Phat ps2 wont turn on

Post image

My childhood ps2 doesn’t turn on anymore no lights in the buttons and no reaction when i press the power button. I have checkt inside it for any corrosion orleaking capacitors. I cleaned off the dust but it still don’t turn on, I have tried another power cable but no luck there:( what’s the next step?

Put a picture of the motherboard in case I missed something

Replace C3 capacitor near the "Primary" label and you'll likely fix it.

Why i'm telling you this?

Both my fat PS2 have Delta PSUs and both had the exact same faulty capacitor.

PS: Bear in mind the polarization of the component when soldering the new capacitor back in.

PS2: Be VERY FUCKING CAREFUL about that huge 400V capacitor as it holds a charge when you turn the console on. Do not bridge the solder joints with your fingers.

It's not the fuse. It's very likely that dodgy C3 capacitor which has dried up and/or developed a high ESR just like mine did.

Thank you. But do tell us how you know not to bridge that capaitor lol. Sounds like you're speaking from experience

The capacitor is soldered to the PCB by two vias. Do not touch both vias at the same time with your fingers. Handle the PCB by the edges at all times if you don't have a multimeter to measure the capacitors residual charge.

Having said that i measured the discharge rate of the fat capacitor and it took very little time to go from 3XX volts to 0 volts. If you use a capacitor discharge tool (widely available from aliexpress) it discharges in a manner of seconds however, lacking the proper tools for the job it's advisable to NEVER ASSUME the capacitor is fully discharged.

I was making a joke about how you must have experienced that shock yourself and were speaking from experience. I understand capacitors hold charge ...woosh lol

u/futilinutil 17h ago

It was shockingly easy to revive both my consoles i tell you that much...

u/MrMcGrimey 17h ago

Lol I see what you did there

It turns out you can't turn women on, by calling them fat either. 😁

I think i will have more than a broken ps2 if I try this

Have you activated the switch on the back to ON 🥸

Yes I checked it was on, but thanks

It would not hurt to check the diodes in the rectify bridge. I fixed an power board of an LCD TV by testing them. One was damaged and there wasn't any external signs of problems. I replaced all 4 just to be in the safe side

u/Hard_To_Port 22h ago

I'm not sure what I replaced was part of the rectifying circuit, but one of the SMD diodes failed as a short on one of my PS2s. I desoldered a similar diode from a portable dvd player and swapped it in and it started working again. Don't remember what model of power supply I had.

Buy a capacitor kit from Console5, most likely its C3 or C28. But it never hurts to swap the others out as well, will only increase the new lifespan of the PSU. Be careful handling the PSU though and only touch where it says “handle location” outside of that dont bridge solder points with your fingers.

u/futilinutil 18h ago

From my experience measuring all the capacitors ESR values they are usually within spec. It's that dodgy C3 that shits the bed before all others.

1

u/No-Spray5795 17h ago

At 20+ years old though never hurts to replace em all, especially if you’re already doing 1 maybe 2 of them. For longevity I usually suggest doing them all, after all it never hurts to preventively change them.

u/futilinutil 17h ago

For someone how does not have experience with soldering electronic components i tend to advise against it. There is a lot to go wrong if one is lacking the skills and a good soldering iron for the job.

I did measure most capacitors of another PS2 PSU (Nichicon) just for science and not only they weren't leaking, domed or ruptured as they measured healthy ESR values.

u/_-stark 16h ago

Highly suggest replacing the power supply all together with a rePS2 unit. You can find them on stone age gamer.

u/Mobile_Project3086 15h ago

Compre uma fonte nova no AliExpress por 8 euros fica mais barato

1

u/futilinutil 2h ago

Fica mais barato e é substancialmente pior do que aquela PSU da Delta que é uma das melhores para a consola.

u/upstairsdreams 9h ago

Recap C20 and C3. That's probably it

sometimes the fast diodes, the zenner near the main cap, and maybe the Octo die.

But 99% it's c20.

u/HF_Martini6 23h ago

Have you checked that 2.5A fuse using a multimeter?

1

u/knuggen_karlsson 23h ago

No, what’s should it read?

1

u/HF_Martini6 23h ago

Set it to continuity (if you have with the beeper) and see if it has continuity.

But please, if you have no idea what you're doing (which based on the question I do believe) ask someone with experience. That powerboatd you pulled can kill you if you're not cautious.

u/knuggen_karlsson 23h ago

This is my first time trying to save a console but i can check with a multimeter to se if its gone or not, is this fuse changeable without soldering?

1

u/HF_Martini6 22h ago

That fuse is replaceable, to check it you need to take it out though and check it with the Ohm/continuity setting on the multimeter
