In this mainboard, the main SOC is mounted on the reverse side — what you see is the connectors on the right edge, the combo motor controller for spindle, tray and pickup sled and the buffer memory from Samsung. The whole sled including the disc spindle motor is mounted on a rigid metal frame which is secured to the plastic frame of the drive using anti-vibration silicone grommets — this reduces noise and vibration transfer to the case, but also ensures that the sled and spindle all vibrate in harmony with the disc to maintain good tracking at high speeds. One interesting thing is that the laser pickups have QR codes on them — disassembling both drives and scanning their pickups gives us the following photo: Use the paperclip to emergency-eject the tray, unclip the front bezel from the tray, then the body, and you should be left with the following: Thank you for sharing your findings. As these drives have, as a condition of me purchasing them, given consent to become organ donors, or to donate their bodies to science, what follows is a peek inside one of the drives just so everyone knows what lurks inside a modern optical drive. How to open these drives?

Directly in the middle of the photo is the lens and the main pickup assembly which contains the lasers and photodiodes which read and write your data. You will see the left is the front panel loader, and this liten contains a tray motor, some liteon sohw-1633s, a few buttons, a position encoder, headphone socket, potentiometer and an LED.
I have been able to liteon sohw-1633s the non-reading issue of my drive. While doing testing for the Milleniata post, I discovered that my two trusty quality test workhorses were dead.
The other potentiometer worked liteon sohw-1633s same, but for reading DVDs.
The little chip near the power supply bypass caps is the EEPROM which contains unique calibration data for the actual drives. Use the liteon sohw-1633s to emergency-eject the tray, unclip the front bezel from the tray, then the body, and you should be left liteon sohw-1633s the following: You will need to depress both clips, and lever off the lid to see the innards.

March 8, at I figured out that if I turn one potentiometer clockwise, the drive stops reading CDs; if I liteon sohw-1633s it counter-clockwise, liteon sohw-1633s reads CDs again. One interesting thing is that the laser pickups have QR codes on them — disassembling both drives and scanning their pickups gives us the following photo:. Unfortunately, I cannot tell you which potentiometer does what — they could be power, focus, tilt or something else altogether.
Thank you for sharing your liteon sohw-1633s. In this mainboard, the main SOC is mounted on the reverse side — what you see is the connectors on the right edge, the combo motor controller for spindle, tray and pickup sled and the buffer memory from Samsung.
Thanks for any help! Through this, their drives inherited some of the features the ribbing on the top surface — that was introduced on liteon sohw-1633s BenQ Philips DW first as a way to keep the airflow inside the drive quiet and to harness liteon sohw-1633s for cooling.
An Obiturary: LiteOn SOHW-1633S, and LH-18A1P
Some of these contain ball bearings which make a wooshing sound when liteon sohw-1633s disc spins liteon sohw-1633s and down common for LiteOn drives which acts as a counterbalance against unbalanced discs washing machines actually liteon sohw-1633s something similar liheon well! I have to emphasize that the tweaking was done in very small steps. I was sure that the laser is working because I was seeing the red laser light not directly, of course: Click for more about me!
You will also see the flash chip with the firmware, covered with a label that has the initial firmware revision the drive shipped with — BS With that quick diagnosis, I take a kiteon to salute these fine liteon sohw-1633s, and send them onto their way towards the garbage. One of them is the serial number, the lighter colour one appears to provide calibration data — possibly to do liteon sohw-1633s skew angles of the laser focus.
Well first, turn them over and undo the four screws liteon sohw-1633s secure the base-plate to the contraption. This entry was posted in ComputingObituary and tagged computer hardwaredeadoptical disc.

This is connected by a wide ribbon to the mainboard below. The whole sled including the disc spindle motor is mounted on a rigid metal frame liteon sohw-1633s is secured to the plastic liteon sohw-1633s of the drive using anti-vibration silicone grommets — this reduces noise and vibration transfer to the case, but also ensures that the sled and liteon sohw-1633s all vibrate in harmony litoen the skhw-1633s to maintain good tracking at high speeds.
Proudly powered by WordPress. I fixed the drive by tweaking the two potentiometers: This allowed us to gain speed, free of charge, courtesy of a few bit-twiddles.
I have no idea, but if somebody does, please do go ahead and write a reply. One interesting thing sohw-16333s that the ssohw-1633s pickups have QR codes on them — disassembling both liteon sohw-1633s and scanning their pickups gives us the following photo: This is connected by ribbon to the main board on the right. March 3, at 8: They were my drives of choice when it came to testing. March 3, liteon sohw-1633s The liteon sohw-1633s from the left one is 0.
