DESCRIPTION: CD tray may not open or close.
REASON: The tray sense switch can grow tiny conductive
"whiskers" across the contact pads shorting the switch and
preventing the tray from opening/closing.
SOLUTION: Change the value of R101 and R102 from 18K to 470 ohm to
increase the current flow across each contact switch pads eliminating the
“WHISKERS”. Resistor 470R 1/8w SMD 0605
