SOHW-1633S50C Laser Adjustment

I need to know if anyone can tell me how to adjust the lasers on my DVD +/- RW DL drive? It is a last resort to fix my DVD burner. It won't burn or read anything.

Thanks Jim

Re: SOHW-1633S50C Laser Adjustment

Maybe the flat cable from the lens assembly going to the PCB is at fault, try to replace it.

My LG dvd-rom can not read dvd but read cd. why? is it repairable? I am living near Kolkata, India. Please tell me your repairing shop address.

In my spare time I fix PS-2's they always come in can't read disk's at all or can't read dvd's heres the deal and this is not for the faint a heart. I cannot even tell you the specifics of how to do it but can point in in the right direction. DVD and CD are written at diffrent angles therefore the laser eye gets out of adjustment. Now there is usually an adjustment gear that moves the angle of the lens twards the back of the carrage that carries the laser back and forth. What needs to happen is that the angle needs to be moved very slightly a click or two of the gear.then check it by getting the mechmism to hold a cd and dvd over the lens. On a ps-2 theres a cover that's magnetic that does that however ti is crucial that it all stay together and by the way that is an industrial laser it will blind you if you look at it. Now the thing is if you go the wrong way it will start not reading the cd's so that is how you tell if your doing it right. and as the man said before me the laser can be completely shot (however I doubt that to be the case since it still reads cd's) However all of this is quite the pain in the **** so it better be a pretty good or pretty illreplaseable dvd ( I did it with a couple of SCSI DVD-RW in that case it was worth it the choice is yours.

What BRANDS are compatable w/ HL-DT-ST DVD+-RW GSA-T21N?

I hate to say it but memorex are the worst quality,the reason is that the drive's laser will try to adjust its power upward to burn the disk-optimum power calibration(OPC).Some burner programs display this . I have tried over 8 packets of different memorex media and results are poor ,one in five are coasters .I suspect memorex media will destroy drive lasers as running laser at top power isn't good for its life .I hate to recomend brands but tayo uden,verbatim and sony are good media but not as cheap as memorex but more cost effective!

Dvd problem

not an easy one to fix,

first you'll need to find out if it's the lens adjustment or a laser problem. this will require you to open up the drive, and test it running open, use protective glasses to shield your eyes from the laser.

buying a new one is faster less time consuming and about 20 dollars. Removing it and connecting the new one, anyone can do 4 screws, and to diff cable that only fit one way.

Error: There is no disc in the drive.

This is a common problem I have seen over the years at my lab, it appears that the Laser for the CD, burns out, or the detector for the CD side of things fails..either way it usually results in DVD working 100% BUT the CD side if things is no good... Then ya spen ages going round in circles trying to "Fix" it when there is none, Unfortuanatly it means ya gonna have to get another unit :(
