Pot Tweak for Xbox 360 Lite-on Drive
I had this Liteon DVD Drive that wouldn’t read disks, no matter what. ‘Disc Unreadable’ or ‘Open Tray’ or ‘Dirty disc’ is all that I could see. These errors mean, it could be a bad write or a bad DVD drive. I have made a check list that would take you out of this dilemma.
If it isn’t the DVDs, then you can try a pot tweak. By doing this, you actually give the DVD Drive’s laser a little more juice (I mean power).
Some Theory:
Basically, pot means potentiometer (variable resistance). This resistance is connected parallel to the laser. So, when you decrease the resistance of your potentiometer, you can give the laser a little more current. Therefore, the laser will have more power.
So, from now on, your DVD laser will work a little more harder to read your disks.
What you need:
1) Multimeter
2) Philips #1-1 Precision Screwdriver.
Get this kit, this would be handy for opening the xbox etc.
Procedure:
1) Open up your Xbox 360 (1 quick google search would help)
2) Open up your DVD Drive (Philips screwdriver would do)
3) Now slowly open the 2 parts of the metal shell.
4) When you are done opening, you’ll find this.
(Sorry for the crappy pic, was in a hurry)
5) Set your multimeter to 20k Ω and place the probes on the points mentioned in the pic.
6) You’ll get a reading ranging from 5-6k Ω (Mine was 6.1)
7) Very carefully turn the pot anticlockwise (Clockwise if you have drives other than Lite-on) using your Philips #1-1 Precision Screwdriver.
Again check the reading. You should have decreased around 0.1k Ω.
9) Check if your discs work. (Install it into the hard drive for the best result)
10) If the discs do not work, repeat steps 6 to 9 until your discs work. But DO NOT GO BELOW 3K Ω, If you do you’ll have a good chance of burning up your laser.
Questions? Comments are welcome.
went too low? try reverting the settings..
Nice one it works a treat! I don't have an AVO meter so I went through the pain staking task of trial and error; I turned it very slightly, re-assembled the console(partialy)and tried it first with a dvd then a game until it worked.
I think these idiots on youtube need correcting too, before people end up completely breaking their consoles with weird and wonderful voodoo magic paper cleaning tricks and stuff.
I apologize for the forthcoming lengthy post, but I didn't want to leave anything to ambiguity…
I have the Benq drive and i've done alot of tinkering with the pot, started at 3.7 and rarely reads discs. I only have room for 1 game on the hard drive so that's the ONLY game i can play right now. Sometimes it reads first try and i can get the start i need to play from hard drive and sometimes it takes 30 minutes. I've slowly changed the pot value at increments of .2 (3.7 -> 3.5 -> 3.3, etc) until i reached 2.7 and that's when i gave up. At EVERY VALUE DvD's play perfectly fine, drive doesn't make crazy noises but for 360 games it goes apes**t then. ANY possible fixes would be appreciated. (on a side note, what is the OTHER pot for? music cd's only?)
ok, this sounds a little harsh but, some discs aren't really made for your drive.
Once, I had verbatim discs with different batch numbers. My liteon drive read discs from the 1st batch with perfect ease but it refused to play the other batch no matter what! I still can't figure out the reason.
Also, make sure its not ur DVD causing problems.

music cd – i guess so..
Good Tut @Suhas Glad I read it else I would have been turnig the pots anticlockwise as all the other drives, stay sweet
ive been at this for weeks working on every red ring i can fix them all but every time i fix one it wont read disks so read up on it and tweaks but i still cant get ne of them to work i got six in my room all work but wont read games who want to buy a 360 that wont read games!
Hey my bro decided to try this fix using a youtube video and unscrewed the pot right out. Is it possible to screw them back in or is the dvd drive totally trashed now?
Great tut dude took me all of 15 min of trial and error to get my drive back up and running, thanks!
great work mate,has sovlved the problem with my lite-on drive from elite xbox,which has never been able install games to hardive before.
