Member: 73159 Status: Offline Thanks Meter: 1 | green light I *THINK* that if the green light comes on but no other signs of life and you've tried all forms of reset, check for one of 3 chips, they are all about 3mmx3mm. and may be covered by screening cans. LTC3411 (marked LTQT) (dc-dc converter) LTC1733 (marked LTLX) (battery charger) SP62000 (marked AIH ) (dc-dc converter) The first 2 are made by linear technology and the last one by Texas Instruments. these are TINY and need a steady hand to change...... it was the sp62000 in a friend's GO that had a tiny hole in it as a result of a faulty charger. If anyone has proper schematics of any of the tomtoms PLEASE could I have a copy? Thanks, Andrew |
