Hi power is good. When you turn on you can barely see logo when it loads and you can't see sonar at all. Yes I hit power button many times and still nothing. I do believe it's an internal problem bit I'm looking for what others have seen. Also does anyone know what Lawrance charges to fix a unit. I bought my boat used and the unit is a 2019 so it's out of warranty. Seem crappy that a 3 year old unit that cost over $3k would break already.
