Recently bought a used Lowrance x-65 with skimmer transducer and speedo-temp unit. Hooked it up correctly with 3a fuse, plugged it in, and nuttin. Checked power at battery- 12.46V, at power cord connector - 12.46V again. Checked power at power cord to speedo-temp cable .28V. If I press the power button I can see light at the edges of the screen. Sometimes when button is pressed blue verticle lines will appear, sometimes not. Light and lines go out when power button is released. When pushing cord into connector on head unit, it seems to back out,maybe 3/64" or so. checked and cleaned connector pins with crc cleaner. Everything looks good. Cannot seem to get any data to come up on the screen. Souind familiar to anyone?Thanks in advance to any help.....Bill
