Infinity install prob, advice needed please

[DutchDemon]

um.... isnt his ground huge? its very long on some pics, and a bit shorter on some others, but still long (i think). you know, under your chip, the big orange strip at the side of the board is all ground. scrape a bit on a piece of that, till it looks shiny, then you can solder the ground to that...
like this
hmm wait you got the glue-stuff over that... well, you might be able to get enough of that off to attach a wire...
the picture is for a v5 infinity btw, so you can compare a bit (if you didnt already have it)

further, your B wire might be touching the pad thingey behind it, but it could be just shadow
i dont have the diagram for v5 (too lazy to get it), so you'll have to check the connections yourself :P
nice sharp pics ^^ better than my camera can do :P

(btw, the glue above your chip looks yuck :P as if you sneezed or something :P)

Yeah, try putting GND to the plate at the edge of the board. That could work

you linked to my thumb

here is the link

@ spedmetal: yeah i just noticed :P

@ bluesman: you could also check if the wires on the right are actually going to the spot you intended... its easy to make a mistake with such long wires, and it's hard to check from a picture

(ok, maybe they're not long, but i've done one myself with spedmetal's short-wire competition entry (v7 infinity) as an example, so mine are a lot shorter :P (here's my install (its an old pic, the bridge you see is cleaned up and the M is fastened)(showing off feels good :P)))

How do you figure they are any shorter? Here is the V7.

Here was the short wire competition install!

EDIT: OHHHH you mean shorter them mrbluesman, sorry!

Ok, I've checked the power and ground wires for continuity using a multimeter, I put one test probe on the ground solder point on the chip and the other probe I moved around various locations on the motherboard and I got continuity every time. I then put one probe on the 3.3v solder point on the chip and the other probe on the 3.3v point on the motherboard that's shown in the installation diagram for a DMS 3, I got continuity. Therefore I must assume that my soldering is ok. The only thing I can think of doing is shortening the ground wire, (but I've already checked it for continuity). Am I to assume that I've been sent a faulty chip and do you think an email to the Matrix team is needed before I contact the supplier of the chip?

Thanks for taking the time to help guys

Regards

Continuity has nothing to do with the ground wire. You could have great continuity but is the ground wire is too long you can get what is referred to as ground bounce. The shorter your ground wire is the less likely you will get ground bounce. However I have yet to see a situation with ground bounce on the Infinity but then again my ground is always very short.

What are your exact symptoms again?

hmm, if its faulty you might be lucky to get a replacement, who did you buy the chip from? Some ppl will do a runner :| or just not email you back.

But if yours works, I mite be tempted to do mine myself, as I know (no offence meant by this) I can soldier better than that as I have been doing it for two years. But didn't want to risk messing up my ps2

But I spose I could get a cheap ps2 off ebay or somewere and give that a go, and then if it works, sell it and buy another chip...

hmm
