Benur75 Posted May 15, 2020 Report Share Posted May 15, 2020 Hello, you can calibrate it. Remoce the drive from the Xbox. Remove the 4 screws. Remove bottom case. Then, unplug ribbon on the righ side on the board. Remove the 3 or 4 screews that maintain board. You can then see the 2 lens pot. With a multimeter, in ohm meter mode, you will read a value between 300 and 2000 ohm. Look at this for the image : https://www.amazon.fr/Link-Lentille-remplacement-génération-compatible/dp/B01EJIW31W The is the pot nearest the lens ribbon. First read the value, write it on your paper, if you read a value of 800 ohm, try 600 ohm (use a very tiny screwdriver, and mode not more than 5 minutes by 5 minutes, if you imaggine a clock, turn clockwise) The last one I had in a broken Xbox had only 600 ohm on dvd, and after a full lens cleaning (Isopropilic alcohool), I put first 800, becasue I though it was dangerous a so low value. Then It did not anything more ! So I put back to 400 ohm, and now it is working well. This is why, you will have first to test with your own original media and with burned media. bye Quote Link to comment Share on other sites More sharing options...

HDShadow Posted May 15, 2020 Report Share Posted May 15, 2020 (edited) Benur75 I've been trying to find a guide for Philips pot tweaking and your description of the technique is clearest I've found. Can you please post a screenshot (use that Amazon one if necessary) and clearly identify the points for reading the resistance value and the particular adjustment screw being referred too. It is the thing in other guides that is not clear. In one YT video the guy mentions the points for taking the readings but does not actually show where they are or the location of the adjustment screw. ------------------------------------ On this matter I have two Philips both /21 and one of those was very picky about media including original Xbox discs. I kept it as a spare. Recently I bought a Xbox specifically for TSOPping which had a properly broken Samsung disc drive. I needed to see if it worked otherwise so rather than swapping in a known good disc drive I used the Philips. The original IDE cable was tatty and badly kinked so I replaced it with an 80 wire one despite it still using an IDE HDD. Much to my surprise the Philips drive started working perfectly. It had originally come from a v1.4 and the new used, now TSOPed, Xbox is also a v1.4 so the only change was that IDE cable. Worth getting an 80 wire IDE cable just to test if it helps with your Philips' drive disc reading. That is if you're not already using one of course.

Benur75 Posted May 15, 2020 Report Share Posted May 15, 2020 Here is a small paper (not from me, but it can help). I will try to do a tutorial this week-end. bye XBOX_philips.pdf 1 Quote Link to comment Share on other sites More sharing options...
HDShadow Posted May 15, 2020 Report Share Posted May 15, 2020 Thanks for that, very useful. So it is the left screw that needs to be adjusted. The equally important thing is the multi-meter reading points that should be used. Quote Link to comment Share on other sites More sharing options...

I disassembled the philips dvd drive, replaced laser lens unit but the problem is the same it does not read anything, to note that the two points on the new lens were not solder. Try with other IDE cable not working. Edited May 16, 2020 by aries Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted May 16, 2020 Report Share Posted May 16, 2020 The 2 solder tabs are meant to be UNsoldered for use they are static protection for handling It sound like the DVD drive board has failed.

SS_Dave Posted May 16, 2020 Report Share Posted May 16, 2020 You will see I have circled some of many via points in black and to me they look suspect compared to the one's in yellow it looks a bit like something is corroding the via point(via point is where the copper is plated through the hole to connect the trace on the other side) I would say the drive is toast Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

KaosEngineer Posted May 16, 2020 Report Share Posted May 16, 2020 Does the laser light up? When you power on the console, view the laser assembly from the side through a smartphone's camera. You should be able to see if the laser turns on and off. WARNING: DO NOT LOOK DIRECTLY INTO THE LASER! Quote Link to comment Share on other sites More sharing options...

Benur75 Posted May 16, 2020 Report Share Posted May 16, 2020 Whatever you repair the drive or not, keep the dvd board as you will be able to use it in a softmoded install, because without dvd board you have an error. You can keep it for a slim xbox project. bye Quote Link to comment Share on other sites More sharing options...

Think of the spots I marked (and that was just some of the spots) as trace corrosion/rott and it's only going to get worse.
