Calibrating PS1 laser. HELP

Postby portnoi88 » Sun Jul 15, 2018 6:38 pm

Hello,
What is the best way to calibrate the PS1 laser?
Should i disconect the flat cable?
Because i get different readings. 850ohms conected and 1300ohms disconected.

Disconnect the ribbon cable for the laser to get a proper ohm reading from the pot.

You should take into account laser readings when unplugged. CAlibrate it, Then proceed to connect it and re-calibrate it.

I have done a couple in the past, did them unconnected. As long as they end up reading games then who cares imo, just don't go to far as it can damage discs.

I care.
Suppose you have a laser that reads 700ohm conected and 800ohm disconected.
According to theisozone and many other websites, the lower you can go is 700ohm.
If the correct reading of your laser is 700ohm, it means that it doesn't have much life left.
But if the correct reading is 800ohm, according to eugenerobinhood1, then it's ok to decrease the resistance a bit more and it should last for a few years.
That's how i see it. Sorry my english.

If your worried then go by the lowest reading. I guess thats the safest way.
