If you do decide to send the display to Furuno for an estimate you can send it to; Furuno USA Inc. 4400 NW Pacific Rim Blvd.

It is a Furuno 1760 open array with the GaAs FET Front End 4 Tone Daylight display.

I disconnected everything at the head unit, cleaned all the connections, replaced the fuse, and put it back together.

When the breaker for my electronics is flipped on the array begins to spin, the unit goes into its warm up sequence and then after it counts down it goes into Stand By mode.

However at this point nothing else seems to work, I cannot get the unit out of standby and if I press the two buttons to shut it down it just keeps running until I shut off the breaker.

My questions are: 1) Is this unit even worth repairing I am not sure how old it is, but it is discontinued.

I boat on the Great Lakes and radar is a must on the boat, particularly when the fog rolls in.

Does anyone have experiance with this unit and suggestions on trouble shooting 3) I can troubleshoot the array as per the manual, if this is to spec can I use it with an updated head unit.

Some key display parts are no longer available for that unit.

From your description, I believe the problem is most likely the keypad in the display since you cannot put the radar into TX and you cannot turn it off.

Both of these actions require the use of the TXOFF key on the keyboard, but that is just a best guess.

Not that I believe it will help diagnose the problem, but there is a scanner switch in the back of the display unit.

Power the display back up, then see if you can power it back down using the keypad.

I dont believe it will power off, but if I was looking at the unit I would check everything I could.

Is it worth finding out what is wrong with it and if it can be repaired.

The radar is around 20yrs old, but when working is still a good radar even by todays standards.

If it can be repaired, you would still have a 20yr old radar, so you need to consider that.

I would not spend more than around 100 to find out and no more than 400 to fix it.

In my opinion, it is worth having a dealer look at it, or you can send it to Furuno USA for an estimate.

I do like old equipment so my opinion on fixing your radar, if it is even possible, may not be sound advice.

Your other question, can it be connected to a new display, possibly color, not easily, not reliably, and not affordably.

If you are looking for another display to replace your own then I would look for another 1760 display.

Other displays in that series are similar, but power supplies and SPU boards have different components and or jumper settings.

Whatever choice you make you should still consider it a temporary solution.
