PS3 not displaying image after capacitor replacement

Hi all. New here!

I recently purchased a used PS3 Phat (CECHH02) from eBay that was listed as for parts/not working. When I received it I learned it has the YLOD, after finding RIP Felix's tutorials I did a diagnosis and learned the capacitors were bad. I replaced two of them today and the PS3 now turns on with a solid green light but refuses to display an image. I tried HDMI and Composite, neither work. I also held the power button while the PS3 was off to reset the video settings. Still nothing.

Could this be the result of bridged capacitor connections? I soldered them as carefully as I could and it all looks fine, but I can't say for sure if there's a hidden bridge underneath them.

Some stuff that might be relevant: Sometimes the PS3 will beep twice while turning on, and the LED still stays green. Sometimes the power button does nothing, and the workaround is flicking the rocker switch off and back on. The PS3 happily accepts and ejects discs. And lastly, I still have the diagnostic wires soldered on (including GND to the ground plane on the motherboard).

Thank you!
 
Update: Cleaned up the capacitor soldering. Definitely no bridged connections now. Still the same problem :/

I ran more diagnostics but there were no recent errors apart from the old 1002.

Replace the other caps as well and run some wires between the ground planes then see if that works. Quite likely more than one NEC\TOKIN is bad.

Thanks for your response.

A bit of an update, I received the capacitors I ordered and I replaced all 4 tokins on the back of the board and now the PS3 is giving 3003 codes.

Felix has been assisting me in another thread but no luck so far. He reckons it might be because I'm using cheap capacitors, which is probably the case.
 
That is highly possible as well. At the very least I'd recommend some Panasonic 470uf 2.5v 2R5TPE470M9. Being an old fat model I'd replace each NEC with 6x Panasonics, bare minimum 4.

Unfortunately it would cost me over $100AUD for the panasonic capacitors through Mouser. Personally I don't think it's worth it since I only paid like 20 bucks for the PS3 and the chips are destined to fail anyway.

Mouser aren't the only place you can get them, have you looked at RS? £2 for a pack of 5. on RS another option is also HERE, or you could try using the 330uf versions you'd just need a few more of them and it would be more of a squeeze.

I have looked at other places, including RS and it's actually much more expensive than Mouser. RS would be $160AUD for 35 caps. eBay is around $80 so still not ideal considering the high chance of me damaging the system beyond repair assuming I haven't already :biggrin2:
 
You don't have to replace ALL of the caps if its not necessary (most people just do for sake of being tidy) you can replace them one at a time and test until you find the bad one(s). Normal capacitors you can only test out of circuit so I'd assume it's the same for the NECs but it would be a starting point; take all the NECs off, test them on a multimeter to find the bad ones then just order the number of tantalums you'd need to replace the bad NECs.
 
I personally do only the bottom side and usually use laptop mainboard pulled caps - they're the least likely to turn out as being fakes.
