Hi guys,
I have some issue with a NESRGB I'm trying to install on an old french NES..
After letting my Nes turned off for a while, if I go back to it, it will have no image and a long buzzing sound. It turns out this buzzing sound is actually the first note of my game intro.
If I let it run, I will have the second note, very slowly , then the third , then some image, then everything will go faster and faster, the image cleaner and cleaner, to a point where the game will actually work PERFECTLY. Image and sound (the all process is probably about 10 minutes)
It's so strange I ve recorded part of the process to show you what I mean.

A few things to note:
- I immediately thought it was a cap issue so I've changed the 3 main ones in the AV box. Haven't changed anything else yet.
- I have a stable 5V on the NESRGB, the PPU and the CPU
- if I put the PPU back to the NES board, everything works perfectly fine.
- I wanted to make sure using the original AV Output and power was not the issue so I'm now using the RGB mini din and the power board.
- once I got any game working it will continue to work . I can rest, power off, change game and all will work. But if I let some time pass with the NES turned off (over an hour) I will get back to no image no sound and the long process described above.
I m very puzzled . As you can see the board can work but I just don't understand why the system will behave like this. Any idea ?
Thanks a lot,
Romi
