Yes. It's been a consistent problem.

Have u tried out new batteries?

Thanks. It's pretty dramatic. Enough that I have to manually adjust the contrast. There are other problems with this dmg so I'm not that worried about it. It's just annoying. Maybe i'll try replacing some of the caps.

Yeah afaik fluctuation is normal, and due to lsdj entering a power saving mode when inactive.

If the change is so dramatic it's totally unusable you could try changing the capacitors or using a small resistor on the backlight.

..Or I guess you could maybe patch lsdj to not use power saving mode, and rinse your batteries.

Is there any way to even out the power usage in a backlit DMG? I have a problem where the screen contrast changes dramatically when it's playing vs silent. I assume this is power related though I'll admit I haven't gotten out the multimeter.
