Hi!

I tweaked my phillips dvd drive, and I think I failed. Because before tweaking it read all the normal dvds. I tweaked it because it did'nt read cd-r etc. Now, my drive don't read any Dvds at all. But it still reads Audio cd, and cd-rw. So is my drive really broken? Or can that operation broke the laser so, that it only reads audio and cd-rw. I thought that when it has crashed it has crashed well.   Propably you know what I mean.

Thanks!

Yes tweaking the pot can destroy the drive. The pots on the early Philips are one for CD/RW one for DVD/RW.
This is why I say do not tweak drive pots in all my posts on this. Loads will disagree but any how you now need to buy and fit a new laser from ebay or where ever. they are very cheap and easy to fit.

Depends which laser is in your Phillips, if it is the earlier model you are looking at £9.99+p&p. For the later model it is £20.99+p&p not cheap at all in my opinion

Its a lot cheaper than a new box. depends how tight you are with your cash. At the top price for the newer drive and £25 its still cheap. Did you ever look at the price of Fags and Booze these days.
Of course the cost at all is avoidable by not tweaking

Ok, Thanks!

But if I buy that new lens, then I can still read only the Dvd's, like before the tweak. So maybe I should buy a samsung drive, because it's important that the drive can read cd-r and dvd+/-r.

Just for make sure again: If my lens reads audio and cd-rw, but not DVD, it means that the whole drive is broken totally?

[Chancer]

Yes if you are not careful with the tweak the laser is history. Will not even work if you put the p[ot back to its first position. If you were tweaking to read CDR then you tweaked the wrong pot as well.
If you can get an early smasung they usually read CDR but not the new ones. Samsung will not read DVD+R unless your burner supports changing the book type to DVD Rom.
 The new Philips drives read CDR no problems.

Yes, have you tried returning the pot to its original position? I had a similar problem with my Phillips, slightly over tweaked, CD-r would run fine but all dvds became slow and noisy. By slightly rotating the pot back the other way a bit resolved this problem loads. There is a fine line mind to get the best cd/dvd compromise, I tried one to many times to perfect it and managed to shear the pot clean off hense the knowledge on replacement lense prices.

Try not to take this the wrong way Chancer but £25.99 is NOT cheap for a laser. You can buy complete drives for a little more or a whole new second hand system for just over double. Plus there is the risk involved when fitting the damn thing.

The drives you can buy for £29.99 +shipping are the Thomson ones though. You should see the trade prices we have to pay for some lasers and you would see why I reckon its cheap. EG Philips DVDR610 Laser assy, trade via Philips dealer account £276.94 + VAT. New machine £149.99. It doesn't make sense really.
average prices for home DVD lasers that we repair are around £40. You can probably see where I am coming from now. I fitted a Laser to one of my PS2 it was 34.99 + shipping but still worth it even though the machine is only £99 new. Its being drummed into us all to throw away electronic stuff instaed of refurb

You probably burnt out the DVD laser.  What model drive do you have, the VAD6011 or the 6035?  The laser on the 6035 is a little more delicate when it comes to pot tweaking then the one on the 6011.  When I tweak, I try and take it slow and only go about 50 ohms at a time, and take a max of 125 ohms off on rare occasion for the 6011 drives, and 100 for the 6035, and even thats pushing your luck.

Ok, my version is 6011. Is it the earlier model? Anyway, the reason why I screwed this tweak, was that I tweaked the wrong pot . So I tweaked the pot little by little and tried if it works with cd-r... and it didn't work, so I tweaked it more... then when I had turned it much, I tried with a normal Dvd, and it didn't work anymore... so at that time I thought that you must tweak the same pot, whether you want that it reads cd-r or dvd-r, and it was clear to me that you can check if it works with a normal audio cd, and of course it worked all the time.

So I screwed up, and now I tweaked the other pot... and guess what! Now I can play those cd-r's what I wanted at the first place... but unfortunately not dvd's anymore...

But what can you do? Bad luck, bad luck...

Btw, the reason why it doesn't play dvd's is that the first pot is broke? or that the laser is broke? I don't understand that how can the laser could be broke, when it nicely plays cd-r's...?
