Lowrance down scan question

This question may have been answered before. Just can't find the answer. I have a Lowrance Elite -7 HDI. The down scan is not working. The screen is 95% black with a line of another color at the top. Would the High Definition Transducer be broken? My GPS works and the regular sonar works correctly. Anyone have a suggestion? My thoughts, power shortage or broken transducer??? I added a picture. It looks like a line around 15 feet but i could not see that. I think it is a shadow. Just the red / pink line at the top of graph.
Thank you for your help.

I called Lowrance today. It was suggested that I save my waypoints and then do a hard restart or reset. And was given several options to send my unit in and get a new unit. But it would not include a new transducer. I the new units would be at a reduced cost. Has anyone done this? Lowrance Hook 9 for $275, TI for $325,HDS 7 gen 3 but i think i would need a different transducer. Any help and suggestions would be appreciated. thank you, John

I would try the reset first. Your HDI transducer would work with any of those graphs listed.

Try the factory reset 1st.

If you go with the upgrade keep in mind that it will be a re-manufactured unit, not brand new....

Do the hard reset as instructed. If there's no change, it may be the transducer is the issue so upgrading the head unit only will not solve that problem. The HDI transducer sells for around $100.

I may have an extra elite 7 hdi transducer you can have if you want it. Just pay me the shippingThe bracket broke on mine and I repalced it with a new one and the boat mechanic said to hold on to the old one as he saw you could change out the bracket so I really didnt need a new one. So I believe I still have it in the garage

There's a good man right there.

Wow, that you for the advice. I really enjoy the great people I meet and (talk to ) on TFF. SnowyRiver6. I would take you up on the offer. I will PM you my address and pay for Shipping. ++ cash. I plan on doing the hard restart this weekend but might be tough with Christmas. I didn't know the unit offered would be re-conditioned. So great info there. Again thank you. JOhn

Thank you everyone. I tested the new transducer with great results. Thank you. I owe you money and will be mailing you a check. This Transducer is very valuable. I sent a PM. Thank you Snowyriver6. But I will pay more than postage. thank you. Happy New year.
