I once fried the ths7374 rgb amplifier while changing the controller and the voltage pin touched the ground shielding. Symptoms were no video blank screen. I’m no expert but could be the chip may need to be replaced.

Thanks @ack. This sounds like a great project that should be preserved for anyone in need to get their broken boards up and running. I haven't used this but can attest to @ack supporting the community as he helped with in the past, getting a neo geo board working by updating the diagnostics rom...

Would like 1 if it’s still available

I need one too.

Thank you

@Mitsurugi-w Is this something you plan to offer?

This is why we buy your kits even though we have a Mister FPGA to play most of this stuff because we want the real hardware as much as possible and less of custom FPGA interpretations. Hopefully, the unpopulated PCB can be made available soon for purchase. Will they be available from the...

This is what I wanted and will make me super happy to have an OPTION to have a an unpopulated pcb that I can populate with a chip that I already have. Thanks for offering this option.

Got my multi today. Super disappointed to see the FPGA version in there. Wish an unpopulated qsound pcb was an option so that I could obtain the chip and populate the pcb myself.

So in for 1. Have waited quite a while for this. Glad it's approaching release.

Finally got around to burning the chips and testing them out. They work perfect. Thanks @ack. I tested it on a a 2 slot that I recently obtained and every test was very easy to get to without having to power cycle the board. Saves so much time and effort. Thanks a lot for your efforts.

That makes sense. Thanks for clarifying that

Thanks @ack for confirming that the binary is built based on the latest source. I was originally confused by the timestamp on the binary files which was june 14th of this year, however, i saw a commit on June 30th at https://github.com/jwestfall69/neogeo-diag-bios/commits/master. But meanwhile...

A small update: Correcting the orientation of the resistor pack has also fixed the calendar error. Now the board as per the diagnostics has 0 errors. Time to clean everything up now. @ack I noticed that you have newer versions of the diagnostic bios at...
