Optical Laser Lens DVD Optical Pickup Replacement Repair Part Laser Lens HOP‑141 for Xbox 360

Everything arrived, the product is as in the photo. Of the three lasers, two are defective, one where the screw screws in has no thread, on the other the mounting point for the screw is cracked, on the third the thread is there but the optical lens is either cracked or has a hair on the inside. Well, the threaded place can be fixed by cutting the thread with the same screw, turning it several times carefully, and glue cannot be avoided here so that the screw holds in the threaded connection. They look new but this is probably a factory defect. For the Xbox 360 fat, 2009 model, I haven't checked the operation, but I'll say right away that the resistance needs to be set yourself because I measured it on one of the 3 pcs., on the DVD the potentiometer is set to 1.65 kOhm but it should be 4.64-5.11-5.66 kOhm. Therefore, when you replace it, it is better to set the required resistance immediately, as the optics are new and if it is less than 3.00 kOhm, it may burn out, and even 3.00 kOhm will probably be too little, the lens and diodes will pass more current, which means the wear resistance will be lower and the service life will be shorter. It is better to set it immediately between 4.50 kOhm and 5.66 kOhm so that they last longer. This info might be useful to someone. And thank you to the seller for sending it on time. In the photo - see the potentiometers, the left one regulates the DVD, the right one the CD, and you still need to remove the antistatic drop. The simplest multimeter will do.
