LCD screen is blank

Post by rcfish »

Hello,
On my 9x with the m128 I was setting up a model in er9x and then the screen just went off.
I'm pretty sure that the processor is still workinf fine because I can flash it in eepe. I already tested another screen, but it isn't working.
I have no idea why it isn't working anymore. I don't know if the backight/buzzer are still working because I'm just building a voice model and iI already discounected the backlicht and the buzzer and on the backlight pin I put another switch.
I hope you can help me with my problem.
Thanks for your help

Load your eeprom onto eepe and check the display contrast in radio setup. Set it to about 27, burn it back to the radio, and see if you got something on the screen now..

I mean that the display contrast just went to 0, while I was setting up a model in er9x. Maybe it's somethink that has nothing to do with er9x. I don't know.

I'm not aware of this being a general problem. What I would really need is to know what, exactly, you were changing on the model when the contrast got upset, and if this is repeatable.
