Point the remote control at the camera in your cell phone. Press a button and see if you can see the LED flashing. If it doesn't the remote is history. If it does, then the sensor on the main board of the TV isn't working. You canbget parts here : TV Parts Universal TV Stands DLP Chips ShopJimmy

Here is what it says to do if the hands don't match up with the display time (usually happens after you change the battery).
First, you must locate the buttons on the watch.
The "A" button is at the 2 o'clock position (upper right). The "B" button is at the 10 o'clock position (upper left) The "C" button is at the 8 o'clock position (lower left) The "M" (mode) button is at the 4 o'clock position (lower right), and is the only button you can pull out to set the times, calendar and programming.
To RESET the watch and do the ZERO POSITIONING after changing a battery or having a display error, do the following.
RESET 1. Pull the "M" button out to the setting position. 2. hold down the "A", "B", and "C" buttons simultaneously for 3 seconds, then release them. All digit segments will turn on and display completely.
ZERO POSITIONING 1. Press the "B" button and all the segments in the digital time will reset to zero, with "UTC" showing in the main digital window. 2. Zero the "UTC" minute and hour hand (located in 12 o'clock sub-dial) to the 24 o'clock maker (straight up). Button "A" will move the hands clockwise, and button "C" will move the hands counter clockwise. 3. Press button "B" - "HR" shows in the main digital window. Adjust the main (large) hour hand to the 12 o'clock (midnight) position using "A" and "C" buttons. At the same time, observe the synchronized 24 hour hand (small dial to the left of the main dial), to insure that it also moves to point to "24". 4. Press button "B". "MIN" shows in the display window. Adjust the large minute hand to also point to the 12 using the "A" and "C" buttons. 5. Push the "M" (mode) button back in to its normal position. The watch beeps and at the same time the hands jump slightly. ALL RESET and ZERO POSITIONING are now complete. 6. Reset the time, calendar and other modes.
To set the time. Note that changing the time in any of the cities will automatically update the time for all the cities. 1. Press the "M" button to move the mode hand to (TME) 2. Press either the "A" or "C" button to move to the desired city. 3. Pull the "M" button out to the setting position. 4. Press the "A" button. SECONDS will blink. Set them with "C". 5. Press the "A" button again, and MINUTES will blink. Set them with the "C" button. 6. Press the "A" button again, and HOURS will blink. Set with the "C" button. 7. Press the "A" button again, and 12 or 24 hours tim format will appear. 8. Push in the "M" button to its normal position.
To set the calender 1. push the "M" button to move the mode hand to (CAL) 2. Set the city using the "A" or "C" buttons. 3. Pull out the "M" button to the "setting" position. The numbers of the "month" starts to blink. this is an "american" date system with the month first, day second, and year third. Use "C" button to adjust the month. 4. Push the "A" button. The date (day) will flash. Adjust with the "C" button. 5. Push the "A" button. The YEAR flashes. Adjust with the "C" button. 6. Push the "M" button back in. The calender is simultaneously adjusted for all cities.
Couple of other "tips".
Switching the time on the digital display with the time shown on the hands: 1. Press the "M" button until the mode hand is in (TME) or (CAL) mode. 2. Pressing the "A" and "C" button together. The time will switch the between the main hands (analog) and the digital display.
Temporary Hand Retraction Pressing and holding the "B" button will move the hands out of the way of the display. Repressing the "B" button will put the hands back at the correct time.

This solution is from fixya member ropickym Fixya

solution 1: try pushing the buttons on the tv, manually, and if that doesnt work, call someone to look at it, like a handyman or geeksquad
solution 2: change the batteries in the remote

Try pushing the reset button on the inside of the battery compartment of the remote unit then push the reset button on the back of the main unit (you'll need a paperclip or tooth pick to push the buttons). If that fails I'd start from scratch by removing the batteries from both the remote unit and the main unit then replace the batteries to the remote unit first and push reset, then replace the batteries to the main unit and if necessary push the reset button on the main unit too. Hope this helps.

1. Install fresh batteries
2. Push the SET button for a few seconds until the unit beeps and the year goes to 2000
3 Push the +/- button to get the right year.
4. Push the SET button again. MONTH will blink
5 Push the +/- button to get the right month
6 Using SET and +/-, go through date, hour, minute, 12/24 hour display and weather estimate. The moon phase will automatically indicate for the date you set.
If you put batteries in the remote before you power up the main unit, it SHOULD find the remote according to the channel that you set on the tiny channel switch in the remote's battery comartment.

i believed the problem is the TV mode. (NTSC or PAL mode)

try this
turn mic OFF
press and hold 8 then press power buton (PAL to NTSC)
or
turn mic OFF
press ang hold 9 then press power button (PAL to NTSC)

BertM, I had the same problem and also do not use it frequently enough. The unit finally gave way about 7-8 months. I am hoping that Magellan will honor their warranty and find it's bad battery. I am awaiting an RMA. Visit following site for help:

I had the same problem and finally found my manual. Here's what to do, everyone!

1. Take back panel off the sending unit, where the three batteries are, by unscrewing the 4 phillips head screws (assuming you, like I, had put the screws back in after installing new batteries). You will see a little gray button in a hole above where the batteries are; the little button is one you can push down with the same phillips screwdriver you took the 4 screws out with - don't do this yet.

2. Now, hold down the "channel" button on front of receiver panel for 2 sec, until the dash in the "ch" box and the place where the temp is supposed to be starts blinking.

3. Now, while these indicia are blinking on the panel, push the little gray button down and hold it for 2 seconds. This causes the transmitter to "register" with the receiver. You should now see a 1 in the "ch" box and get a temp reading.

4. Put screws back on, put receiver where you want it, proceed with rest of your life.

I had a LRM-519 that would not get past a very dimly lit "hello" on the LED screen. I called tech support and was advised to make sure no disk was in the unit and turn off the power from the unit (not the remote) and unplug it from the wall outlet. While unplugged, hold down the power button for 30 seconds then plug it back in. This didn't work the first time, but after a few tries it worked for me. My unit hadn't worked for nearly 3 months prior to this. Good luck.

According to LG support, it would have cost $69 for labor plus parts to repair the unit. The main board/power board is $40.

Had same problem. My fix was to repair power supply.
On power supply board replace capictors C18 & C36.
