I'm not sure if this is the right place for this (or if there is a right place). I have a Shark RV1001 robot vacuum that the IR cliff sensors stopped working on one side. The probing I've done looks like there is a short somewhere. On the working side the IR-LEDs get 15V on the + side and 14V on the - side. On the dead side both leads are getting 15V. If I plug the sensors from the dead side into the working side they work. I have a couple questions.
1) Are there any likely components I could/should check for failure, ie: transistors, capacitors, or resistors?
2) Any general tips for reverse engineering/troubleshooting/repairing circuits like these?
Thanks for any help.
