La placa lógica del lector de DVD es una parte necesaria para que una Xbox sin modificar o con softmod arranque. En sistemas con hardmod que usan un BIOS personalizado, la verificación del lector puede ser omitida dependiendo del BIOS que tengas, permitiendo que la consola funcione normalmente sin él.

Marcas de lectores de DVD de Xbox

Puedes identificar tu lector de DVD actual sin abrir la consola mirando la bandeja del disco y comparándola con esta imagen.

Generalmente, los lectores aparecen en las Xbox de la siguiente manera:

Marca de DVD-ROM Revisión
Thomson 1.0-1.4
Philips 1.0-1.6b
Samsung Cualquiera
Hitachi 1.6, 1.6b


Reemplazo

Algunos lectores, especialmente los lectores Thomson que venían con las dos primeras versiones de Xbox (1.0 y 1.1), pueden mostrar un error de "disco sucio", lo que requiere que el lector sea reparado o reemplazado. Los lectores de DVD son intercambiables, permitiéndote poner cualquier lector de otra Xbox en la tuya. Los lectores Philips y Hitachi parecen tener la tasa de fallos más baja, pero debido a su antigüedad, todos los lectores tienen tasas de fallo bastante altas en la actualidad, aunque los fabricados más tarde en el ciclo de producción de Xbox podrían durar más debido a tener posiblemente menos desgaste.

Cualquier lector de DVD IDE, aunque no sea específico de Xbox, puede ser usado en el sistema, pero solo podrá leer medios grabados y la Xbox ya no podrá detectar un disco insertado ni expulsarlo desde el dashboard. Una solución para esto es presionar el botón de expulsión, insertar el disco y luego reiniciar la Xbox, momento en el cual cargará el disco.

Un lector Samsung SDG-605B, SD-616F o SD-616T; o un LG GDR-8163B pueden ser flasheados con firmware personalizado para poder leer juegos de Xbox. Las guías están enlazadas on this page.


Reparación

Cleaning/Replacing the Gear Band

If your drive won't open at all, you can manually eject the drive. With the Xbox off, insert a paperclip into the small hole beneath the drive and press it in. The drive will pop open, and you can look into the drive and see a small belt and gears. Remove the belt using tweezers and clean it with a cloth. You can clean the gears using rubbing alcohol and a cotton swab. After it is dry, loop the belt back over the gears and see if it will open and close using the Eject button. If it doesn't, you will need to replace the belt with a new one.

The size of the drive belt varies across drive brands and are as follows:

DVD-ROM Brand Folded Length (mm)
Thomson 55
Philips ?
Samsung ?
Hitachi ?
Cleaning the Laser Lens

If you notice that your drive is spinning the discs, but not reading them, you can clean the lens of the laser either thoroughly by disassembling your DVD drive and swabbing the lens with 91% or higher isopropyl alcohol and a cotton swab, or by using a DVD cleaning disc which has soft bristles that remove dust from the lens.

FPC cables

Some people might have broken FPC cables, these flat mostly white cables connect front PCB with the main pcb, a motor PCB with the mainboard and most commonly, the laser assembly connects with a flat FPC cable. These can rip, break or corrode and if needed, replaced.

for the Thomson for example, the main laser assembly cable has 20 pins, is 0.5mm spaced and is 7cm long. the contacts are on the same side. These details can help replace a cable by ordering them online. Thus, for any of these flat cables, measure the spacing, count the amount of lanes (signals, pins) and length, altho, sometimes getting a slightly longer cable would work if your size isnt sold.

Pot Tweak
Exclamation-triangle-fill.svgThis is a potentially dangerous procedure, as turning the laser up too much can destroy your discs or damage your laser.


If you suspect that the drive is spinning the disc, but not reading them, and you've already tried cleaning the laser lens, you can attempt a potentiometer tweak (or "pot tweak"). This involves opening your DVD drive and turning a screw slightly in order to increase the strength of the laser. This process will not be covered here, as there are many tutorials on how to pot tweak a DVD drive, but you should decrement by 100ohm each try or approximately 1/12th of a turn. It's highly recommended to use a multimeter.

Normal resistance values are as follows:

Drive Brand Minimum Safe Value
Thomson 800 ohm
Philips 500 ohm
Samsung ?
Hitatchi ?

DVD Drive Sub-Models

The drive models are further broken down into sub revisions depending on when they were made.
