I need some help with my Hyper 64!

[Tom_Weise]

Alright, I bought a Rev. 2 and a supergun. I hooked everything up and started the supergun. I can hear sound from the speakers, but the video is just a bunch of colors scrolling across the screen. I have it set to MVS wiring. The supergun has an RGB to NTSC converter. Why won't my TV display the video correctly? Also, I have no other boards to test, so I don't know where the problem is originating from.

Try posting this in the Tech Support forum. Some people in there know a ridiculous amount.

There are a few things you can do.

1. Buy an inexpensive voltage guage. It is never a waste of time to double check the +5v and the +12V lines. Also make sure you do not have the -5V line running current.

2. Re-seat the game to the motherboard and fasten it with the latches. Ensure that that ears on the game are not bent and the game is flush with the motherboard.

Can you tell us what type of TV you are using? Is it a CRT or HDTV? Some HDTVs try to upscan the signal from the convertor.
