Re: IR Sensor Problems — fried?

However, after we shielded 4 sensors with shrink-wrap tubing, mounted them on 2 servos, and tried the sensors using the same code, the servos kept moving and sensors didn't see any IR, even when we stuck the sensor right infront of the sensor. We attempted using both PWM1 & PWM2 on the beacon, also all PWM-DIGI combinations on the servo and sensors.
Did we fry the sensors when we shrink-wrapped the tubing over the sensors, or is it something else? o____O;;
Please Help--!

Could be...
You're sure the sensor leads aren't touching inside that heat shrink?
