    EDM-010 four failed RAM chips

    Hi everyone I have a PS5 EDM-010 disk edition blue light comes on then console shuts down. I checked uart codes using BwE code reader and it's telling me DDR6 failure bank 1, 2, 3 and 8 reball or replace. My question is has anybody else seen multiple ram failures or could this be an APU problem...

    Ps5 Freezing on Home Screen need help with error codes.

    Hi everyone I have a ps5 EDM-033 which a friend gave me the problem is even if it is left on the home screen idling it freezes after 30 minutes with a loud buzz coming from the monitor speakers. There are also no input from the controller or the on off and eject buttons when it freezes, the only...

    Ps5 PWM pin voltage to low to start fan.

    OK thanks that gives me some where to look.

    Hardware Ps5 Fan PWM signal origin.

    Yes I changed the southbridge a few hours ago and the console is acting exactly the same. I was just thinking that the southbridge is getting a signal from some where telling it to increase the duty cycle as the temperature increases.

    Hardware Ps5 Fan PWM signal origin.

    Hi I was wondering if anyone knows where the Ps5 fan PWM signal is generated, is there a specific IC that generates it.

    Ps5 PWM pin voltage to low to start fan.

    Hi I checked a working consoles against the bad consoles PWM signal with my oscilloscope I attached screen shots of both. As you can see the non working fans waveform is more of a sawtooth wave than square. They have the same frequency the non working fans duty cycle is larger probably because...

    Ps5 PWM pin voltage to low to start fan.

    I was thinking that might be the case but the temperature sensor is in the APU according to what I've read. I will check the wave form on a working console today because the bad consoles PWM waveform looks a bit odd. Thanks for your input much appreciated.

    Ps5 PWM pin voltage to low to start fan.

    Thanks for checking that. I checked the PWM signal on my oscilloscope it's not showing a square wave it looks more of a curved sawtooth wave. The amplitude is about 550mV for about 4 or 5 seconds then drops to about 220 mV same as multimeter. I will check one of my other working console tomorrow...

    Ps5 PWM pin voltage to low to start fan.

    Hi I understand that the PWM signal is a square wave and the duty cycle determins the percentage of time the voltage is on and off to the fan which controls the speed. My point is on a normal working console the voltage on the PWM pin is 550 mV when the fan is at idle speed where as on this...

    Ps5 PWM pin voltage to low to start fan.

    Hi everyone I have a Ps5 edm-030, the console starts up normally fan spins for about 10 seconds then stops. The console stays on with output to tv. I checked the voltage on the PWM pin it is 550 mV for the first 10 seconds then drops to 240 mV. I can't figure out why, if anyone has any ideas I...

    Ps5 EDM-033 no fan

    Hi everyone I brought a ps5 disk edition not working. The console turns on goes blue and to a white light I even get a message to plug in a controller and press the PS button, that stays on the screen for 6 or 7 seconds before it shuts off. I've noticed that if I turn it on a few times in...

    Ps5 CIF-1116A EDM-020 Wi-Fi Module Revision

    Hi everyone I have EDM-020 with a 1.8v short which I tracked to the Wi-Fi module, I have ordered a new module the new one is a revision 1.0 where as the bad one on my board is a revision 1.3 does anyone think this will cause a problem. Pictures of the bad module and the replacement module are...

    Ps5 CIF-1116A EDM-020 F7002 Capacitor values.

    Hi I'm new to this forum or any forum for that matter hope I'm not braking any rules. I have a Ps5 board EDM-020 i had a short on the 1.8volt line at F7002 which I traced to the Wi-Fi module, problem is I was removing capacitors to track down the short and measuring the for my notes when the cap...
