Tray drive idler gear stripped - Sony (DW-D22A/B2) DVD±RW Dual Layer Burner

Take a pin and insert into a small tiny hole on the DVD tray it's gonna pop out

several possible reasons
build up of worn belt in the teeth of the gears
incorrect belt being used (wrong pitch belt being used -not genuine)
shafts being driven are not free to turn--seizing on the bearings, incorrect placement of rocker shafts /pushrods---valve springs bottoming out locking the shaft
incorrect tensioner actioner ( hydraulic tensioner not tensioning properly allowing the belt to flap in operation)
idler pulley problems ( bearings or misalignment of all pulleys

if it is knocking in reverse gear , that is an indication that a tooth of the reverse gear or reverse gear idler is badly chipped or broken
it will require a box strip down and gear and bearing replacement
best stick with the same gear box as there may be too many difficulties to fit a different box

The switch could be broken. Is it totally silent?
The gear could be stripped. Does it chatter?
The drive gear could be broken. Does it chatter?
The motor could be burned out. Does it whir?

Check the following:


1. DC motor assembly.
Make sure all the motor plate mounting screws are tight.


2. Idler pulley - DC motor assembly.
Make sure the idler pulley is not binding on the pulley shaft. Check the pulley for wear. Check the idler pulley shaft on the motor mounting plate for damage or contamination.


3. Drive pulley.
Check the drive pulley for wear, binds or damage to the pulley or pulley shaft. Make sure the pulley turns freely on the pulley shaft.


4. Motor drive belt - tray drive belt.
Check the DC motor drive belt for damage. Make sure the belt is tracking correctly on the drive pulley, idler pulley, and motor pulley. Check the tray drive belt for damage. Make sure the belt is tracking correctly on

A pulley with gears that drive the long gear along the tray.

from what it sounds like.... its a gear problem. see, inside your dvd drive, there are a set of gears, and a little "rubber band" that opens and closes the dvd drive. either A). a gear has stripped itself(or broken) or b.) that "rubber band" has broke, and has gotten itself stuck(probably in the gears). Good luck, and i hope that it wasn't an important disk.

The gear drive is located in the paper tray lift motor assembly. The gears teeth strip away with wear and tear and can no longer lift the tray to feed paper. Replace this assembly and not just the gear.

this machine is whith finischer?

May very well be a stripped gear in the drive unit. Unplug ice maker and remove mounting screws. Out of the freezer remove front cover and inspect drive gears for damage. Replacement gears should be available through a dealer for you make and model number.
