Hi for my 9inch Garmin suddenly having issues with the image. I think it’s a GT54 transducer. Side scan and downscan is fine but on normal sounding it shows clear for 1-2secs and then screen is fuzzy and doesn’t read the bottom. Would this be an issue with the sounder cable possible getting kinked or compressed somewhere?

Sounders only 12mths old however normal use the 9inch for maps and the 7inch (with a 2nd transducer) for sounding so not sure how recent the issue may be….Thanks
