HDS 5 Question

I have a HDS5 and I turned the unit on and a message saying "contrast port" flashed on and off repeatedly...I turned the unit on and off 3 or 4 times and finally the message went away and the unit came back on...Did sumthing go out in the unit?...No where in the menues is there a "contrast settings" in the menu... No structure scan and only 1 HDS 5 unit and it is not the HDS5X...Thanks if you can "inform" me...lol...Roger Black

on the power button push it one time with the unit on, then a drop down menu will appear, it has contrast,day/night setting.

I know that part but why would it flash "contrast port" on and off repeatedly?

sorry I miss read the post, and I dont know the answer to your question
