Re: Roland D-110 dim backlight

This to jxalex My D-110 display is dim but has decent contrast... I measured the voltage out of R5 and got 3.8v, R5 tests at 9.5 ohms, looks like it should be 8.2, I jumped it with a diode and got a bit under 4.5V, much better. Question, can the LED display handle the full 5V without breaking down? ...
