so what's wrong?

Re: ps3, cok-002, component level repair

The console was working fine but needed to replace the nec tokins
I replaced the nec tokins on both sides with 470uf/6.4v tant caps and used socket wiring wire for the link / jumper wire

I covered up the tant caps and wire and turned on but a tant cap smoked
I removed all the tant caps and checked and re-soldered the tant caps and checked the link / jumper wire which was ok
Tried again but this time It just beeped once, and the red light disappeared
I checked the board and cant see anything burnt but the 12v line was short
I then found out the shorted components were black components (IP2003ATRPBF) (opposite the bag chips) there of them had gone. Once I eliminated them. I replaced them and no 12v short
I tried turning on but got 2 or 3 second ylod

Please any help will be really appreciated
Many Thanks

I have something that might help but its too large for here.

What do you mean
I have gone through the service manual but cant see what is generating the voltage for the rsx and cell

Are you on skype

Re: ps3, cok-002, component level repair

how many tants did you use to replace each tokin?
you need about 1200uf total - so usually people use 4x 330uf

Re: ps3, cok-002, component level repair

I tried with 16 each side. Total 32 but didn't work
Then tried 16 one side and 12 on other .
The side with 12 was the side without cell and rsx chips
And the side with the cell and tax chips have 16
I read that If it is instant ylod it could be power not getting to the cell or rsx
Do you know where the voltage is created please
Thanks

"I covered up the tant caps and wire and turned on but a tant cap smoked "
Did you observe proper cap polarity?

[lcdcaps1]

Re: ps3, cok-002, component level repair

Hi
Yes i did polarity was correct

Can anyone help me fix this Please
How can I check if voltage is getting to the cell and rsx

[stj]

Re: ps3, cok-002, component level repair

the caps are smoothing the power to the cell and rsx - meter the voltage at the caps
btw, the line on tants is positive - just incase you thought they where like polymer or electrolytic types.

Thanks , I knew that but how can i know voltage is going to the cell and rsx

Re: ps3, cok-002, component level repair

where else would it go?

Re: ps3, cok-002, component level repair

I mean what is generating it

[stj]

Re: ps3, cok-002, component level repair

well if you follow the inductors they will lead back to a fet or a chip with integrated switches.

Re: ps3, cok-002, component level repair

I have replaced so many things on this board, even added more capacitors but the same 3 second delay
can anyone help me who has repaired ps3's pls
thanks

Re: ps3, cok-002, component level repair

On the manual you can find all voltage regulators and such...Chips that have more pins and a bunch of caps around them are your low voltage regulators, the way i tested them was to probe it for a short period of time when the ps3 is on...There should be around 5 power supplies in ps3 ... 1.5v , 1.8v etc... you can find it all in manual and test it yourself

measure the resistance on the rsx and cell side towards the ground, it should be around 3ohm, if low unsolder all the bridges with wire and find out if the low resistance is on the bga side or on the regulator side,
if bga side, damaged rsx / cell
