Instructables
This instructable shows you how to open up your dreamcast and adjust a small potentiometer to adjust the power going to the laser. this is pretty simpe requires no special tools or knowledge of electronic repair, it only requires a careful hand an common seance.

I recently bought a dreamcast off ebay, then a friend gave me a free one...isn't that usually how it works heh. so i went to cleaning the dreamcast and went to test the free dream cast and sure enough it wouldn't read any discs. so i went to looking around and only found a couple of helpfully videos on this subject but no instructables on the issue, so i decided to make one so some one can revive an old dreamcast instead of tossing it out

NOW FEATURED ON HACK A DAY http://hackaday.com/2011/03/07/simple-fixes-breathe-new-life-into-aging-game-consoles/

Step 1: WARNING PROCEED AT YOUR OWN RISK


I just want to make it clear that i am in no way responsible if you some how break your dreamcast or electrocute yourself

Step 2: Tools

this one is pretty simple all you'll need is
a Phillips head screw driver to take apart the dreamcast
a smaller Philips head screw driver (i just ended up using my forceps to twist it)
pliers and or forceps (the forceps also come in handy with keeping the lid sensor triggered.)
a game cd (i used an official game and a burned game cd to make sure both would work) 
and a dreamcast with disc read errors.

Step 3: Take her top off

Now start by turning over your dreamcast and slide off the modem, there is a screw hidden under it remove it and then proceed with taking the 3 others screws one on each corner of the dreamcast. Once you have all 4 screws removed carefully turn the dreamcast back over and slide the top of the shell off.

Thank you very much for a tutorial on how to fix the laser. My Dreamcast is working now, but there is one misinformation in the article.

In order to increase laser power (so it can read the discs better), you need to lower the resistance by adjusting the potentiometer. You do this by turning it clockwise, not counter-clockwise!

Other than that, a perfect guide.

it depends on the machine really with mine i did what the guide said

Oh, sorry. I thought they were made the same and that it was a typo. Maybe PAL systems should be tuned clockwise, and NTSC ones counter-clockwise? Don't know for sure, though.

no, it just depends on the laser some times
