You have something in short circuit in power supply pattern, so filter coils are burnt. It may be voltage regulator, or regulating transistor, electrolytic capacitor or even shorted diode at pwr. input serving to protect in case of inverse polarity applied. Check all for short. Was it reverse polarity or overvoltage occured?

Find a circuit diagram or schematic for my TomTom?

Hi Aaron. Sorry for the delay in responding but I have thousands of photos and not a very good filing system!! Anyway, I have some good quality photos of the boards but, looking at them closely, the resistors DO NOT have values printed on them - unusual I know but they are blank in that area.

You need a schematic if you can get hold of one or, someone with one you could measure from - although this would be difficult.

I have attached some photos, cut down for the area so you can see what I mean
Sorry I could not help more.

Have a 91 chevy instument panel dont work except my turn signals and speedometer.replaced 2 blown bulbs and it still wont light up.steering wheel was replaced.need help

Well check your fuse panel diagram for those components and see if the fuse is there ,maybe they forgot to put them back in or make sure they are good. If so than you might have a headache on your hands if they didnt bother to hook them back up. Or they could have ripped them when they installed the wheel I would have them do it if you have a warranty and if they worked prior to the install. Wiring diagrams can be found inside the back of a Haynes manual that you can get at your auto parts store,it's pretty time consuming and a royal pain. Probably the simplest way would be to pull the instrument panel and just wire it back to the fuse panel off each component(looking at the Haynes manual).Cause by the time you chase down all those wires you could have rewired it.

INTERNAL electronic schematic Powertrain Control Module part number 56044513AC for 1998 JEEP Grand Cherokee with a 4.0 engine.

I understand you are looking for the schematic but it's going to be hard to located.
As your are waiting for the schematic,I recommend you to start checking for damage on the electrolytic capacitors inside the Power-train Control Module.
Here are few sample pictures of what your need to look for. These are not the actual pictures of your TCM.
Look for sign of leaks on the base of these capacitors. The leak will be on the circuit board. mustgo_25.jpg

Also look for top of the capacitor. A failing and failed capacitor will be CONVEX outward. mustgo_27.jpg
Replace these caps with the same micro f rating. The voltage rating can be higher then the exiting cap.

I hope some expert can come though with the schematic but checking all capacitors for damage is a good start.
Please keep me up to date on the repair and upgrade via email.

I need to find a replacement external power input part. Not the end that is attached to the charger but the internal part that accepts the charger. I believe thats at fault because just before it gave up...

if your sure you need the power port..skip all the mumbo jumbo at the beginning of my answer and go to the link at the bottom to locate the part.

the following advice pertains to the following magellan gps systems.

Magellan 800, 860, 2000, 2200t, 2500, 3000, 3050, 3100, 3140, 4000, 4040, 4050 and 6000t

i fix these and many other magellan gps daily so when considering my advice , please understand i do not google my solutions.

assuming your car charger is working (the little green light is on) and your magellan still wont start up after holding the power button while its plugged in for up to ten seconds and still does not below

this is actually a very common problem with these magellan power ports...they are poor quality from the factory and always and i mean always fail..the new ports that you find on ebay are 100% better then the factory port.

if your able to replace that power port yourself, you can get one HERE, if not, ask the fellow that sells them for help.

due to some dubious "experts" on fixya, im not permitted to help you directly, but please follow the link above to get further help.

let me know if you need more help or info

Have you tried talking to Garmin support? You should be able to send this in pay the refurbishment fee and get a replacement. Hint you never opened it or looked inside it doesn't work anymore ....;-]

If something has popped that bad on the board you may run into all osrts of problems to fix. I usually cringe when I get asked to fix things that have let the smoke out. Usually the cause isn't fixed by replacing the burnt out part. That was just an indicator.

Hello All,

I am a utility contractor in Portland Oregon. My trucks all have the 3000T and this is an oh so common problem. I found an electronics store here in Oregon called Frys Electronics. To repair the DC plug you will need to replace it with a new one. It is a 1.3mm dc port/jack and if soldering it you will need to have a min. of a 40 watt soldering iron and need to order a narrow long tiped replacement tip for the iron. You can find all your parts needed at or I can FWD you all the info. Oh the ground strap is reuseable and I have not been able to find a replacement and Megellan sucks at selling their parts. There is also an awsome bunch of guys that have been very helpful @ NORVAC in Tigard OR. I wish you all luck.

Pop the face plate off with your thumb nail right uner the Garmin logo. On the right side you will see a reset button. Depress it for 2 seconds. Replace face plate and power back on.

Weak reception, broken surface mount component

You can not find any schematics for the Magellans.  The schematics are classified.  Even when repairing GPS's for Magellan we didn't receive full schematics.  If your talking about the RF cable connector on the I/O Board (the board attached to the rear housing), then it's an easy solder fix.  For the capacitor/resistor:  I'm not sure where you found the capacitor origin, but if it's black with four legs coming off and parallel with the IC then tell me and I'll msg you back the rest.
