Question about Tomtom GO 300 GPS Receiver
I have accidentally plugged a 12v supply into my tomtom 500 ( which I think is basically the same component wise as the 300 ) and blown it up.
I know through reading posts on this forum that I am not the first idiot to do this. The unit is dead apart from the green light, on inspecting the panel U24 is burnt although U25 and the board print seem ok. My problem is identifying a surface mount component which got completely burnt up.
as you can see from the picture I have removed the component which I believe to be a diode. If anybody knows the value of the component and the number of a possible replacement I would be very grateful. I am led to believe that a 1N414n might be suitable but have been unable to obtain one.
If it is a diode I would also like to know which end the anode is soldered onto, as I say any info on the component would be great.
That diode is a reverse polarity protection diode. An 1N414 will do ( available for very very little from almost ALL electronic component suppliers.) If there is NOTHING ELSE WRONG then the tomtom will still work without this diode. Its not needed in normal operation anyway. All it does is cause the fuse to blow in the cigarette lighter plug if the polarity is accidently reversed. Therefore , with a correct supply , it does nothing !
