How do i keep the power on when it goes out in five seconds?


You can't. It's the systems' internal safety circuit shutting it down friend

Not an expert on those machines but it sounds like the power output stage is faulty and overheating causing a shutdown.
Needs new output stage or repair ?

Will not turn on


Hi Larry -

Your Nuvi 765T should light up when you connect it to your computer's USB port. If it doesn't, there may be a problem with the USB port. Try connecting to the other USB ports on the computer (or a different computer - such as one at work, etc.) if needed. This will help rule out a defective USB port on the computer. You can also connect to a USB charger for another device that you may have instead. It may not charge with another product's USB charger if it provides a very low power output though. The auto plug will not charge the Nuvi when it gets into this condition. Even if it does not light up, leave it plugged into the USB charger / or port over night.

Check the GTM20 traffic receiver plug. It has two LEDs on the body. The one closest to the power cord end is the Traffic Reception Status light and the the one closest to the plug end is the Power light. If either of these lights is on when connected to the Nuvi, the fuse is good. If not not, you may need to change out the fuse in the FM traffic receiver plug. The plug powers both the traffic reciever and Nuvi. Carefully spin off the bright metal ring to disassemble the end to access the fuse. Replace if it is open / blown. If you need replacement parts, they can be purchased from Amazon for about $6.

After charging over night via charger or USB port, disconnect the nuvi from the power / USB cord and turn on by sliding AND holding the power switch in place to turn it on. Keep it held in position for 10 - 15 seconds before letting it slide back. During this time, the Nuvi should start up.

If it will not power up, the battery may be unable to accept a charge. You can replace the battery yourself, but it requires a steady hand, jewelers tools, good eye sight and patience from people selling parts to do this on eBay for as little as $6. Here's a link to those auctions.

If you'd prefer not to do the work yourself, a second option would be to let Garmin handle the "repair". Your 765T is likely out of warranty, and garmin offers a "flat rate repair" fee of $99. If you opt to do this, you will send your 765T to garmin and they will send you a different 765T that has been factory refurbished; complete with the most recent maps available already installed and a gaurantee good for 90 days. Not a bad deal when you consider the cost of upgrading just the maps one time on the 765T. You can start the process on garmin's site, linked here. I have used this service myself and was quite happy with it.

I hope this helps & good luck!

I have a Jvc Rx-6040b Receiver this morning i tuned it on i got no display 3or 4 seconds later it shuts off so i unplug it for awhile.Then later today i tried it again and the same thing happened.. anyone...


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

I have a JVC RX618V stereo receiver which is about 20 years old that suddenly is not outputting a stereo signal. Any idea what the problem could be?


Please clarify. No "stereo" output or no output, period?

What source(s). Try FM.

Is Tape Monitor On? Turn it Off.

Speakers On or Off?
