This sounds like a thermal issue. Maybe the lcd is overdriven and getting hot. To find out if this is the case, blow cold air on the receiver while it is running. If it stays connected longer than normal under these chilly conditions, then chances are that some component is overheating and shutting off. It will be most likely a transistor on the signal receiving portion of the board. In that case, I am sure that you will need to send it in to Garmin for repair. Good Luck!

What can kill the fire to fuel pump


The fuel pump is controlled by the ECM which receives a signal from the fuel pressure sensor . When the pressure is reached the sensor signals the ECM and the power to the pump is reduced / stopped until the pressure falls . Have a fuel pressure test done on the manifold to check fuel pump--pressure regulator and filter. Run fault codes to check for correct venting around the canister.

Mitsubishi rear projection TV , Model VS-45603.In the last year it started to turn off by itself. It has no real pattern. It can turn off 2-3 times one day and none the next day. It is hooked up with...


What kind of cable are you using to connect it with (coax, HDMI, RCA (composite), component, s-video)?
This may be a grounding problem. Either the cable from the satellite dish is grounded to something with a little electricity running through it or you may have a hot ground in your electrical outlet. Or the cable may be on a different ground than your electrical outlet and by connecting the two it has created a slight electrical current. You can try using a plug adaptor to remove your receiver from the electrical outlet ground. These adaptors are meant for older homes and electrical outlets that do not have a third hole or ground plug. The outer metal part of all video connectors is the ground and this may be causing the tv to act strangely.

I hope this works.

Have Garmin Nuvi 660, after a few min. I lose sats. was working fine for the last year. Just the other day it started. I was in the mountains/ bad weather so I thought that was the problem. I have update...


Try this and see if it fixes your problem...follow these steps.
1. Power off the unit.
2. HOLD down the power button and you will see "Pre Boot Mode" appear on the lower part of the display. KEEP HOLDING the power button down and the display will flicker, do this until the pre boot mode message disappears. This seems to take a long time (60 seconds at least).
3. Once the pre boot mode message disappears release the power button and your device will perform some activites to try recover from the problem.

Receiver not picking up satalites


Sometimes it could take up to 10-30 mins with the GPS turned on and in a clear sky veiw , also not moving -like just laying on the porch or dashboard of a car to re-aquire sats and it datum table.

If that does not work, to fix the antenna would mean prying the unit apart to access the connection on the board.

"no signal" means the unit thinks it is not getting signal from the dish. try reset by holding down the power button on the unit for up to 10 seconds. it will acquire sat and then load guide. this makes the unit "think" again. also check to be sure the cable fitting "stinger" is straight. no signal could also mean the tv or vcr is off channel or is not connected or inputted properly with the original tv remote.

Loss of signal after about 10 minn of time


If it happens around the same suburb the sattelite can't get to that area.

Or it is programmed for another location meaning : it wont display most of the places near you.

Or if its old it wasn't programmed with all the streets as new streets do get built alot.

Also this GPS is a pretty bad one as I am already dealing with 5 others They are all 660s and are the only GPS with problems.

Hope this helps - Josh

No Satelite Signal Indication


The "front end" of your Receiver might be defective. Since your other unit is working then what might be happening is the signal to your unit might be dropping, to check this I would use a Satellite power meter, however if you do not have one you can use your other unit and connect it to the cable that your supposed defective unit is connected to. If the unit works then the problem is the supposed defective unit, if the unit does not work then this denotes a possible cable problem. Tell me if this works for you?
