Got a VB it is complete, put batteries on and game in but it wont turn on,,no noises, no vibration, no nothing….any ideas? Heard you guys are the experts so I hope you can help me.

Had a similar issue. Open it up and check the regulator board on the motherboard. Their might be a blown capacitor on it. The voltage regulator is on top of the board, standing up, it’s “painted” black. You can make your own regulator but you’re better off buying a new one and switching boards, if that’s your issue.

Might want to check the contacts on the back of the controller for corrosion, one of my VB’s had that issue.

The VB won’t power on at all if it can’t boot from the cartridge, dust or dirt in your carts or the VB cart slot can also cause this.
