You're welcome
And thank you for the approval Lord NoCash

Anyways, if you do merely need to lower the voltage from 9.5V..30V to 7.5V then it might be easier to use a simple voltage regulator like "µA 78S075" (plus heatsink, otherwise it gets really hot when powering a PSone with that). The downside is that the heat is wasting energy, I don't know if your ...

Hello There forum
I like to show you what i experimenting on these past 3 weeks
I made myself a PSone (SCPH-10x) power adaptor using Buck Converter

This project came into my mind when my PSone power brick from Aliexpress decide to give my PSone constant reset ...

FINALE UPDATE
After replacing the fuse and all the caps
it still restarted itself
So i decide to buy new Power Supply
and guess what...
IT WORKS FULLY, FINALLY
And the psone goes to the main menu and play the gameplay demo
I call this a success fix
Big Thank you acid juice and Shadow for helping ...

I did a better reading of the post and I think I found your current problem: reader wear.

When moving the potentiometer of the reader, you reduced the voltage sent to the lens and because of that it is no longer able to read properly, so it is crashing on the PS screen sometimes.

when it reads ...

reply for TEddy69
Everything indicates that it is a problem with the optical set of the device, if you want to confirm do the following, connect only the white wire of the reader to the board, turn on the device, press the button that turns the reader on and see if it turns off, if it stays making ...

Oh yes
This is for Acid Juice
i forgot to tell you the resistance test fir the switches (Big soz)
(And sorry i cant photo it cuz hands are full)
My Psone Power supply voltage : 7.8 Volt

Power button on No Power : 0.01 ohm
Power button with power : 0.05 ohm
Pressed Power button with power and video ...

I had this problem on one of my psones.

in my case it was a problem with the power button, it was acting as a resistor limiting the voltage and current coming out of the button. in that case, it would be necessary to replace it or do the easiest thing, dismantle it, clean it with isopropyl ...

Quite an interesting problem. I want to say it's probably power supply related. There might be a short on the drive mechanics somewhere which causes it to brownout and restart.


I see
My first suspicious was the power supply
cuz when i put the PSone upside down it start to accept the disk and ...

Got my psone ntsc-j (SCPH-103) in my attic
Boots normally when there no cd in it
but after i put a disc in it constantly restart itself
Video :

is there any way to fix it ?

Is this support PM-41 board on SCPH-103 PSone Slim ?
cuz i really want to use my arduino mini on this
