Have you desoldered the tokins from factory already ?, how you did it with hot air ?, and it was tricky ?
Hope the repair goes well, now you have a bag of tantalum capacitors like candies so is going to be a complete replacement of them
Please if you make a tutorial prepare a drawing with that trace you mentioned that connects both sides of the tokin
In some way, i have the same doubt as
@xxxmarioxxx by looking at the photos and schematics of the people that posted his "fixes" in the brazilian forum it seems some solders the capacitors in a position and other people solders them flipped, and some uses wires to "bridge" them
In the drawing i made here for psx-place forum where we was discussing all that circuits i made it the most simple posible way, but i never tested it by myself
Mate, are doubting my skills of soldering? [emoji23]
But in all seriousness, i have changed them 2 days ago, like i mentioned, i went to the 470uF 6.3V this time, works like charm.
For now, only on of the 7 NECs was replaced with tantalums, i intended to replace more further down the line, but with this busy schedule, it's kind of hard.
Anyhow, getting rid of the NECs its fairly easy, i removed them out cold (Knife Murder Technique) [emoji23]
But if you are going to remove them, without any heat, be extra careful with the traces on the mainboard, once they are removed, clean the NEC traces with the soldering iron, and apply clean solder on the traces, after that simply solder the tantalums in they're respective positions.
I never solder them flipped with the metal contacts upwards, always down, with the indications facing upwards, always at about 65° Angle between the two, gives you room and ensures they have a proper contact.
Ive also seen like you mention, that some lads put a wire to bridge the tantalum connections, or a jumper, but i don't think that particularly necessary, as it worked for me without the jumper, maybe if you replace the NECs completely, it needs a external jumper between the NECs, but ill add that to the guide as well, although i didn't tested once with a jumper, and it didn't do nothing, first time it got smoke, second time it did nothing.
Ill write a complete and extensive guide, on how to diagnose, remove and install the tantalum Capacitors.
I saw my obsession with the NECs and why, i don't assume its a Faulty PSU, mate, believe me, i have 4 working APS-227 PSUs, and none of them fixed my issue, when the original NECs were still there, and Sony does not make crappy quality PSUs, those things are almost bulletproof. [emoji23]
