Hello, I've had a miss-hap with my Touch, my fault entirely. I accidentally plugged my Laptop charger into it (19.5V @ 4A!) instead of the usual 5V, polarity was the same.
I've damaged it, it no longer turns on naturally and I really really really want to get it going again. I've opened it up and started fault finding . I can see 3 of what I presume are rail voltage regulators that fed directly from the 5V in from the external PSU, hence the assumption. 'U28' which I believe is 3VTOH is physically damaged, either side of it are 'U26' and 'U27' which are OB26 and 3VE08 respectively and also possibly damaged but U28 for sure has taken a direct hit and sunk! Has anybody else here had any success in repairing a Touch that has received an over-voltage state? Any schematic info or test point readings? Thanks in advance, Dave. ------------------------------------------------------------------------ Dave the bass's Profile: http://forums.slimdevices.com/member.php?userid=53897 View this thread: http://forums.slimdevices.com/showthread.php?t=99515 _______________________________________________ diy mailing list diy@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/diy
