You can try holding in the zoom in/out buttons (+/-) as you push and release the power button.
Hold the zoom keys until you hear a beep.
If your hard restart is successful. You should see the GPS screen with prompts for language etc.
if you cannot get the system to cooperate and all you see is the "Lowrance" screen, then you are experiencing a Castro pic system failure and the unit needs to go back to Lowrance.
It's either a software or processor malfunction. Make Lowrance fix it or make it right by you. 3 in a row all with the same issue means they have a major issue they need to resolve.
Don't take no for an answer. I've seen recurrent problems through the last couple of generations of mid priced 4" & 5" systems.
When my depth finder acted like this I found out it was the sender that had not done well over the winter and was giving me false readings especially when the boat was at speed. The sender and cable only cost around 30 or $40. The hard part was since I have a pontoon boat getting under the Pontoon and replacing the wire in the spring when the water was cold.
My really older, but loved, unit failed and Lowrance pointed out that techonlogy is SERIOUSLY imporved, and convinced me to upgrade to a new unit. I disliked the price, but LOVE THE unit. TONS easier to read, even in bright sunlight, depth sounder portion much improved...twin beams really makes accurate reading, and fast readings (unlike older units).
I have had a similar problem and founf this site where you can get a new card that will work for your GPS. Info, pasted below:
The Nextar GPS-MAP09SDC SD card with updated navigational maps and information has a MSRP of $69.99. Please visitwww.nextar.com to purchase the map upgrades and for more information on upgrading your maps.
Yes, if you download the newest firmware upgrade version 1.2 it will add in other projections and datums, as well as fix other known issues. I would recommend that you run both the 1.1 and 1.2 upgrade for your Sierra, the 1.1 upgrade will fix some issues with the base map.
Both upgrades can be found at the following location: http://www.lowrance.com/en/Endura/More/
Your transducer needs to be adjusted so the return signal can be picked up. Some of these have to be super tuned to receive the signal. Also the transducer may be moving ever so slightly when the boat is traveling at speed. You may have some water turbulence interference all contibute to signal return.
If you have a memory card inserted, remove it...if the problem goes
away, try replacing that card. If the problem occurs with any card then...
Try installing the latest update from http://www.lowrance.com/en/Downloads/Product-Software-Updates/ even if you already had the latest...try installing it again.
If the problem occurs with any card, and after updating or attempting to update, there is a probably a malfunction with the XOG and it will need to be repaired/replaced. The Lowrance contact by phone is 800-324-1356 and go to http://www.lowrance.com/en/Support/Product-Support/Contact/ to email them.
