The gear and motor assembly on the left tray door is over turning causing the tray door to remain open. This causes the gears to grind and bounce, also. I can not locate a sensor that migt guide this process. Any help is appreciated?

Knocking usually means the gears are not turning the cartridge rollers properly. This would be why it probably doesn't knock with the door open when you run a motor test.
Take the Cartridge out, close the door, and and let the motors turn and see if it knocks still. While you close the door look to see if there is a gear that protrudes from one side as the door closes. If the gear does not come out when the door is closed then it will not turn the cartridge rollers and would cause the knock. Also, if the gear does come out but does not link up to the cartridge fully it can cause the same kind of sound. You would also get a similar result if the gear's teeth are stripped out on the drive side of the gear.
Many models do not have that type of drive gear. They may have a drive gear on the left side of the cartridge compartment. Look at that to see if it show wear and tear.
It's very difficult to change the door on the XBox without causing any damage. I recommend you have it send to someone who professionally knows how to assemble it correctly. I know videogame911.com fixes this sort of problems, they did something similar on my system and cleaned it all out. Give them a try!
Need to open the entire printer, don't feelbad if you are capable you start to open other pl don't open it,its major issue..While printing main motor driving entire printer except fuser assm, entire printer load on Main motor assembly, in main motor assembly contains motor and gears, pl see the marked gear in snap I experienced this gear found warn out, this is suits hplj 5200 main motor gear, you can choose this gear and its easily available.. replace this gear, but opening the printer is difficulty.. thanks..
This is quite common with Hitachi drives ,but I have seen Ben-Q drives with this problem also. Its caused by ether a weak motor unable to break the magnitic seal that captures and holds the C.D. in place . And or grime and build up in the transit gears cause to much friction for the motor to release the magnetic seal and open the tray.
The best way to get a stuck tray open is to press eject wait 1 second and then firmly slap the top of the case over the drive, this will release and open the tray.
The Fix is to open the Rom drive ( Disasembel )and gap the hold down magnet and clean out the gear assembly .
A repair shop should charge 35.00 40.00 for this service But shop around for some one local
If the door will not close or go to home posistion then one or two things has happened, 1. the Unit is out of timing squence and needs to be retimed, this happens when someone pulls on the door while it is opening just one gear tooth out of sequence will cause malfunctioning. 2. The elevator or clamper is not open so the tray can not slide between the spindle motor and the clamper assembly, this usually comes from either a bad or weak belt on the load assembly or worn gear on the elevator or clamper assembly. Open the unit and close the door to check function the disc, should slide between these parts to play, if the door is not closing then you will see why or what is not working or blocking the tray.
Assuming there is nothing stuck in the tray, the gears over time will wear out and the tray will no longer come out. Another possible cause is a weak motor, either way the tray will have to be replaced in order for it to work properly again.
HI, you have two issue here. the load motor is malfunctioning. this is causing the door open and close feature to lock up. this motor is connected to the gear assembly. it should be replaced soon. the second issue is the optical lens assembly. this len assembly has failed. the laser is burned ut. this is causing the no play issue.
In conclusion, i recommendreplacing the optical len assembly and the load motor as well. this will fix this issue. try not to force the door open often, this Will damage the loading dock gears.
I had this problem and it turned out to be the gears on the door drive. There are two gears, one that engages the rack on the tray and one that has a slot that drives the clamping action to hold the DVD. These two gears were misaligned by one tooth. This prevented the gear with the slot from turning freely after the door was closed.
To fix it I had to take out the tray assembly, disasemble it, and reassemble it with the gears properly aligned. You need to remove the top and back of the case. Then take out two screws at the rear of the tray assembly and three screws on the circuit board attached to the tray assembly. Unplug the connections to that board. Slide out the tray assembly. Now you can pop the top off of the tray assembly by pulling out two tabs and sliding the top toward the rear. Now you can get to the gears to adjust them. The slotted gear should be able to turn freely for about 1/4 turn when the tray is closed. Make sure the pin on the clamping part is in the slot when you reassemble it.
