I have a '17 Helix Floor that was serviced by a line6 repair shop locally (new PSU), that came back with a screen that turns all white seconds after boot. No information is ever shown on the screen.
I can play through it, and all the footswitches work and the buttons and dials around the screen works (as I can see things happening in HXEdit), I can use HXEdit, but nothing happens on the main lcd. It is just white.
What I have done:
1. Connect to HXEdit and backed up.
2. Tried to restart multiple times, tried waiting between restarts, disconnecting mains.
3. Tried all the various reset options (FS 5+6, FS 7+8)
4. Updated to FW3.60.
Screen still all white. Any last resorts?
