NOTES
DESCRI PTION: CD tray may not open or close.
REASON: The tray sense switches can grow tiny conductive " whiskers"
across the contact pads shorting the switches and preventing the tray from
opening/closing.
SOLUTI ON: Change the value of R730 and R731 from 18K to 470 ohm to increase
the current flow across each contact switches' pads eliminating the " WHI SKERS" .
Resistor: 470R 1/8w SMD 0805
