www.ebay.com/itm/264977336417) - All wired correctly for 5 volts
KabelDirekt – 6 feet SCART Cable (21-Pin, Multiple Shieldings, Precision Connector, Full HD) – Pro Series - https://www.amazon.com/dp/B01DYELZXE?psc=1&ref=ppx_yo2ov_dt_b_product_details (also a brand new cable)
MVS Terra Onion Flash Cart - https://terraonion.com/en/producto/neosd-mvs/
Gscart auto scart switcher
I have cleaned all the pins on the JAMMA edge, cleaned the contacts on the MVS flash cart, made sure both ends of the scart cable are firmly plugged in on both male ends, made sure the JAMMA edge is firmly inserted into the supergun, and made sure the MVS flash cart is inserted properly as well. I turned on all of my 19 other consoles one at a time to rule out that it isn't a wiring issue or because of my gscarts not working, but every single one of my consoles do not have any graphical or sound issues like this MVS board. The MVS flash cart settings was also tested to make sure it is working for the MVS, not AES.
I also made sure to set the voltage at the lowest level on my arcade power supply, and gradually turn it up to read 5 volts on the meter on the supergun. I didn’t fry out the supergun or the board.
These graphic and sound problems happens for every game, not just a few. My conclusion is that there is a chip issue or a trace issue.
I included a couple photos on this post. I wish I could add videos, but this forum isn’t letting me for some reason. If anyone can help please let me know! Thanks
