If you think you cant continue or complete a mod, then DONT DO IT!!!! Think about the work you are doing, plan what you want to do and do it slowly, there is no room for rushing!

The bad news is you have screwed the drive. This is the reason I always advise against twiddling factory set pots that have no service adjustment listed in the manuals.
Once you get the tweak wrong its milliseconds to damage the laser and setting the pots back will not make the drive work.
new laser or new drive I am afraid

Buy a replacement drive from someone in the B/S/T. Replacement drives are plug & play... no pot tweaking necessary.

Why do people still do this?  

[TKramka]

Because if you have the right tools, you can get an otherwise "crap" drive to read CDRs and such...

Hehe I knew it would be you.You love your tweaking
fact is its nothing to do with the tools you use or anything else. The measurements are invented by the first tweakers who got lucky and are not laid out in any DVD drive manual by Philips nor is any adjustment data at all  for those pots (I can guarantee that).
Pot tweaking is a botch carried out to cover for another fault on the drive. Yes I know you are going to say it works on every one you have done . The fact is it knackers more than it mends. the ones it mends are short term gain usually.
Use decent media and the read problems are less. Clean the lens on the laser and they reduce more. If you still have problems replace the laser, its easy and cheap.
If you want to tweak an already non reading drive then fine you can't make it worse.
If you tweak one just to try and make it read better or to make it read certain CDRs then you are playing with fire and if you catch a burn ... well thats life.

Well, heres a change of pace, I'll agree with you...  Yes, I do love my tweaking, and yes, I will argue that tools can make or break the box, but I have to say, not every drive I have tweaked came out alive (RIP, Thomson #2 and Philips Laser#1, you have not died in vain).  And you are right, there is no set value to reduce / increase by, and until someone comes up with o-scope insructions like on the PS2, there will be no sure fire way to tell if you have gone too far / not enough.   However, one can set rough guidelines, ex. don't lower below 100ohms of original set value, or don't go below 800ohms on a Thomson.  And, you are right that it damages the laser some, but, in retrospect, how much will its life be reduced...  Yes, it does not fix a laser, far from it, but it does extend its usefull file, and can be used to "coax" stubborn drives to read otherwise unreadable media.  So, what I am trying to get at, is that, yes you are right, it does shorten the life somewhat, and it is not a fix and you CAN kill your drive doing it, but I consider it a great and cheap way to read cheap media (even though I should be using better stuff)...

The repirman was just another guy claiming to be the master but what do you know he does'nt even know that much I know.


I just found these specs

http://forums.maxcon...read.php?t=6936

Are these authentic to any extent , should I try to fix the POT to these values, my current values are about 1K the left one and 2K then right one.
BTW the reason that I fkd the POTS was that I had analod multimeter.( my friend said that OOOO its better than the digital one OOO u should buy it but I was a n00b back then).

NOw i'll buy the Digital multimeter and giv it a shot  (who lnows it  might work a miracle).

I would buy another drive but I am in PK , i'll pay if any one can be kind enough to ship it to PK.

[TKramka]

Those values might not work on your drive, all drives are different, why do you think they put pots on instead of resistors?  There is no set value for pot tweaking, however, if you want to try and fix your drive, try setting it rather high, and working your way down until you find a good working setting.  Who knows, you might have just blown the whole DVD laser diode if you lowered the pots too low...

How can I repair my DVD-rom using the oscilloscpe, some1 mentioned it so plz elaborate it, I know of this technique for the PS2 but I wanna do this for my PRECIOUSSSSSS   XB DVD-rom .

[TheMuffinMan]

They said it hadn't been mapped out on an Xbox drive, so you won't just be able to do it. You're probably screwed on this drive, you're better off paying $25 for a new Thompson drive ( I paid $40 for 2 of them) and replacing it and keeping it stock.


There's a reason all the pot tweak tutorials have warnings plastered all over them, I was able to successfully tweak a Thompson that wasn't reading to almost reading everything, but haven't fiddled with anything else since, like they said above, it's probably your laser that's not working now, you probably killed it by messing with the pot too much, either buy a replacement laser or drive

[TKramka]

If you see a red dot, then there is life left in the DVD part anyways.

1 more thing ppl, the thing that I mentioned abt getting the drive chkd , well I did get it chkd and the guy fkd up the 2nd pot, so now both pots are screwed (i may hav mentioned this eralier).
BTW I found a link abt Philips only on forums.llamma.com , they had a complete guide on its POTs so I contacted the ppl there and I got told that the RIGHT pot is for cd and Left pot is for DVD, i thats so then why does tweaking only the right 1 makes the drive read everythig,

Plz answer abt the above post and this 1 too coz both POTs are screwed, is what I mentioned here abt the POTs authentic or not.

[X_boxed]

Plz Plz Plz tell me the factory POT values (both POTs) of Philips 6011/21 DVD drive manucatured in 2002.

so that i get a hint for getting my drive to work.
