1150 white screen only

[Kaimikai]

I just acquired a used 1150l unit… when I power up it only shows a white screen and will beep once after about 20-30 seconds… the only function I can work is the brilliance levels with the power button… no transducer is hooked up yet.. any help would be appreciated… thanks

Likely will need to be evaluated for repair but you could try holding the MENU button on power up (normally until transducer setup comes up).
