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

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

Dvd driver does not play or burn blank dvds compaq r4000 but it will play dvds & cd its got dvdrw/r rw dvd+r dl n the driver


Try another DVD-RW drive because it sounds like the laser is going bad. Burning requires alot of power from the laser. Playing DVD or playing cd's doesn't require much so thats why it would play those.

Can't use my DVD RW AD-7200S SCSI CdR since it was installed. Can't read any cd or dvd.


Hi,

DVD drives contain two lasers. There's a red laser (650nm or so) for use with DVDs, and an infrared laser (780nm) for use with CDs. If you have lost the ability to access any CD, it's quite possible that the drive's IR laser has burned out.

Three years isn't very long... IR lasers generally last a really long time. But it's certainly possible. Short of some evil software intercepting only CD access (highly unlikely), I would bet on the IR laser being dead.

You can't really fix it, and given that new DVD-R/RW drives run as low as $25, you'd pay many times that in technician hourly charges even if they could. Please post your feedback and Vote if the problem resolved as per your satisfaction.

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.

Xbox does not read my brand new modern warfare 2 or dbz burst limit games it only seems to work on one game gears of war anyone know the problem ?


DVD drive is bad , sounds like the laser .if you have some mechanical skill you can replace the laser in the DVD ROM drive. . if you have access to a multimeter then you can adjust the "pot" on the laser and it will improve but will shorten the lifespan of the laser. If it can last till your new laser arrives in the mail then your great.

The only real way to fix it is to replace the drive or the laser unit , replacing xbox360 drives can be a complex operation if your not experianced . (can brick your drive or turn your 360 in to a fancy dvd player) if you open the case and identify your drive. Most sites that sell replacement parts for these consoles have easy to follow instructions for the product that you buy from them.

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.
