Hi, I have two Virtual Boys. One looks great while the other’s display is too bright. The mid-tones are blown out. For example, on Mario Clash, the title screen Mario and shell guy are almost one color.

I have played with the software brightness, but it doesn’t make the mid-tones darker relative to the bright tones. The same brightness setting looks great on my other VB.

It seems like a hardware issue, is there a known cause for this?

Thanks!

I checked the voltage on the U8 voltage regulator, thinking maybe it was overvolting the LEDs. The voltage on U8 is the same on both VBs – 9v on the left side and 4.8v on the right side.

The blown-out displays work fine when swapped to the other machine, so it is something with the rest of the VB’s hardware.
