Need some info on scph50003 - its V9 right ?

ughggghhhhhhhhhh

read up about the romeo mod, doesnt look to hard, i'll just do that first. i have a multimeter so can check the resistance. says it should be between 4 to 5 ohms.

so its true that only a small batch of the consoles got the problem? i guess its better not to take the risk, as ive got nothing to lose by doing the mod, in fact, everything to gain, unless i do it wrong (which i wont )

so is this all i need to know? the romeo mod?

They've all got the LA6508 problem - and if you aren't careful, you'll scortch the board, ruin the pad and break the leg off of the chip. Find a scrap board you can use to practice lifting the chip legs from. You also have to solder the 5v point to a VIA so if you aren't sufficient at soldering those (there are 3 others to do on a v9 also) then I wouldn't even attempt trying.

scortch the board as in... ?

i know it will require someskill, but for the VIA's all i need is patience and precision. i have a flux pen etc, so it shouldnt be so hard this time around. i do have a scrap board i can practise on though.

can you direct me to a concise instruction on how to do a romeo mod? is it just the one wire ? in the "post your pics here" thread, most of the romeo fixes seemed to have 2?

Scortch the board as in burn it when lifting the pin.

The reason most romeos appear to have 2 wires, is because the wire should be bent down below the laser optical cable input to the motherboard to avoid the noise from the cable interfering with the power to the LA6508

The best thing is to practice lifting every 3rd pin of the BA chip on that scrap board of yours and then bending it up, soldering a wire to the lifted pin and finding a VIA to solder the wire to.

Hope this helps...

whoah whoah slow down mate. what exactly is the BA chip ?



thats the V10, its from a site where they tell you all about the LA6508 problem. is the V9 much different? which IC pin do i have to lift? is there a site with instructions, or can you show me?

thanks mate.

The scrap board you have will probably have a BA chip which you can practice on before doing the LA on the real board.

The v9 is different in that the point is a large VIA rather than the other points shown on the v10...

well you were being very vague, but i eventually found the romeo mod instructions.

3rd pin down from the corner the faces the center of the board, and connect that to a "VIA" on the inverse side, through the hole to the right. i have closeup pics. VIA's are the little round pads right?

so the idea is to lift the pin of the LA chip, right? the whole point is to replace the Vin with 5v1 from 12v right? So all i have to do is heat the base of the leg, and use a needle-nose plier to lift the leg? ive done this many times before, shouldnt be too hard, i have lots of trashed circuit boards in my house to practise on (but just 1 ps2 board).
