Sony Playstation - Adjusting a Laser \ Optical Pickup for backup CD-R Media.

13:11 Never adjust a laser pot with a bad quality CD-R. Because, if you do that, the laser is gonna to be too powerful for an original disc, creating reading problem. Use always original disc, put the laser on the middle rail and try to obtain a RF signal of 0.95/1.35v p-p. (Tested with my 7002 using an analog scope)

Thanks a million! This is the explanation I needed for repairing my Sega CD Laser!

Subscribed, you taught me something new. thanks

Very instructive video, thank you very much!

I've never seen a PSX with power and eject buttons like that. Very cool.

I enjoyed your video :) Keep it up!

Hi, Just wondered something if you up the laser voltage to read CDR media, what affect does that have when using pressed originals? If you are going to use both pressed originals and burned media is there an in between voltage you would use or just get it to read the worst discs and leave it at that?Regards,Chris.

Very good job 👏🏻!

Good job

Great stuff =D Nice covering the issue about disc wobble - that's something I forgot to mention when following on from RetroGameModz video, but tbh provided you test audio tracks on inner and outer edges of the disc it should be OK. That's also where the tracking and focus gain adjustments usually can come into play (wobble and tracking) - thankfully I've not had to touch those yet. One thing I would say though, it's better to reduce the voltage where possible, rather than increase it. Typically people increase the voltage when CD-R won't work etc, but often the media makes a difference. For example, on my Saturn it won't read the discs you showed there (Maxell etc), but it reads perfectly the Taiyo Yuden discs even after reducing the laser voltage. The other benefit in reducing rather than increasing (if you can, and if it still reads CD-R) is that the laser will last longer. From the systems I've checked so far I've found that at manufacture they set them according to quite a large tolerance. eg. on PS1 I read in the service manualy up to 1.35v is OK, and mine was set to over 1.1v. But it works fine at 1v, and can go as low as 800mV. This is also the reason that some PS1's and other consoles die before others - if the laser was set quite high at factory it won't last as long. I am sure you've seen the same thing with LED's - if you drive them bright, they last half as long. Great video though, lovely scope, lovely video =D

Oooh, I got no oscilloscope. I have no idea how one could adjust potenciometer to get a better result. Got 2 pieces that arrived today, but they simply won't spin the disc any further. Originak and press copy wouldn't work. After trying out different values, it started spinning, but game's won't play. Stuck on PS screen and some struggle to read it.

@Four X Hey can you make a video to adjust the laser for the SCPH 1000 series? They have adjustment dials on the MB

I have a scph-5502. What ohm do i need to set my poti? It only plays burned games normal when in a 45° angle.. Some games start but the FMVs are skipping when in normal position...

if we increase laser power. will it make laser head short life ?

What features do you have to have a digital scope to see the fisheye signal?

@Four X nice video, have you considered showing this process for the PS2?

can you measure the resistance on the adjusting pin?

Hi! I bought a PS1 console. It looks like someone tampered with the rb703 pot. Is that for voltage adjustment? Can I adjust it to the right place using only a multimeter? Thank you.

Is it possible to adjust properly because of induction noise of metal screwdriver?

resistor calibration is between 750 ohm and 800 for cd-r. the cd´s must be clean and been recorded at 2x-4x speed, cd´s carbon positive makes a great copy and green pad label cds are trustable. not use verbatin, sony and other cds when the light passes very free. use cd´s grade A to make copy.
