First question, is it under warranty? If the answer is yes go to and find an authorized repair center.

If not and you feel comfortable with electronics there are a number of things you can check yourself.
*The following is based off my experience with a KVH A7, proceed at your own risk.
Step 1 take the unit off the vehicle and place it upside down on a flat surface, I use a towel to minimize any scratching.
Step 2 take all the screws out from the bottom. There are quite a few and they are all hex heads.
Step 3 once all screws are out of the bottom carefully flip the unit and separate the top from the bottom. Note the 'Dome' does not remove at this point just the plastic around it.
Step 4 remove the 4 large phillips screws holding the 'Dome' on the satellite and remove the 'Dome'
**Disclaimer** you now have access to the electronics of the satellite, be careful! Take ESD precautions and stay grounded to avoid zapping a board.
Step 5 you will notice two electric motors. One that is attached to a large belt under the 'spinning' part that rotates the satellite and the second smaller motor controls the pitch of the satellite.
Step 6 I would start to inspect all parts and see if anything looks broke or out of place. You should be able to move the satellite around in a circular motion by hand without much resistance (there should be some from the engine). If it does not spin I would check the bottom belt and or the bearing track that the satellite spins on.

I would not advise taking the unit apart any farther. Generally most problems I have seen that are not board related are pretty obvious when you get the top off. The KVH family of satellites seem to be the only piece of electronics in the world that there is no good on-line support or discussions for.

Best of luck!

There really isn't a great solution to this problem. There are 2 likely causes of the grinding sound: 1) Elevation limit switch bad - this can and will happen with any of these that sees heavy use. 2) Elevation motor failure - slightly less likely than the limit switch but it goes too. Just to clarify the grinding sound - it's not actually grinding, it's the LNB slapping the inside if the housing as the controller its self testing during start-up. You can buy replacement parts for these, but it's been my experience that you should take it to a certified repair center or find someone that is VERY savvy with electronics.

    I think elevation motor can't be the reason of this sounds.

By my experience there may be 2 reasons
1- Elevation limit switch, as described in "mysatpro" answer
2- "Unskrewed" screw, holding FAR plate. (see pic)

Hi i have 28 hp mariner and wont go into gear does anyone no what the prob might be cheers

It sounds like something might be loose inside the gear casing or possibly something in the linkage at the bottom. If you are comfortable getting the casing off and having a look, I don't think it'll be too expensive to sort out. It may be a little more expensive if you're not au fait with DIY repairs...

I have a 4o hp outboard marinier and when u give it about half throtal or more it acts like its slipping,

It is most likely a damaged prop. If the gear shift handle is steady while it is slipping, Your prop needs to go to the shop for a re hub. Take a punch and mark the center of the prop (the hub) ,then mark the blade of the prop in alignment. Try it out and see if the marks still line up. If they have moved- the prop is bad.

No image in my screen

When you ask for help, give make and model number. In this case, if display is a CRT type (cathode ray tube, not LCD), then a horizontal single line in the center of the screen indicates a lack of vertical deflection. If it is a vertical line in the center of the screen, it is a lack of horizontal deflection. Both problems can be caused by any number of components, all internal, and requires a technican to repair. Lowrance has a fixed fee system for their factory repairs. See their online info for support:

Solution- Take the cover off the Deckhand 35 by Minn Kota. Inside is a motor drive. Remove the cover plate held in place with 4 screws. inside are nylon gears, most likely broken. The gears can be replaced with a Minn-Kota Deckhand Gear Repair Kit.
I found mine on the web at Northland it's about $24.00 for the kit, plus shipping.
Good Luck!
